Full Text
The present invention relates to a compound, or pharmaceutically acceptable salt thereof and pharmaceutical composition comprising the same.
The present invention relates to substituted pyrimidine derivatives. In particular, the invention relates to [4-(3-substituted-phenyl)-pyrimidin-2-yl]-phenyl-amines and [4-(3-substituted-phenyl)-pyrimidin-2-yl]-(pyridine-3-yl)-amines and their use in therapy. More specifically, but not exclusively, the invention relates to compounds that are capable of inhibiting one or more protein kinases.
BACKGROUND TO THE INVENTION
In eukaryotes, all biological functions, including DNA replication, cell cycle progression, energy metabolism, and cell growth and differentiation, are regulated through the reversible phosphorylation of proteins. The phosphorylation state of a protein determines not only its function, subcellular distribution, and stability, but also what other proteins or cellular components it associates with. The balance of specific phosphorylation in the proteome as a whole, as well as of individual members in a biochemical pathway, is thus used by organisms as a strategy to maintain homeostasis in response to an ever-changing environment. The enzymes that carry out these phosphorylation and dephosphorylation steps are protein kinases and phosphatases, respectively.
The eukaryotic protein kinase family is one of the largest in the human genome, comprising some 500 genes [1,2]. The majority of kinases contain a 250-300 amino acid residue catalytic domain with a conserved core structure. This domain comprises a blading pocket for ATP (less frequently GTP), whose terminal phosphate group the kinase transfers covalently to its macromolecular substrates. The phosphate donor is always bound as a complex with a divalent ion (usually Mg2+or Mn2+). Another important function of the catalytic domain is the binding and orientation for phosphotransfer of the macromolecular substrate. The catalytic domains present in most kinases are more or less homologous.

A wide variety of molecules capable of inhibiting protein kinase function through
antagonising ATP binding are known in the art [3-7]. By way of example, the applicant has
previously disclosed 2-anihno^-heteroaryl-pyrimidine compounds with kinase inhibitory
properties, particularly against cyclin-dependent kinases (CDKs) [8-12]. CDKs are
serine/threonine protein kinases that associate with various cyclin subunits. These
complexes are important for the regulation of eukaryotic cell cycle progression, but also
for the regulation of transcription [13,14].
The present invention seeks to provide [4-(3-substituted-phenyl)-pyrimidin-2-yl]-phenylamines
and [4-(3-substituted-phenyl)-pyrmii6^-2-yl]-(pyridine-3-yl)-amines. More
specifically, the invention relates to compounds that have broad therapeutic applications in
the treatment of a number of different diseases and/or that are capable of inhibiting one or
more protein kinases.

DETAILED DESCRIPTION
As used herein, the term "hydrocarbyl" refers to a group comprising at least C and H. If the
hydrocarbyl group comprises more than one C then those carbons need not necessarily be
linked to each other. For example, at least two of the carbons may be linked via a suitable
element or group. Thus, the hydrocarbyl group may contain heteroatoms. Suitable
heteroatoms will be apparent to those skilled in the art and include, for instance, sulphur,
nitrogen, oxygen, phosphorus and silicon. Where the hydrocarbyl group contains one or
more heteroatoms, the group may be linked via a carbon atom or via a heteroatom to
another group, i.e. the linker atom may be a carbon or a heteroatom. Preferably, the
hydrocarbyl group is an aryl, heteroaryl, alkyl, cycloalkyl, aralkyl, alicyclic, heteroalicyclic
or alkenyl group. More preferably, the hydrocarbyl group is an aryl, heteroaryl, alkyl,
cycloalkyl, aralkyl or alkenyl group. The hydrocarbyl group may be optionally substituted
by one or more R11 groups.
As used herein, the term "alkyl" includes both saturated straight chain and branched alkyl
groups which may be substituted (mono- or poly-) or unsubstituted. Preferably, the alkyl
group is a €1-20 alkyl group, more preferably a CMS, more preferably still a CMZ alkyl
group, more preferably still, a Ci-e alkyl group, more preferably a Ci-3 alkyl group.
Particularly preferred alkyl groups include, for example, methyl, ethyl, propyl, isopropyl,
butyl, isobutyl, tert-butyl, pentyl and hexyl. Suitable substituents include, for example,
one or more R11 groups. Preferably, the alkyl group is unsubstituted.

THERAPEUTIC USE
The compounds of the present invention have been found to possess anti-proliferative
activity and are therefore believed to be of use in the treatment of proliferative disorders
such as cancers, leukaemias and other disorders associated with uncontrolled cellular
proliferation such as psoriasis and restenosis. As defined herein, an anti-proliferative effect
within the scope of the present invention may be demonstrated by the ability to inhibit cell
proliferation in an in vitro whole cell assay, for example using any of the cell lines A549,
HT29 or Saos-2 Using such assays it may be determined whether a compound is antiproliferative
in the context of the present invention.
One preferred embodiment of the present invention therefore relates to the use of one or
more compounds of the invention in the preparation of a medicament for treating a
proliferative disorder.
As used herein the phrase "preparation of a medicament" includes the use of a compound
of the invention directly as the medicament in addition to its use in a screening programme
for further therapeutic agents or in any stage of the manufacture of such a medicament.
Preferably, the proliferative disorder is a cancer or leukaemia. The term proliferative
disorder is used herein in a broad sense to include any disorder that requires control of the
cell cycle, for example cardiovascular disorders such as restenosis, cardiomyopathy and
myocardial infarction, auto-immune disorders such as glomerulonephritis and rheumatoid
arthritis, dermatological disorders such as psoriasis, anti-inflammatory, anti-fungal,
antiparasitic disorders such as malaria, emphysema, alopecia, and chronic obstructive
pulmonary disorder. In these disorders, the compounds of the present invention may
induce apoptosis or maintain stasis within the desired cells as required.
The compounds of the invention may inhibit any of the steps or stages in the cell cycle, for
example, formation of the nuclear envelope, exit from the quiescent phase of the cell cycle
(GO), Gl progression, chromosome decondensation, nuclear envelope breakdown, START,
initiation of DNA replication, progression of DNA replication, termination of DNA
replication, centrosome duplication, G2 progression, activation of mitotic or meiotic
functions, chromosome condensation, centrosome separation, microtubule nucleation,
spindle formation and function, interactions with microtubule motor proteins, chromatid
separation and segregation, inactivation of mitotic functions, formation of contractile ring,
and cytokinesis functions. In particular, the compounds of the invention may influence
certain gene functions such as chrornatin binding, formation of replication complexes,
replication licensing, phosphorylation or other secondary modification activity, proteolytic
degradation, microtubule binding, actin binding, septin binding, microtubule organising
centre nucleation activity and binding to components of cell cycle signalling pathways.
In one embodiment of the invention, the compound of the invention is administered in an
amount sufficient to inhibit at least one CDK enzyme.
Preferably, the compound of the invention is administered in an amount sufficient to
inhibit at least one of CDK2 and/or CDK4.
Another aspect of the invention relates to the use of a compound of the invention in the
preparation of a medicament for treating a viral disorder, such as human cytomegalovirus
(HCMV), herpes simplex virus type 1 (HSV-1), human immunodeficiency virus type 1
(HTV-1), and varicella zoster virus (VZV).
In a more preferred embodiment of the invention, the compound of the invention is
administered in an amount sufficient to inhibit one or more of the host cell CDKs involved
in viral replication, i.e. CDK2, CDK7, CDKS, and CDK9 [23].
As defined herein, an anti-viral effect within the scope of the present invention may be
demonstrated by the ability to inhibit CDK2, CDK7, CDKS or CDK9.
In a particularly preferred embodiment, the invention relates to the use of one or more
compounds of the invention in the treatment of a viral disorder which is CDK dependent or
sensitive. CDK dependent disorders are associated with an above normal level of activity
of one or more CDK enzymes. Such disorders preferably associated with an abnormal
level of activity of CDK2, CDK7, CDK8 and/or CDK9. A CDK sensitive disorder is a
disorder in which an aberration in the CDK level is not the primary cause, but is
downstream of the primary metabolic aberration. In such scenarios, CDK2, CDK7, CDK8
and/or CDK9 can be said to be part of the sensitive metabolic pathway and CDK inhibitors
may therefore be active in treating such disorders.
A further aspect of the invention relates to a method of treating a CDK-dependent disorder,
said method comprising administering to a subject in need thereof, a compound according
to the invention, or a pharmaceutically acceptable salt thereof, as defined above in an
amount sufficient to inhibit a cyclin dependent kinase.
Preferably, the CDK-dependent disorder is a viral disorder or a proliferative disorder, more
preferably cancer.
Another aspect of the invention relates to the use of compounds of the invention, or
pharmaceutically accetable salts thereof, in the preparation of a medicament for treating
diabetes.
In a particularly preferred embodiment, the diabetes is type n diabetes.
GSK3 is one of several protein kinases that phosphorylate glycogen synthase (GS). The
stimulation of glycogen synthesis by insulin in skeletal muscle results from the
dephosphorylation and activation of GS. GSKS's action on GS thus results in the latter's
deactivation and thus suppression of the conversion of glucose into glycogen in muscles.
Type n diabetes (non-insulin dependent diabetes mellitus) is a multi-factorial disease.
Hyperglycaemia is due to insulin resistance in the liver, muscles, and other tissues, coupled
with impaired secretion of insulin. Skeletal muscle is the main site for insulin-stimulated
glucose uptake, there it is either removed from circulation or converted to glycogen.
Muscle glycogen deposition is the main determinant in glucose homeostasis and type n
diabetics have defective muscle glycogen storage. There is evidence that an increase in
GSK3 activity is important in type II diabetes [24]. Furthermore, it has been demonstrated
that GSK3 is over-expressed in muscle cells of type n diabetics and that an inverse
correlation exists between skeletal muscle GSK3 activity and insulin action [25].
GSK3 inhibition is therefore of therapeutic significance in the treatment of diabetes,
particularly type II, and diabetic neuropathy.
It is notable that GSK3 is known to phosphorylate many substrates other than GS, and is
thus involved in the regulation of multiple biochemical pathways. For example, GSK is
highly expressed in the central and peripheral nervous systems.
Preferably, the compound is administered in an amount sufficient to inhibit GSK, more
preferably GSK3, more preferably still GSK30.
Another aspect of the invention therefore relates to the use of compounds of the invention,
or pharmaceutically acceptable salts thereof, in the preparation of a medicament for
treating a CNS disorders, for example neurodegenerative disorders.
Preferably, the CNS disorder is Alzheimer's disease. Tau is a GSK-3 substrate which has been implicated in the etiology of Alzheimer's disease.
In healthy nerve cells, Tau co-assembles with tubulin into microtubules. However, in
Alzheimer's disease, tau forms large tangles of filaments, which disrupt the microtubule
structures in the nerve cell, thereby impairing the transport of nutrients as well as the
transmission of neuronal messages.
Without wishing to be bound by theory, it is believed that GSK3 inhibitors may be able to
prevent and/or reverse the abnormal hyperphosphorylation of the microtubule-associated
protein tau that is an invariant feature of Alzheimer's disease and a number of other
neurodegenerative diseases, such as progressive supranuclear palsy, corticobasal
degeneration and Pick's disease. Mutations in the tau gene cause inherited forms of frontotemporal
dementia, further underscoring the relevance of tau protein dysfunction for the
neurodegenerative process [26].
Another aspect of the invention relates to the use of compounds of the invention, or
pharmaceutically acceptable salts thereof, in the preparation of a medicament for treating
bipolar disorder.
Yet another aspect of the invention relates to the use of compounds of the invention, or
pharmaceutically acceptable salts thereof, in the preparation of a medicament for treating a
stroke.
Reducing neuronal apoptosis is an important therapeutic goal in the context of head
trauma, stroke, epilepsy, and motor neuron disease [27]. Therefore, GSK3 as a proapoptotic
factor in neuronal cells makes this protein kinase an attractive therapeutic target
for the design of inhibitory drugs to treat these diseases.
Yet another aspect of the invention relates to the use of compounds of the invention, or
pharmaceutically acceptable salts thereof, in the preparation of a medicament for treating
alopecia. '"
Hair growth is controlled by the Wnt signalling pathway, in particular Wnt-3. In tissueculture
model systems of the skin, the expression of non-degradable mutants of p-catenin
leads to a dramatic increase in the population of putative stem cells, which have greater
proliferative potential [28]. This population of stem cells expresses a higher level of noncadherin-
associated p-catenin [29], which may contribute to their high proliferative
potential. Moreover, transgenic mice overexpressing a truncated p-catenin in the skin
undergo de novo hair-follicle morphogenesis, which normally is only established during
embryogenesis. The ectopic application of GSK3 inhibitors may therefore be
therapeutically useful in the treatment of baldness and in restoring hair growth following
chemotherapy-induced, alopecia.
A further aspect of the invention relates to a method of treating a GSK3-dependent
disorder, said method comprising administering to a subject in need thereof, a compound
according to the invention, or a pharmaceutically acceptable salt thereof, as defined above
in an amount sufficient to inhibit GSK3.
Preferably, the GSK3-dependent disorder is diabetes.
Preferably, the compound of the invention, or pharmaceutically acceptable salt thereof, is
administered in an amount sufficient to inhibit GSK3j3.
In one embodiment of the invention, the compound of the invention is administered in an
amount sufficient to inhibit at least one PLK enzyme.
The polo-Eke khiases (PLKs) constitute a family of serine/threorune protein kinases.
Mitotic Drosophila melanogaster mutants at the polo locus display spindle abnormalities
[30] and polo was found to encode a mitotic kinase [31]. In humans, there exist three
closely related PLKs [32]. They contain a highly homologous amino-terrninal catalytic
kinase domain and their carboxyl termini contain two or three conserved regions, the polo
boxes. The function of the polo boxes remains incompletely understood but they are
implicated in the targeting of PLKs to subcellular compartments [33,34], mediation of
interactions with other proteins [35], or may constitute part of an autoregulatory domain
[36]. Furthermore, the polo box-dependent PLK1 activity is required for proper
metaphase/anaphase transition and cytokinesis [37,38].
Studies have shown that human PLKs regulate some fundamental aspects of mitosis
[39,40]. In particular, PLK1 activity is believed to be necessary for the functional
maturation of centrosomes in late G2/early prophase and subsequent establishment of a
bipolar spindle. Depletion of cellular PLK1 through the small interfering RNA (siRNA)
technique has also confirmed that this protein is required for multiple mitotic processes and
completion of cytokinesis [41].
In a more preferred embodiment of the invention, the compound of the invention is
administered in an amount sufficient to inhibit PLK1.
Of the three human PLKs, PLK1 is the best characterized; it regulates a number of cell
division cycle effects, including the onset of mitosis [42,43], DNA-damage checkpoint
activation [44,45], regulation of the anaphase promoting complex [46-48], phosphorylation
of the proteasome [49], and centrosome duplication and maturation [50].
Specifically, initiation of mitosis requires activation of M-phase promoting factor (MPF),
the complex between the cyclin dependent kinase CDK1 and B-type cyclins [51]. The
latter accumulate during the S and G2 phases of the cell cycle and promote the inhibitory
phosphorylation of the MPF complex by WEE1, MIK1, and MYT1 kinases. At the end of
the G2 phase, corresponding dephosphorylation by the dual-specificity phosphatase
CDC25C triggers the activation of MPF [52]. In interphase, cyclin B localizes to the
cytoplasm [53], it then becomes phosphorylated during prophase and this event causes
nuclear translocation [54,55]. The nuclear accumulation of active MPF during prophase is
thought to be important for initiating M-phase events [56]. However, nuclear MPF is kept
inactive by WEE1 unless counteracted by CDC25C. The phosphatase CDC25C itself,
localized to the cytoplasm during interphase, accumulates in the nucleus in prophase [57-
59]. The nuclear entry of both cyclin B [60] and CDC25C [61] are promoted through
phosphorylation by PLK1 [43]. This kinase is an important regulator of M-phase initiation.
In one particularly preferred embodiment, the compounds of the invention are ATPantagonistic
inhibitors of PLK1.
In the present context ATP antagonism refers to the ability of an inhibitor compound to
diminish or prevent PLK catalytic activity, i.e. phosphotransfer from ATP to a
macromolecular PLK substrate, by virtue of reversibly or irreversibly binding at the
enzyme's active site in such a manner as to impair or abolish ATP binding.
In another preferred embodiment, the compound of the invention is administered in an
amount sufficient to inhibit PLK2 and/or PLK3.
Mammalian PLK2 (also known as SNK) and PLK3 (also known as PRK and FNK) were
originally shown to be immediate early gene products. PLK3 kinase activity appears to
peak during late S and G2 phase. It is also activated during DNA damage checkpoint
activation and severe oxidative stress. PLK3 also plays an important role in the regulation
of microtubule dynamics and centrosome function in the cell and deregulated PLK3
expression results in cell cycle arrest and apoptosis [62]. PLK2 is the least well understood
homologue of the three PLKs. Both PLK2 and PLK3 may have additional important postmitotic
functions [35].
A further aspect of the invention relates to a method of treating a PLK-dependent disorder,
said method comprising administering to a subject hi need thereof, a compound according
to the invention, or a pharmaceutically acceptable salt thereof, as defined above in an
amount sufficient to inhibit PLK.
Preferably, the PLK-dependent disorder is a proliferative disorder, more preferably cancer.
Preferably, the compound of the invention, or pharmaceutically acceptable salt thereof, is
administered in an amount sufficient to inhibit aurora kinase.
A further aspect of the invention relates to a method of treating an aurora kinase-dependent
disorder, said method comprising administering to a subject in need thereof, a compound
according to the invention, or a pharmaceutically acceptable salt thereof, as defined above
in an amount sufficient to inhibit aurora kinase.
Preferably, the aurora kinase dependent disorder is a viral disorder as defined above.

compound of the invention as defined above admixed with one or more pharmaceutically
acceptable diluents, excipients or carriers. Even though the compounds of the present
invention (including their pharmaceutically acceptable salts, esters and pharmaceutically
acceptable solvates) can be administered alone, they will generally be administered in
admixture with a pharmaceutical carrier, excipient or diluent, particularly for human
therapy. The pharmaceutical compositions may be for human or animal usage in human
and veterinary medicine.
Examples of such suitable excipients for the various different forms of pharmaceutical
compositions described herein may be found in the "Handbook of Pharmaceutical
Excipients, 2nd Edition, (1994), Edited by A Wade and PJ Weller.

SALTS/ESTERS
The compounds of the invention can be present as salts or esters, hi particular
pharmaceutically acceptable salts or esters.
Pharmaceutically acceptable salts of the compounds of the invention include suitable acid
addition or base salts thereof. A review of suitable pharmaceutical salts may be found in
Berge et al, J Pharm Sci, 66, 1-19 (1977). Salts are formed, for example with strong
inorganic acids such as mineral acids, e.g. sulphuric acid, phosphoric acid or hydrohalic
acids; with strong organic carboxylic acids, such as alkanecarboxylic acids of 1 to 4 carbon
atoms which are unsubstiruted or substituted (e.g., by halogen), such as acetic acid; with
saturated or unsaturated dicarboxylic acids, for example oxalic, malonic, succinic, maleic,
fumaric, phthalic or tetraphthalic; with hydroxycarboxylic acids, for example ascorbic,
glycolic, lactic, malic, tartaric or citric acid; with aminoacids, for example aspartic or
glutamic acid; with benzoic acid; or with organic sulfonic acids, such as (Ci-C4)-alkyl- or
aryl-sulfonic acids which are unsubstituted or substituted (for example, by a halogen) such
as methane- or p-toluene sulfonic acid.
Esters are formed either using organic acids or alcohols/hydroxides, depending on the
functional group being esterified. Organic acids include carboxylic acids, such as
alkanecarboxylic acids of 1 to 12 carbon atoms which are unsubstituted or substituted (e.g.,
by halogen), such as acetic acid; with saturated or unsaturated dicarboxylic acid, for
example oxalic, malonic, succinic, maleic, fumaric, phthalic or tetraphthalic; with
hydroxycarboxylic acids, for example ascorbic, glycolic, lactic, malic, tartaric or citric
acid; with aminoacids, for example aspartic or ghitamic acid; with benzoic acid; or with
organic sulfonic acids, such as (Ci-C^-alkyl- or aryl-sulfonic acids which are
unsubstituted or substituted (for example, by a halogen) such as methane- or p-toluene
sulfonic acid. Suitable hydroxides include inorganic hydroxides, such as sodium
hydroxide, potassium hydroxide, calcium hydroxide, aluminium hydroxide. Alcohols
include alkanealcohols of 1-12 carbon atoms which may be unsubstituted or substituted,
e.g. by a halogen).
ENANTIOMERS/TAUTOMERS
In all aspects of the present invention previously discussed, the invention includes, where
appropriate all enantiomers and tautomers of compounds of the invention. The man skilled
in the art will recognise compounds that possess an optical properties (one or more chiral
carbon atoms) or tautomeric characteristics. The corresponding enantiomers and/or
tautomers may be isolated/prepared by methods known in the art.
STEREO AND GEOMETRIC ISOMERS
Some of the compounds of the invention may exist* as stereoisomers and/or geometric
isomers - e.g. they may possess one or more asymmetric and/or geometric centres and so
may exist in two or more stereoisomeric and/or geometric forms. The present invention
contemplates the use of all the individual stereoisomers and geometric isomers of those
agents, and mixtures thereof. The terms used in the claims encompass these forms,
provided said forms retain the appropriate functional activity (though not necessarily to the
same degree).
The present invention also includes all suitable isotopic variations of the agent or
pharmaceutically acceptable salt thereof. An isotopic variation of an agent of the present
invention or a pharmaceutically acceptable salt thereof is defined as one hi which at least
one atom is replaced by an atom having the same atomic number but an atomic mass
different from the atomic mass usually found in nature. Examples of isotopes that can be
incorporated into the agent and pharmaceutically acceptable salts thereof include isotopes
of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur, fluorine and chlorine such as
2H, 3H, 13C, 14C, 15N, 170,180,31P, 32P, 35S, 18F and 36C1, respectively. Certain isotopic
variations of the agent and pharmaceutically acceptable salts thereof, for example, those in
which a radioactive isotope such as 3H or 14C is incorporated, are useful in drug and/or
substrate tissue distribution studies. Tritiated, i.e., 3H, and carbon-14, i.e., 14C, isotopes are
particularly preferred for then: ease of preparation and detectability. Further, substitution
with isotopes such as deuterium, i.e., 2H, may afford certain therapeutic advantages
resulting from greater metabolic stability, for example, increased hi vivo half-life or
reduced dosage requirements and hence may be preferred in some circumstances. Isotopic
variations of the agent of the present invention and pharmaceutically acceptable salts
thereof of this invention can generally be prepared by conventional procedures using
appropriate isotopic variations of suitable reagents.
SOLVATES
The present invention also includes the use of solvate forms of the compounds of the
present invention. The terms used in the claims encompass these forms.
POLYMORPHS
The invention furthermore relates to the compounds of the present invention hi their
various crystalline forms, polymorphic forms and (an)hydrous forms. It is well established
within the pharmaceutical industry that chemical compounds may be isolated in any of
such forms by slightly varying the method of purification and or isolation form the
solvents used in the synthetic preparation of such compounds.
PRODRUGS
The invention further includes the compounds of the present invention in prodrug form.
Such prodrugs are generally compounds of the invention wherein one or more appropriate
groups have been modified such that the modification may be reversed upon
administration to a human or mammalian subject. Such reversion is usually performed by
an enzyme naturally present in such subject, though it is possible for a second agent to be
administered together with such a prodrug in order to perform the reversion in vivo.
Examples of such modifications include ester (for example, any of those described above),
wherein the reversion may be carried out be an esterase etc. Other such systems will be
well known to those skilled in the art.
ADMINISTRATION
The pharmaceutical compositions of the present invention may be adapted for oral, rectal,
vaginal, parenteral, intramuscular, intraperitoneal, intraarterial, intrathecal, intrabronchial,
subcutaneous, intradermal, intravenous, nasal, buccal or sublingual routes of
administration.
For oral administration, particular use is made of compressed tablets, pills, tablets, gellules,
drops, and capsules. Preferably, these compositions contain from 1 to 250 mg and more
preferably from 10-100 mg, of active ingredient per dose.
Other forms of administration comprise solutions or emulsions which may be injected
intravenously, intraarterially, intrathecally, subcutaneously, intradermally, intraperitoneally
or intramuscularly, and which are prepared from sterile or sterilisable solutions. The
pharmaceutical compositions of the present invention may also be in form of suppositories,
pessaries, suspensions, emulsions, lotions, ointments, creams, gels, sprays, solutions or
dusting powders.
An alternative means of transdermal administration is by use of a skin patch. For example,
the active ingredient can be incorporated into a cream consisting of an aqueous emulsion of
polyethylene glycols or liquid paraffin. The active ingredient can also be incorporated, at a
concentration of between 1 and 10% by weight, into an ointment consisting of a white wax
or white soft paraffin base together with such stabilisers and preservatives as may be
required.
f
Injectable forms may contain between 10-1000 mg, preferably between 10-250 mg, of
active ingredient per dose.
Compositions may be formulated in unit dosage form, i.e., in the form of discrete portions
containing a unit dose, or a multiple or sub-unit of a unit dose.
DOSAGE
A person of ordinary skill in the art can easily determine an appropriate dose of one of the
instant compositions to administer to a subject without undue experimentation. Typically, a
physician will determine the actual dosage which will be most suitable for an individual
patient and it will depend on a variety of factors including the activity of the specific
compound employed, the metabolic stability and length of action of that compound, the
age, body weight, general health, sex, diet, mode and time of administration, rate of
excretion, drug combination, the severity of the particular condition, and the individual
undergoing therapy. The^ dosages disclosed herein are exemplary of the average case.
There can of course be individual instances where higher or lower dosage ranges are
merited, and such are within the scope of this invention.
Depending upon the need, the agent may be administered at a dose of from 0.01 to 30
mg/kg body weight, such as from 0.1 to 10 mg/kg, more preferably from 0.1 to 1 mg/kg
body weight.
In an exemplary embodiment, one or more doses of 10 to 150 mg/day will be administered
to the patient.
COMBINATIONS
In a particularly preferred embodiment, the one or more compounds of the invention are
administered in combination with one or more other therapeutically active agents, for
example, existing drugs available on the market. In such cases, the compounds of the
invention may be administered consecutively, simultaneously or sequentially with the one
or more other active agents.
By way of example, it is known that anticancer drugs in general are more effective when
used in combination.- In particular, combination therapy is desirable in order to avoid an
overlap of major toxicities, mechanism of action and resistance mechanism(s).
Furthermore, it is also desirable to administer most drugs at their maximum tolerated doses
with minimum time intervals between such doses. The major advantages of combining
chemotherapeutic drugs are that it may promote additive or possible synergistic effects
through biochemical interactions and also may decrease the emergence of resistance in
early tumor cells which would have been otherwise responsive to initial chemotherapy
with a single agent. An example of the use of biochemical interactions in selecting drug
combinations is demonstrated by the administration of leucovorin to increase the binding
of an active intracellular metabolite of 5-fluorouracil to its target, thymidylate synthase, '
thus increasing its cytotoxic effects.
Numerous combinations are used in current treatments of cancer and leukemia. A more
extensive review of medical practices may be found in "Oncologic Therapies" edited by E.
E. Yokes and H. M. Golomb, published by Springer.
Beneficial combinations may be suggested by studying the growth inhibitory activity of
the test compounds with agents known or suspected of being valuable in the treatment of a
particular cancer initially or cell lines derived from that cancer. This procedure can also be
used to determine the order of administration of the agents, i.e. before, simultaneously, or
after delivery. Such scheduling may be a feature of all the cycle acting agents identified
herein.

of acetonitrile in water (containing 0.1 % CFsCOOH) as indicated, followed by isocratic

Kinase assays
j
The compounds from the examples ahove were investigated for their ability to inhibit the
enzymatic activity of various protein kinases. This was achieved by measurement of
incorporation of radioactive phosphate from ATP into appropriate polypeptide substrates.
Recombinant protein kinases and kinase complexes were produced or obtained
commercially. Assays were performed using 96-well plates and appropriate assay buffers
(typically 25 mM p-glycerophosphate, 20 mM MOPS, 5 mM EGTA, 1 mM DTT, 1 mM
Na3VO3, pH 7.4), into which were added 2 - 4 jj.g of active enzyme with appropriate
substrates. The reactions were initiated by addition of Mg/ATP mix (15 mM MgCl2 + 100
HM ATP with 30-50 kBq per well of [y-32P]-ATP) and mixtures incubated as required at
30 °C. Reactions were stopped on ice, followed by filtration through p81 filterplates or
GF/C filterplates (Whatman Polyfiltronics, Kent, UK). After washing 3 times with 75 mM
aq orthophosphoric acid, plates were dried, scintillant added and incorporated radioactivity
measured in a scintillation counter (TopCount, Packard Instruments, Pangbourne, Berks,
UK). Compounds for kinase assay were made up as 10 mM stocks in DMSO and diluted
into 10 % DMSO in assay buffer. Data was analysed using curve-fitting software
(GraphPad Prism version 3.00 for Windows, GraphPad Software, San Diego California
USA) to determine ICso values (concentration of test compound which inhibits kinase
activity by 50 %.). ICso values for selected compounds of the invention are shown in Table
1.
MTT cvtotoxicity assay
The compounds from the examples above were subjected to a standard cellular
proliferation assay using human tumour cell lines obtained from the ATCC (American
Type Culture Collection, 10801 University Boulevard, Manessas, VA 20110-2209, USA).
Standard 72-h MTT (thiazolyl blue; 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium
bromide) assays were performed [67, 68]. hi short: cells were seeded into 96-well plates
according to doubling time and incubated overnight at 37 °C. Test compounds were made
up in DMSO and a 1/3 dilution series prepared in 100 uL cell media, added to cells (in
triplicates) and incubated for 72 ho at 37 °C. MTT was made up as a stock of 5 mg/mL in
cell media and filter-sterilised. Media was removed from cells followed by a wash with
200 jjL PBS, MTT solution was then added at 20 uL per well and incubated in the dark at
37 °C for 4 h. MTT solution was removed and cells again washed with 200 uL PBS. MTT
dye was solubilised with 200 jiL per well of DMSO with agitation. Absorbance was read at
540 nm and data analysed using curve-fitting software (GraphPad Prism version 3.00 for
Windows, GraphPad Software, San Diego California USA) to determine ICso values
(concentration of test compound which inhibits cell growth by 50 %). IC50 values for
selected compounds of the invention are shown in Table 2.
Various modifications and variations of the described aspects of the invention will be
apparent to those skilled in the art without departing from the scope and spirit of the
invention. Although the invention has been described in connection with specific preferred
embodiments, it should be understood that the invention as claimed should not be unduly
limited to such specific embodiments. Indeed, various modifications of the described
modes of carrying out the invention which are obvious to those skilled in the relevant
fields are intended to be within the scope of the following claims.
