Full Text DESCRIPTION
DIAMINE DERIVATIVES
TECHNICAL FIELD
The present invention relates to novel compounds
which inhibit activated blood coagulation factor X
(hereinafter abbreviated as "FXa") to exhibit a potent
anticoagulant effect and can be orally administered, and
anticoagulants or agents for preventing and/or treating
thrombosis or embolism, which comprise such a novel
compound as an active ingredient.
BACKGROUND ART
In unstable angina, cerebral infarction, cerebral
embolism, myocardial infarction, pulmonary infarction,
pulmonary embolism, Buerger's disease, deep venous
thrombosis, disseminated intravascular coagulation
syndrome, thrombus formation after valve replacement,
reocclusion after angioplasty and thrombus formation
during extracorporeal circulation, hypercoagulable state
is a pivotal factor. Therefore, there is a demand for
development of excellent anticoagulants which have good
dose responsiveness, long duration, low risk of hemorrhage
and little side effects and fast onset of sufficient
effects even by oral administration (Thrombosis Research,
Vol. 68, pp. 507-512, 1992).
Based on the research of anticoagulants worked
through various mechanism of action, it is suggested that
FXa inhibitors are promising anticoagulants. A blood
coagulation system comprises a series of reactions that a
great amount of thrombin is produced through an
amplification process by multi-stage enzyme reactions to
form insoluble fibrin. In an endogenous system, activated
factor IX activates into factor X on a phospholipid
membrane in the presence of activated factor VIII and
calcium ions after multi-stage reactions subsequent to
activation of a contact factor. In an exogenous system,
activated factor VII activates factor X in the presence of
a tissue factor. More specifically, the activation of .the
factor X into FXa in the coagulation system is a crucial
reaction in the formation of thrombin. The activated
factor X (FXa) limitedly decomposes prothrombin to produce
thrombin in the both systems. Since the produced thrombin
activates coagulation factors in the upper stream, the
formation of thrombin is more amplified. As described
above, since the coagulation system in the upper stream of
FXa is divided into the endogenous system and the
exogenous system, production of FXa cannot be sufficiently
inhibited by inhibiting enzymes in the coagulation system
in the upper stream of FXa, leading to production of
thrombin. Since the coagulation system comprises selfamplification
reactions, inhibition of the coagulation
system can be more efficiently achieved by inhibiting FXa
in the upper stream of thrombin than the inhibition of
thrombin (Thrombosis Research, Vol. 15, pp. 617-629,
1979).
An another excellent point of FXa inhibitors is a
great difference between an effective dose in a thrombosis
model and a dose elongating bleeding time in an
experimental hemorrhagic model. From this experimental
result, FXa inhibitors are considered to be anticoagulants
having low risk of hemorrhage.
Various compounds have been reported as FXa
inhibitors. It is known that antithrombin III and
antithrombin III dependent pentasacchrides can generally
not inhibit prothrombinase complexes which play a
practical role in the thrombus formation in a living body
(Thrombosis Research, Vol. 68, pp. 507-512, 1992; Journal
of Clinical Investigation, Vol. 71, pp. 1383-1389, 1983;
Mebio, Vol. 14, the August number, pp. 92-97) . In addition,
they do not exhibit effectiveness by oral administration.
Tick anticoagulant peptide (TAP) (Science, Vol. 248, pp.
593-596, 1990) and antistasin (AST) (Journal of Biological
Chemistry, Vol. 263, pp. 10162-10167, 1988) isolated from
mites or leeches, which are bloodsuckers, also inhibit Fxa
and exhibit anti-thrombotic effects against venous
thrombosis and arterial thrombosis. However, these
compounds are high-molecular weight peptides and
unavailable in oral administration. As described above,
development of antithrombin III independent low-molecular
weight FXa inhibitors which directly inhibit coagulation
factors has been conducted.
It is therefore an object of the present invention
to provide a novel compound which has a potent FXainhibiting
effect and exhibits an anti-thrombotic effect
quickly, sufficiently and persistently by oral
administration.
DISCLOSURE OF THE INVENTION
The present inventors have investigated synthesis
and pharmacological effects of novel FXa inhibitors. As a
result, diamine derivatives, salts thereof, and solvates
and N-oxides thereof, which exhibit potent FXa-inhibiting
effect and anticoagulant effect, have been found. It has
also been found that these compounds promptly,
persistently and potently inhibit FXa and exhibit potent
anticoagulant effect and anti-thrombotic effect by oral
administration, and are hence useful as prophylactics and
remedies for various diseases based on thromboembolism,
thus leading to completion of the present invention.

Among the compounds (1) according to the present
invention, a preparation process of compound (Ic)
containing heteroatom(s) in the group Q3 will hereinafter
be described in detail.
A compound represented by the general formula (Ic), a
salt thereof, a solvate thereof, or an N-oxide thereof can
be prepared in accordance with, for example, the following
process:
R" Q4-C02H \ A / Q'-CP-CO.H Hv H

or the like, which is derived from carboxylic acid (3),
may react with compound (2c), giving compound (4c). The
resultant compound (4c) may react with carboxylic acid (5)
under the same conditions, giving compound (Ic) according
to the present invention.
In the above reaction steps, reagents and conditions,
which are generally used in peptide synthesis, may be
applied. The mixed acid anhydride can be prepared by, for
example, reaction of a chloroformate such as ethyl
chloroformate or isobutyl chloroformate with carboxylic
acid (3) in the presence of a base. The acid halide can be
prepared by treating carboxylic acid (3) with an acid
halide such as thionyl chloride or oxalyl chloride. The
activated ester includes various kinds of esters. Such an
ester can be prepared by, for example, reaction of a
phenol such as p-nitrophenol, N-hydroxybenzotriazol, or Nhydroxysccinimide
with carboxylic acid (3) using a
condensing agent such as N,N'-dicyclohexylcarbodiimide
(DCC) or 1-ethyl-3 - (3-dimethylaminopropyl)carbodiimide
hydrochloride. The activated ester can also be prepared by

thus-obtained mixed acid anhydride, acid halide or
activated ester of carboxylic acid (3) may react with
compound (2c) at a temperature under cooling to a
temperature under heating in the presence of a proper base
in an inert solvent, giving compound (4c). Thus-obtained
compound (4c) may react with a mixed acid anhydride, acid
halide or activated ester of carboxylic acid (5) under the
same conditions, giving compound (Ic) according to the
present invention. The reagents and reaction conditions in
the reaction of compound (4C) with carboxylic acid (5) are
the same as those in the reaction of diamine (2c) with
carboxylic acid (3).
As specific examples of the base used in each of the
above step, may be mentioned carbonates of alkali metals
or alkaline earth metals, such as sodium carbonate and
potassium carbonate, alkali metal alkoxides such as sodium
ethoxide and potassium butoxide, alkali metal hydroxides
such as sodium hydroxide and potassium hydroxide, and
hydrides of alkali metals, such as sodium hydride and
potassium hydride; organic metal bases exemplified by

bases exemplified by dialkylaminolithium such as lithium
diisopropylamide; organic metal bases of bis(silyl)amine,

include alkyl halide type solvents such as methylene
chloride and chloroform, etheric solvents such as

In the above-described preparation steps, processes
such as attaching and leaving of a protecting group, and
conversion of a functional group can be suitably applied,
thereby preparing compound (Ic).
As the protecting group for amino group, it is only
necessary to use a protecting group, which is generally
used as a protecting group for amino group in syntheses of
organic compounds, particularly, peptide synthesis. As
examples thereof, may be mentioned alkoxycarbonyl groups
such as tert-butoxycarbonyl, methoxycarbonyl and
ethoxycarbonyl groups, arylmethoxycarbonyl groups such as
benzyloxycarbonyl, p-methoxybenzyloxycarbonyl and p- or onitrobenzyloxycarbonyl
group, arylmethyl groups such as
benzyl, 4-methoxybenzyl and triphenylmethyl groups,

groups such as a benzoyl group, and arylsulfonyl groups
such as 2,4-dinitrobenzenesulfonyl and o-nitrobenzenesulfonyl

group such as a benzyl group. The attaching and leaving of
the protecting group may be conducted in accordance with a
method known per se in the art.
Compound (Ic) according to the present invention can
be converted into various derivatives by converting its
functional group. For example, a compound in which A
is a nitrogen atom having no substituent can be
converted into an amide compound by acylation using a
mixed acid anhydride, acid halide, activated ester or the

wherein Q1, Q2, Q4, R3, R4, A, m and n have the same
meanings as defined above, T1 represents a carbonyl group,
and R51 and R61 represent protecting groups for amino
group.
Compound (21) can be prepared by removing the
protecting group R61 of compound (19) obtained by
protecting the amino groups of compound (2c). No
particular limitation is imposed on the protecting groups
for amino acid illustrated as R51 and R61 so far as they are
groups generally used in protection of the amino group.
However, as typical examples thereof, may be mentioned the
protecting groups for amino group described in Preparation
Process 7. In this case, R51 and R61 are required to be
protecting groups capable of leaving by different methods
or conditions from each other. As typical examples thereof,
may be mentioned a combination that R51 is a tert-
butoxycarbonyl group, and R61 is a benzyloxycarbonyl group.
These protecting groups may be chosen for use according to
the nature and the like of the compound of which amino
groups are to be protected. Upon leaving such a protecting
group, reagents and conditions may be employed according
to the protecting group.
Compound (21) can also be prepared by converting the
hydroxyl group in aminoalcohol derivative (20) into an
amino group. As an example of the preparation of
aminoalcohol derivative (20), is known conversion of
methionine into 3-hydroxy-4-aminothiopyrane-1,1-dioxide
(Tetrahedron Lett., Vol. 37, p. 7457, 1996) or the like.

aminoalcohol derivative (20) into an amino group, may be
mentioned a process in which aminoalcohol derivative (20)
may react with methanesulfonyl chloride, p-toluenesulfonyl
chloride, trifluorome?thanesulfonic anhydride or the like,
the resultant product may then react with ammonia, a
primary arylalkylamine such as benzylamine, pmethoxybenzylamine
or 2,4-dimethoxybenzylamine, a
secondary arylalkylamine such as dibenzylamine, or a
hydroxylamine such as N-benzylhydroxylamine or N,Odibenzylhydroxylamine,
and benzyl group or the like is
then removed as needed, thereby preparing diamine (21).
Aminoalcohol derivative (20) can also be converted into
diamine (21) by reacting it with phthalimide or
succinirnide in accordance with the reaction with
triphenylphosphine and ethyl azodicarboxylate (Mukaiyama
method) or the like, and then treating the reaction
product with hydrazine, N-methylhydrazine or the like.
When A in the formula is S02, and n is 0, diamine (21) can
be prepared by adding ammonia, a primary arylalkylamine
such as ammonia, benzylamine, p-methoxybenzylamine or 2,4-
dimethoxybenzylamine, a secondary arylalkylamine such as
dibenzylamine, or a hydroxylamine such as Nbenzylhydroxylamine
or N,O-dibenzylhydroxylamine to an
a, (3-unsaturated cyclic sulfone formed by reacting

p-toluenesulfonyl chloride, trifluoromethanesulfonic
anhydride or the like and then treating the reaction
product with a proper base or directly reacting
aminoalcohol derivative (20) with triphenylphosphine and
ethyl azodicarboxylate, and removing the benzyl group or
the like as needed.
The resultant diamine (21) may react with carboxylic
acid (3), giving compound (22) . The protecting group R51
is successively removed, giving compound (4c). Compound
(4c) may react with carboxylic acid (5), giving compound
(Ic) according to the present invention. The reagents and

argon atmosphere, and the solution was cooled to -78°C, to
which n-butyllithium (1.60N hexane solution, 385 |jl) was
added dropwise. After the reaction mixture was stirred for
10 minutes at -78°C, and carbon dioxide was blown into the
reaction mixture for 20 minutes, it was warmed to room
temperature. After the reaction mixture was concentrated
under reduced pressure, the residue was dissolved in N,Ndimethylformamide
(10 ml). To the solution, were added the
compound (184 mg) obtained in Referential Example 71 , 1-
hydroxybenzotriazole monohydrate (76 mg) and l-(3-
dimethylaminopropy1)-3-ethylcarbodiimide hydrochloride
(215 mg) . The resultant mixture was stirred for 3 days.
The reaction mixture was concentrated, and methylene
chloride and a saturated aqueous solution of sodium
hydrogencarbonate were added to the residue to separate an
organic layer. The organic layer was dried over anhydrous
sodium sulfate, and the solvent was then distilled off
under reduced pressure. The resultant residue was purified
by column chromatography on silica gel (methanol:methylene
chloride = 3:97). After an ethanol solution (5 ml) of
hydrochloric acid was added to the thus-obtained product,
the mixture was stirred at room temperature for 1 hour,
and the reaction mixture was concentrated. Ethyl acetate
was added to the residue to solidify it. The resultant
powder was collected by filtration to obtain the title

The compound (301.8 ing) obtained in Example 141 was
dissolved in tetrahydrofuran (10 ml), and a IN aqueous
solution (0.53 ml) of sodium hydroxide was added to stir
the mixture at room temperature for 18 hours. Water was
added to the reaction mixture to conduct extraction with
methylene chloride. The resultant organic layer was
successively washed with water and saturated aqueous
solution of sodium chloride and dried over anhydrous
sodium sulfate. The solvent was distilled off under
reduced pressure, the residue was purified by column
chromatography on silica gel (methylene chloride:methanol
= 20:1 - 10:1), and the solvent was distilled off under
reduced pressure. The thus-obtained purified product was
dissolved in ethanol (3 ml) and methylene chloride (2 ml),
and a IN ethanol solution of hydrochloric acid to stir the
mixture for 30 minutes. The solvent was distilled off
under reduced pressure, and the residue was solidified
with diethyl ether to obtain the title compound (195 mg).

Determination of anti-FXa activity in rat plasma after
oral administration:
(A) Administration and blood collection:
A drug solution (1 mg/ml) obtained by dissolving or
suspending a test compound (10 mg) in 0.5% methyl
cellulose (MC) was orally administered to rats (10 ml/kg) .
After 0.5, 1, 2 and 4 hours from the drug administration,
861
the blood (0.5 ml) was collected through the jugular vein
using a syringe which is containing a 3.13% (w/v) aqueous
solution (50 pi) of trisodium citrate dihydrate (amount of
blood collected: 0.45 ml). For rats of a control group,
the same blood collection was conducted after a 0.5% MC
solution was administered. Each blood sample was
centrifuged at 1500 x g for 10 minutes at 4°C to separate
plasma, and the plasma was preserved at -40°C until it was
used in the following determination of anti-FXa activity
in plasma.
(B) Determination of FXa-inhibiting activity in plasma:
In the determination of anti-FXa activity in plasma,
S-2222 was used as a substrate. Tris buffer (100 mM Tris,
200 mM potassium chloride, 0.2% BSA, pH 7.4) (5456 ul),
human FXa (2.5 U/ml, 44 ul) and water (550 ul) were mixed.
The resultant human FXa solution was used in the following
test.
Rat plasma (5 ul) obtained in accordance with the
procedure (A) described above was put in wells of a 96-
well microplate, and the above-described human FXa
solution (55 ul) and a 750 uM aqueous solution (40 ul) of
S-2222 were sequentially added. Immediately after that,
absorbance at 405 nm was measured at room temperature by
means of a spectrophotometer SPECTRAmax 340 or 190
(Molecular Devices Co., U.S.A.), thereby determining a
rate of reaction (AOD/min).
The anti-FXa activity, i.e., percent inhibition (%)
was calculated in accordance with the following equation:
Percent inhibition (%) =
[1 - (AOD/min of sample) + (average value of AOD/min of
the control group)] x 100
(Result)
The compounds described in Examples 63, 191, 192,
194 and 204 exhibited a potent FXa-inhibiting activity of
62 to 96% at an oral dose of 10 mg/kg.
