Abstract	4-[4-(2-pyrrolylcarbonyl)-l-piperazinyl]-3-trifluoroniethyl-benzoylguanidine hydrochloride 1

Full Text	New Benzoylguanidine Salt The invention relates to the hydrochloride of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethyl-benzoylguanidine, processes for preparing it and its use in preparing a pharmaceutical composition. Background to the invention A number of benzoylguanidine derivatives are known in the art. Thus, for example, International Patent Application WO 00/17176 discloses benzoylguanidine derivatives which are characterised by valuable pharmacological properties. These compounds are effective against arrhythmias which occur in hypoxia, for example. They may also be used for complaints connected with ischaemia (such as: cardiac, cerebral, gastrointestinal - such as mesenteric thrombosis/embolism -, pulmonary or renal ischaemia, ischaemia of the liver, ischaemia of the skeletal muscles). Corresponding indications include, for example, coronary heart disease, cardiac infarct, angina pectoris, stable angina pectoris, ventricular arrhythmia, subventricular arrhythmias, cardiac insufficiency - and also for assisting bypass operations, for assisting open heart surgery, for assisting operations which require an interruption to the blood supply to the heart and to assist in heart transplants - embolism in the pulmonary circulation, acute or chronic kidney failure, chronic renal insufficiency, cerebral infarct, reperfusion darpage in the restoration of blood supply to areas of the brain after the break-up of vascular occlusions and acute and chronic circulatory disorders of the brain. The abovementioned compounds may also be used in such cases in conjunction with thrombolytic agents such as t-PA, streptokinase and urokinase. During reperfusion of the ischaemic heart (e.g. after an attack of angina pectoris or a cardiac infarct) irreversible damage may occur to cardiomyocytes in the affected region. In such cases the compounds have a cardioprotective effect, inter alia. The category of ischaemia should also include the prevention of damage to transplants (e.g. as protection for the transplanted organ - such as for example liver, kidney, heart or lung - before, during and after implantation and during the storage of the transplant organs), which may occur in connection with transplantation. The compounds disclosed in WO 00/17176 are also pharmaceutical compositions with a protective effect in carrying out angioplastic surgical interventions on the heart and on peripheral blood vessels. In essential hypertension and diabetic nephropathy the cellular sodium-proton exchange is increased. The compounds are therefore suitable as inhibitors of this exchange for the preventive treatment of these diseases. The compounds are further characterised by a powerful inhibiting effect on the proliferation of cells. Therefore, the compounds are useful as medicaments in diseases where cell proliferation plays a primary or secondary part and may be used as agents against cancers, benign tumours or, for example, prostatic hypertrophy, atherosclerosis, organ hypertrophy and hyperplasia, fibrotic diseases and late complications of diabetes. The abovementioned pharmacologically valuable properties of the benzoylguanidine derivatives disclosed in the prior art are the main prerequisite for effective use of a compound as a pharmaceutical composition. However, an active substance has to satisfy still more requirements in order to be allowed to be used as a medicament. These parameters are largely connected to the physico-chemical nature of the active substance. Without being restricted thereto, examples of these parameters are the stability of effect of the starting substance under different ambient conditions, stability during the production of the pharmaceutical formulation and stability in the finished compositions of the medicamerft. The pharmaceutical active substance used to prepare the pharmaceutical compositions should therefore have high stability which must also be guaranteed even under different ambient conditions. This is absolutely necessary to prevent the use of pharmaceutical compositions which contain breakdown products of the active substance, for example, in addition to the active substance itself. In such a case the content of active substance present in pharmaceutical formulations may be lower than specified. The absorption of moisture reduces the content of pharmaceutical active substance because of the increase in weight due to the uptake of water. Pharmaceutical compositions with a tendency to absorb moisture have to be protected from moisture during storage, for example by the addition of suitable drying agents or by storing the pharmaceutical composition in an environment which is protected from damp. Moreover, the uptake of moisture may reduce the content of pharmaceutical active substance during manufacture if the pharmaceutical composition is exposed to the environment without any protection from moisture whatsoever. Preferably, therefore, a pharmaceutical active substance should be only slightly hygroscopic. As the crystal modification of an active substance can influence the activity of a pharmaceutical composition, it is necessary to clarify any existing polymorphism of an active substance present in crystalline form as much as possible. If there are different polymorphic modifications of an active substance, care must be taken to ensure that the crystalline modification of the substance does not change in the subsequent pharmaceutical preparation. Otherwise, this could have a detrimental effect on the reproducible activity of the medicament. In this context, active substances which are characterised by limited polymorphism are preferred. Another criterion which may be of exceptional importance in certain circumstances, depending on the choice of formulation or on the choice of the method of production of the formulation, is the solubility of the active substance. If for example pharmaceutical solutions are prepared (for example for infusions), it is essential that the active substance is sufficiently soluble in physiologically acceptable solvents. A sufficiently soluble active substance is also very important for pharmaceutical compositions administered orally. The underlying aim of the present invention is to prepare a pharmaceutical active substance which is not only characterised by a potent pharmacological activity but also satisfies as far as possible the physico-chemical requirements referred to above. Detailed description of the invention It has been found that the abovementioned aim is achieved by means of the compound 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethyl- benzoylguanidine-hydrochloride 1[ (Figure Removed) The compound of formula 1^ is not hygroscopic and dissolves readily in physiologically acceptable solvents. It is also characterised by a high degree of stability. The methanesulphonate of formula IT disclosed in WO 00/17176 (Figure Removed)nlike the compound of formula 1, does not meet the requirements set out hereinbefore, however. Accordingly, in one aspect the present invention relates to the compound of formula ^ as such. In another aspect the present invention relates to the compound of formula "\_ in the form of its hydrates, preferably in the form of its monohydrate or hemihydrate. In another aspect the present invention relates to the use of the compound of formula ^ as a medicament. The present invention further relates to the use of the compound of formula 1, optionally in the form of its hydrates, for preparing a pharmaceutical composition for treating diseases in which inhibitors of the cellular Na+/H+ exchange may develop a therapeutic benefit. The present invention further relates to the use of the compound of formula 1_to prepare a pharmaceutical composition for treating cardiovascular diseases. The present invention further relates to the use of the compound of formula 1_to prepare a pharmaceutical composition for treating arrhythmia such as occurs in hypoxia, for example.

The present invention further relates to the use of the compound of formula \ to prepare a pharmaceutical composition for treating diseases in which the use of cardioprotective active substances may be of therapeutic benefit. The present invention further relates to the use of the compound of formula \_ to prepare a pharmaceutical composition for treating cancers, benign tumours or, for example, prostatic hypertrophy, atherosclerosis, organ hypertrophy and hyperplasia, fibrotic diseases and late complications of diabetes. The compound of formula \ may be used as an aqueous injectable solution (e.g. for intravenous, intramuscular or subcutaneous administration), as a tablet, as a suppository, as an ointment, as a plaster for transdermal administration, as an aerosol for inhalation into the lungs or as a nasal spray.

For inhalation the single dose is between 0.05 and 20 mg, preferably between 0.2 and 5 mg. For parenteral injection the single dose is between 0.1 and 50 mg, preferably between 0.5 and 20 mg.
