Description

AMINOHETEROCICLIC DERIVATIVES AS ANTITROMBOTIC OR ANTICOAGULANT AGENTS DESCRIPTION OF THE INVENTION The invention relates to a group of aminoheterocyclic derivatives or their pharmaceutically acceptable salts, which possess antithrombotic and anticoagulant properties and are therefore useful in methods of treatment of the human or animal body. The invention also relates to processes for the preparation of aminoheterocyclic derivatives, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments for use in the production of an antithrombotic or anticoagulant effect. The antithrombotic and anticoagulant effect, produced by the compounds of the invention, is believed to be attributable to their strong inhibitory effect against the activated coagulation protease known as Factor Xa. Factor Xa is one of a cascade of proteases involved in the complex process of blood coagulation. The protease known as thrombin is the final protease in the cascade and Factor Xa is the preceding protease, which unfolds prothrombin to generate thrombin.
Certain compounds that possess Factor Xa inhibitory properties are known and the field has been reviewed by R.B. Wallis, Current Opinion in Therapeutic Patents, 1993, 1173-1179. Thus, it is known that two proteins, one known as antistatin and the other known as thickening anticoagulant protein (TAP) are specific Factor Xa inhibitors, which have antithrombotic properties in several animal models of thrombotic disease. It is also known that certain non-peptidic compounds possess inhibitory properties of Factor Xa. Of the low molecular weight inhibitors mentioned in the review by R.B. Wallis, all have a strongly basic group such as a group of idinophenyl or amidinonaphthyl. It is the object of the present invention to provide a new class of agents, which lacks the amidino group that was previously believed to be an essential characteristic for a Factor Xa inhibitor. It has now been found that certain aminosubstituted heterocyclic derivatives have Factor Xa inhibitory activity. Many of the compounds of the present invention also have the advantage of being selective Factor Xa inhibitors, ie the above Factor Xa is strongly inhibited at concentrations of the test compound which do not inhibit or inhibit to a lesser extent the Thrombin enzyme, which is also a member of the enzymatic cascade of blood coagulation. The compounds of the present invention possess activity in the treatment or prevention of a variety of medical disorders, where anticoagulant therapy is indicated, for example in the treatment or prevention of thrombotic conditions such as coronary artery disease and cerebrovascular disease. Other examples of such medical disorders include various cardiovascular and cerebrovascular states such as myocardial infarction, formation of atherosclerotic plaques, venous or arterial thrombosis, coagulation syndromes, vascular injury including reocclusion and restenosis after angioplasty and coronary artery bypass surgery, thrombus formation after the application of operative techniques in blood vessels, the introduction of artificial heart valves or in the recirculation of blood, cerebral infarction, cerebral thrombosis, stroke, cerebral embolism, pulmonary embolism, ischemia and angina (including unstable angina) . The compounds of the invention are also useful as inhibitors of blood coagulation in an ex vivo situation such as, for example, storage of whole blood or other biological samples suspected of containing Factor Xa and in the coagulation of which is harmful.

A suitable value for A when it is alkylene of 1-4 is, for example, methylene, ethylene, trimethylene and tetramethylene. It should be understood that when M1 is a group of the formula NR2-L1-T1R3 The order of presentation of this group is important in terms of the group's orientation of union. In this way, it is the group NR2, which is linked to the heterocyclic group, for example, when G1 and G2 are each CH, the pyridyl group which bears the substituent R1. It should also be understood that within the group NR2 is the atom N, which binds to L1. Likewise, the group R2 is linked to the N atom and not to the L1 group. Similarly in the group T1R3 it is the group T1 which is linked to the group A of the formula I (or the group CO within the formula I when A is a direct link) and the group R3 is linked to the group T1 and not to group A of formula I. A similar convention applies to the union of groups M2 and M3 and to the union of groups T2, T3 and NR6 within M2 or M3. It should further be understood that when R4 is an alkylene group of C2_ such as ethylene and trimethylene which are attached to a methylene group which L2 which forms a 5- or 6-membered ring involves T2 and R4, a suitable ring formed when T2 is N is, for example, pyrrolidin-1,3-diyl, piperidin-1,3-diyl and piperidin-1,4-diyl and a suitable ring formed when T2 is CH is, for example, cyclopentan-1,3-diyl, cyclohexane-1,3-diyl and cyclohexane-1,4-diyl. Such ring systems are also suitable when, for example, R 5 is attached to the methylene group within L 2. Ring systems such as pyrrolidin-1,3-diyl, pipéridin-1,3-diyl and piperidin-1,4-diyl are also suitable when R6 is attached to a methylene within L3. To avoid doubt it is established that a suitable heterocyclic group in a substituent, which may be present within M2 and M3 includes, for example, pyrrolidin-1-yl, piperidino, morpholino, piperazin-1-yl and 4-alkyl Cj ^ -piperazin-1-yl either directly attached or linked via a linking group, for example, as in pyrrolidin-1-ylcarbonyl-C 1-4 alkyl such as 2- (pyrrolidin-1-ylcarbonyl) ethyl . A suitable value for X when it is an N-alkylcarbonylamino group of C ^ _4 is, for example, N-methylcarbonyl-amino or N-ethylcarbonylamino; when it is alkylmethylene of C-, 4 is, for example, ethane-1,1-diyl or propane-1,1-diyl; and when it is di-C1-4 alkyl ethylene is, for example, propan-2,2-diyl. It should also be understood that when X is a carbonyloxy, carbonylamino or N-alkylcarbonylamino group of C-, 4, it is the carbonyl group within which it is attached to M3, Also, when X is a sulfonylamino group is the sulfonyl group within which is bound to M3 while, when X is an aminosulfonyl group, the sulfonyl group within is linked to Q. A suitable value for Q when it is naphthyl is, for example, 1-naphthyl or 2-naphthyl; when it is phenyl-C 4 alkyl is, for example, benzyl, phenethyl and 3-phenylpropyl, when it is phenyl-C 2-4 alkenyl is, for example, styryl, cinnamyl or 3-phenylprop-2-enyl; when it is phenyl-alkynyl of c2-4 is By eJemPl 2-phenylethynyl, 3-phenylprop-2-ynyl and 3-phenylprop-1-ynyl; and when it is C5_7 cycloalkyl it is, for example, cyclopentyl, cyclohexyl and cycloheptyl. A suitable value for Q when it is a heterocyclic portion containing up to 4 heteroatoms selected from the group consisting of nitrogen, oxygen and sulfur is, for example, a 5- or 6-membered heterocyclic moiety which is a single ring or is fused to one or two benzo rings such as furyl, benzofuranyl, tetrahydrofuryl, chromanyl, thienyl, benzothienyl, pyridyl, piperidinyl, quinolyl, 1, 2, 3, 4-tetrahydroquinolinyl, isoquinolyl, 1, 2, 3,4-tetrahydroisoquinolinyl, pyrazinyl, piperazinyl, pyrimidinyl, pyridazinyl, quinoxalinyl, quinazolinyl, cinolinyl, pyrrolyl, pyrrolidinyl, indolyl, indolinyl, imidazolyl, benzimidazolyl, pyrazolyl, indazolyl, oxazolyl, benzoxazolyl, isoxazolyl, thiazolyl, benzothiazolyl, isothiazolyl, morpholinyl, 4H-1,4-benzoxazinyl, 4H- 1, 4-benzothiazinyl, 1,2,3-triazolyl, 1,4-triazolyl, oxadiazolyl, furazanyl, thiadiazolyl, tetrazolyl, dibenzofuranyl and dibenzothienyl, which may be linked through any available position that includes, by an appropriate group X such as, for example, carbonyl and methylene, through any available nitrogen and which can be carried up to three substituents including a substituent on any available nitrogen atom. Suitable values for the substituents which may be present within Q include, for example: for C 1-4 alkoxycarbonyl: methoxycarbonyl, ethoxycarbonyl and tert-butoxycarbonyl; for C 1-4 alkyl: methyl, ethyl, propyl and isopropyl; for C ^ _4 alkoxy: methoxy, ethoxy, propoxy and isopropoxy, - for N-alkylcarbamoyl of C1- ^: -methylcarbamoyl and N-ethylcarbamoyl; for N, N-di-alkylcarbamsyl of C 1-4: N, N-dimethyl-carbamoyl and N, N-diethylcarbamoyl; for C1-4 alkylamino: methylamino, ethylamino and propylamino; for di-alkylamino of C -] __ 4: dimethylamino, N-ethyl-N-methylamino and diethylamino; for C2_4 alkanoylamino: acetamido, propionamido and butyramido; for C2_4 alkanoyl: acetyl, propionyl and butyryl; for c2-4 alkanoimidoyl: acetimidoyl and propionimidoyl; and for alkanehydroxyperoxy: acetohydroximoyl and propionohydroximoyl. A suitable value for the heteroaryl substituent or the heteroaryl group in a heteroaryl-containing substituent, which comprises a 5- or 6-membered monocyclic heteroaryl ring containing up to 3 heteroatoms selected from the group consisting of oxygen, nitrogen and sulfur is, for example , furyl, thienyl, pyridyl, pyrazinyl, pyrimidinyl, pyridazinyl, pyrrolyl, pyrazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, 1,2,3-triazolyl, 1,2,4-triazolyl, oxadiazolyl, furazanyl and thiadiazolyl, which can be be united through any available position that includes through any available nitrogen atom.
