Claim:
A diamine of general formula (I): wherein: A is A1 or A2 having the following general formula: wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11 and R12 are independently selected from the group consisting of hydrogen, halogen, alkyl, cycloalkyl, CN, NO 2 , hydroxyl, aryl, aralkyl, alkoxy, aryloxy, amino, alkylamino, dialkylamino, cycloalkylamino, arylamino, arylalkylamino, diarylamino, diarylalkylamino, trihaloalkyl and trihaloalkoxy, provided that when A is A1 at least one of the radicals R1, R2, R3, R4 or R5 is hydrogen when the other four radicals are not hydrogen, B is B1 or B2 having the following general formula: wherein R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R23 and R24, are independently selected from the group consisting of hydrogen, halogen, alkyl, cycloalkyl, CN, NO 2 , hydroxyl, aryl, aralkyl, alkoxy, aryloxy, amino, alkylamino, dialkylamino, cycloalkylamino, arylamino, arylalkylamino, diarylamino, diarylalkylamino, trihaloalkyl and trihaloalkoxy, provided that when B is B1, at least one of the radicals R13, R14, R15, R16 or R17 is hydrogen when the other four radicals are not hydrogen, X is SO 2 , CH 2 , C═O or COO, is CH(R25)—CH(R26) or CH(R27)═CH(R28), wherein R25, R26, R27 and R28 are independently selected from the group consisting of hydrogen, halogen, alkyl, cycloalkyl, CN, NO 2 , hydroxyl, aryl, aralkyl, alkoxy, aryloxy, amino, alkylamino, dialkylamino, cycloalkylamino, arylamino, arylalkylamino, diarylamino, diarylalkylamino, trihaloalkyl and trihaloalkoxy; and salts thereof optionally further comprising a pharmaceutically acceptable acid, wherein the diamine is a racemic mixture of isomers or a purified isomer.
