IMIDAZOLE DERIVATIVES, THEIR PREPARATION AND THEIR USE AS S-ADENOSYLMETHIONINE DECARBOXYLASE (=SAMDC) INHIBITORS

摘要

Described are compounds of formula (I), wherein R1 is hydrogen or hydroxy; R2, R2' and R2" are each independently of the others hydrogen or a substituent other than hydrogen; either R3 is hydrogen or a substituent other than hydrogen and R4 is hydrogen or lower alkyl, or R3 and R4 together form a divalent radical of the formula -(CH2)n- wherein n is 2 or 3; R5 and R6 are each indenpendently of the other hydrogen, alkyl or aryl; and either R7 and R8 are each hydrogen, or R7 and R8 together form a bond; tautomers thereof, provided that at least one tautomerisable group is present; and salts thereof. The compounds inhibit the enzyme S-adenosylmethionine decarboxylase and are suitable, for example, for the treatment of tumors and protozoal infections.
