Abstract
1392272 Rifamycin derivatives GRUPPO LEPETIT SpA 29 March 1973 [31 May 1972] 15l91/ Heading C2C Derivatives of rifamycin SV having the general formula and 16, 17, 18, 19, 28 and 29 hexahydro and 25-desacetyl derivatives thereof wherein the symbol Rifa represents the rifamycin radical of formula and A represents (1) a direct bond connecting the two nitrogen atoms ; (2) a group wherein y is -CO-, -CNH-, -CS-, -SO 2 -, a divalent, aliphatic, cycloaliphatic, aromatic, araliphatic, or heterocyclic radical; R 2 and R 3 indedendently represent hydrogen, alkyl or taken together represent an aliphatic divalent chain of 1-4 carbon atoms connecting the two terminal nitrogen atoms, or (3) a divalent group wherein X represents a direct bond between the two carbon atoms, a divalent aliphatic, cycloaliphatic, aromatic, or heterocyclic radical, R and R 1 may be independently hydrogen, alkyl, cycloalkyl, aryl, heterocyclic or taken together represent an aliphatic chain of 1 to 8 C atoms connecting the two terminal carbon atoms, may be prepared by reacting 3-formylrifamycin SV or its 25-desacetyl or 16, 17, 18, 19, 28 and 29 hexahydro derivative with a hydrazine compound of the formula H 2 N-A-NH 2 in an inert organic solvent at a temperature ranging from room temperature to the boiling temperature of the solvent. Compounds prepared include 3-formylrifamycin SV azine, 16, 17, 18, 19, 28, 29 - hexahydro - 3 - formylrifamycin SV azine and 1,4-piperazinylidene-bis-(3,3<SP>1</SP>-iminomethyl rifamycin SV). Pharmaceutical compositions having antibacterial and anti-tumour activity comprise the above derivatives of rifamycin SV and a pharmaceutically acceptable carrier.
