New phosphatidyl alkanoic acid derivatives

摘要

Phosphatidyl alkanoic acids of formula (I) and their tautomers, optical isomers and salts are new:"R<1> in a group -(CH2)e-Cycl corresponds to a straight-chain or branched, saturated or unsaturated alkylene chain with e equal to a whole number between 4-16, where one of the carbon atoms starting from position 3 can be replaced by a heteroatom "oxygen, nitrogen or sulphur)"; R<2> = optionally saturated by 8-12C alkyl; X and Y = bonds, O, S, OCO, COO, CONH, NHCO, SO or SO2; Cycl = a 5-7C cycloalkyl or phenyl group in which one C atom may be replaced by N and which are optionally substituted by 1-6C alkyl, 1-6C alkoxy, 1-6C alkylthio or halogen; m = 0-3; "with the proviso that R<1> can be the same as R<2> when R<2> simultaneously has the same meaning as R<1>".
