EPOTHILON DERIVATIVES, METHOD FOR THE PRODUCTION AND THE USETHEREOF AS PHARMACEUTICALS

摘要

The invention relates to the novel epothilon derivatives of general formula (I) wherein R4 is hydrogen, C1-C10 alkyl, aryl, C7-C20 aralkyl, R5 is hydrogen, C1-C10 alkyl, aryl, C7-C20 aralkyl, R6, R7 are each a hydrogen ato m, or together an additional bond or an oxygen atom, R8 is a methyl group or hydrogen, and simultaneously R1a and R1b together represent a trimethylene group and X is a 2-pyridyl, 2-methyl-4-thiazolyl or 2-methyl-4-oxazolyl residue or simultaneously R1a and R1b together represent a trimethylene grou p, R2 is a methyl, ethyl or propyl group and X is a 2-pyridyl, 2-methyl-4- thiazolyl or 2-methyl-4-oxazolyl residue or simultaneously R1a and R1b each represents a methyl group, R2 is a methyl, ethyl or propyl residue and X is a 2-pyridyl, 2-methyl-4-thiazolyl or 2-methyl-4-oxazolyl residue, wherein the nitrogen and/or sulfur atom in X can be present in oxidized form and, if R2 and R8 each means a methyl residue, X can only be a 2-pyridyl residue which is optionally oxidized at the nitrogen atom, including all possible stereoisome rs and their mixtures. The novel compounds are useful for producing medicaments .
