摘要: The invention relates to epothilone analog represented by formula (I) wherein (i) R2 is absent or oxygen; 'a' can be either a single or double bond; 'b' can be either absent or a single bond; and 'c' can be either absent or a single bond, with the proviso that if R2 is oxygen then 'b' and 'c' are both a single bond and 'a' is a single bond; if R2 is absent then 'b' and 'c' are absent and 'a' is a double bond; and if 'a' is a double bond, then R2, 'b' and 'c' are absent; R3 is a radical selected from the group consisting of hydrogen; lower alkyl; -CH=CH2; -C CH; -CH2F; -CH2Cl; -CH2-OH; -CH2-O-(C1-C6-alkyl); and -CH2-S-(C1-C6-alkyl); R4 and R5 are independently selected from hydrogen, methyl or a protecting group; and R1 is as defined in the specification, or a salt of a compound of formula (I) where a salt-forming group is present. A further aspect of the invention is related to the synthesis of epothilone E. These compounds have inter alia microtubuli depolymerisation inhibiting activity and are e.g. useful against proliferative diseases.

摘要: Epothilone A, epothilone B, analogs of epothilone and libraries of epothilone analogs are synthesized. Epothilone A and B are known anticancers agents that derive their anticancer activity by the prevention of mitosis through the induction and stabilization of microtubulin assembly. The analogs of epothilone are novel. Several of the analogs are demonstrated to have a superior cytotoxic activity as compared to epothilone A or epothilone B as demonstrated by their enhanced ability to induce the polymerization and stabilization of microtubules.
