    • The invention relates to epothilone analog represented by the 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 the 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.
    • 本发明涉及由式I表示的埃坡霉素类似物,其中(i)R2不存在或氧; “a”可以是单键或双键; “b”可以是缺席或单一债券; 和“c”可以不存在或单键,条件是如果R2是氧,则“b”和“c”都是单键,“a”是单键; 如果R2不存在,则“b”和“c”不存在,“a”是双键; 如果“a”是双键,那么R2,“b”和“c”不存在; R3是选自氢的基团; 低级烷基 -CH-CH 2; -C≡CH; -CH2F; -CH2Cl; -CH 2 -OH; -CH 2 -O-(C 1 -C 6 - 烷基); 和-CH 2 -S-(C 1 -C 6 - 烷基); R 4和R 5独立地选自氢,甲基或保护基; R1如本说明书中所定义,或其中存在成盐基团的式I化合物的盐。 本发明的另一方面涉及埃坡霉素E的合成。这些化合物尤其具有微管解聚抑制活性, 对增殖性疾病有用。
