Abstract

(R,S)-1 is a potent antimitotic compound. (R)-1·HCl and (S)-1·HCl were synthesized from (R)- and (S)-3-methyladipic acid. Both enantiomers were potent inhibitors of cell proliferation and caused cellular microtubule loss and mitotic arrest. They inhibited purified tubulin assembly and the binding of [(3)H]colchicine to tubulin, with (S)-1 being about twice as potent. Cytotoxicity against 60 tumor cell lines, however, indicated that the (S)-isomer was 10- to 88-fold more potent than the (R)-isomer.

摘要

(R,S)-1 是一种有效的抗有丝分裂化合物。(R)-1·HCl 和(S)-1·HCl 是由(R)-和(S)-3-甲基己二酸合成的。两种对映异构体都是有效的细胞增殖抑制剂,可导致细胞微管丢失和有丝分裂阻滞。它们抑制纯化微管的组装和 [(3)H]秋水仙碱与微管的结合,(S)-1 的活性约为(R)-1 的两倍。然而,对 60 种肿瘤细胞系的细胞毒性表明,(S)-异构体的活性比(R)-异构体强 10 到 88 倍。
