The chloro-, bromo-, and iodo-derivatives 2-4 of the antimitotic drug cryptophycin 1 were synthesized by opening the epoxide ring. The biological activities of the compounds were tested in an in vitro microtubule assembly and a cell proliferation assay. The chloro-derivative 2 showed lower activity in the tubulin assay compared to 3 and 4, but they all showed similar inhibition in the proliferation assay.
抗有丝分裂药物隐藻素1的氯代、溴代和碘代衍生物2 - 4通过环氧环开环反应合成。这些化合物的生物活性在体外微管组装和细胞增殖试验中进行了测试。氯代衍生物2在微管蛋白试验中的活性低于3和4，但它们在增殖试验中均表现出相似的抑制作用。
