The antineoplastic constituents of Combretum caffrum (Eckl. and Zeyh) Kuntze (Combretaceae family), a species indigenous to South Africa, have been investigated. Subsequently we isolated a series of closely related bibenzyls, stilbenes, and phenanthrenes from C. caffrum. Some of the stilbenes proved to be potent antimitotic agents which inhibited both tubulin polymerization and the binding of colchicine
已经研究了南非原住民种Com囊(Eckl。和Zeyh)昆茨(Combretaceae家族)的抗肿瘤成分。随后,我们从C. caffrum中分离了一系列密切相关的联苄,苯乙烯和菲。已证明某些对苯二酚是有效的抗有丝分裂剂,可抑制微管蛋白聚合和秋水仙碱与微管蛋白的结合。Combretastatin A-4已被证明是该系列中最有效的癌细胞生长抑制剂。目前,这种顺式-二苯乙烯是秋水仙碱与微管蛋白结合的最有效抑制剂,并且是迄今为止描述的具有这种有效抗微管蛋白作用的最简单的天然产物。还发现Combretastatin A-4,A-5和A-6会抑制淋病奈瑟氏球菌的生长。康布雷他汀A-4(2a)的分离和合成细节,
