A series of novel 9-substituted camptothecins derived from 9-formylcamptothecin were synthesized. The aldehyde was obtained from 10-hydroxycamptothecin or, better, by total synthesis. The compounds showed antiproliferative activity higher than that of the reference compound topotecan. Modelling suggested the possibility of a favourable interaction of small and polar 9-substituents with the topoisomerase
合成了一系列衍生自9-甲酰基喜树碱的新型9-取代喜树碱。醛得自10-羟基喜树碱,或者更好的是通过全合成获得。该化合物显示出比参考化合物拓扑替康更高的抗增殖活性。建模表明,小而极性的9位取代基与拓扑异构酶I-DNA复合物之间可能存在有利的相互作用,这与这些衍生物相对于相应的7个取代的喜树碱具有更高的活性相一致。
