Embelin is a natural product, inhibitor of XIAP (X-chromosome-linked Inhibitor of APoptosis) with strong proapoptotic properties on cancer cells. In order to clarify the role of two OH groups on benzoquinone core, we have prepared by hemisynthesis close analogs of embelin, where these OH groups have been replaced in a systematic manner by OMe and OAc groups. Proapoptotic activities of six embelin derivatives
Embelin是天然产物,XIAP(X染色体连锁的APoptosis抑制剂)的抑制剂,对癌细胞具有强的促凋亡特性。为了澄清苯醌核心上的两个OH基团的作用,我们通过半合成制备了Embelin的紧密类似物,其中这些OH基团已被OMe和OAc基团系统地取代。已经研究了六种栓塞蛋白衍生物作为单药或与TRAIL组合时的促凋亡活性,并已通过Surface Plasmon Biacore评估了它们与XIAP相互作用的能力。我们的结果表明,这些新的Embelin类似物对选定的癌细胞具有良好的促凋亡特性,通常高于天然产物本身。此外,该活性不是由XIAP直接介导的。
