[structure: see text] Effective, scalable total syntheses and biological evaluation of six phorboxazole A analogues (1-6) have been achieved. Importantly, the C(45-46)-saturated, C(45-46)-alkenyl, and the C(45-46)-E-chloroalkenyl congeners (4, 5, and 6, respectively) reveal low nanomolar tumor cell growth inhibitory activity (GI50's) similar to or, in some cell lines, greater than that of the phorboxazoles
[结构:见正文]已经实现了六种邻苯二唑A类似物(1-6)的有效,可扩展的总合成和生物学评估。重要的是,饱和的C(45-46),C(45-46)-烯基和C(45-46)-E-氯代烯基同类物(分别为4、5和6)显示出低的纳摩尔肿瘤细胞生长在多种人类癌细胞系中,其抑制活性(GI50)类似于或在某些细胞系中均比邻苯二恶唑更高。
