metabolites. The structures of eight of these metabolites have been now confirmed by synthesis and their biological properties have been reported. Eaton’s reagent was utilized as a convenient condensing agent, allowing, among others, a simple multigram scale preparation of phenstatin. Synthesized metabolites and related compounds were evaluated for their antiproliferative activity in the NCI-60 cancer cell
以前对非那他汀与大鼠和人类微粒体组分温育的研究表明形成了九种主要代谢产物。现在已经通过合成确认了其中8种代谢物的结构,并报道了它们的
生物学特性。伊顿的试剂被用作便利的
缩合剂,除其他外,还可以简单地制得数克规模的芬他汀。评价了合成代谢产物和相关化合物在NCI-60癌
细胞系中的抗增殖活性,以及它们对微管组装的影响。代谢物23(2'-甲氧吩他汀)表现出最有效的体外细胞毒性活性:抑制K-562,NCI-H322M,NCI-H522,KM12,M14,
MDA-MB-435,NCI / ADR-RES,和带有GI的HS 578T
细胞系50个值<10 nM。它也显示出比亲本芬他汀(3)更显着的微管蛋白聚合抑制活性(IC 50 = 3.2μM对15.0μM ),并在鼠白血病
DA1-3b细胞中诱导G2 / M阻滞。对这种活性代谢产物的鉴定导致了具有强大的体外细胞毒性和抑制微管组装的类似物的设计和合成。
