A rapid domino π‐cationic arylation of aromaticcarboxylicacids, mediated by Eaton’s reagent, has been developed for the synthesis of Iasi‐red polymethoxylatedpolycyclicaromatichydrocarbons (PAHs). This route is currently the easiest method to obtain such popular PAH compounds, which bear in addition numerous methoxy groups. The domino process was generalized, the structure of the obtained red
由伊顿试剂介导的芳香族羧酸的快速多米诺π-阳离子芳基化反应已被开发用于合成Iasi-red聚甲氧基化多环芳香烃(PAHs)。目前,该路线是获得此类流行的PAH化合物的最简便方法,该化合物还带有许多甲氧基。对多米诺骨化过程进行了概括,阐明了所得红色产物的结构及其形成机理,并确定了它们的一些光物理性质。在一组NCI-60人类癌细胞系上测试了新合成的聚甲氧基PAHs与微管蛋白聚合的相互作用以及细胞毒性。有趣的是,这些红宝石衍生物之一在体外表现出显着的细胞毒性,包括抑制白血病,结肠癌,黑色素瘤,中枢神经系统,在低纳摩尔范围内(GI 50 <10 n M)有50个值。
Synthesis and biological evaluation of phenstatin metabolites
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
