  Hemisynthetic Secofriedelane Triterpenes with Inhibitory Activity against the Growth of Human Tumor Cell Lines in Vitro

  摘要：

  Seco acids 7 and 9 and hydroxylated analogues 5 and 6 derived from friedelane triterpenes were synthesized stereoselectively in high yields. Compounds 5-9 were evaluated for their ability to inhibit in vitro the growth of three human tumor cell lines, MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer), and SF-268 (CNS cancer). Only compounds 7 and 9 were found to possess significant growth inhibitory effects, exhibiting GI(50) values that range from 24.6 to 32.8 muM and 10.9 to 17.6 muM, respectively.

  摘要：

• Basic Autoxidation of Friedelin

  日期：1987.6

  Base-catalyzed autoxidation of a triterpene ketone, friedelin, in the presence of potassium t-butoxide gave four products, and their structures and formation mechanism were investigated. The common intermediate to these compounds was suggested to be 4-hydroperoxyfriedelan-3-one, not friedelane-2,3-dione. 3-Oxafriedel-1-ene-2-carboxylic acid was a dehydration product of the main product, 2-hydroxy-

  在叔丁醇钾的存在下碱催化三萜酮弗里德林自氧化得到四种产物，并研究了它们的结构和形成机制。这些化合物的常见中间体被认为是 4-hydroperoxyfriedelan-3-one，而不是 Friedelane-2,3-dione。3-Oxafriedel-1-ene-2-羧酸是主要产物2-羟基-3-oxafriedelane-2-羧酸的脱水产物。
