whose coupling with a lipophilic segment under Wittig conditions, followed by deprotection and a THF core construction, completed the convergent synthesis of 2-epimer of 1. The final anhydrophytosphingosine 4.HCl was screened for its antiproliferative/cytotoxic activity employing multiple human cancer cell lines. In vitro evaluation revealed that 2-epi-jaspine B exhibited significant antitumour growth
已经开发出一种直接获得2-epi-jaspine B(4.HCl)的方法。该方法的关键是使用Overman重排来安装带有氮原子的立体中心。随后的立体选择性转化的合理执行提供了功能化的支架38,其在维蒂希条件下与亲脂性片段偶联,然后脱保护并用THF核构建,完成了1的2-Epimer的聚合合成。最终的脱
水植物鞘氨醇4.HCl为使用多种人类癌
细胞系筛选其抗增殖/细胞毒性活性。体外评估表明,2-表-J-山脑B对所有用过的细胞均表现出显着的抗肿瘤生长抑制活性。
