异马拉巴烷包括一大类海洋三萜类化合物,具有迷人的结构,已被证明是某些癌细胞系中选择性和有效的细胞凋亡诱导剂。在这篇文章中,我们描述了异马拉巴烷类 stelletin A、stellin E 和 Rhabdastrellic acid A 的成功全合成,以及开发获取这一独特家族中其他天然产物的一般策略。在这一努力中使用了高通量实验和计算化学方法。对 stelletin A 的初步构效关系研究揭示了异马拉巴烷的 trans-syn-trans 核心基序对其细胞毒活性至关重要。
Six alpha-pyrones, called gibepyrones A-F, were identified in three different culture media of G. fujikuroi (IMI 58289). Their structures were determined using both spectroscopic techniques and chemical synthesis. Their antimicrobial activity has been screened.

The isomalabaricanes comprise a large family of marine triterpenoids with fascinating structures that have been shown to be selective and potent apoptosis inducers in certain cancer cell lines. In this article, we describe the successful total syntheses of the isomalabaricanes stelletin A, stelletin E, and rhabdastrellic acid A, as well as the development of a general strategy to access other natural
