and a favorite hit for many naturally occurring molecules. While two of the most successful representative agents in clinical use, the taxanes and the vinca alkaloids, come from terrestrial sources, the sea has also proven to be a rich source of new tubulin-binding molecules. We describe herein the first isolation, structural elucidation and total synthesis of two totally new polyketides isolated from
微管仍然是最成功的抗癌药物靶点之一,也是许多天然分子的最爱。虽然临床使用的两种最成功的代表性药物紫杉烷和长春花生物碱来自陆地,但海洋也已被证明是新的微管蛋白结合分子的丰富来源。我们在此描述了从马达加斯加海绵 Lithoplocamia lithistoides 中分离出的两种全新聚酮化合物的首次分离、结构解析和全合成。PM050489 和 PM060184 在亚纳摩尔浓度的人肿瘤细胞系中均显示出抗有丝分裂特性,并对微管显示出独特的抑制机制。高效合成程序的开发解决了供应问题,并且随着药物开发,
