Nakiterpiosin and nakiterpiosinone are two related C-nor-D-homosteroids isolated from the sponge Terpios hoshinota that show promise as anticancer agents. We have previously described the asymmetric synthesis and revision of the relative configuration of nakiterpiosin. We now provide detailed information on the stereochemical analysis that supports our structure revision and the synthesis of the originally proposed and revised nakiterpiosin. In addition, we herein describe a refined approach for the synthesis of nakiterpiosin, the first synthesis of nakiterpiosinone, and preliminary mechanistic studies of nakiterpiosin's action in mammalian cells. Cells treated with nakiterpiosin exhibit compromised formation of the primary cilium, an organelle that functions as an assembly point for components of the Hedgehog signal transduction pathway. We provide evidence that the biological effects exhibited by nakiterpiosin are mechanistically distinct from those of well-established antimitotic agents such as taxol. Nakiterpiosin may be useful as an anticancer agent in those tumors resistant to existing antimitotic agents and those dependent on Hedgehog pathway responses for growth.

Nakiterpiosin 和 Nakiterpiosinone 的化学和生物学研究

Nakiterpiosin 和 nakiterpiosinone 是从海绵 Terpios hoshinota 中分离出来的两种相关的 C-nor-D-同类固醇,它们显示出作为抗癌剂的前景。我们之前已经描述了 nakiterpiosin 的相对构型的不对称合成和修订。我们现在提供有关立体化学分析的详细信息,以支持我们的结构修订以及最初提出和修订的纳基特皮奥斯的合成。此外,我们在本文中描述了合成 nakiterpiosin 的精细方法、首次合成 nakiterpiosinone 以及 nakiterpiosin 在哺乳动物细胞中的作用的初步机制研究。用 nakiterpiosin 处理的细胞表现出初级纤毛的形成受损,初级纤毛是一种细胞器,用作 Hedgehog 信号转导途径的组件的组装点。我们提供的证据表明,nakiterpiosin 表现出的生物效应在机制上不同于成熟的抗有丝分裂剂(如紫杉醇)。Nakiterpiosin 可用作对现有抗有丝分裂剂有抗性的肿瘤和依赖 Hedgehog 通路响应生长的肿瘤中的抗癌剂。
