  Creation of Readily Accessible and Orally Active Analogue of Cortistatin A

  摘要：

  Syntheses of structurally simplified analogues of cortistatin A (1), a novel antiangiogenic steroidal alkaloid from Indonesian marine sponge, and their biological activities were investigated. The analogues were designed by considering the 3-D structure of 1. Compound 30, in which the isoquinoline moiety was appended to the planar tetracyclic core structure, showed potent antiproliferative activity against human umbilical vein endothelial cells (HUVECs) together with high selectivity and also showed in vivo antiangiogenic activity and significant antitumor effect by oral administration.

  An improved method for synthesizing structurally simplified analogs of cortistatin A (1), a novel anti-angiogenic steroidal alkaloid from a marine sponge, was developed. In contrast to previous methods, step- and redox-economical synthesis was achieved using a known α-bromoketone as the starting material. The structure-activity relationship study revealed that the isoquinoline portion was strictly recognized

  开发了一种改进的方法，用于从海洋海绵中合成皮质抑素A（1）（一种新型的抗血管生成类固醇生物碱）的结构简化类似物。与以前的方法相比，使用已知的α-溴代酮作为起始原料，可以实现分步和氧化还原经济的合成。结构-活性关系研究表明，异喹啉部分被目标分子严格识别。出人意料的是，在A环结构上引入乙酰胺部分极大地增强了对内皮细胞的选择性抗增殖活性。这种新方法可以轻松地用于克级合成，并使我们能够制备各种类似物，这些类似物侧重于侧链和A环结构的参与。
