This proposal focuses on the synthesis of antineoplastic agents. In the quassinoid area major emphasis will be placed on completing syntheses of quassimarin, bruceantin, and glaucarubinone. As a result of the lower toxicity in in vivo systems of 4beta-hydroxy withanolide E relative to cardenolides and bufadienolides, a synthetic program centered around 4beta-hydroxy withanolide E has been initiated in an effort to uncover an analog possessing a reasonable therapeutic index. Part III of this proposal focuses on a convergent total synthesis of the potent cytotoxic cyclodepsidpeptide, jaspamide. In addition a number of analogs will be prepared in order to examine the structural requirements for biological activity.

该建议的重点是合成的抗肿瘤剂。 在似苦木区，重点将放在完成 苦楝素、马钱子碱和蓝卡红酮的合成。 作为 由于4 β-羟基的体内系统毒性较低， 与强心内酯和蟾蜍二烯内酯相比， 以4 β-羟基withanhydroxide为中心的合成程序 为了发现一种类似物， 合理的治疗指标。 本建议第三部分重点 在一个收敛的全合成的有效细胞毒性 环缩肽，茉莉酰胺。 此外，还有许多类似物 将准备，以检查结构要求 生物活性。
