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.

该提案的重点是抗肿瘤剂的合成。 在木工区域，将重点放在完成 墨西哥蛋白酶，bruceantin和glaucarubinone的合成。 作为 4beta-Hydroxy体内系统中毒性较低的结果 与甲烯酚和bufadienolides有关 合成程序以4beta-hydroxy withanolide E为中心 是为了发现拥有一个的模拟 合理的治疗指数。 该提案的第三部分重点 关于有效细胞毒性的收敛性总合成 环肽肽，Jaspamide。 另外许多类似物 为了检查结构要求 用于生物活性。
