Stereoselective total synthesis of (−)-kunstleramide, a cytotoxic dienamide from the bark of Beilschmiedia kunstleri gamble, has been accomplished by using Keck's asymmetric allylation and Trost isomerization as key reactions. Application of the developed strategy for the synthesis of a series of amide analogues (8–22) was also reported. Furthermore, the synthesized compounds were evaluated for their
通过使用Keck的不对称烯丙基化和Trost异构化作为关键反应,可以完成立体选择性全合成(-)-kunstleramide,这是一种来自Beilschmiedia kunstleri赌博皮的细胞毒性二烯酰胺。还报道了已开发的策略在一系列酰胺类似物的合成中的应用(8-22)。此外,使用SRB分析评估了合成的化合物对人上皮肺癌(A549),人上皮宫颈癌(HeLa),人乳腺腺癌(MCF7)和人成神经细胞瘤(IMR32)细胞系的体外抗增殖活性。所有化合物对所有细胞系均显示出中等的抗增殖活性。一些哌嗪衍生物(17-22)以50–8μM的IC 50值强烈抑制乳腺癌细胞的生长。
