piperine–amino acid ester conjugates (4a–4r) were synthesized under mild conditions and screened for their cytotoxic activities against a panel of human cancer cell lines (IMR-32, MCF-7, PC-3, DU-145, Colo-205, and Hep-2). The parent compound piperine lacked significant activity but the analogues were effective to in all tested human cancer cell lines. The introduction of d- and l-amino acid side chain
摘要在温和的条件下合成了一系列胡椒碱-氨基酸酯结合物(4a - 4r),并筛选了它们对一组人类癌细胞系(IMR-32,MCF-7,PC-3,DU-145, Colo-205和Hep-2)。亲本化合物胡椒碱缺乏显着活性,但类似物对所有测试的人类癌细胞系均有效。通过肽键将d-和l-氨基酸侧链引入胡椒碱显着增加了细胞毒活性。在测试的缀合物中,4p对具有IC 50的DU-145细胞系显示出显着的细胞毒活性为21μM。合成方案适合于产生具有各种结构基序的胡椒碱衍生物,以探索所需的活性。 图形概要在温和的条件下合成了一系列胡椒碱-氨基酸酯缀合物(4a - 4r),并筛选了它们对一组人类癌细胞系(IMR-32,MCF-7,PC-3,DU-145, Colo-205和Hep-2)。
