目的:新型氮杂多肽酰肼类衍生物的设计和合成及其抗肿瘤活性研究。方法:以脯氨酸甲酯盐酸盐为原料,通过与苄氧羰基丙氨酸反应,在肼中肼解,得到所需中间体,进而与富马酸单酯反应得到目标化合物;和溴乙酸叔丁酯反应,三氟乙酸中脱去叔丁氧基,再与取代胺或氨水反应得到目标化合物。用MTT法测试合成的氮杂多肽酰肼类衍生物对肿瘤细胞的抑制活性。结果:合成了10个氮杂多肽酰肼类衍生物,其中有6个化合物对肿瘤细胞表现出抑制活性。结论:初步建立了氮杂多肽酰肼类衍生物的合成方法及其对肿瘤细胞抑制活性的构效关系。  相似文献

Though many chiral amines such as l-proline and its derivatives have proven to be versatile catalysts in many reactions, l-prolinol was seldom used as organocatalyst for reactions. Herein, we report the first l-prolinol catalyzed asymmetric Michael addition of cyclohexanone to nitroolefins in the presence of benzoic acid to afford Michael adducts with high diastereoselectivities (87:13–>99:1) and enantioselectivities (82–96%).  相似文献

Withaferin-A was reacted with three model biological nucleophiles: ethyl mercaptan, thiophenol, and -cysteine ethyl ester. Under neutral or alkaline conditions, each of the thiols underwent facile Michael addition with the antitumor agent. The most chemically reactive site for Michael Addition reactions with the model thiols was the unsaturated A-ring of withaferin-A. The possible significance of this reaction with regard to antitumor activity is discussed.  相似文献
