A series of hybrid compounds of bestatin (1) and actinonin (3), which promote degradation of cellular inhibitor of apoptosis protein 1 (cIAP1), were designed and synthesized. Structure-activity relationship studies indicated that absolute configuration, hydrophobicity at the alpha-position of the internal amide carbonyl group, and the presence of a small substituent at the alpha-position of the ester
设计并合成了一系列促进细胞凋亡蛋白1(cIAP1)降解的Bestatin(1)和actinonin(3)杂合化合物。构效关系研究表明,绝对构型,内部酰胺羰基的α位疏水性以及酯基的α位小取代基的存在是表达有效cIAP1降解的重要因素-促进活动。在制备的化合物中,HAB-5A(30b)表现出最强的活性(IC(50)= 0.53 microM)。
