metal-binding features in model complexes, physicochemical properties, and biological activity. It was observed that salicylate MBIs can demonstrate a range of attractive physicochemical properties and bind to the metal in a variety of expected and unexpected binding modes. The biological activity of these novel MBIs was evaluated by measuring inhibition against two Zn2+-dependent metalloenzymes, human
金属酶抑制剂通常都需要具有金属结合药效团(MBP)来结合活性位点金属离子。然而,MBP 可能会受到物理化学的影响,从而影响抑制剂的药理学特性和药物似性。为了避免这种情况,可以识别 MBP 的有问题的特征并用等排替代品进行交换。在此,水杨酸MBP的羧基和羟基被取代,总共合成了27个水杨酸金属结合电子等排体(MBI)。在这 27 个 MBI 中,至少有 12 个代表以前未报道的化合物,并且 MBI 的 >20 的金属结合能力以前未曾报道过。检查了这些水杨酸盐 MBI 在模型复合物中的金属结合特征、理化性质和生物活性。据观察,水杨酸盐 MBI 可以表现出一系列有吸引力的理化性质,并以各种预期和意外的结合模式与金属结合。通过测量对两种 Zn 2+依赖性金属酶、人乙二醛酶 1 (GLO1) 和基质金属蛋白酶 3 (MMP-3) 以及双核 Mn 2+依赖性金属酶、流感病毒的抑制来评估这些新型 MBI 的生物活性。
