for their catalytic processes, highlighted by the fact that the hydrolytic water molecule in each approaches the ester of the intermediary acyl-enzyme species from the opposite ends. 6,6-Bis(hydroxylmethyl)penicillanate was designed as an inhibitor that would impair the approach of the hydrolytic water molecule in either of these enzymes upon formation of the acyl-enzyme species. The design, synthesis
A和C类的β-内酰胺酶是细菌病原体中对β-内酰胺类抗生素最普遍的两个耐药决定簇。这两种酶在其催化过程中都遵循不同的机理,这一点突出了一个事实,那就是水解酶分子中的每一个都从相反的末端接近中间酰基酶物种的酯。6,6-双(羟甲基)青霉酸酯被设计为一种抑制剂,在形成酰基酶物种时会削弱这些酶中任一酶的水解水分子的作用。本文公开了该抑制剂的设计,合成和动力学评估。
