Compounds 4, 5, 7, 9, and 10 exhibited specific inhibitory activity against the MβL NDM-1 and CcrA with an IC50 value range of 17 to 354 μM. Analysis of the structure–activity relationship showed that both the acetamido linker and the position of the substituent on the phenyl ring played an important role in the inhibitory abilities of the inhibitors against MβLs.
图形摘要 摘要 金属-β-内酰胺酶(MβLs)是抗生素耐药性的靶酶,磷酸类药物对当代医学的发展产生了重大影响。制备并评估了 11 种乙酰氨基膦酸化合物作为 MβL 的抑制剂。化合物 4、5、7、9 和 10 对 MβL NDM-1 和 CcrA 表现出特异性抑制活性,IC50 值范围为 17 至 354 μM。构效关系分析表明,乙酰胺连接基和苯环上取代基的位置在抑制剂对MβLs的抑制能力中起着重要作用。
