Optimization of adenosine analog inhibitors of bacterial NAD+-dependent DNA ligase is discussed. Antibacterial activity against Streptococcus pneumoniae and Staphylococcus aureus was improved by modification of the 2-position substituent on the adenine ring and 3′- and 5′-substituents on the ribose. Compounds with log D values 1.5–2.5 maximized potency and maintained drug-like physical properties.
讨论了细菌NAD +依赖性DNA连接酶的腺苷类似物抑制剂的优化。通过修饰腺嘌呤环上的2-位取代基和核糖上的3'-和5'-取代基可以提高对肺炎链球菌和金黄色葡萄球菌的抗菌活性。log D值为1.5–2.5的化合物可 最大化效价并保持类似药物的物理特性。
