biochemical roles of many FACLs remain poorly characterized while the functionally non-redundant FAALs are much better understood. Here we describe the systematic investigation of 5′-O-[N-(alkanoyl)sulfamoyl]adenosine (alkanoyl adenosine monosulfamate, alkanoyl-AMS) analogs as potential multitarget FadD inhibitors for their antitubercular activity and biochemical selectivity towards representative FAAL and
结核分枝杆菌( Mtb ) 的脂质代谢依赖 34 种脂肪酸腺苷酸化酶 (FadDs),可分为两类:参与脂质和胆固醇分解代谢的脂肪酰基辅酶 A 连接酶 (FACL) 和长链脂肪酰基-AMP 连接酶 (FAAL) ) 参与Mtb 中发现的许多必需和赋予毒力的脂质的生物合成。许多 FACL 的精确生化作用仍不清楚,而功能非冗余的 FAAL 则更好理解。这里,我们描述的5'-系统调查ö - [ ñ - (链烷酰基)氨磺酰基]腺苷(烷酰基一denosine米ONO小号ulfamate, alkanoyl-AMS) 类似物作为潜在的多靶点 FadD 抑制剂,因为它们具有抗结核活性和对代表性 FAAL 和 FACL 酶的生化选择性。我们鉴定了几种有效的化合物,包括 12-叠氮十二烷酰基-AMS 28、11-苯氧基十一烷酰基-AMS 32和壬氧基乙酰基-AMS 36,其对结核分枝杆菌的最小抑制浓度 (MIC)范围为
