bacteria, such as clinically important Staphylococcus aureus. The essential multifunctional enzyme, biotin protein ligase (BPL), is one potential drug target for new antibiotics. We report the synthesis and characterization of a series of biotin analogues with activity against BPLs from S. aureus, Escherichia coli, and Homo sapiens. Two potent inhibitors with K i < 100 nM were identified with antibacterial
迫切需要开发新的抗生素来抵抗耐药细菌的繁殖,例如临床上重要的金黄色葡萄球菌。基本的多功能酶生物素蛋白连接酶(BPL)是新抗生素的潜在药物靶标之一。我们报告了一系列生物素类似物的合成和表征,这些生物素类似物具有针对来自金黄色葡萄球菌,大肠杆菌和智人的BPL的活性。鉴定出K i <100 nM的两种有效抑制剂对一组金黄色葡萄球菌临床分离株具有抗菌活性(MIC 2-16杯/ mL)。鉴定并表征了具有高配体效率和同工酶之间选择性> 20倍的化合物。抗菌作用方式显示为通过抑制BPL。BPL和抑制剂之间的双分子相互作用是通过表面等离振子共振研究和X射线晶体学确定的。这些发现为具有更高效力和选择性的第二代抑制剂和抗生素铺平了道路。
