A new class of antibiotics effective against methicillin-resistant Staphylococcus aureus (MRSA) is disclosed (Formula V). Compounds of this class can impair cell-wall biosynthesis by binding to both the allosteric and the catalytic domains of penicillin-binding protein (PBP) 2a. This class of antibiotics holds promise in reversing obsolescence of staphylococcal PBPs as important targets for antibiotics. Embodiments of the invention thus provide novel antibacterial compounds that target penicillin-binding proteins and/or other important cellular targets. Methods for inhibiting the growth and/or replication of bacteria using the compounds described herein are also provided. Various embodiments exhibit activity against gram positive bacteria, including drug-resistant strains of Staphylococcus aureus.
本研究公开了一类对耐
甲氧西林金黄色葡萄球菌(MRSA)有效的新型抗生素(式 V)。该类化合物通过与
青霉素结合蛋白(PBP)2a 的异构和催化结构域结合,可损害细胞壁的
生物合成。这一类抗生素有望扭转葡萄球菌 PBPs 作为抗生素重要靶点的过时局面。因此,本发明的实施方案提供了针对
青霉素结合蛋白和/或其他重要细胞靶点的新型抗菌化合物。本发明还提供了使用所述化合物抑制细菌生长和/或复制的方法。各种实施方案对革兰氏阳性细菌,包括
金黄色葡萄球菌的耐药菌株具有活性。
