a topical antibacterial agent, is an inhibitor of Staphylococcus aureus primaseDnaG (SaDnaG) with low-micromolar minimum inhibitory concentrations against several S. aureus strains, including methicillin-resistant bacteria. Mechanistic studies of dequalinium and a series of nine of its synthesized analogues revealed that these compounds are single-stranded DNA bisintercalators that penetrate a bacterium
细菌中的许多必需酶仍然是抗菌剂的有希望的潜在靶标。在这项研究中,我们发现地喹铵是一种外用抗菌剂,是金黄色葡萄球菌引物酶 DnaG ( Sa DnaG) 的抑制剂,对几种金黄色葡萄球菌具有低微摩尔的最低抑制浓度菌株,包括耐甲氧西林细菌。dequalinium 及其一系列九种合成类似物的机理研究表明,这些化合物是单链 DNA 双嵌入剂,可通过破坏细菌膜来穿透细菌。该系列中最好的化合物可能直接与 DnaG 相互作用,抑制葡萄球菌细胞生长和生物膜形成,并且对哺乳动物细胞没有显着的溶血活性或毒性。该化合物是进一步开发新型抗葡萄球菌治疗剂的绝佳先导。
