Results of molecular modelling confirmed the interaction with the allosteric site of PBP2a as a probable MDR-reversing mechanism. In RTE, the compounds inhibited AcrAB-TolC even to 90% (19). The 4-phenylbenzylidene derivative (15) demonstrated significant MDR-reversal “dual action” for β-lactam antibiotics in MRSA and inhibited AcrAB-TolC in K. aerogenes. 15 displayed also satisfied solubility and safety
在寻找克服抗菌素耐药性的有效策略时,探索了一系列新的含吗啉的5-芳基亚氨基咪唑酮,它们在胺部分或咪唑酮的第5位不同,作为潜在的革兰氏阳性和革兰氏阴性细菌抗生素佐剂。测试了化合物(7 – 23)在耐甲氧西林金黄色葡萄球菌(MSSA)ATCC 25923和耐甲氧西林的金黄色葡萄球菌MRSA 19449中的奥沙西林佐剂特性。化合物14 – 16还与各种抗生素联合测试。进行分子建模以评估潜在的作用机理。微量稀释和实时流出(RTE)的测定中的菌株进行K.气肠杆菌,以确定化合物的潜在7 - 23阻止的多药运出泵的AcrAB-TolC外。通过实验确定类药物性质。两种化合物(10,15含非稠合芳族环),显著在MRSA 19449苯唑西林的MIC降低,而15进一步增强了氨苄西林的有效性。分子建模的结果证实与PBP2a的变构位点的相互作用是可能的MDR逆转机制。在RTE中,这些化合物甚至可抑制AcrAB-TolC达到90%(19)。4-
