and topoisomerase IV inhibitors that demonstrate potent activity against a range of Gram-positive and selected Gram-negative organisms, including clinically-relevant and drug-resistant strains. In part 1, we present a detailed structure activity relationship (SAR) analysis that led to the discovery of our previously disclosed compound, REDX05931, which has a minimum inhibitory concentration (MIC) of
针对细菌感染的药物有效性令人震惊的下降,迫切需要开发新的抗菌剂来绕过细菌耐药机制。我们在此报告了一系列 DNA 促旋酶和拓扑异构酶 IV 抑制剂,它们对一系列革兰氏阳性和选定的革兰氏阴性生物体(包括临床相关和耐药菌株)表现出有效的活性。在第 1 部分中,我们提出了详细的构效关系 (SAR) 分析,导致我们发现了我们之前公开的化合物 REDX05931,该化合物对耐氟喹诺酮类金黄色葡萄球菌的最小抑制浓度 (MIC) 为 0.06 μg mL -1。虽然在体外 hERG 和 CYP 抑制阻止了进一步的发展,它验证了一种合理的设计方法来解决这一紧迫的未满足的医疗需求,并为进一步优化提供了一个支架,在第 2 部分中介绍。
