approach to solve this problem is to use an antibiotic adjuvant, which is able to potentiate the activity of antibiotic and reduce the dosage of antibiotic. Herein, we reported a novel 2-aminothiazoyl piperidine adjuvant, which enhanced the activity of colistin against Acinetobacter baumannii (A. baumannii). Two pilot libraries of 40 compounds were prepared and their adjuvant activities were evaluated. The
抗生素耐药性的迅速流行已导致严重的全球健康问题。虽然粘菌素是最后的抗生素,但它受到剂量依赖性毒性的限制。解决这一问题的一个关键途径是使用抗生素佐剂,它能够增强抗生素的活性并减少抗生素的用量。在此,我们报道了一种新型 2-氨基噻唑基哌啶佐剂,它增强了粘菌素对鲍曼不动杆菌( A. baumannii ) 的活性。准备了包含 40 种化合物的两个试验库,并评估了它们的辅助活性。最具潜力的化合物11j能够使 8 µg/mL 粘菌素的最低抑制浓度 (MIC) 降低 16 倍。此外,时间-杀灭曲线显示化合物11j具有显着的杀灭细菌的佐剂活性。预测的ADMET分析表明,2-氨基噻唑基哌啶衍生物具有良好的药物相似性和可接受的理化性质。此外,膜通透性实验表明,化合物11j有利于粘菌素破坏细菌外膜。此外,还进行了比较分子相似性指数分析 (CoMSIA) 和密度泛函理论 (DFT) 计算。从这些分析中得出的结果
