their toxicity towards murine macrophages by the resazurin microtiter assay (REMA). Among the 45 derivatives, 17 compounds (3 hydroxamic acids, 9 hydrazides, and 5O-alkyl/O-acyl protected hydroxamic acids) were nontoxic against murine macrophages. When tested for their antibacterial activity, hydroxamic acid 9 h was found to be the most potent inhibitor against M. abscessus S and R only. Regarding hydrazide
以发现新的抗结核分子为目的,合成了三个新系列的 23 异羟肟酸、13 酰肼和 9O-烷基/O-酰基保护异羟肟酸衍生物,并通过光谱1 H NMR、13 C NMR、HRMS对其进行了全面表征。 ) 分析。通过刃天青微量滴定法 (REMA) 进一步对这些化合物进行了生物筛选,以了解它们对三种致病性分枝杆菌(脓肿分枝杆菌 S 和 R、海分枝杆菌和结核分枝杆菌)的体外抗菌活性,以及它们对小鼠巨噬细胞的毒性。 . 在 45 种衍生物中,17 种化合物(3 种异羟肟酸、9 种酰肼和 5O-烷基/O-酰基保护的异羟肟酸)对小鼠巨噬细胞无毒。当测试它们的抗菌活性时,异羟肟酸发现9 小时仅对脓肿分枝杆菌 S 和 R 是最有效的抑制剂。酰肼系列对脓肿分枝杆菌R、海分枝杆菌和结核分枝杆菌的活性仅7h ;而 O- 酰基保护的异羟肟酸衍生物14d和15d对 M. marinum 和 M. tuberculosis
