microsomes and no hERG channel inhibition liability were identified and evaluated in vivo for pharmacokinetic properties. Mtb-mediated permeation and metabolism studies revealed that the carbamates were acting as prodrugs. Toward mechanism of action elucidation, selected compounds were tested in biology triage assays to assess their activity against known promiscuous targets. Taken together, these data suggest
筛选抗结核分枝杆菌( Mtb )的小极性分子文库,鉴定了有效的苯并杂环肟氨基甲酸酯系列。该系列经历了以构效关系研究为基础的药物化学进展,以确定用于概念验证研究的化合物并定义先导优化策略。在肝微粒体中具有良好稳定性且无 hERG 通道抑制倾向的氨基甲酸酯和游离肟领先化合物被鉴定并在体内评估了药代动力学特性。山地车介导的渗透和代谢研究表明氨基甲酸酯充当前药。为了阐明作用机制,在生物学分类试验中测试了选定的化合物,以评估它们对已知混杂靶标的活性。综上所述,这些数据表明这些抗结核药物有一种新颖但未知的作用模式。
