TMPK (MtTMPK) inhibitors, and reported here the design of a novel series of non-nucleoside inhibitors of MtTMPK. The inhibitors display hitherto unexplored interactions in the active site of MtTMPK, offering new insights into structure–activity relationships. To investigate the discrepancy between enzyme inhibitory activity and the whole-cell activity, experiments with efflux pump inhibitors and efflux
近年来,一直致力于开发细菌DNA生物合成必不可少的酶胸苷酸激酶(TMPK),以开发新的抗菌剂,包括抗结核分枝杆菌(结核分枝杆菌)。为了应对对更有效的抗结核药物的日益增长的需求,我们在先前探索新型和有效结核分枝杆菌TMPK(Mt TMPK)抑制剂的努力基础上,在此报告了一系列新型非核苷的设计的抑制剂山TMPK。抑制剂在Mt的活性位点显示出迄今未探索的相互作用TMPK,提供有关结构与活动关系的新见解。为了研究酶抑制活性和全细胞活性之间的差异,进行了外排泵抑制剂和外排泵敲除突变体的实验。当确定外排泵mmr敲除突变体时,特定抑制剂的最小抑制浓度显着增加,这部分解释了观察到的不和谐。
