urgent task for treatment of ‘superbug’ infectious diseases. In this study, we found that naturally occurring houttuynin and its sulfonate derivatives might be effective NDM-1 inhibitors with novel mechanism, i.e. the attribute of partially covalent inhibition of sulfonate derivatives of houttuynin against NDM-1. Primary structure–activity relationship study showed that both the long aliphatic side chain
发现新型NDM-1抑制剂是治疗“超级细菌”传染病的紧迫任务。在本研究中,我们发现天然存在的鱼腥草素及其磺酸盐衍生物可能是有效的NDM-1抑制剂,其机制新颖,即鱼腥草素磺酸盐衍生物对NDM-1具有部分共价抑制作用。一级构效关系研究表明,长脂肪族侧链和醛基弹头对于对抗NDM-1的效率至关重要。链较长的同系物 ( to ) 显示出较强的抑制活性,IC 范围为 1.1–1.5 μM,而链较短的同系物则抑制较弱。进一步的细胞水平协同实验证实,这4种化合物(32 μg/mL)均恢复了美罗培南(MER)对BL21/pET15b-的抗菌活性。
