J Enzyme Inhib Med Chem:新型抗菌剂可有效抗菌

2018-05-04 MedSci MedSci原创

多药耐药性细菌感染的发病率逐渐增加,迫切需要开发新的抗生素。开发干扰FtsZ活性的小分子是一种有前途的用于寻求高效力抗菌药物的方法。本研究中,研究人员合成了一系列新的喹啉衍生物并探究其抗菌活性。结果显示,这些化合物对包括MRSA,VRE和NDM-1大肠杆菌在内的不同细菌菌株具有很强的抗菌活性。在这些衍生物中,含有4-氟苯基(A2)的化合物表现出优异的抗菌活性,其对耐药菌株的MICs低于甲氧西林和万

多药耐药性细菌感染的发病率逐渐增加,迫切需要开发新的抗生素。开发干扰FtsZ活性的小分子是一种有前途的用于寻求高效力抗菌药物的方法。本研究中,研究人员合成了一系列新的喹啉衍生物并探究其抗菌活性。

结果显示,这些化合物对包括MRSA,VRE和NDM-1大肠杆菌在内的不同细菌菌株具有很强的抗菌活性。在这些衍生物中,含有4-氟苯基(A2)的化合物表现出优异的抗菌活性,其对耐药菌株的MICs低于甲氧西林和万古霉素。生物学结果表明,这些喹啉衍生物可以破坏GTP酶活性和FtsZ的动态组装,从而抑制细菌细胞分裂,然后导致细菌死亡。

综上所述,该研究结果表明,这些化合物值得进一步评估开发针对FtsZ的新型抗菌剂。
