The invention belongs to the field of medicinal chemistry, and discloses the application of an amino two dithiocarbamate derivative in the field of antibacterial. The compounds can restore the sensitivity of metal containing beta lactamases in Enterobacteriaceae to carbapenem antibiotics. The in vitro antibacterial experiment results show that this kind of compounds with meropenem combined, can improve the drug sensitivity of MEM. In view of carbapenem resistant NDM 1 Escherichia coli, the compounds can be carbapenem meropenem MIC value decreased, the best decreased about 40960 times. The results of zinc ion sensitivity experiments showed that zinc ion was sensitive to the recovery of MEM efficacy. Kinetic bactericidal efficacy demonstrated that the bactericidal potency of the compound in combination with MEM was also well improved. In vitro cytotoxicity test and cytotoxicity test showed that the compounds were less toxic and relatively safe. The compound can be used as a drug candidate enzyme inhibitor beta in metal model.

胺基二硫代甲酸盐衍生物在抗菌领域的应用
本专利技术属于药物化学
,涉及胺基二硫代甲酸盐衍生物作为新型金属β-内酰胺酶抑制剂在抗菌领域的应用。
技术介绍
抗生素耐药(Antimicrobialresistance,AMR)趋势如同幽灵一般不知不觉的侵袭了全球(MicrobiologyandMolecularBiologyReviews2010,74,417.)。抗生素产生耐药性已经成为公共卫生安全的主要威胁(NatureReviewsMicrobiology2015,13,42.)。细菌耐药的原因可以归结为细菌染色体突变和耐药基因水平传播两个方面。其中,细菌固有耐药是细菌自身所具备的本能。而由耐药基因的水平传播而导致的获得性耐药的产生(Nature2004,430,242.)是导致耐药性播散和多重耐药菌产生的重要原因。β-内酰胺类抗生素(青霉素,头孢菌素,碳青霉烯类和单环内酰胺类)是多年来临床广泛使用治疗细菌感染的重要抗生素。β-内酰胺酶的出现是目前临床上使用β-内酰胺类抗生素受限的主要问题,β-内酰胺酶可以通过水解β-内酰胺环,使β-内酰胺类抗生素失效(Bi ...
