Problems solved by technology

Existing studies have shown that CRKP drug resistance is mainly due to the production of carbapenemase by the strain, which can efficiently hydrolyze penicillin, cephalosporin, aztreonam and carbapenem antibiotics. limited

Abstract

The present invention specifically relates to the use of BZE as an antibacterial agent. In view of the current situation that drug-resistant bacteria are increasing year by year, and the research and development cycle of antibacterial drugs is long, and the speed of marketing is slow, this field develops non-antibiotic drugs with antibacterial effects to deal with the difficult situation that drug-resistant bacteria are difficult to treat. Based on this technical idea, the present invention screens and verifies that BZE has a good antibacterial effect, and has a good in vitro complete inhibitory effect on MRSA, MDRAB and CRKP with high drug resistance. Based on the results of this study, BZE is expected to be developed as an active ingredient of a broad-spectrum antibacterial drug, which has good clinical and economic significance.

Description

technical field [0001] The invention belongs to the technical field of research and development of antibacterial preparations, and in particular relates to the application of benserazide as an antibacterial active ingredient in the preparation of antibacterial preparations. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Benserazide (benserazide, BZE) is a peripheral dopa decarboxylase inhibitor. Generally, benserazide and levodopa are used in combination for Parkinson's disease and Parkinson's syndrome. The pharmacological effect of benserazide is similar to that of carbidopa, and it is difficult to penetrate the blood-cerebrospinal fluid barrier. It is absorbed quickly...
