NDH-2 has a crucial role in the energy metabolism of pathogenic microorganisms, and the lack of NDH-2 or its homologs in humans makes NDH-2 an essential target for the development of antimicrobial drugs. There is a wide variety of pathogenic microorganisms that invade the human body and cause diseases; therefore, more and more inhibitors targeting NDH-2 of different pathogenic microorganisms continue to be reported. This paper first reviews the structure and function of NDH-2 and summarizes the classification of compounds targeting NDH-2. Given the relative paucity of inhibition mechanisms for NDH-2, which has greatly hindered the development of targeted drugs, the article concludes with a summary of two possible mechanisms in action: allosteric inhibition and competitive inhibition.

The metalloproteinase ADAM10 has attracted attention because it cleaves a growing amount of protein substrates close to the extracellular membrane leaflet. The process known as \"ectodomain shedding\" controls the turnover of certain transmembrane proteins that are essential for receptor signaling and cell adhesion. It may trigger nuclear transport, intramembrane proteolysis, and cytoplasmic domain signaling. Additional human illnesses linked to ADAM10 include cancer, immune system malfunction, and neurodegeneration. The difficulty in targeting proteases for medicinal reasons stems from the many substrates that these enzymes, particularly ADAM10, have. It is usually necessary to precisely identify the therapeutic beneficial window of use since blocking or accelerating a particular protease activity is linked with undesirable side effects. More knowledge of the regulatory pathways governing ADAM10 expression, subcellular localization, and activity will probably lead to the identification of viable therapeutic targets, enabling more targeted and precise manipulation of the enzyme's proteolytic activity.</p>","PeriodicalId":10859,"journal":{"name":"Current protein & peptide science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143413671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
