Hsp90 as drug target against bacterial and fungal infections

Heat shock proteins (Hsps) are a group of proteins that serve to improve cell survival in response to a variety of environmental stresses of the host. In recent years, Hsps gained interest in cancer therapy and as drug target against microbial infections. The antimicrobial resistance especially by Gram-negative pathogens poses a threat to mankind. The pathogen proteins of Hsp family yield Hsp90 inhibitor antibiotic reveal mechanisms that interact with the ADP/ATP-sites of Hsp90. For the present review, we used the databases and websites PubMed, SciFinder, Scopus, ProQuest, Google and Google Scholar. The review discusses the development of Hsp90 inhibitors for bacterial as well as fungal infections and how these inhibitors are being used for clinical trials. A systematic web search analysis was conducted from April to November 2019.
