Inhibitors of CPH1-MAP Kinase Pathway: Ascertaining Potential Ligands as Multi-Target Drug Candidate in Candida albicans

A number of proteins contributing in pathogen’s virulence mechanisms offer a potential target for anticandidal therapeutics. CPH1 and its regulatory proteins Cst20, Hst7, Cek1 (MAPK cascade) administers filamentation and morphogenesis in human pathogenic fungus Candida albicans. These proteins are essential targets for their involvement in the successful establishment of the fungi within the host. In silico drug design using virtual screening, docking and (ADME)/Tox analysis for identification of lead compounds is an economic strategy for the development of potent anticandidal agent. The study divulged five persuasive ligands (2-O-prenyl coumaric acid, 2-nitro-4-methyl-cinnamaldehyde, 3,5-diprenyl-4-coumaric acid, VT1161, T-2307) out of 25, which collectively inhibited Cst20, Hst7, Cek1 in C. albicans. They can hence be used as natural drug leads for designing more effective inhibitors of multiple targets for C. albicans survival and progression of the disease. This study will enhance our understanding of the phenomenon “multiple targeting” and multi-target drug discovery further accelerating efficient broad-spectrum antifungal therapeutics development in near future. This study provides a good platform to eradicate the issue of “target shortage” that might facilitate the discovery of novel drugs in near future because the prolonged use of antibiotics over the years has transformed pathogenic fungus into resistant to many drugs.
