Propargylated monocarbonyl curcumin analogues: synthesis, bioevaluation and molecular docking study

Abstract

In the current experimental study, we have synthesised new monocarbonyl curcumin analogues bearing propargyl ether moiety in their structure and evaluated for in vitro antifungal and radical scavenging activity. The antifungal activity was carried out against five human pathogenic fungal strains such as Candida albicans, Fusarium oxysporum, Aspergillus flavus, Aspergillus niger and Cryptococcus neoformans. Most of the curcumin analogues displayed excellent to moderate fungicidal activity when compared with standard drug Miconazole. Also, synthesised analogues exhibited potential radical scavenging activity as compared with standard antioxidant Butylated hydroxyl toluene (BHT). Based on biological data, structure-activity relationship (SAR) were also discussed. Furthermore, in silico computational study was carried out to know binding interactions of synthesised analogues in the active sites of enzyme sterol 14α-demethylase (CYP51).
