Abstract
The increasing incidences of fungal infections among Covid-19 infected patients is a global public concern and urgently demands novel antifungals. Biopolymers like chitosan hold unique structural properties and thus can be utilized in the synthesis of biologically important scaffolds. To address the current scenario, the author's synthesized novel chitosan-azetidine derivative by adopting one-pot multicomponent reaction approach. The influence of chemical modification on the structural characteristics was investigated by means of spectroscopic techniques viz. FT-IR and (1)HNMR and elemental analysis. Additionally, the authors investigated the antifungal potential of chitosan-azetidine derivative against Aspergillus fumigatus 3007 and the results indicated higher antifungal effect with an antifungal inhibitory index of 26.19%. The SEM and confocal microscopy images also reflected a significant inhibitory effect on the morphology of fungal mycelia, thus reflecting the potential of synthesized chitosan-azetidine derivativeas a potential antifungal agent.
