Abstract
In this paper, the synthesis of novel pyrazoles and their in vitro anti-inflammatory and in-vitro antifungal assay have been reported. These compounds were docked into the inducible nitric oxide synthase (iNOS) oxygenase dimer. The compounds 3c, 7a, 7c, 8a, 8c have exhibited the C-score values more than the standard drug aminoguanidine (5.35). Upon the favorable docking results, the anti-inflammatory potential of the title compounds was determined by analyzing the reduction in the NO production by activated macrophages using in-vitro assays. The compounds 4c, 5c, 6a, 6c, 7a, 8a, 8c exhibited the potential anti-inflammatory activity at 1.00 µg/mL. Further, the docking study of the title compounds 3b, 3c, 4a, 5a, 5c with Aspergillus fumigatus N-myristoyl transferase (NMT) showed appreciable C-score values as against that of fluconazole (5.56). This observation was further substantiated by in-vitro antifungal activity in which the compounds 3b–c, 4a–c, 5a–c, 6a–c, 7a–b, 9a–c have excellent inhibition against A. fumigatus.
