Synthesis, pharmacological evaluation and molecular docking studies of indanone derivatives

A new series of isoxazole fused indanones were synthesized form indane-1,3-dione. The newly synthesized derivatives were confirmed by IR, 1H NMR, and mass spectral data. The synthesized title compounds were evaluated for analgesic, anti-inflammatory, and antimicrobial activities. The modifications carried out in indanone had a positive effect in anti-inflammatory activity when compared to that of other pharmacological activities. The compounds BD6, BD7, BD9, BD10, and BD11 showed good anti-inflammatory activity when compared to that of standard indomethacin. BD3, BD4, and BD5 compounds possess moderate anti-inflammatory activity. Some compounds possess moderate analgesic and antimicrobial activity. Docking study reveals that isoxazole nucleus is essential for biological activity. It was concluded that the fusion of isoxazole with indanone nucleus will increase anti-inflammatory activity than analgesic and antimicrobial activity.
