This methodology has the benefits of straightforward conditions, excellent yields, no work-up, environmental benign process and reusable solid catalyst. The catalyst speeds up the Schiff base reaction with less time and several Schiff bases have been synthesized and characterized with IR, 1H and 13C NMR techniques.

Their structures have been confirmed by 1H NMR, 13C NMR and LCMS analysis. The present work describes a simple, rapid, and efficient synthesis of compound 2a-2h in good yield under mild reaction condition. Shorter reaction time and convenient workup make this methodology more practical. This protocol proceeds smoothly and avoids the use of toxic organic solvents. ADMET analysis have been performed for all the synthesized compounds and observed that all the eight compounds taken for the investigation have been shown to satisfy Lipinski's rule of 5. The molecular interaction study is performed using the AutoDock software. All the 8 test compounds are found to have higher binding affinity than the control compound chloramphenicol to the E. Coli DraE adhesion. In addition antibacterial activities of all eight compounds have been determined.

Short reaction time, simple extraction procedure, substrate scope with high yield of the product, biodegradable solvent and recyclability of the catalyst without loss of its activity enhances the efficiency of the proposed protocol. The synthesized compounds are studied for their antimicrobial activity.

All the derivatives have been evaluated for antimicrobial, anticancer and antiinflammatory activities and compared with karanjin and its demethylated analog. Lipoconjugation does not seem to improve the activity of karanjin against studied bacterial and fungal strains. However, karanjin, demethylated karanjin and six lipoconjugated karanjin show moderate to good anticancer activity against prostate and breast cancer cell lines. Mild antiinflammatory response has also been observed in case of karanjin and lipoic acid-conjugated karanjin. Page(s): 115-120 2023-02-01T00:00:00Z
