Synthesis, Computational and Pharmacological Evaluation of 7-(2-(2- (3- (Substituted Phenyl) Acryloyl) Phenoxy) Ethoxy)-4-Methyl-2H-Chromen- 2-Ones as CNS Agents.

Background: Motivated by the exciting biological potential for the use of hybrid molecules in medicine and therapy. It is anticipated that the coumarin-chalcone hybrids for skeletal muscle and antianxiety action will be investigated using a chemical hybridization technique.

Objective: Due to its numerous benefits, including high effectiveness, mode of action at receptors, minimal adverse effects, and improved pharmacokinetic features, naturally occurring and synthesized hybrid compounds are prospective sources for novel drug development techniques. In opinion of these applications, we here designed some coumarin-chalcone hybrids and explored them for skeletal muscle and antianxiety potential.

Methods: Using a chemical hybridization strategy, coumarin-chalcone hybrids have been synthesized and evaluated for skeletal muscle and antianxiety activity. The target compounds were synthesized by reaction of 7-hydroxy-4-methylcoumarion with haloalkane to afford 7-(2- bromoethoxy)-4-methyl-2H-chromen-2-one which was further treated with hydroxychalcones. The structures of target compounds were confirmed on the basis of their Melting Point, Thin Layer Chromatography, IR, 1HNMR and Mass studies. The computational properties of target compounds were also determined through online software. Skeletal muscle and antianxiety potential were performed in Swiss albino mice.

Results: The coumarin-chalcones hybrids showed skeletal muscle and antianxiety potential in Swiss albino mice and computational properties of the target compounds were also showed similarity as compared with diazepam.

Conclusion: Among the target compounds, the fluoro group containing compound was found to be more potent as compared to the standard drug diazepam.
