One-pot, Four-component Synthesis, Molecular Docking and Pharmacokinetic Studies of Tetra-substituted Imidazole Derivatives as Potential Mushroom Tyrosinase Inhibitors.

Introduction: An efficient and four-component one-pot facile synthesis of tetra-substituted imidazole is achieved by cyclo-condensation reaction of benzil with subsequent successive substitution of aromatic aldehydes, ester substituted amine and ammonium acetate via refluxing the mixture for almost two hours at 140°C.

Method: The ending point of the understudy reaction was examined by TLC after regular intervals. Synthesized 1,2,4-tetrasubstituted imidazoles were characterized by physical data and the structural features were analyzed using spectroscopic techniques such as FTIR, NMR and elemental analysis.

Results: The inhibition potential of fabricated compounds was evaluated against the mushroom based Tyrosinase (polyphenol oxidase) enzyme. Tetra-substituted imidazole derivatives demonstrated significant potent tyrosinase inhibition activities.

Conclusion: Pharmacokinetic mechanism and molecular docking studies were also carried out.
