Abstract

Polysubstituted imidazole is a heterocyclic moiety. Imidazole is a five membered ring containing two nitrogens having wide applications in medicinal chemistry. As a part of project a series of novel polysubstituted imidazole derivatives were synthesized by an efficient and environmentally adapted synthesis of multicomponent condensation (i.e. claisen ester condensation) as pharmaceutical important molecules at high yield and with high purity. Software’s like molsoft, molinspiration, osiris were used to predict toxicity and pharmacokinetic properties. All the compounds were deduced from IR, 1HNMR & MASS spectroscopic data. The derivatives were screened for anti-bacterial, anti-fungal (Bacillus subtilis, Escherichia coli, Pencillium Chrysogenum) activity by agar-cup plate method and antioxidant activity by DPPH method. Compounds 1b, 1g showed potent activity compared to ofloxacin as the reference antibacterial drug, 1g showed equipotent activity compared to fluconazole as the reference antifungal drug, compound 1b, 1d, 1g, 1j showed potent antioxidant activity when compared to ascorbic acid.

Keywords: Imidazoles, chalcones, molecular properties prediction, antibacterial activity, antifungal activity and antioxidant activity.
