Abstract: In a wide search program toward new antimicrobial agents, a seri of heterocyclic chalcones have been synthesized by condensing benzaldehyde derivatives with heteroarylmethylcetone in potassium hydroxide methanol according to the Claisen-Schmidt condensation at room temperature. The synthetic chalcones have been determined by IR spectroscopy and 1H-NMR spectroscopy. The antimicro-bacterial activity of the novel products was evaluated against bacteria such as Staphylococcus aureus, Pseudomonas aeruginosae, E. coli and fungi such as Candida albicans, dermatophytes. The result shows that pyridine moiety may show antibacterial effect stronger than that of thiophene or furan. Heterocyclic chalcones with hydroxyl group on B ring at position 2 or 3 are considered as lead compounds for generation of new potential antimicrobial drugs in future.

First of all congratulation. Good to attend this virtual presentation. A novel work for new type of heterocyclic chalcone derivatives. I wonder the new derivatives with substituted halogens at B-ring as well as synthesis of pyridin-3-yl, pyridin-4-yl derivatives. All the best

Thanks Dr. Santosh Kumar Gurung for your attention as well as good commendation. We are conducting our project with other series of chalcones in which B ring possess chlorine atom as well as A ring are pyridin-3-yl, pyridin-4-yl moieties. We will submit them in the next time. Best regards.
