Abstract
The appearance to antimicrobial resistance to the antimicrobial agent has become a matter of high concern for health care professionals since last ten years. It will an effort to establish new pyrimidine derivatives as improved antimicrobial agent. In this particular series of novel substituted pyrimidine derivatives (PK1-PK5) were synthesized by simple condensation reaction between different substituted aldehydes and 3 acetyl -2,4-dimethyl pyrrole in presence of a strong ethanolic base to yield the pyrrolyl chalcones. The final synthesized pyrimidine derivative is prepared by the cyclization of pyrrolyl chalcones with urea in presence of KOH as base. The structures of the final synthesized compounds were characterized by IR, mass and 1 H NMR spectra. The synthesized compounds were screened for their antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosaby cup plate method. Most of the compounds exhibited promising antibacterial activity.
