Pyrimidine and its derivatives are crucial in the domains of pharmaceuticals and agricultural chemicals. In recent decades, numerous pharmacological studies have been conducted on Pyrimidine and its derivatives. However, further research is essential to address the need for biological compounds. “Chalcone is an aromatic compound that serves as the central core for various biological compounds. Chalcone is produced through an aldol condensation of 4-methoxy acetophenone with m-phenoxy benzaldehydes, utilizing a catalyst that is subsequently treated with thiourea to yield Pyrimidine. The Pyrimidine, when treated with substituted N-1,3-benzothiazole-2-yl-2-chloro amide, results in a compound”. Elemental analysis, IR, 1H-NMR, 13C-NMR), M.P. and TLC using silica gel G are employed to assess the purity of the compounds. All synthesized compounds were evaluated against four distinct strains, specifically two Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes) and two Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and were compared with standard antibiotics such as ampicillin, chloramphenicol, ciprofloxacin and norfloxacin. Additionally, all synthesized compounds were tested against Candida albicans and Aspergillus niger, with analyses conducted alongside standard antifungal agents nystatin and griseofulvin. This paper emphasizes the reactions, synthesis, spectral analysis, and microbial activities of pyrimidine-based benzothiazole derivatives. The methodology presented demonstrates superior results compared to previously published literature. Several of the compounds exhibited significant efficacy as antimicrobial and antifungal agents.
