Synthesis and antimicrobial evaluation of novel substituted pyrimidine scaffold
摘要:
Synthesis and biological evaluation of substituted pyrimidine derivatives containing 4-amino and 5-cyano substituted derivatives are described. Biginelli typed three component reactions between an aldehyde, malononitrile, and a urea constituent give a rapid facile pyrimidine ring. The constitution of the products has been delineated by elemental analysis and spectral analysis. The products were assayed for their in vitro biological assay antibacterial activity against S. pyogenes MTCC-442, S. aureus MTCC-96, E. coli MTCC-443, and B. subtilis MTCC-441 bacterial strain and antifungal activity against Aspergillus niger MTCC-282 and Candida albicans MTCC-227 at different concentrations, which compared with Ampicillin, Chloramphenicol, Ciprofloxacin, Norfloxacin, and Griseofulvin as standard drug which are presented.

Various 2-thioxo and 2-oxo-1,2,3,4-tetrahydro-pyrimidine-5-carbonitriles were synthesized in very high yields in 40min through a direct condensation of an equimolar amount of an aldehyde, malononitrile, and thiourea/urea under ball mill solvent-free and catalyst-free conditions.
