title: Synthesis and antimicrobial evaluation of chalcone and syndrome derivatives of 4(3H)-quinazolinone.
abstract: The increasing clinical importance of drug-resistant bacterial pathogens has encouraged additional microbiological and antibacterial research. New chalcone and sydnone derivatives of 4(3H)-quinazolinone were synthesized and evaluated for their antibacterial and antifungal activity. The microorganisms used were Escherichia coli ATCC 25922 as Gram-negative bacteria, Staphylococcus aureus ATCC 19433 as Gram-Positive bacteria and Candida albicans as yeast like fungi. The most potent compound was the nitroso derivative 6b, which exhibits interesting antibacterial and antifungal activities.
