Khalil MA, Habib NS Synthesis of thiadiazol derivatives of 4(3H)-quinazolinone as potential antimicrobial agents. [Journal Article] Farmaco [Sci] 1987 Dec; 42(12):973-8.
Three series of quinazolinone derivatives were synthesised namely: 3-[4-(2-substituted amino-1,3,4-thiadiazol-5-yl)phenyl]-2-methyl-4-(3H)- quinazolinones; 3-[4-(2-substituted amino-1,3,4-thiadiazol-5-yl)anilino]-2-methyl-4-(3H)- quinazolinones and 3-[(2-substituted amino-1,3,4-thiadiazol-5-yl)methyl]-2-methyl-4(3H)-quinazolinones. The antimicrobial activity of representative compounds of these series as well as of the starting quinazolinone acids was studied.
