AntiHIV, Antibacterial And Antifungal Activities Of Some 2,3-Disubstituted Quinazolin-4(3H)-Ones

The title compounds 2-mercapto-3-(substitutedmethylamino) quinazolin-4(3H)-ones were synthesized by condensing the active hydrogen atom of 3-amino group of 3-amino-2-mercapto quinazolin- 4(3H)-one with formaldehyde and the desired amines. Investigation of antimicrobial activity of the compounds was performed by agar dilution method against 6 pathogenic bacteria, 3 pathogenic fungi and antiHlV activity against replication of HIV-1 (IIIB) and HIV-2 (ROD) in MT-4 cells. The compounds exhibited significant antibacterial and antifungal activities.
