AntiHIV, antibacterial and antifungal activities of some novel 2-methyl-3-(substituted methylamino)-(3H)-quinazolin-4-ones

The title compounds 2-methyl-3-(substituted methylamino)-(3 H )-quinazolin-4-ones were synthesized by condensing the active hydrogen atom of the amino group of 3-amino-2-methyl-(3 H )-quinazolin-4-one with formaldehyde and appropriate amines. Their structures were confirmed by spectral data (IR, 1H-NMR and Mass) and the purity was ascertained by elemental analysis. Investigation of antimicrobial activity of the test compounds was performed by agar dilution method against 7 pathogenic bacteria, 3 pathogenic fungi and antiHIV activity against replication of HIV-1(IIIB) and HIV-2 (ROD) in MT-4 cells. The compounds exhibited significant antibacterial and antifungal activities.
