A new series of 2,6-substituted-quinazolin-4-ones was designed, synthesized, and evaluated for their in vitro DHFR inhibition, antimicrobial, and antitumor activities. Compounds 22, 33-37, 39-43, and 45 proved to be active DHFR inhibitors with IC(50) range of 0.4-1.0microM. Compound 18 showed broad-spectrum antimicrobial activity comparable to the known antibiotic gentamicin. Compounds 34 and 36 showed antitumor activity at GI(50) (MG-MID) concentrations of 11.2, and 24.2microM, respectively… Expand
