A combinatorial series of novel quinazolin-4(3H)-ones were synthesised and their structures were established based on spectroscopic data (IR, NMR, EI-MS, and FAB-MS). The compounds were tested for inhibition of the zinc metalloproteinase thermolysin (TLN) utilizing a chemical array-based approach. Some of the compounds were found to inhibit TLN, with IC50 values ranging from 0.0115 μM (compound 3) to 122,637 μM (compound 29). Compound 3 [3-phenyl-2-(trifluoromethyl) quinazolin-4(3H)-one] (IC50 = 0.0115 μM) and compound 35 [3-(isopropylideneamino)-2,2-dimethyl-2,3-dihydroquinazolin-4 (1H)-one] (IC50 = 0.2477 μM) were found to be the most potent inhibitors.

, p. 1041 - 1063 (2007/10/03)
Some new fused quinazoline derivatives have been prepared by reacting 3-N-acyl / aroylamino quinazolin-4(3)-ones (2) with different nucleophilic reagents.The structural assignments of all the new products were based on elemental analysis and chemical and spectroscopic data, and somw of the products have been screened for their antimicrobial activity. - Key Words: synthesis; biological; fused quinazolines
