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 mu M (compound 3) to 122,637 mu M (compound 29). Compound 3 [3-phenyl-2-(trifluoromethyl) quinazolin-4(3H)-one] (IC50 = 0.0115 mu M) and compound 35 [3-(isopropylideneamino)-2,2-dimethyl-2,3-dihydroquinazolin-4 (1H)-one] (IC50 = 0.2477 mu M) were found to be the most potent inhibitors.

New quinazolone derivatives: Synthesis, Spectroscopic, X-ray, DFT calculation and Biological activity studies
Quinazolone is a type of heterocyclic scaffold with extensively biological activities. Many reports have shown that quinazolonederivatives played an important role as antidiabetic, antithrombotic, antiviral, antibacterial and antitumor reagents. Based on the broadly biological activities, a new series of quinazolonederivatives was designed and synthesized. These compounds were characterized by 1H-NMR
