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.

Oxidation of 3-amino-2-trifluoromethylquinazolin-4(3H)-one 6 with lead tetraacetate in dichloromethane gives the title 3-acetoxyamino derivative 7 which is isolable at room temperature and considerably more stable than the corresponding 2-alkyl substituted analogues. Compound 7 aziridinates alkenes in yields which are consistently higher than those from the 2-alkyl substituted analogues. Aziridinations
