objective(s) quinazolinones are heterocyclic compounds, with biological and pharmacological activities, such as inhibiting some proteins, enzymes and reducing blood lipids. materials and methods following previous results of our group, effects of two new derivatives of quinazolinones 9(3)-quinazolinone-2-propyl-2-phenylethyl (qppe) and 9(3)-quinazolinone-2-ethyl-2-phenylethyl (qepe) on livers, ...

an efficient synthesis of 3-substituted or 2,3-disubstituted 4(3h)-quinazolinones from benzoxazin-4-ones and primary amines under microwave irradiation in unsealed vessels is described.

Quinazolinones are interesting molecules with a wide range of biological activities. We prepared a number of quinazolinone derivatives by the condensation of 5-bromo- or 5-nitro-substituted anthranilic acids with chloro-acyl chlorides. Anthranilic acid derivatives were treated with either 3-chloro-propionyl chloride or 4-chloro-butyryl chloride to yield the corresponding N-acyl-anthranilic acid...

A series of 4(3H)-quinazolinones structurally related to 2-methyl-3-o-tolyl-4(3H)-quinazolinone (methaqualone, 3) were synthesized and evaluated for anticonvulsant activity. Preliminary screening of these compounds revealed that 2-[2-oxo-2-(4-pyridyl)ethyl]-3-aryl-4(3H)-quinazolinones 6l and 8i, 8k, and 8p-r having a single ortho substituent on the 3-aryl group had the most promising anticonvul...

Quinazolinones, water insoluble heterocyclic compounds, have various biological and pharmacological properties (anti-bacterial, anti-inflammation, sedation and anti-depression) are also used for the treatments of cancer and HIV. Our previous results proved that new derivative of quinazolinones is toxogenic and teratogenic in mouse. Pregnant Balb/C mice (n=8) were divided into 3 groups of contro...
