In the title compound, C24H17Cl2N3O3, the quinazolinone ring system is close to planar (r.m.s. deviation = 0.0132 Å), with the imide unit almost perpendicular to it, subtending a dihedral angle of 89.1 (1)°. However, the imide unit itself is not planar, the dihedral angle between the two O=C-N components being 34.6 (1)°. The dihedral angle between the two chlorobenzene rings is 40.50 (7)°, whil...

2- Ethoxy-4(3H) quinazolinone 1 was synthesized and allowed to react with various halides, namely: alkyl, benzyl, allyl, acyl, haloacetyl, crotonyl, benzoyl, 2-furoyl and 1-naphthalenesulphonyl halides affording quinazoline and quinazolinone derivatives. The reactions of compound 1 with phosphorus oxychloride, phosphorus pentasulfide, ethyl chloroformate, ethyl chloroacetate, ?-bromoglucose tet...

Quinazolinone is a compound made up of two fused six member simple aromatic rings-benezene and pyrimidine ring and have been reported to posses versatile type of biological activities such as anticancer, anticonvulsant, antiinflammatory, antihelminthic, antimicrobial activities. A series of novel substituted[1,2,4]triazolo[1,5c]quinazolinone derivatives (K11-19) were synthesized by mannich reac...

Quinazolinone derivatives are essential units in a wide range of relevant pharmacophores with a broad spectrum of abilities. Due to their wide range of pharmacological and therapeutic activities including anticonvulsant, anti-inflammatory, hypolipidemic, anticancer, and anti-ulcer, the synthesis of quinazolinone moieties as a privileged class of fused heterocyclic compounds, have received much ...

Quinazolinones represent a class of sedative and anticancer drugs. Quinazolinones-based compounds have ability to suppress prostate tumor growth via apoptosis. Apoptosis is very common in embryos and adults of normal and injured mammalian testes. Effects a new derivative of quinazolinone (4(3H) quinazolinone-2-ethyl-2-phenyl ethyl (QEPE)), on the testis of Balb/C mice embryos were investigated....

We recently reported on the discovery of a novel antibacterial (2) with a 4(3H)-quinazolinone core. This discovery was made by in silico screening of 1.2 million compounds for binding to a penicillin-binding protein and the subsequent demonstration of antibacterial activity against Staphylococcus aureus. The first structure-activity relationship for this antibacterial scaffold is explored in th...

Quinazolinone backbone is present in a large number of bioactive substances. Since remarkable cytotoxic activity is associated with some 4(3H)-quinazolinones, in this study some 4(3H)-quinazolinone were synthesized and screened against HeLa cells. The synthesis was performed via reaction of anthranilic acid with dicarboxylic anhydrides to produce carboxylic acids derivatives. The products were ...

Constructing ideal adsorbent for the capture of radioactive iodine often requires both high adsorption capacity and fast kinetics. However, this remains a challenging issue. Herein, we present an effective method to idealize with ultrahigh rate through construction quinazolinone-anchored covalent organic frameworks (COFs). Post-synthesis modification was employed functionalize two vinyl free-st...

As part of the development of enzyme-mediated cancer imaging and therapy, a novel technology to entrap water-insoluble radioactive molecules within solid tumors, we show that a water-soluble, radioactive quinazolinone prodrug, ammonium 2-(2'-phosphoryloxyphenyl)-6-[125I]iodo-4-(3H)-quinazolinone (125IQ(2-P)), is hydrolyzed by alkaline phosphatase to a water-insoluble, radiolabeled drug, 2-(2'-h...

In the title compound, C(17)H(17)N(3)O(2), the quinazolinone ring system is essentially planar. The benzene ring is twisted with respect to it by a dihedral angle of 32.7 (5)°. The mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond, and the crystal structure is stabilized by inter-molecular O-H⋯N inter-actions.
