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 liver...

Quinazolinones are interesting materials because of their valuable biological effects. In this study some new 2,3-disubstituted-4(3H)quinqzolinone derivatives were synthesized from anthranilic acid in six steps by introducing a new chiral center to the aliphatic side chain of the quinazolinone. In the last step, a single acylation on the hydrazine moiety afforded final compounds. The structures...

A series of mannich bases (3a-3j) were synthesized by the reaction of 4-[2-methyl-4-oxo-4H-quinazolin-3-yl] benzoic acid (2) with formaldehyde and appropriate amines by conventional technique. The procedure afforded various quinazolinone derivatives with 75% yield. Structures were characterized by means of spectral data. All the synthesized compounds were subjected to biological evaluation for ...

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 ...

Objective(s): Hybridization of bioactive natural and synthetic compounds is one of the most promising novel approaches for the design of hit and lead compounds with new molecular structures. In this investigation, a series of novel hybrid structures bearing quinazolinone, benzofuran and imidazolium moieties were designed and synthesized. Materials and Methods:Novel hybrid compounds were prepare...

Cancers, particularly, breast cancer is one of the deadliest disease in women and requires to be treated with lowest side-effects toxicity. Quinazolinone Benzimidazole nucleus are privileged reported anti-cancer activity. Hence, combined derivatives 3-((1H-Benzo[d]imidazol-2-yl)methyl)-2-phenylquinazolin-4(3H)-one E(1-8) were prepared tested for cytotoxicity on MCF-7 cell line. Compound E6 show...

WIDE RANGE OF QUINAZOLINONE BIOLOGICAL PROPERTIES INCLUDING antibacterial, anticancer, and anti-inflammatory activities encouraged us to synthesis some fused quinazolinone derivatives. Anthranilic acid was condensed with chloro acylchloride followed by dehydration to form the benzoxazinone intermediate; subsequent addition of an amine provided the fused quinazolinones. Deoxyvasicinone which was...
