P HOSPHODIESTERASE 7A enzyme is one of the most recent targets for designing potent anti-inflammatory agents with minimal side effects. Quinazolinones are unique building blocks of wide biological activities. Different quinazolinones were reported to act as Phosphodiesterase 7A inhibitors anti-inflammatory particularly against chronic inflammation and autoimmune disease. Ultrasound is a green convenient method for synthesis of different heterocyclic ring system that is advantageous in terms of yield and reaction time. Ultrasound was used for one pot synthesis of 3-substituted 6-aryldihydroisoindolo[2,1-a] quinazolin-5,11diones and 3-arylquinazolin-2,4(1H,3H)-diones. Seventeen compounds were synthesized in good yields. The synthesized compounds were inspected for in vitro inhibitory activity against phosphodiesterase7A enzyme. Molecular docking was used to study the mode of interaction of all the synthesized compounds into the enzyme phosphodiesterase 7A binding site. Five compounds showed high inhibitory activity of enzyme Phosphodiesterase 7A at micro-molar level compared to reference drug. The compounds showed good recognition at the enzyme binding site in the molecular docking. There was a good agreement between the molecular docking and the biological screening results.

“…In our laboratory, research efforts have concentrated on synthesizing quinazoline derivatives with substituted moieties having high lipophilic properties in the hope of developing effective and safe compounds [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Herein, we report the crystal structure of 6-iodo-3-phenyl-2-propylquinazolin-4(3H)-one as a methaqualone analogue.…”
“…Quinazolinones were considered to be a scaffold with potential biological activities. Besides possessing a variety of biological effects including antimicrobial [1][2][3][4][5][6], anticonvulsant [7,8], and antihistamine [9,10] activities, compounds containing quinazolin-4-one nucleus also showed promising anticancer potency [11][12][13][14][15][16][17][18][19][20]. Along with that, 5-arylidene-2thioxothiazolidine-4-one compounds are an important class of compounds with a wide range of pharmaceutical properties.…”
Ethyl 2-((4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)acetate (3) which was synthesized starting from anthranilic acid (1) via 2-thioxo-3-phenylquinazolin-4(3H)-one (2) reacted with hydrazine hydrate to afford 2-((4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)acetohydrazide (4). Reaction of (4) with thiocarbonyl-bis-thioglycolic acid gave a new compound name N-(4-oxo-2-thioxothiazolidin-3-yl)-2-((4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)acetamide (5). Knoevenagel condensation of (5) with appropriate aldehydes gave fourteen (Z)-N-(5-arylidene-4-oxo-2-thioxothiazolidin-3-yl)-2-((4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)acetamide compounds (6a–o) with moderate yield. The chemical structure of the compounds was elucidated on the basis of IR, 1H-NMR, 13C-NMR, and HR-MS spectral data. The 5-arylidene-2-thioxothiazolidinone compounds exhibited mild-to-moderate cytotoxic activity against both K562 (chronic myelogenous leukemia) cells and MCF7 (breast cancer) cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
