title: S- and C-nucleosidoquinazoline as new nucleoside analogs with potential analgesic and anti-inflammatory activity.
abstract: Thioglycosides and C-glycosides have received considerable attention, because they are widely employed as biological inhibitors, inducers and ligands for affinity chromatography of carbohydrate-processing enzymes and proteins. Moreover, they are promising candidates in synthetic carbohydrate chemistry as convenient and versatile glycosyl donors. Among these glycosyl donors are the thioglycosyl and N-glycosyl heterocycles that are sufficiently stable under a variety of reaction conditions and have the ability to be readily converted into a variety of other functionalities. We report here, the synthesis of 2-thioxo-quinazolines 1a-c which were used as a base to the synthesis of S-nucleoside of types 10, 11 and acyclic C-nucleoside analogs of type 14 and their analgesic and anti-inflammatory activities were evaluated giving good results.
