In this study, synthesis of 5-benzylidene thiobarbituric acid derivative has been described. The route of preparation involved the uses of thiobarbituric acid as starting material and treated with 4-dimethylaminobenzaldehyde compound to give required derivative. This compound was identified by spectroscopic methods; H NMR, FTIR and CHNS analysis and also by measuring its melting point. A theoretical investigation is performed using hybrid Beck model (B3LYP), ESP showed regular distribution of charge density of whole molecule when one of the two proton is removed from a-carbon, the ESP for HOMO electron density is heavily localized on a negative carbon, reflect the reactivity of thiobarbituric molecule and show it as highly effective nucleophile when act into nucleophilic substitution reactions.

A general and practical green chemistry route to the synthesis of 5-arylidenethiobarbituric acids is described from aromatic aldehydes and thiobarbituric acid under three different sets of reaction conditions: water without catalyst conditions, microwave irradiation, and grinding method using NH 4 OAc as a catalyst at room temperature.
Discovery of (<i>Z</i>)-5-(4-Methoxybenzylidene)thiazolidine-2,4-dione, a Readily Available and Orally Active Glitazone for the Treatment of Concanavalin A-Induced Acute Liver Injury of BALB/c Mice
that oral administration of 2g, 2h, 4f, or 6h decreases, most significantly for 4f, the serum levels of alanine aminotransaminase (ALT) and asparate aminotransaminase (AST) in ConA-induced acute livery injuryBALB/cmice. Histopathological evaluation liver sections confirmed 4f as a potent, orallyactive compound for hepatoprotective effects against ConA-induced acuteliverinjury in BALB/cmice.
