title: Synthesis and anti-inflammatory activity of some novel biphenyl-4-carboxylic acid 5-(arylidene)-2-(aryl)-4-oxothiazolidin-3-yl amides.
abstract: Some new biphenyl-4-carboxylic acid 5-(arylidene)-2-(aryl)-4-oxothiazolidin-3-yl amides have been synthesized and evaluated for anti-inflammatory activity. Biphenyl-4-carboxylic acid hydrazide was converted to the corresponding aryl hydrazones using aryl aldehydes in the presence of catalytic amount of glacial acetic acid. The aryl hydrazones on reaction with thioglycolic acid in the presence of anhydrous zinc chloride yielded the biphenyl-4-carboxylic acid 2-(aryl)-4-oxothiazolidin-3-yl amides, which again on reaction with aromatic aldehydes in the presence of anhydrous sodium acetate and glacial acetic acid furnished the title compounds. The structures of all these newly synthesized compounds were confirmed by their analytical and spectral data which were in full agreement with proposed structures. All compounds were screened for anti-inflammatory activity employing carrageenan test at the dose of 10 mg/kg and exhibited significant activities.
