Benzofurans are very interesting heterocycles, which are available in nature and show a wide range of pharmacological activities. Hence, different benzofurans having 4-thiazolidinones have been synthesized for the purpose of pharmacological evaluation. The desired compounds were prepared using simple starting materials like salicylaldehyde and ethyl bromoacetate. The reaction between these comp...

The aim of the present work was to synthesise coumarinyl heterocycles and to elucidate the potential role of these compounds as antioxidants and cytotoxic agents against Dalton's lymphoma ascites tumour cells (DLA) and Ehrlich ascites carcinoma cells (EAC). The synthesis of coumarin derivatives containing pyrazole, pyrazolone, thiazolidin-4-one, 5-carboxymethyl-4-thiazolidinone and 3-acetyl-1,3...

A series of new 2-arylimino-3-aryl-5-[5?-(3,4-dichlorophenyl)-2?-furylidene]-4-thiazolidinones (3a-l) have been synthesised by the condensation of 5-(3,4-dichlorophenyl)-2-furaldehyde 1 with 2-arylimino-3-aryl-5H-4-thiazolidinones 2 in glacial acetic acid. The physical and spectral data of the synthesised compounds are determined. The synthesised compounds have been screened for their in vitro ...

Novel 11-substituted 3,11-dihydro-2H-benzo[6,7]thiochromeno[2,3-d][1,3]-thiazole-2,5,10-triones 4a-i were synthesized in 75-90% yields via the hetero-Diels-Alder reaction of 5-arylidene-4-thioxo-2-thiazolidinones with 1,4-naphthoquinone. The synthesized compounds were evaluated for their antineoplastic and antimycobacterial activities. A moderate selectivity against melanoma cancer cells (GI50 ...

Condensation of 4-amino-2,3-dimethyl-1-phenyl-3-pyrazoline-5-one with different aromatic and heterocyclic aldehydes in dry toluene give schiff bases 3(a-g), which on reaction with thioglycolic acid and thiolactic acid in dry toluene give the corresponding 2,3-disubstituted-4-thiazolidinones 4(a-g) and 2,3-disubstituted-5-methyl-4thiazolidinones 5(a-g). The methylene carbon atom at the position ...
