Dinucleosides containing a thiazolidin-4-one linkage were prepared by one-pot tandem Staudinger/aza-Wittig/intermolecular cyclization under microwave irradiation and their structures were confirmed. Preliminary examination of HIV-RT inhibition showed that the dinucleosides containing (R)-thiazolidin-4-one linkage are significantly more active than those containing (S)-thiazolidin-4-one linkage.

A series of novel 2-(substitutedphenyl)-5-methyl-3-(phenylamino)-1,3-thiazolidin-4-ones (4a-g) were synthesized and structurally confirmed by elemental, IR, H NMR and MS spectral analysis. Further, the antiviral screening of 2-(substitutedphenyl)-5-methyl-3-(phenylamino)-1,3-thiazolidin-4-ones (4a-g) against a broad panel of DNA and RNA viral strains indicated that 2-(4-chlorophenyl)-5-methyl-3...

ABSTRACT. A series of 2-(4-substituted-phenylimino)thiazolidin-4-one compounds was synthesized via heterocyclizing the corresponding N-aryl-2-chloroacetamides with ammonium thiocyanate. Their chemical structures were elucidated based on an extensive analysis their spectroscopic data, including infrared, 1H NMR, 13C and mass analyses. The possible tautomeric forms thiazolidine-4-ones studied. ta...

Thiazacridine and imidazacridine derivatives have shown promising results as tumors suppressors in some cancer cell lines. For a better understanding of the mechanism of action of these compounds, binding studies of 5-acridin-9-ylmethylidene-3-amino-2-thioxo-thiazolidin-4-one, 5-acridin-9-ylmethylidene-2-thioxo-thiazolidin-4-one, 5-acridin-9-ylmethylidene-2-thioxo-imidazolidin-4-one and 3-acrid...
