A protocol for the palladium(0)-catalyzed amidation of heteroaromatic tosylates was successfully developed. The methodology proved to be effective for a variety of heteroaryl tosylates including the pyridine, pyrimidine, quinoline and quinoxaline ring systems. Successful carbon-nitrogen bond formation with these heteroaryl
A series of peptide-based transition-state human neutrophil elastase (HNE) inhibitors with N-terminal acidic moieties were synthesized and their inhibitory activity against HNE was evaluated both in vitro and in vivo. Our results show that compounds containing cyclic amide bridged acidic
Novel series of 1-(arenesulfonyl)imidazolidin-2-one (3a-i) and 1,3-bis(arenesulfonyl)imidazolidin-2-one (5a-i) have been synthesized and tested for their antitumor activity against 60 tumor cell lines taken from nine different organs. A significant inhibition for cancer cells was observed with series 5a-i compounds compared
The synthesis and the physico-chemical properties of four 3-(4-bromophenacyl)-5-arylidene-thiazolidine-2,4-diones, two 3-(4-bromobenzyl)-5-arylidene-thiazolidine-2,4-diones and seven 3-(4-chlorobenzyl)-5-arylidene-4-thio-imidazolidine-2-ones were described. These products were synthetized by the aldolisation-crotonisation reaction between aromatic aldehydes and substituted thiazolidinediones or thio-imidazolidinones.

An efficient and versatile synthesis of novel exo-imidazolidin-2-one dienes is described. This involves the base-assisted condensation/cyclization cascade reaction of the monoimino derivatives of diacetyl with a series of isocyanates. This methodology enables preparation of symmetrical dienes, as long as the
