identified as a lead target structure for the development of particularly effective compounds targeting Burkitt's lymphoma (BL). OBJECTIVES The aims of the curent study were to synthesise a panel of nitrostyrene compounds and to evaluate their activity in Burkitt's lymphoma (BL). METHODS A panel of structurally varied compounds were designed and synthesised using Henry Knoevenagel condensation reactions.
compounds. In particular thiazolidines are known to show anti-inflammatory activity. With reference to this, synthesis of some 5-benzylidene-thioxoimidazolidinones and thioxothiazolidinones substituted at the position 3 by a benzyl (or phenacyl) group, were reported in previous papers [3-5]. Synthesis and physicochemical data of new 5-benzylidene-3-(4-chlorobenzyl)thiazolidine-2,4-diones 8-10 or 5-(l//
A novel set of acridinylidene thiazolidinediones and benzylidene thiazolidinediones was synthesized by nucleophilic addition of cyanoacrylates. Some of these compounds were evaluated for their glucose lowering capability and their effects on the triglyceride level in alloxan diabetic mice. (c) 2005 Elsevier SAS. All rights reserved.

Eight new 5-arylidene-3-benzyl-thiazolidine-2,4-diones with halide groups on their benzyl rings were synthesized and assayed in vivo to investigate their anti-inflammatory activities. These compounds showed considerable biological efficacy when compared to rosiglitazone, a potent and well-known agonist of PPAR gamma, which was used as a reference drug. This suggests that the substituted 5-arylidene and 3-benzylidene groups play important roles in the anti-inflammatory properties of this class of compounds. Docking studies with these compounds indicated that they exhibit specific interactions with key residues located in the site of the PPAR gamma structure, which corroborates the hypothesis that these molecules are potential ligands of PPAR gamma. In addition, competition binding assays showed that four of these compounds bound directly to the ligand-binding domain of PPAR gamma, with reduced affinity when compared to rosiglitazone. An important trend was observed between the docking scores and the anti-inflammatory activities of this set of molecules. The analysis of the docking results, which takes into account the hydrophilic and hydrophobic interactions between the ligands and the target, explained why the 3-(2-bromobenzyl)-5-(4-methanesulfonyl-benzylidene)-thiazolidine-2,4-dione compound had the best activity and the best docking score. Almost all of the stronger hydrophilic interactions occurred between the substituted 5-arylidene group of this compound and the residues of the binding site. (C) 2010 Elsevier Ltd.
