A concise approach for the transformation of various S-amino acids into the 5-alkyl-3-phenyl-2-thioxoimidazolidin-4-one heterocycles using phenylisothiocyanate is described. Phenylthiohydantoins of amino acid were synthesized at room temperature in Et3N/DMF-H2O with easy workup and excellent yields.

An efficient and simple way for synthesis of thiohydantoins is reported. In the absence of any additional catalysts, a series of thiohydantoins were synthesized with amino esters and isothiocyanates in aqueous medium under microwave irradiation. Excellent isolated yields (up to 98 %) were obtained under mild conditions.

N-(2-Aryl-1-chloro-2-oxoethyl) carboxamides react under mild conditions with thiourea, N-alkyl-and N-arylthioureas, and various N,N′-disubstituted thioureas, following the Hantzsch reaction scheme. The reactions are selective, and the resulting 2,5-diamin

A series of substituted (±)3,5-diphenyl-2-thioxoimidazolin-4-ones was synthesized in order to design new type-2 cyclooxygenase (COX-2) inhibitors. This study has led to molecules which completely inhibit human recombinant COX-2 at 50 μM. Molecular modelli

The demonstration of the essential role of fatty acid amide hydrolase (FAAH) in hydrolyzing endogenous bioactive fatty acid derivatives has launched the quest for the discovery of inhibitors for this enzyme. Along this line, a set of 58 imidazolidine-2,4-dione and 2-thioxoimidazolidin-4-one derivatives was evaluated as FAAH inhibitors. Among these compounds, 3-substituted 5,5′-diphenylimidazolidine-2,4-dione and 3-substituted 5,5′-diphenyl-2-thioxoimidazolidin-4-one derivatives were previously described as CB1 cannabinoid receptor ligands. In the present study, we synthesized several derivatives exhibiting interesting FAAH inhibitory activity and devoid of affinity for the CB1 and CB2 cannabinoid receptors. For instance, 3-heptyl-5,5′-diphenylimidazolidine- 2,4-dione (14) and 5,5′-diphenyl-3-tetradecyl-2-thioxo-imidazolidin-4-one (46) showed p/50 values of 5.12 and 5.94, respectively. In conclusion, it appears that even though several 3-substituted 5,5′-diphenyl-2-thioxoimidazolidin-4-one and 3-substituted 5,5′-diphenylimidazolidine-2,4-dione derivatives have been previously shown to behave as CB1 cannabinoid receptor ligands, appropriate substitutions of these templates can result in FAAH inhibitors devoid of affinity for the cannabinoid receptors.
