Design and evaluation of non-carboxylate 5-arylidene-2-thioxo-4-imidazolidinones as novel non-competitive inhibitors of protein tyrosine phosphatase 1B
Proteintyrosinephosphatase 1B (PTP1B) acts as a negative regulator of insulin and leptin signalling and is crucially involved in the development of type 2 diabetes mellitus, obesity, cancer and neurodegenerative diseases. Pursuing our efforts to identify PTP1B inhibitors endowed with drug-like properties, we designed and evaluated 3-aryl-5-arylidene-2-thioxo-4-imidazolidinones (7) as a novel class

An efficient, microwave-assisted method for the liquid-phase combinatorial synthesis of 3,5-disubstituted-thiohydantoin has been developed. Fmoc-protected amino acids were coupled with HO-PEG-OH and after deprotection, reacted with various isothiocyanates in microwave cavity. The PEG bound thiourea compounds underwent base mediated cyclization/cleavage step by microwave flash heating. The desired products were then liberated from the soluble matrix in good yield and purity under microwave exposure. (C) 2003 Elsevier Ltd. All rights reserved.
Three types of copper derivatives formed by CuCl<sub>2</sub>·2H<sub>2</sub>O interaction with (<i>Z</i>)-3-aryl-2-(methylthio)-5-(pyridine-2-ylmethylene)-3,5-dihydro-4<i>H</i>-imidazol-4-ones
presence of a reducing solvent (alcohol or dimethylformamide (DMF)) produce three types of Cu-containing compounds: two Cu complexes with a composition of CuII(3)Cl2 (4) and CuI(3)Cl (5) as well as a salt (3 + H)+CuICl2− (6) in a 4 : 5 : 6 ratio depending on the substituent at the N(3) nitrogen atom of the ligand moiety. In non-reducing solvents (dimethylsulfoxide (DMSO) and CHCl3/acetone), only complexes
