- New derivatives of hydantoin as potential antiproliferative agents: Biological and structural characterization in combination with quantum chemical calculations
-
Two new series of hydantoin derivatives, 3-(4-substituted benzyl)-5,5-diphenyl- and 3-(4-substituted benzyl)-5-ethyl-5-phenylhydantoins, were synthesized and their antiproliferative activity was tested against human colon cancer HCT-116 and breast cancer

- Solvent effects on the structure-property relationship of some potentially pharmacologically active 3-(4-substituted benzyl)-5-ethyl-5-phenyl- and 3-(4-substituted benzyl)-5,5-diphenylhydantoins
-
Two series of 3-(4-substituted benzyl)-5-ethyl-5-phenyl- and 3-(4-substituted benzyl)-5,5-diphenylhydantoins were synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions on the spectral shifts were analyzed by means of the linear solvation energy relationship (LSER) methodology of Kamlet and Taft. The quantitative relationships between hydrogen bonding interactions and the lipophilicity and blood-brain permeation of the studied compounds were discussed. Satisfactory linear dependences were obtained for moderate electron-donating and electron-withdrawing substituents at the benzyl moiety, while the strong electron-withdrawing substituent (NO2) significantly modifies the solvation characteristics of the molecule. The paper clearly demonstrates how the solvatochromic comparison method may be applied to estimate the contributions of various modes of solvation to the pharmaceutically relevant properties of these newly synthetized hydantoin derivatives.

- Preparation of hydantoins by catalytic oxidative carbonylation of α-amino amides
-
(Chemical Equation Presented) Hydantoins can be synthesized from the corresponding amino amides employing oxidative catalytic carbonylation using W(CO)6 as the catalyst, I2 as the oxidant,COas the carbonyl source, andDBUas base. Secondary amides afford the hydantoins in good to excellent yields, which decrease as the steric bulk of the N-alkyl substituent increases. 2009 American Chemical Society.

- Solvent effects on the structure-activity relationship of phenytoin-like anticonvulsant drugs
-
The absorption spectra of nine compounds structurally related to phenytoin (5,5-diphenylhydantoin) were recorded in twelve solvents over the range of 200 to 400 nm. The effects of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions were analyzed by means of the linear solvation energy relationship (LSER) concept proposed by Kamlet and Taft. The lipophilic activity of the investigated hydantoins was estimated by calculation of their log 10 P values. The calculated values of log 10 P were correlated with the ratio of the contributions of specific and non-specific solute/solvent interactions. The correlation equations were combined with the corresponding ED50 values to generate new equations that demonstrate exact relationship between solute/solvent interactions and the structure-activity parameters.

- Versatile access to benzhydryl-phenylureas through an unexpected rearrangement during microwave-enhanced synthesis of hydantoins
-
(Equation presented) A new access to benzhydryl-phenylureas is described. These new interesting urea derivatives were obtained by reaction of substituted benzils with substituted phenylureas under microwave irradiation. Phenylthiourea, when reacted with benzil, gave 3-phenyl-thiohydantoin. Moreover, benzylurea, as phenethylurea, gave the corresponding 3-substituted hydantoin derivatives, demonstrating that only phenylurea derivatives can result in benzhydryl-phenylureas under the applied conditions. This new reaction proved to be an easy access to substituted 1-benzhydryl-3-phenyl-ureas.

- 3-alkyl-(5,5'-diphenyl)imidazolidinediones as new cannabinoid receptor ligands
-
Twenty-four 3-alkyl-(5,5'-diphenyl)imidazolidinediones were synthesized and evaluated as new cannabinoid receptor ligands. Three compounds exhibited a Ki value around 100 nM against [3H]-SR 141716A binding obtained from human CB1 transfected CHO cells membranes. The lack of change of affinity in the presence of a non hydrolyzable GTP analogue seems to indicate they are cannabinoid antagonists.

- Solid phase synthesis of hydantoins using a carbamate linker and a novel cyclization/cleavage step
-
An 800 compound hydantoin library has been constructed using a diverse set of 20 amino acids and over 80 primary amines. Amino acids were attached via their N-termini to hydroxymethyl polystyrene using a carbamate linker. Bound amino acids were converted to their corresponding amides and then cyclized under basic conditions to give hydantoins in high purities.
