- Synthesis and anticonvulsant activity of some new 4-aryl-4-imidazoline-2-one derivatives
-
In this study, some new 4-aryl-4-imidazoline-2-one deriratives have been prepared by the reaction of potassium cyanate with some aminoethanone hydrochlorides. The structure of these compounds have been confirmed by UV, IR, 1H-NMR and elementary analysis. Their anticonvulsant activities were determined by maximal electroshock (MTS) and subcutaneous metrazol (scMet) tests according to the ADD (Antiepileptic Drug Development) programme Phase I. Neurotoxicity of the compounds was evaluated by rotarod test. While 2 of the compounds showed protection against ScMet induced seizures at 30 and 300 mg/kg dose levels, 3 of the compounds showed neurotoxicity.

- Formation of Thioamide Derivatives from Reactions of Isothiocyanates with Oxazol-2-amines
-
4-Substituted oxazol-2-amines react with isothiocyanates to give products having a thioamide function at C5.The reaction is considered to be an electrophilic process in competition with the usual reaction of the amino group with the isothiocyanate.The nature of the isothiocyanate and the type of substituent at C4 affect the amount of the thioamide product formed.Some chemical properties of the thioamides are also investigated.

- RECYCLIZATION REACTIONS. RECYCLIZATIONS OF 3-ACYLMETHYL-2,4-THIAZOLIDINEDIONES BY THE ACTION OF NUCLEOPHILES
-
Four directions were established and investigated in the recyclization of 3-acylmethyl-2,4-thiazolidinediones with the participation of the side chain at the cyclic nitrogen atom and the formation of substituted 2-imidazolones or 2-oxazolones (under the influence of ammonia or hydroxides respectively), 2,5-diarylpyrazines (under the influence of methylamine), 6-monosubstituted or 2,6-disubstituted 4,5-dihydro-1,2,4-triazin-3-ones, and 5-substituted 1-amino-2-imidazolones (under the influence of hydrazine and phenylhydrazine).The directions of recyclization with hydrazines are determined by the stereochemical configuration of the intermediate hydrazones; the E-hydrazones of 3-acylmethyl-2,4-thiazolidenediones are converted into 4,5-dihydro-1,2,4-triazin-3-ones, while the Z izomers are converted into 1-amino-2-imidazolones.
