In the present study on the development of new anticonvulsants, the library of differently substituted N-phenylamino pyrrolidine2,5-dione and hexahydro-isoindole-1,3-dione derivatives was synthesized. The anticonvulsant activity of all the compounds was evaluated using the maximal electroshock (MES) and pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotorod test. The pharmacological results revealed that the majority of compounds were effective in electrical (MES) and/or pentylenetetrazole induced seizure (scPTZ) models. The quantitative in vivo anticonvulsant evaluation of N-phenylamino-3,3-dimethyl-pyrrolidine-2,5-dione (15), conducted at the time of peak pharmacodynamic activity (TPE), showed the MES ED50 value of 69.89 mg/ kg in rats. The median toxic dose (TD50) was 500 mg/ kg, providing compound 15 with a protective index (TD50/ED50) of 7.15 in the MES test. (c) 2008 Elsevier Ltd. All rights reserved.

Conjugateaddition occurs efficiently from excited hydrazide based acrylanilides under both UV and metal free visible light irradiations. The reaction proceeds via an excited state encounter complex that bifurcates either via an electron or energy transfer pathway. The generality of excited state conjugateaddition is demonstrated using chloromethylation and by thiol addition.
