Anticonvulsant and antitubercular activities of 6-Phenyl/Biphenyl-4-yl-2- [2-(pyridin-2-ylamino)-ethyl]-and 6-(Biphenyl-4yl)-2-(2N-subtituted amin-1-yl)-ethyl derivatives of 4,5-dihydropyridazin-3(2H)-one

Some 6-Phenyl/Biphenyl-4-yl-2-[2-(pyridin-2-ylamino)-ethyl]/-2-(2N- subtituted amin-1-yl)-ethyl-4,5- dihydropyridazin-3(2H)-one (4a-h) were synthesized by reacting 6-phenyl/biphenyl-4,5-dihydropyridazin-3(2H)-one with bromoethyl derivatives of cyclic secondary amines and 2-aminopyridine. All the compounds, 4a-h, were evaluated as anticonvulsant by using maximum electro shock (MES) and isoniazid (INH) induced convulsion methods at 50mg/kg dose level, and as antitubercular by Microplate Almar Blue Assay (MABA) method. In anticonvulsant activity, phenytoin (25mg/kg) and sodium vaproate (50mg/kg) were used as reference drugs. All compounds (4a-h) showed significant anticonvulsant activities against both MES and INH methods, and compound g showed highest activity against MES method. In antitubercular activity, compounds 4c-4h showed 25 μg/ml MIC value, and compounds 4a-4b exhibited 50 μg/ml MIC value when compared with reference drugs [isoniazid (3.125 μg/ml), pyrizinamide (3.125μg/ml)] and (streptomycin 6.25μg/ml) MIC values, and found less potent than the reference drugs.

Page/Page column 10-11, (2010/04/25)
The present invention relates to novel imidazolium compounds and improved method for the preparation of imidazolium salts. More specifically the invention describes preparation of 1,3-substituted imidazolium reagents whereby the reactive species can be regenerated upon consumption and readily re-usable for versatile chemical transformations. The syntheses of novel imidazolium salts are for applications as oxidizing agent in environmentally electrochemical reactions, internal electrolyte for durable reference electrode and lipophilic salts for anion chemical sensors.
