Here we describe the efficient synthesis of alkyl 4-arylsubstituted-6-chloro-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylates and 4-arylsubstituted-4,7-dihydro-furo[3,4-b]pyridine-2,5(1H,3H)-diones via microwave-accelerated reaction of alkyl 4-arylsubstituted-2-methyl-6-oxo-1,4,5,6-tetrahydro-3-pyridinecarboxylates with the appropriate reagents. This eco-friendly approach to these valuable ...

Aim. Dihydropyridine calcium channel blockers (CCB) are widely preferred for the treatment of hypertension for their efficacy, metabolic neutrality and low side effect profile. However pedal edema formation limits their usage. The aim of the present study is to evaluate the incidence of pedal edema formation with a different dihydropyridine CCB in hypertensive patients who developed pedal edema...

The reported structures of reaction products of enaminones with malononitrile in ethanolic piperidine are revised. A novel route to 2,3-dihydropyridazine-4-carboxylic acids 4a-c via reactions of 2-cyano-5-(dimethylamino)-5-arylpenta-2,4-dienamides 8a-c with nitrous acid or with benzenediazonium chloride is reported. Compounds 8a-c are converted to 1,2-dihydropyridine-3-carboxylic acid and 1,2-d...

Recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. In this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using Hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at C-3 and C-5 positions of the DHP ring.In addition, 4 (5)-chloro-2-methyl-5 (...

1,4 Dihydropyridines are very versatile compounds and have important role as therapeutic agents. The 1, 4 (1,4 DHPs) well known calcium channel blocker their use in treatment of cardiovascular diseases is common. These also to antimicrobial activities. N-heterocyclic represent framework for agricultural pharmaceutical industries. antibacterial antifungal Hence, the substituted 4- Dihydropyridin...

Epilepsy is a chronic disorder of the brain affecting around 50 million people in the world.Up to 30% of epileptic patients do not respond to available drugs and medical therapies. In thispaper, anticonvulsant screening of 10 synthesized new derivatives of 1, 4-dihydropyridine-3,5-dicarboxamides was performed.Anticonvulsant activity was evaluated by intravenous and intraperitoneal pentylenetetr...
