Hybrid Docking-QSAR Studies of 1, 4-dihydropyridine-3, 5-Dicarboxamides as Potential Antitubercular Agents.

BACKGROUND: Tuberculosis is one of the main medical problems and some people are suffering still from this infectious disease. 1, 4-dihydropyridines are multi-target ligands that recently are recognized as anti-tubercular agents. METHODS: In the current research, computational studies were conducted of some synthesized 1, 4- dihydropyridine-3, 5-dicarboxamides in non-hydrolyzed and hydrolyzed forms to find the drugreceptor interactions profile. RESULTS: Among equations obtained for non-hydrolyzed compounds, the model with better statistical parameters such as R2= 0.9462, q2 of LOO= 0.8318 and q2 of LMO= 0.7987 was considered as the best one and EEig08d, LAI, Mor23m, GATS3e, Mor28m descriptors were identified as the most significant factors that affect the biological activity of non-hydrolyzed compounds. CONCLUSION: In the hydrolyzed compounds, the model which has R2= 0.9731, q2 of LOO= 0.91154462 and q2 of LMO= 0.742 was considered as the best one and Mor27e and BEHv2 were also revealed as the most important descriptors in hydrolyzed compounds.

Anticonvulsant Effects of New 1, 4-DihydropyridineDerivatives Containing Imidazolyl Moiety Against Seizures Induced by Pentylenetetrazole and Maximal Electroshock in Mice.

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 this paper, anticonvulsant screening of 10 synthesized new derivatives of 1, 4-dihydropyridine-3, 5-dicarboxamides was performed. Anticonvulsant activity was evaluated by intravenous and intraperitoneal pentylenetetrazole and maximal electroshock induced seizures tests. Nifedipine was used as reference drug. Our pharmacological results revealing the compounds 2, 4, 5, and 6 can be effective in both absence and grandmal seizures in human. These pharmacological studies have displayed that these new dihydropyridine derivatives are capable to inhibiting seizures induced by pentylenetetrazole and maximal electroshock in mice efficiently.
