Abstract
A series of aryl acid hydrazones of substituted aromatic acid hydrazides (D1 to D20) were synthesised and evaluated for anticonvulsant activity. Aryl acid hydrazones of Nicotinic acid hydrazide (D8, D9, and D10) have displayed excellent protection in maximal electroshock screen. These compounds have also exhibited excellent binding properties with Lys 329 residue of gamma amino butyrate amino transferase (GABA-AT) in Lamarckian genetic algorithm based flexible docking studies. Compound D8, N1-(4-chlorobenzylidene) nicotinohydrazide was found to be the most potent analog with ED50 value of 16.1 mg/kg and protective index (PI = TD50/ED50) value of >20, which was much greater than that of the prototype drug phenytoin (PI = 6.9). It has shown free binding energy value of −10.20 kcal/mol and inhibition constant (Ki) value of 33.30 nM for GABA-AT, indicating that aryl acid hydrazones of nicotinic acid hydrazide could be considered as a new pharmacophore in the design of novel anticonvulsant drugs.
