The anticonvulsant study of 25 newly synthesized quinazolin-4(3H)-one substituted 1H and 2H-tetrazoles (6a–6d, 7a–7b, 8a–8i, 8a′–8i′) was executed. The study employing the maximal electroshock and subcutaneous pentylenetetrazole (scPTZ) screens, the ‘gold standards’ in the preliminary anticonvulsant breakthrough and the neurotoxicity study applying the rotorod test unveiled a triad of compounds 6c, 7b and 8i′ as the looms amongst the compendium of synthesized compounds. The quantification data of these compounds following oral administration in rats showcased 7b to endorse a remarkable position in the MES screen with a protective indice (PI) of >39.67 and 6c in the scPTZ delineating a PI > 3.10, respectively. All the potent compounds were destitute of toxicity.
