Abstract
Several 5‐alkoxy‐tetrazolo[1,5‐a]quinazoline derivatives have been synthesized by reacting 2,4‐dichloroquinazoline with various phenols or aliphatic alcohol and then with sodium azide. The structures of these compounds have been confirmed by IR, MS, 1H‐NMR, and elementary analysis. Anticonvulsant activities were evaluated using the maximal electroshock (MES) test. Most of the synthesized compounds displayed weak anticonvulsant activity at a dose of 300 mg/kg. Antidepressant activities were investigated by forced swimming test. Two compounds, namely 5‐(hexyloxy)tetrazolo[1,5‐a]quinazoline and 5‐(4‐methoxyphenoxy)tetrazolo[1,5‐a]quinazoline, showed significant antidepressant activity, which decreased the immobility time by 62.2 and 51.7% at 100 mg/kg dose level.Keywords
