title: Synthesis of N-aryl-N'-[2-phenyl-3-quinazoline(3H)-4-one] acylthiourea derivatives as anticonvulsants.
abstract: By the reaction of [2-phenyl-3-quinazolineo (3H)-4-one] acyl isothiocynates and appropriate aryl amines in acetone, 24 new compounds, having a substituted thiourea grouping at the 3-position of the quianozolone moiety, were prepared. All compounds, except two, showed different degree of protection against pentetrazol induced seizures test in albino mice. While studying the effect of structural variation no definite pattern could be observed due to variations in 1-aryl moiety, but it was noticed that generally the branching or lengthening of 3-acyl chain either diminishes or does not effect the activity.
