ABSTRACT:
2-Pyrazoline derivatives of the formula (A): ##STR1## where R.sup.1 is a pyridyl, a pyrazyl or an alkoxyl group; and R.sup.2 is a hydrogen atom, an alkyl, a pyridyl, a furyl, phenyl or a substituted phenyl group, and to a process for producing the same. Therapeutic agents for treating cerebrovascular diseases containing, as the active ingredient, a 2-pyrazoline derivative represented by the formula (G): ##STR2## where R.sup.3 is a hydrogen atom, an alkyl, acetyl, an alkoxycarbonyl, an amino, benzoyl, a substituted benzoyl, a pyridylcarbonyl, a furylcabonyl, a thienylcarbonyl, a pyrazylocarbonyl, an N-substituted carbamoyl, an N-substituted thiocarbamoyl, or carboxyl group; and R.sup.4 is a hydrogen atom, an alkyl, a pyridyl, a thienyl, a furyl, cyclohexyl, phenyl or a substituted phenyl group or a pharmaceutically acceptable salt thereof. These therapeutic agents cope with cerebral edemas in the acute stage of cerebral apoplexy and regulates the whole-body and intracranial body circulation, thereby protecting ischemic lesions and minimizing the spread to affected parts.
