摘要:
Dihydrocaffeic acid derivatives are disclosed which are applicable as medicines having excellent absorbency in the case of oral administration and good concentration retention in blood. The disclosed compounds have the function to induce the production and secretion of a nerve growth factor (NGF) in the brain tissue, and accordingly are effective as medicines for inhibiting the progression of regressive disorders of the central nervous system and for the therapeutic treatment of such disorders.
摘要:
The present invention relates to a novel (-)-2-pyrazoline compound and therapeutic agents containing the same as an effective ingredient; furthermore, it relates to a method for optically resolving 1-(3-pyridylcarbonyl)-methyl-2-pyrazoline.
摘要:
This invention relates to new 2-pyrazoline derivatives represented by the following general formula (A): ( wherein R¹ denotes a pyridyl, a pyrazyl or an alkoxyl group; and R² stands for hydrogen atom, an alkyl, a pyridyl, a furyl, phenyl or a substituted phenyl group ), and to a process for producing the same. This invention also relates to agents for treating cerebrovascular diseases containing, as active ingredients, a 2-pyrazoline derivative represented by the following general formula (G): ( wherein R³ denotes hydrogen atom, an alkyl, acetyl, an alkoxycarbonyl, an amino, benzoyl, a substituted benzoyl, a pyridylcarbonyl, a furylcabonyl, a thienylcarbonyl, a pyrazylcarbonyl, an N-substituted carbamoyl, an N-substituted thiocarbamoyl, or carboxyl group; and R⁴ stands for hydrogen atom, an alkyl, a pyridyl, a thienyl, a furyl, cyclohexyl, phenyl or a substituted phenyl group ) or a pharmaceutically acceptable salt thereof. Administration of an agent of this invention for treating cerebrovascular diseases copes with cerebral edemata in the acute stage of cerebral apoplexy and regulates the whole-body and intracranial blood circulation, thereby protecting ischemic lesions and minimizing the spread of affected parts.
