IMIDAZOLIN DERIVATIVES AND A METHOD FOR PRODUCING THE SAME AND A THERAPEUTIC AGENT FOR MAINTAINING BLOOD PRESSURE

摘要

(1) The imidazoline derivative represented by the following general formula (1) (see fig. I) where R1 is a substituent endowed with water solubility or fat solubility, particularly carboxyl group or carboxymethoxy group or a pharmaceutically acceptable salt thereof, (2) The method for producing the above-mentioned compound, and (3) A therapeutic agent containing as its active ingredient the above-mentioned imidazoline derivative or an imidazoline derivative wherein R1 indicated in the formula (1) is hydrogen atom. The imidazoline derivative set forth under (1) above is a novel substance; and this compound itself and its derivative having R1 as indicated in the general formula (1) is hydrogen atom are useful as a therapeutic agent for treatment of shock from the fall in blood pressure by virtue of their ability to remove excess NO which is the vascular endothelium-derived relaxing factor (EDRF).
