Document Type and Number:
Japanese Patent JP4296345
Kind Code:
B2
Abstract:

To provide a κ-opioid receptor agonist composed of a 2-phenylbenzothazoline derivative.

The present invention relates to the κ-opioid receptor agonist composed of a compound containing a chemical structure represented by formula (I) [wherein R represents an alkyl group having an amino group as a substituent group; R1represents an acyl group] as a basic skeleton or its salts. Namely, it is important for expressing κ-opioid receptor agonist action to have an amino group as a substituent group on phenyl group of the 2-phenylbenzothiazoline and have an acyl group on a nitrogen atom of the 2-phenylbenzothiazoline.
