CJ-15208

Description

CJ-15208 is a potent and selective ?-opioid receptor antagonist with significant opioid activity. CJ-15208 exhibited strong analgesic effects in the warm water tail withdrawal test in mice and was mediated through multiple opioid receptors. The stereoisomers of CJ-15208 exhibited different opioid activity characteristics, for example, one stereoisomer exhibited ?-opioid receptor antagonism, while the other exhibited ?-opioid receptor antagonism. All stereoisomers of CJ-15208 had no significant effects on respiration. The stereoisomers of CJ-15208 did not lead to the development of drug tolerance, which makes it potential in the further development of safe opioid analgesics.
