In preclinical studies, CR665 was highly selective for the peripheral kappa opioid receptor. Preclinical animal studies suggest that CR665 is a potent analgesic compound. In addition, unlike currently marketed opioids, CR665 does not produce inhibition of intestinal transit (ileus), induce respiratory depression, or elicit signs of euphoria or addiction in animal models. Preclinical studies also indicate that CR665 possesses anti-inflammatory activities."}]
