Synthesis and biological evaluation of some 6-arylamidomorphines as analogues of morphine-6-glucuronide.
A series of 6-beta-arylamidomorphines was synthesized and biologically evaluated. Various aryl substituents were introduced into the arylamidomorphines to examine substituent structure-activity relationships. Competition binding assays showed that compounds 10a-h bound to the mu opioid receptor with high affinity (0.2-0.6 nM). Functional assays showed that compounds 10a-h acted as full mu opioid receptor agonists. The ED(50) of compound 10e.HCl as an analgesic was 12.6 mg/kg in the tail flick latency test in the rat.
