(verify) Normorphine is an opiate analogue that is derived from the N-demethylated derivative of morphine first described in the 1950s[1] when a large group of N-substituted morphine analogues were characterized for activity.
Normorphine has relatively little opioid activity in its own right,[2][3] but is a useful intermediate which can be used to produce both opioid antagonists such as nalorphine, and also potent opioid agonists such as N-phenethylnormorphine.[4] It is also produced as a major metabolite of morphine,[5] with its formation from morphine catalysed by the liver enzymes CYP3A4 and CYP2C8.[6]
