Opiate is properly limited to the natural alkaloids found in the resin of the opium poppy although some include semi-synthetic derivatives. [24] [25] Other opioids are semi-synthetic and synthetic drugs such as hydrocodone, oxycodone, and fentanyl; antagonist drugs such as naloxone; and endogenous peptides such as endorphins. [26]
Morphinan is the prototype chemical structure of a large chemical class of psychoactive drugs, consisting of opiate analgesics, cough suppressants, and dissociative hallucinogens, among others. Typical examples include compounds such as morphine, codeine, and dextromethorphan (DXM).
Dihydromorphine is a moderately strong analgesic and is used clinically in the treatment of pain and also is an active metabolite of the analgesic opioid drug dihydrocodeine. [ 3 ] [ 4 ] [ 5 ] Dihydromorphine occurs in trace quantities in assays of opium on occasion, as does dihydrocodeine, dihydrothebaine, tetrahydrothebaine, etc.
One representative example is the New Zealand provisions enacted in 1988 in response to the first wave of fentanyl derivatives. This bans a set of structures as follows; "Fentanyl analogues, in which the N-[1-(2-phenethyl)-4-piperidyl]aniline nucleus has additional radicals, either alone or in combination, attached as follows:
A chart outlining the structural features that define opiates and opioids, including distinctions between semi-synthetic and fully synthetic opioid structures. An opiate is an alkaloid substance derived from opium (or poppy straw). [1]
The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
