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]

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.
Heroin, the common name for diacetylmorphine, is the first of several semi-synthetic opioids to be derived from morphine, a component of natural opium. [16] It is formed by the acetylation of morphine in order to increase the lipid solubility. [17]
Oxycodone, a semi-synthetic opioid, is a highly selective full agonist of the μ-opioid receptor (MOR). [40] [41] This is the main biological target of the endogenous opioid neuropeptide β-endorphin. [18] Oxycodone has low affinity for the δ-opioid receptor (DOR) and the κ-opioid receptor (KOR), where it is an agonist similarly.
The primary three are morphine, codeine, and thebaine (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone or hydrocodone). Legally speaking, the term "narcotic" may be imprecisely defined and typically has negative connotations.
[citation needed] The Norman strain of P. somniferum, also developed in Tasmania, produces down to 0.04% morphine but with much higher amounts of thebaine and oripavine, which can be used to synthesise semi-synthetic opioids as well as other drugs like stimulants, emetics, opioid antagonists, anticholinergics, and smooth-muscle agents.
