They are also referred to as μ(mu)-opioid peptide (MOP) receptors. The prototypical μ-opioid receptor agonist is morphine, the primary psychoactive alkaloid in opium and for which the receptor was named, with mu being the first letter of Morpheus, the compound's namesake in the original Greek.
7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa, commonly known as kratom. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
This analgesic effect has been studied in animals and shown to be reversible by naloxone, suggesting a mu opioid receptor mediated effect. [ 2 ] [ 3 ] Subsequent research has identified several active alkaloids in the plant, [ 4 ] [ 5 ] the most important of which are hodgkinsine , which acts as both a mu-opioid agonist and NMDA antagonist ...
An opiate, in classical pharmacology, is a substance derived from opium. In more modern usage, the term opioid is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists). Opiates are alkaloid compounds naturally found in the Papaver somniferum plant (opium poppy).
Matrine can be commercially extracted from the traditional Chinese medical herb Sophora flavescens Ait. Mu opioid agonism is associated with euphoria, while kappa opioid agonism is associated with dysphoria and psychotomimetic hallucinations (as seen in the kappa-agonist Salvinorin A). Both receptors are known to produce analgesia when activated.
