Enadoline is a drug which acts as a highly selective κ-opioid agonist. In human studies, it produced visual distortions and feelings of dissociation, reminiscent of the effects of salvinorin A. It was studied as a potential analgesic, but abandoned because of the dose-limiting effects of dysphoria, which could be expected from a κ-opioid agonist.
Salvinorin A (83729-01-5)
Salvinorin A is the main active psychotropic molecule in Salvia divinorum, a Mexican plant which has a long history of use as an entheogen by indigenous Mazatec shamans. Salvinorin A is considered a dissociative. It is structurally distinct from other naturally occurring hallucinogens (such as DMT, psilocybin, and mescaline) because it contains no nitrogen atoms; hence, it is not an alkaloid (and cannot be rendered as a salt) but a terpenoid.
Asimadoline (EMD-61753) is a drug which acts as a peripherally selective κ-opioid receptor (KOR) agonist. Because of its poor ability to cross the blood–brain barrier, asimadoline lacks the psychotomimetic effects of centrally acting KOR agonists, and consequently has more potential for medical use, and has been researched as a possible treatment for irritable bowel syndrome, with reasonable efficacy seen in clinical trials.
Spiradoline (U-62066) is a drug which acts as a highly selective κ-opioid agonist. It has analgesic, diuretic and antitussive effects, and produces subjective effects in animals similar to those of ketazocine and alazocine. The main effect in humans is sedation, along with analgesic and diuretic effects, but significant side effects such as dysphoria and hallucinations have stopped it from being used clinically.
U-69,593 is a drug which acts as a potent and selective κ1-opioid receptor agonist. In animal studies it has been shown to produce antinociception, anti-inflammation, anxiolysis (at low doses), respiratory depression, and diuresis, while having little effect on gastrointestinal motility. It also inhibits the peripheral, though not central secretion of oxytocin and vasopressin in rats.

Tifluadom is a benzodiazepine derivative with an unusual activity profile. Unlike most benzodiazepines, tifluadom has no activity at the GABAA receptor, but instead is a selective agonist for the κ-opioid receptor. In accordance, it has potent analgesic and diuretic effects in animals, and also has sedative effects and stimulates appetite.
GR 85571 · GR103545 · GR 103545
GR-89696 is a drug which acts as a highly selective κ-opioid agonist. It shows selective effects in different animal models and it is thought it may be a subtype-selective agonist for the κ2 subtype. Recent studies have suggested that GR-89696 and related κ2-selective agonists may be useful for preventing the itching which is a common side effect of conventional opioid analgesic drugs, without the additional side effects of non-selective kappa agonists.

bremazocine hydrochloride, (2R)-isomer · bremazocine hydrochloride, (+-)-isomer · 2-(1-hydroxy-cyclopropylmethyl)-5-ethyl-9,9-dimethyl-2'-hydroxy-6,7-benzomorphan
Bremazocine is a κ-opioid receptor agonist related to pentazocine. It has potent and long-lasting analgesic and diuretic effects. It has 200 times the activity of morphine, but appears to have no addictive properties and does not depress breathing.
Allylnormorphine · Nalorphine Hydrochloride · Lethidrone
Nalorphine (INN) (brand names Lethidrone, Nalline), also known as N-allylnormorphine, is a mixed opioid agonist–antagonist with opioid antagonist and analgesic properties. It was introduced in 1954 and was used as an antidote to reverse opioid overdose and in a challenge test to determine opioid dependence. It acts at two opioid receptors — the μ-opioid receptor (MOR) where it has antagonistic effects, and at the κ-opioid receptor (KOR) (Ki = 1.6 nM; EC50 = 483 nM; Emax = 95%) where it exerts high-efficacy partial agonist/near-full agonist characteristics.

TFMPP · 1-(m-trifluoromethylphenyl)piperazine · 1-(3-trifluoromethylphenyl)piperazine
3-Trifluoromethylphenylpiperazine (TFMPP) is a recreational drug of the piperazine chemical class. Usually in combination with its analogue benzylpiperazine (BZP), it is sold as an alternative to the illicit drug MDMA ("Ecstasy") under the name "Legal X".

TENOCYCLIDINE (21500-98-1, 1867-65-8)
Tenocyclidine (TCP) was discovered by a team at Parke Davis in the late 1950s. It is a dissociative anesthetic drug with psychostimulant and hallucinogenic effects. It is similar in effects to phencyclidine (PCP) but is considerably more potent.
Epibatidine is a putative alkaloid that is secreted by the Ecuadoran frog Epipedobates anthonyi. It was discovered by John W. Daly in 1974, but its structure was not fully elucidated until 1992.

Narcan · Naloxone Hydrochloride · Nalone
Naloxone, sold under the brandname Narcan among others, is a medication used to block the effects of opioids, especially in overdose. Naloxone may be combined within the same pill as an opioid to decrease the risk of misuse. When given intravenously, naloxone works within two minutes, and when injected into a muscle, it works within five minutes; it may also be sprayed into the nose.
