Bucinnazine
Bucinnazine (AP-237, 1-butyryl-4-cinnamylpiperazine) is an opioid analgesic drug that was widely used in China to treat pain in cancer patients as of 1986. It is one of the most potent compounds among a series of piperazine-amides first synthesized and reported in Japan in the 1970s. Bucinnazine has analgesic potency comparable to that of morphine but with a relatively higher therapeutic index. The drug was initially claimed to be a non-narcotic analgesic. However, subsequent studies have shown bucinnazine and similar acyl piperazines to be potent and selective agonists of μ-opioid receptor (MOR) with relatively low affinity for the δ-opioid receptor and the κ-opioid receptor. In accordance with these studies, results from the intravenous self-administration experiments in rats showed that bucinnazine has a marked reinforcing effect with tolerance and dependence quickly developing. In addition, the morphine antagonist naloxone reverses the effect of bucinnazine and preci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MT-45
MT-45 (IC-6) is an opioid analgesic drug invented in the 1970s by Dainippon Pharmaceutical Co. It is chemically a 1-substituted-4-(1,2-diphenylethyl) piperazine derivative, which is structurally unrelated to most other opioid drugs. Racemic MT-45 has around 80% the potency of morphine, with almost all opioid activity residing in the (S) enantiomer (the opposite stereochemistry from the related drug lefetamine). It has been used as a lead compound from which a large family of potent opioid drugs have been developed, including full agonists, partial agonists, and antagonists at the three main opioid receptor subtypes. Fluorinated derivatives of MT-45 such as 2F-MT-45 are significantly more potent as μ-opioid receptor agonists, and one of its main metabolites 1,2-diphenylethylpiperazine also blocks NMDA receptors. ] Side effects Recreational use of MT-45 has been associated with unconsciousness and overdose, as well as a range of unusual side effects not typically seen with othe ...

Synthetic Opioids
Opioids are substances that act on opioid receptors to produce morphine-like effects. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid use disorder, reversing opioid overdose, and suppressing cough. Extremely potent opioids such as carfentanil are approved only for veterinary use. Opioids are also frequently used non-medically for their euphoric effects or to prevent Drug withdrawal, withdrawal. Opioids can cause death and have been used for Capital punishment in the United States, executions in the United States. Side effects of opioids may include itchiness, sedation, nausea, respiratory depression, constipation, and euphoria. Long-term use can cause Drug tolerance, tolerance, meaning that increased doses are required to achieve the same effect, and physical dependence, meaning that abruptly discontinuing the drug leads to unpleasant withdrawal symptoms.

SHR9352
SHR9352 is a drug which acts as a potent and selective biased agonist at the μ-opioid receptor, selective for activation of the G-protein signalling pathway over β-arrestin 2 Beta-arrestin-2, also known as arrestin beta-2, is an intracellular protein that in humans is encoded by the ''ARRB2'' gene. Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization of G prot ... recruitment. It was structurally derived from oliceridine by replacing the benzylic side chain with a cyclised group, although only some compounds in the series retained the desired biased agonist profile, with some derivatives such as compound 12 being potent, unbiased μ-opioid full agonists. ] See also * PZM21 * SR-17018 * TRV734 References External links * Mu-opioid receptor agonists Dithiolanes 2-Pyridyl compounds Spiro compounds {{pharm-stub ...

Piperidylthiambutene
Piperidylthiambutene (Piperidinohton) is a synthetic opioid analgesic drug from the thiambutene family, which has around the same potency as morphine. Piperidylthiambutene is structurally distinct from fentanyl, its analogues, and other synthetic opioids previously reported. If sold or obtained for the purpose of human consumption it could be considered a controlled substance analogue in some countries such as the US, Australia and New Zealand. Piperidylthiambutene has been sold as a designer drug A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests.

O-DSMT
Desmetramadol (), also known as ''O''-desmethyltramadol (''O''-DSMT), is an opioid analgesic and the main active metabolite of tramadol. Tramadol is demethylated by the liver enzyme CYP2D6 in the same way as codeine, and so similarly to the variation in effects seen with codeine, individuals who have a less active form of CYP2D6 ("poor metabolizers") will tend to get reduced analgesic effects from tramadol. This also results in a ceiling effect (dependent on CYP2D6 availability) which limits tramadol's range of therapeutic benefits to the treatment of moderate pain. Pharmacology Pharmacodynamics (+)-Desmetramadol is a G-protein biased μ-opioid receptor full agonist. It shows comparatively far lower affinity for the δ- and κ-opioid receptors. The two enantiomers of desmetramadol show quite distinct pharmacological profiles; both (+) and (−)-desmetramadol are inactive as serotonin reuptake inhibitors, but (−)-desmetramadol retains activity as a norepinephrine reuptake inhi ...

Nortilidine is the major active metabolite of tilidine. It is formed from tilidine by demethylation in the liver. The racemate has opioid analgesic effects roughly equivalent in potency to that of morphine. The (1R,2S) isomer has NMDA antagonist activity. The drug also acts as a dopamine reuptake inhibitor.

Etodesnitazene
Etodesnitazene (Desnitroetonitazene, Etazen, Etazene, Etazone) is a benzimidazole derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives. It is many times less potent than etonitazene itself, but still 70x more potent than morphine in animal studies. Corresponding analogues where the N,N-diethyl group is replaced by piperidine or pyrrolidine rings also retain significant activity (10x and 20x morphine respectively). Etodesnitazene has been sold as a designer drug, first being identified in both Poland and Finland in March 2020.
