Opioid
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 withdrawal. Opioids can cause death and have been used for executions in the United States. Side effects of opioids may include itchiness, sedation, nausea, respiratory depression, constipation, and euphoria. Long-term use can cause 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. The euphoria attracts recreational use, and frequent, escalating recreational use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fentanyl
Fentanyl, also spelled fentanil, is a very potent synthetic opioid used as a pain medication. Together with other drugs, fentanyl is used for anesthesia. It is also used illicitly as a recreational drug, sometimes mixed with heroin, cocaine, benzodiazepines or methamphetamine, among others. Its potentially deadly overdose effects can be neutralized by naloxone. Fentanyl is commonly used to create counterfeit pills disguised as OxyContin, Xanax, Adderall, among others. It has a rapid onset and its effects generally last under two hours. Medically, it is used by injection, nasal spray, or skin patch, or absorbed through the cheek as a lozenge or tablet. Common adverse effects of fentanyl include nausea, vomiting, constipation, itching, sedation, confusion, and injuries related to poor coordination. Serious adverse effects may include respiratory depression, hallucinations, serotonin syndrome, low blood pressure, or development of an opioid use disorder. Fentanyl works b ...

Cyclopropyl Compounds
A cyclopropyl group is a chemical structure derived from cyclopropane, and can participate in organic reactions that constitute cycloadditions and rearrangement organic reactions of cyclopropane. The group has an empirical formula of C3H5 and chemical bond A chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules and crystals. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds, or through the sharing of ...s from each of the three carbons to both of the other two. Structure and bonding Due to the unfavoured bond angles (60°), cyclopropyl groups are highly strained. Two orbital models were proposed to describe the bonding situation. The Coulson-Moffit model uses bent bonds. The C-C bonds are formed by overlap of two sp-hybrid orbitals. To adapt to the small bond angle, there is some rehybridization resulting in sp~5-hybrids for the ring bonds and sp~2 for the C-H bonds. This model ...

Heterocyclic Compounds With 6 Rings
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of known compounds are heterocycles. 59% of US FDA-approved drugs contain nitrogen heterocycles. Classification The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of pyridine, thiophene, pyrrole, and furan are quinol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Etorphine
Etorphine (M99) is a semi-synthetic opioid possessing an analgesic potency approximately 1,000–3,000 times that of morphine. It was first prepared in 1960 from oripavine, which does not generally occur in opium poppy extract but rather the related plants ''Papaver orientale'' and ''Papaver bracteatum''. It was later reproduced in 1963 by a research group at MacFarlan Smith in Gorgie, Edinburgh, led by Kenneth Bentley. It can also be produced from thebaine. Veterinary use Etorphine is available legally only for veterinary use and is strictly governed by law. It is often used to immobilize elephants and other large mammals. Diprenorphine (Revivon) is an opioid receptor antagonist that can be administered in proportion to the amount of etorphine used (1.3 times) to reverse its effects. Veterinary-strength etorphine is fatal to humans. For this reason the package as supplied to vets always includes the human antidote along with the etorphine. The human antidote is generally na ...

Narcotic
The term narcotic (, from ancient Greek ναρκῶ ''narkō'', "to make numb") originally referred medically to any psychoactive compound with numbing or paralyzing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. 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. When used in a legal context in the U.S., a narcotic drug is totally prohibited, such as heroin, or one that is used in violation of legal regulation (in this word sense, equal to any controlled substance or illicit drug). In the medical community, the term is more precisely defined and genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etonitazene
Etonitazene is an analgesic drug, first reported in 1957, that has been shown to have approximately 1,000 to 1,500 times the potency of morphine in animals. Because it is characterized by a strong dependency potential and a tendency to produce profound respiratory depression, it is not used in humans. It is, however, useful in animal models for addiction studies, particularly those requiring the animals to drink or ingest the agent, because it is not as bitter as opiate salts like morphine sulfate. Synthesis Etonitazene and its related opioid agonist benzimidazoles were discovered in the late 1950s, by a team of Swiss researchers working at the pharmaceutical firm CIBA (now Novartis). One of the first compounds investigated by the Swiss team was 1-(β-diethylaminoethyl)-2-benzylbenzimidazole, which was found to possess 10% of the analgesic activity of morphine when tested in rodent bioassays. This finding encouraged the group to begin a comprehensive systematic study of 2-benzyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
