Nalorphine Dinicotinate
Nalorphine dinicotinate (trade name Nimelan), also known as ''N''-allylnormorphine dinicotinate, dinicotinoylnalorphine, or niconalorphine, is a semisynthetic, mixed opioid agonist- antagonist which is described as a narcotic antagonist but may produce limited analgesia and sedation at higher doses in opioid naive patients (with limited euphoria and dependence liability). It is the 3,6- dinicotinate ester of nalorphine, and is therefore the nalorphine analogue of nicomorphine (which is the 3,6-dinicotinate ester of morphine). As nalorphine dinicotinate is only regulated at the Rx (prescription required) drug, it would be legal to possess with a valid prescription should a patient manage to acquire it. See also * Diacetylnalorphine Diacetylnalorphine (BAN), also known as ''O''3,''O''6-diacetyl-''N''-allyl-normorphine, is an opioid drug described as an analgesic and antidote which was never marketed. It is the 3,6-diacetyl ester of nalorphine, and therefore the heroin analog . ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Semisynthetic
Semisynthesis, or partial chemical synthesis, is a type of chemical synthesis that uses chemical compounds isolated from natural sources (such as microbial cell cultures or plant material) as the starting materials to produce novel compounds with distinct chemical and medicinal properties. The novel compounds generally have a high molecular weight or a complex molecular structure, more so than those produced by total synthesis from simple starting materials. Semisynthesis is a means of preparing many medicines more cheaply than by total synthesis since fewer chemical steps are necessary. Overview Drugs derived from natural sources are usually produced by isolation from the natural source or, as described here, by semisynthesis from such an isolated agent. From the viewpoint of chemical synthesis, living organisms are remarkable chemical factories that can easily produce structurally-complex chemical compounds by biosynthesis. In contrast, engineered chemical synthesis is necessar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Morphine
Morphine is a strong opiate that is found naturally in opium, a dark brown resin in poppies (''Papaver somniferum''). It is mainly used as a analgesic, pain medication, and is also commonly used recreational drug, recreationally, or to make other illicit drug, illicit opioids. There are numerous methods used to administer morphine: oral; sublingual administration, sublingual; via inhalation; intramuscular, injection into a muscle; by Subcutaneous injection, injection under the skin; intravenously; Intrathecally, injection into the space around the spinal cord; transdermal; or via rectal administration, rectal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during Ch ...

Nicotinate Esters
Niacin, also known as nicotinic acid, is an organic compound and a form of vitamin B3, an essential human nutrient. It can be manufactured by plants and animals from the amino acid tryptophan. Niacin is obtained in the diet from a variety of whole and processed foods, with highest contents in fortified packaged foods, meat, poultry, red fish such as tuna and salmon, lesser amounts in nuts, legumes and seeds. Niacin as a dietary supplement is used to treat pellagra, a disease caused by niacin deficiency. Signs and symptoms of pellagra include skin and mouth lesions, anemia, headaches, and tiredness. Many countries mandate its addition to wheat flour or other food grains, thereby reducing the risk of pellagra. The amide derivative nicotinamide (niacinamide) is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP+). Although niacin and nicotinamide are identical in their vitamin activity, nicotinamide doe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Allyl Compounds
In organic chemistry, an allyl group is a substituent with the structural formula , where R is the rest of the molecule. It consists of a methylene bridge () attached to a vinyl group (). The name is derived from the scientific name for garlic, . In 1844, Theodor Wertheim isolated an allyl derivative from garlic oil and named it "". The term allyl applies to many compounds related to , some of which are of practical or of everyday importance, for example, allyl chloride. Allylation is any chemical reaction that adds an allyl group to a substrate. Nomenclature A site adjacent to the unsaturated carbon atom is called the allylic position or allylic site. A group attached at this site is sometimes described as allylic. Thus, "has an allylic hydroxyl group". Allylic C−H bonds are about 15% weaker than the C−H bonds in ordinary sp3 carbon centers and are thus more reactive. Benzylic and allylic are related in terms of structure, bond strength, and reactivity. Other re ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Diacetylnalorphine
Diacetylnalorphine ( BAN), also known as ''O''3,''O''6-diacetyl-''N''-allyl-normorphine, is an opioid drug described as an analgesic and antidote which was never marketed. It is the 3,6-diacetyl ester of nalorphine, and therefore the heroin analogue of nalorphine. Diacetylnalorphine may behave as a prodrug to nalorphine, similarly to the cases of heroin (diacetylmorphine) to morphine and diacetyldihydromorphine to dihydromorphine. See also * Nalorphine dinicotinate Nalorphine dinicotinate (trade name Nimelan), also known as ''N''-allylnormorphine dinicotinate, dinicotinoylnalorphine, or niconalorphine, is a semisynthetic, mixed opioid agonist- antagonist which is described as a narcotic antagonist but may ...

Nicomorphine
Nicomorphine (Vilan, Subellan, Gevilan, MorZet) is the 3,6-dinicotinate ester of morphine. It is a strong opioid agonist analgesic two to three times as potent as morphine with a side effect profile similar to that of dihydromorphine, morphine, and diamorphine. Nicomorphine was first synthesized in 1904 and was patented as Vilan by Lannacher Heilmittel G.m.b.H. of Austria in 1957. Medical Use The hydrochloride salt is available as ampoules of 10 mg/ml solution for injection, 5 mg tablets, and 10 mg suppositories. It is possible that other manufacturers distribute 10 mg tablets and other concentrations of injectable nicomorphine in ampoules and multidose vials. It is used, particularly in the German-speaking countries and elsewhere in Central Europe and some other countries in Europe and the former USSR in particular, for post-operative, cancer, chronic non-malignant and other neuropathic pain. It is commonly used in patient-controlled analgesia (PCA) units ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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]   |

Structural Analog
A structural analog (analogue in modern traditional English; Commonwealth English), also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or substructures. A structural analog can be imagined to be formed, at least theoretically, from the other compound. Structural analogs are often isoelectronic. Despite a high chemical similarity, structural analogs are not necessarily functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties. In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study or a database is screened for structural analogs of a lead compound. Chemical analogues of il ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
