Surinabant
Surinabant (SR147778) is a cannabinoid receptor type 1 antagonist developed by Sanofi-Aventis. It is being investigated as a potential treatment for nicotine addiction, to assist smoking cessation. It may also be developed as an anorectic drug to assist with weight loss, however there are already several CB1 antagonists or inverse agonists on the market or under development for this application, so surinabant is at present mainly being developed as an anti-smoking drug, with possible application in the treatment of other addictive disorders such as alcoholism. Other potential applications such as treatment of ADHD have also been proposed. A dose ranging study was done for smoking cessation in 2012; it did not improve success rate, but reduced weight gain. Inhibition of THC effects on heart rate was seen at 20 mg and 60 mg but not 5 mg.

Cannabinoid Receptor Antagonist
A cannabinoid receptor antagonist, also known simply as a cannabinoid antagonist or as an anticannabinoid, is a type of cannabinoidergic drug that binds to cannabinoid receptors (CBR) and prevents their activation by endocannabinoids. They include antagonists, inverse agonists, and antibodies of CBRs. The discovery of the endocannabinoid system led to the development of CB1 receptor antagonists. The first CBR inverse agonist, rimonabant, was described in 1994. Rimonabant blocks the CB1 receptor selectively and has been shown to decrease food intake and regulate body-weight gain. The prevalence of obesity worldwide is increasing dramatically and has a great impact on public health. The lack of efficient and well-tolerated drugs to cure obesity has led to an increased interest in research and development of CBR antagonists. Cannabidiol (CBD), a naturally occurring cannabinoid and a non-competitive CB1/CB2 receptor antagonist, as well as Δ9-tetrahydrocannabivarin (THCV), a naturally ...

O-1269
O-1269 is a drug that is a diarylpyrazole derivative, related to potent cannabinoid antagonist drugs such as rimonabant and surinabant. However O-1269 and several related drugs were unexpectedly found to act as full or partial agonists at the cannabinoid receptors rather than antagonists, and so produce the usual effects expected of cannabinoid agonists in animal tests, such as sedation and analgesic An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in s ... effects. The ''N''- heptyl homolog O-1270 and the ''N''- propyl homolog O-1399 also act as cannabinoid agonists with similar potency ''in vivo'', despite weaker binding affinity at cannabinoid receptors compared to the pentyl homolog O-1269. Agonist-like and atypical cannabinoid activity has also been observed with a number of rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucinogen Antidotes
A trip killer, also known as a hallucinogen antidote or hallucinogen antagonist, is a drug that aborts or reduces the effects of a hallucinogenic drug experience (or 'trip'). As there are different types of hallucinogens that work in different ways, there are different types of trip killers. They can completely block or reduce the effects of hallucinogens, or they can simply provide anxiety relief and sedation. Examples of trip killers, in the case of serotonergic psychedelics, include serotonin receptor antagonists, such as antipsychotics like risperidone and quetiapine and certain antidepressants like trazodone and mirtazapine, and benzodiazepines, for instance diazepam and alprazolam. Trip killers can be used clinically to manage effects of hallucinogens, like hallucinogenic effects, anxiety, and psychomotor agitation, for instance in the emergency department and in the setting of psychedelic therapy. They are also sometimes used by recreational psychedelic users as a form o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloroarenes
In organic chemistry, an aryl halide (also known as a haloarene) is an aromatic compound in which one or more hydrogen atoms directly bonded to an aromatic ring are replaced by a halide ion (such as fluorine F''−'', chlorine Cl−1,−3,−5, bromine Br−1, or iodine I−). Aryl halides are distinct from haloalkanes (alkyl halides) due to significant differences in their methods of preparation, chemical reactivity, and physical properties. The most common and important members of this class are aryl chlorides, but the group encompasses a wide range of derivatives with diverse applications in organic synthesis, pharmaceuticals, and materials science. Classification according to halide Aryl fluorides Aryl fluorides are used as synthetic intermediates, e.g. for the preparation of pharmaceuticals, pesticides, and liquid crystals. The conversion of diazonium salts is a well established route to aryl fluorides. Thus, anilines are precursors to aryl fluorides. In the classic Schiemann ...

Cannabinoids
Cannabinoids () are several structural classes of compounds found primarily in the ''Cannabis'' plant or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 100 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include aminoalkylindoles, 1,5-diarylpyrazoles, quinolines, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid Receptor Type 1
Cannabinoid receptor 1 (CB1), is a G protein-coupled cannabinoid receptor that in humans is encoded by the ''CNR1'' gene. And discovered, by determination and characterization in 1988, and cloned in 1990 for the first time. The human CB1 receptor is expressed in the peripheral nervous system and central nervous system. It is activated by endogenous cannabinoids called endocannabinoids, a group of retrograde neurotransmitters that include lipids, such as anandamide and 2-arachidonoylglycerol; plant phytocannabinoids, such as docosatetraenoylethanolamide found in wild dagga, the compound tetrahydrocannabinol which is an active constituent of the psychoactive drug cannabis; and synthetic analogs of tetrahydrocannabinol. CB1 is antagonized by the phytocannabinoid tetrahydrocannabivarin at low doses and at higher doses, it activates the CB1 receptor as an agonist, but with less potency than tetrahydrocannabinol. The primary endogenous agonist of the human CB1 receptor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antagonist (pharmacology)
A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. Antagonist drugs interfere in the natural operation of receptor proteins.Pharmacology Guide: In vitro pharmacology: concentration-response curves ." '' GlaxoWellcome.'' Retrieved on December 6, 2007. They are sometimes called blockers; examples include s, |
ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of sustained attention to tasks, inhibitory deficits also can lead to diffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
