LPH-48
LPH-48 is a selective serotonin 5-HT2A receptor agonist and psychedelic hallucinogen which is under development for the treatment of alcoholism. Its route of administration has not been specified. The drug acts as a selective agonist of the serotonin 5-HT2A receptor. It is said to be an analogue of LPH-5 with similar characteristics but with faster metabolism and a shorter duration of action. LPH-5 is a highly selective serotonin 5-HT2A receptor agonist that is under development for major depressive disorder and has shown antidepressant-like effects in animals. LPH-48 is under development by Lophora. As of May 2024, it is in preclinical research for alcoholism. The chemical structure of LPH-48 does not yet seem to have been disclosed. However, Lophora has patented selective serotonin 5-HT2A receptor agonists for treatment of depression and the company is said to have patent protection for LPH-48. Additionally, the structure of its close analogue LPH-5 is known and this com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LPH-5 (drug)
LPH-5 is a psychedelic discovered by Emil Marcher-Rørsted, Jesper L. Kristensen and Anders A. Jensen at Danish biopharmaceutical company Lophora. It is a conformationally-restricted derivative of the phenethylamine 2C-TFM, also a hallucinogen, and acts as a potent agonist of the 5-HT2A receptor (EC50 = 3.2 nM, Emax = 78%). It shows 10- to 100-fold selectivity for the 5-HT2A receptor over the 5-HT2B and 5-HT2C receptors and, along with related compounds like 25CN-NBOH, is said to be one of the few truly selective 5-HT2A receptor agonists. LPH-5 is expected to avoid the cardiac risks of 5-HT2B receptor activation. LPH-48, an analogue of LPH-5 that likewise acts as a selective serotonin 5-HT2A receptor agonist and psychedelic hallucinogen and shows similar characteristics but has a shorter duration of action, is also under development by Lophora.

5-HT2A Receptor
The 5-HT2A receptor is a subtype of the 5-HT2 receptor, 5-HT2 receptor that belongs to the serotonin receptor family and functions as a GPCR, G protein-coupled receptor (GPCR). It is a cell surface receptor that activates multiple intracellular signalling cascades. Like all 5-HT2 receptors, the 5-HT2A receptor is coupled to the Gq protein, Gq/G11 signaling pathway. It is the primary excitatory receptor subtype among the serotonin-responsive GPCRs. The 5-HT2A receptor was initially noted for its central role as the primary target of serotonergic psychedelic drugs such as LSD and psilocybin mushrooms. It later regained research prominence when found to mediate, at least in part, the effects of many antipsychotic drugs, particularly atypical antipsychotic, atypical antipsychotics. Downregulation of post-synaptic 5-HT2A receptors is an adaptive response triggered by chronic administration of selective serotonin reuptake inhibitors (SSRIs) and atypical antipsychotics. Elevated 5-HT2A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Hallucinogens
This is a list of investigational hallucinogens and entactogens, or hallucinogens and entactogens that are currently under formal development for clinical use but are not yet approved. ''Chemical/generic names are listed first, with developmental code names, synonyms, and brand names in parentheses.'' The list also includes non-hallucinogenic drugs related to hallucinogens, such as non-hallucinogenic serotonin 5-HT2A receptor agonists and non-hallucinogenic ketamine analogues. Cannabinoids, or cannabinoid receptor modulators, are not included in this list. Many of the indications are not for continuous medication therapy but rather are for medication-assisted psychotherapy or short-term use only. The section that the drug is in corresponds to its highest developmental phase, not its phase for all listed indications. This list was last comprehensively updated in October 2024. It is likely to become outdated with time. Under development Preregistration * Midomafetamine (MDMA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMB-202
BMB-202 is a serotonin 5-HT2A receptor agonist and psychedelic hallucinogen which is under development for the treatment of depressive disorders and post-traumatic stress disorder (PTSD). It is taken by mouth. However, BMB-202 has also been evaluated by injection in preclinical studies. The drug acts as a highly selective full agonist of the serotonin 5-HT2A receptor. In terms of values, it shows 36-fold selectivity for activation of the serotonin 5-HT2A receptor over the serotonin 5-HT2C receptor and 500-fold selectivity for activation of the serotonin 5-HT2A receptor over the serotonin 5-HT2B receptor. It has been claimed by its developer to be the most selective serotonin 5-HT2A receptor agonist yet to be discovered or that is currently under development, at least as of September 2024. BMB-202 induces the head-twitch response (HTR), a behavioral proxy of psychedelic effects, in animals. Hence, it is putatively hallucinogenic in humans. As with other psychedelics like psi ...

Binding Selectivity
In chemistry, binding selectivity is defined with respect to the binding of ligands to a substrate forming a complex. Binding selectivity describes how a ligand may bind more preferentially to one receptor than another. A selectivity coefficient is the equilibrium constant for the reaction of displacement by one ligand of another ligand in a complex with the substrate. Binding selectivity is of major importance in biochemistry and in chemical separation processes. Selectivity coefficient The concept of selectivity is used to quantify the extent to which one chemical substance, A, binds each of two other chemical substances, B and C. The simplest case is where the complexes formed have 1:1 stoichiometry. Then, the two interactions may be characterized by equilibrium constants and .The constant used here are ''association'' constants. ''Dissociation'' constants are used in some contexts. A dissociation constant is the reciprocal of an association constant. \begin \ce;& \quad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antidepressant
Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction. Common side effects of antidepressants include Xerostomia, dry mouth, weight gain, dizziness, headaches, akathisia, sexual dysfunction, and emotional blunting. There is an increased risk of Suicidal ideation, suicidal thinking and Suicide, behavior when taken by children, adolescents, and young adults. Antidepressant discontinuation syndrome, Discontinuation syndrome, which resembles recurrent Depression (mood), depression in the case of the Selective serotonin reuptake inhibitor, SSRI class, may occur after stopping the intake of any antidepressant. Research regarding the effectiveness of antidepressants for depression in adults is controversial and has found both benefits and drawbacks. Meanwhile, evidence of benefit in children and adolescents is unclear, even though antidepressant use has considerably increased in children and adolescents in th ...

Experimental Drugs
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drugs With Undisclosed Chemical Structures
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders. Classification Pharmaceutical drugs are often classified into drug classes—groups of related drugs that have simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Derivative
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction. In the past, derivative also meant a compound that ''can be imagined to'' arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity. The term "structural analogue" is common in organic chemistry. In biochemistry, the word is used for compounds that at least theoretically can be formed from the precursor compound. Chemical derivatives may be used to facilitate analysis. For example, melting point (MP) analysis can assist in identification of many organic compounds. A crystalline derivative may be prepared, such as a semicarbazone or 2,4-dinitrophenylhydrazone (derived from aldehydes or ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is availa ...

Phenylpiperidine
Phenylpiperidines are chemical compounds with a phenyl moiety (chemistry), moiety directly attached to piperidine. Of particular interest are a variety of chemical derivative, derivatives of 4-phenylpiperidine, which have pharmacology, pharmacological effects including morphine-like activity or other central nervous system effects. Some of the butyrophenone antipsychotics, including aceperone, bromperidol, haloperidol, moperone, and trifluperidol, as well as the related diphenylbutylpiperidine antipsychotic penfluridol, are also 4-phenylpiperidine derivatives. Certain other opioids, including alvimopan, loperamide, and diphenoxylate, are 4-phenylpiperidine derivatives as well.

Patent Protection
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mu ...
