DOAM (drug)
2,5-Dimethoxy-4-amylamphetamine (DOAM), also known as 2,5-dimethoxy-4-pentylamphetamine, is a lesser-known serotonin receptor agonist and serotonergic psychedelic of the amphetamine and DOx families. Effects DOAM was first synthesized by Alexander Shulgin. In his book '' PiHKAL (Phenethylamines i Have Known And Loved)'', the minimum dosage is listed as 10mg orally and the duration is unknown. DOAM was reported to produce a bare threshold and tenseness. In other publications however, DOAM has been said to produce threshold effects at 5 to 10mg orally and to be hallucinogenic at a dose of 40mg, with about 10-fold higher potency than mescaline. In any case, it shows far lower psychedelic potency than other DOx drugs such as DOM. No qualitative description of its effects at hallucinogenic doses is available. Pharmacology DOAM has been found to be a moderate-efficacy partial agonist of the serotonin 5-HT2A receptor. It also shows lower affinity for the serotonin 5-HT2C receptor, ...

Oral Administration
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mescaline
Mescaline, also known as mescalin or mezcalin, and in chemical terms 3,4,5-trimethoxyphenethylamine, is a natural product, naturally occurring psychedelic drug, psychedelic alkaloid, protoalkaloid of the substituted phenethylamine class, found in Cactus, cacti like peyote (''Lophophora williamsii'') and San Pedro cactus, San Pedro (certain species of the Echinopsis genus) and known for its Serotonin, serotonergic Hallucinogen, hallucinogenic effects. Mescaline is typically taken orally and used recreationally, spiritually, and medically, with psychedelic effects occurring at doses from 100 to 1,000 mg, including microdosing below 75 mg, and it can be consumed in pure form or via mescaline-containing cacti. Mescaline induces a psychedelic experience characterized by vivid visual patterns, altered perception of time and self, synesthesia, and spiritual effects, with an onset of 0.5–0.9 hours and a duration that increases with dose, ranging from about 6 to 14 hours. Mescaline h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2,5-Dimethoxy-4-methylamphetamine
2,5-Dimethoxy-4-methylamphetamine (DOM), also known as STP (standing for "Serenity, Tranquility, and Peace" and/or other phrases), is a psychedelic drug of the phenethylamine, amphetamine, and DOx families. It is generally taken orally. DOM was first synthesized by Alexander Shulgin, and later described in his book '' PiHKAL: A Chemical Love Story'' (1991). It is classified as a Schedule I controlled substance in the United States, and is similarly controlled in other parts of the world. Internationally, it is a Schedule I drug under the Convention on Psychotropic Substances. Effects Effects of this drug include substantial perceptual changes such as blurred vision, multiple images, vibration of objects, visual alterations, distorted shapes, enhancement of details, slowed passage of time, increased sexual drive and pleasure, and increased contrasts. It may cause mystical experiences and changes in consciousness. It may also cause pupillary dilation and a rise in systo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Discrimination
Drug discrimination (DD) is a technique in behavioral neuroscience used to evaluate the discriminative stimulus properties or interoceptive cues of psychoactive drugs. In drug discrimination, a subject is trained on a training drug, and then it is tested with novel drugs to see if the novel drugs are experienced as similar to the training drug. In essence, the drug discrimination paradigm has the subject "tell" the experimenter "I think you gave me the training drug" or "I don't think you gave me anything". The discriminative stimulus properties of drugs are believed to reflect their subjective effects. When partial or full stimulus generalization of a test drug to a training drug occurs, the test drug can be assumed to have effects that are subjectively similar to those of the training drug. Drug discrimination tests are usually performed in animals, but have also been conducted in humans. Drug discrimination assays have been employed to assess whether drugs have stimulant- ...

Monoamine Transporter
Monoamine transporters (MATs) are proteins that function as integral Cell membrane, plasma-membrane Neurotransmitter transporter, transporters to regulate concentrations of extracellular monoamine neurotransmitters. The three major classes are serotonin transporters (SERTs), dopamine transporters (DATs), and norepinephrine transporters (NETs) and are responsible for the reuptake of their associated amine neurotransmitters (serotonin, dopamine, and norepinephrine). MATs are located just outside the synaptic cleft (peri-synaptically), transporting monoamine transmitter overflow from the synaptic cleft back to the cytoplasm of the pre-synaptic neuron. MAT regulation generally occurs through protein phosphorylation and post-translational modification. Due to their significance in neuronal signaling, MATs are commonly associated with drugs used to Psychiatric medication, treat mental disorders as well as recreational drugs. Compounds targeting MATs range from medications such as the wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trace Amine-associated Receptor 1
Trace amine-associated receptor 1 (TAAR1) is a trace amine-associated receptor (TAAR) protein that in humans is encoded by the ''TAAR1'' gene. TAAR1 is a primarily intracellular amine-activated and G protein-coupled receptor (GPCR) that is primarily expressed in several peripheral organs and cells (e.g., the stomach, small intestine, duodenum, and white blood cells), astrocytes, and in the intracellular milieu within the presynaptic plasma membrane (i.e., axon terminal) of monoamine neurons in the central nervous system (CNS). TAAR1 is one of six functional human TAARs, which are so named for their ability to bind endogenous amines that occur in tissues at trace concentrations. TAAR1 plays a significant role in regulating neurotransmission in dopamine, norepinephrine, and serotonin neurons in the CNS; it also affects immune system and neuroimmune system function through different mechanisms. Endogenous ligands of the TAAR1 include trace amines, monoamine neurotransmitter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5-HT2B Receptor
5-Hydroxytryptamine receptor 2B (5-HT2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the ''HTR2B'' gene. 5-HT2B is a member of the 5-HT2 receptor, 5-HT2 receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, the 5-HT2B receptor is Gq protein, Gq/G11-protein coupled, leading to downstream activation of phospholipase C. Tissue distribution and function First discovered in the stomach of rats, 5-HT2B was challenging to characterize initially because of its structural similarity to the other 5-HT2 receptors, particularly 5-HT2C. The 5-HT2 receptors (of which the 5-HT2B receptor is a subtype) mediate many of the central and peripheral physiologic functions of serotonin. Cardiovascular effects include contraction of blood vessels and shape changes in platelets; central nervous system (CNS) effects include neuronal sensitization to tactile stimuli and mediation of some of the effects of halluci ...

5-HT1A Receptor
The serotonin 1A receptor (or 5-HT1A receptor) is a subtype of serotonin receptors, or 5-HT receptors, that binds serotonin, also known as 5-HT, a neurotransmitter. 5-HT1A is expressed in the brain, spleen, and neonatal kidney. It is a G protein-coupled receptor (GPCR), coupled to the Gi protein, and its activation in the brain mediates hyperpolarization and reduction of firing rate of the postsynaptic neuron. In humans, the serotonin 1A receptor is encoded by the HTR1A gene. Distribution The 5-HT1A receptor is the most widespread of all the 5-HT receptors. In the central nervous system, 5-HT1A receptors exist in the cerebral cortex, hippocampus, Septum pellucidum, septum, amygdala, and Raphe nuclei, raphe nucleus in high densities, while low amounts also exist in the basal ganglia and thalamus. The 5-HT1A receptors in the raphe nucleus are largely somatodendritic autoreceptors, whereas those in other areas such as the hippocampus are postsynaptic receptors. Function Neur ...

5-HT2C Receptor
The 5-HT2C receptor is a subtype of the 5-HT2 receptor that binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, it is a G protein-coupled receptor (GPCR) that is coupled to Gq/G11 and mediates excitatory neurotransmission. ''HTR2C'' denotes the human gene encoding for the receptor, that in humans is located on the X chromosome. As males have one copy of the gene and females have one of the two copies of the gene repressed, polymorphisms at this receptor can affect the two sexes to differing extent. Structure At the cell surface the receptor exists as a homodimer. The crystal structure has been known since 2018. Distribution 5-HT2C receptors are located mainly in the choroid plexus, and in rats is also found in many other brain regions in high concentrations, including parts of the hippocampus, anterior olfactory nucleus, substantia nigra, several brainstem nuclei, amygdala, subthalamic nucleus and lateral habenula. ...

Affinity (pharmacology)
In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from Latin ''ligare'', which means 'to bind'. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformational isomerism (conformation) of the target protein. In DNA-ligand binding studies, the ligand can be a small molecule, ion, or protein which binds to the DNA double helix. The relationship between ligand and binding partner is a function of charge, hydrophobicity, and molecular structure. Binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and Van der Waals forces. The association or docking is actually reversible through dissociation. Measurably irreversible covalent bonding between a ligand and target molecule is atypical in biological systems. In contrast to the definition o ...

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] |
Serotonin
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and vas ...
