5-MAPB
5-MAPB, also known as 5-(''N''-methyl-2-aminopropyl)benzofuran, is an entactogen and designer drug of the amphetamine family that is similar to MDMA in its structure and effects. It has been patented by Tactogen as an entactogen for potential use as a medicine. Pharmacology Pharmacodynamics 5-MAPB acts as a serotonin–norepinephrine–dopamine releasing agent with values for induction of monoamine release of 64nM for serotonin, 24nM for norepinephrine, and 41nM for dopamine using rat brain synaptosomes. It is also a partial agonist of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors. 5-MAPB has been described by Matthew Baggott as the MDMA analogue so far known that has the closest effects and so-called "magic" to MDMA itself. Other analogues that lack the full quality of MDMA include MBDB, methylone, 6-APDB, 5-APDB, 6-APB, 5-APB, MDAT, and MDAI, among others. 5-MAPB has been marketed as a less- or non-neurotoxic alternative to MDMA. However, 5-MAPB has been f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monoamine Releasing Agent
A monoamine releasing agent (MRA), or simply monoamine releaser, is a drug that induces the release of one or more monoamine neurotransmitters from the presynaptic neuron into the synapse, leading to an increase in the extracellular concentrations of the neurotransmitters and hence enhanced signaling by those neurotransmitters. The monoamine neurotransmitters include serotonin, norepinephrine, and dopamine; MRAs can induce the release of one or more of these neurotransmitters. MRAs work by reversing the direction of the monoamine transporters (MATs), including the serotonin transporter (SERT), norepinephrine transporter (NET), and/or dopamine transporter (DAT), causing them to promote efflux of non-vesicular cytoplasmic monoamine neurotransmitter rather than reuptake of synaptic monoamine neurotransmitter. Many, but not all MRAs, also reverse the direction of the vesicular monoamine transporter 2 (VMAT2), thereby additionally resulting in efflux of vesicular monoamine neuro ...

Serotonergic Neurotoxin
A monoamine neurotoxin, or monoaminergic neurotoxin, is a drug that selectively damages or destroys monoaminergic neurons. Monoaminergic neurons are neurons that signal via stimulation by monoamine neurotransmitters including serotonin, dopamine, and norepinephrine. Examples of monoamine neurotoxins include the serotonergic neurotoxins ''para''-chloroamphetamine (PCA), methylenedioxymethamphetamine (MDMA), and 5,7-dihydroxytryptamine (5,7-DHT); the dopaminergic neurotoxins oxidopamine (6-hydroxydopamine), MPTP, and methamphetamine; and the noradrenergic neurotoxins oxidopamine and DSP-4. In the case of serotonergic neurotoxins like MDMA, research suggests that simultaneous induction of serotonin and dopamine release, serotonin depletion, dopamine uptake and metabolism, hyperthermia, oxidative stress and antioxidant depletion, and/or drug metabolites may all be involved in the neurotoxicity. On the other hand, there is evidence that drug metabolites may not be involved. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entactogen
Entactogens, also known as empathogens or connectogens, are a class of psychoactive drugs that induce the production of experiences of emotional communion, oneness, connectedness, emotional openness—that is, empathy—as particularly observed and reported for experiences with MDMA. This class of drug is distinguished from the classes of hallucinogens or psychedelics and stimulants, although entactogens, for instance MDMA, can also have these properties. Entactogens are used both as recreational drugs and are being investigated for medical use in the treatment of psychiatric disorders, for instance MDMA-assisted therapy for post-traumatic stress disorder (PTSD). Notable members of this class include MDMA, MDA, MDEA, MDOH, MBDB, 5-APB, 5-MAPB, 6-APB, 6-MAPB, methylone, mephedrone, αMT, αET, and MDAI, among others. Most entactogens are phenethylamines and amphetamines, although several, such as αMT and αET, are tryptamines. When referring to MDMA and its cou ...

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 ...

Chemical Structure
A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together and can be represented using structural formulae and by molecular models; complete electronic structure descriptions include specifying the occupation of a molecule's molecular orbitals. Structure determination can be applied to a range of targets from very simple molecules (e.g., diatomic oxygen or nitrogen) to very complex ones (e.g., such as protein or DNA). Background Theories of chemical structure were first developed by August Kekulé, Archibald Scott Couper, and Aleksandr Butlerov, among others, from about 1858. These theories were first to state that chemical compounds are not a ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell (biology)
The cell is the basic structural and functional unit of all life, forms of life. Every cell consists of cytoplasm enclosed within a Cell membrane, membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word meaning 'small room'. Most cells are only visible under a light microscope, microscope. Cells Abiogenesis, emerged on Earth about 4 billion years ago. All cells are capable of Self-replication, replication, protein synthesis, and cell motility, motility. Cells are broadly categorized into two types: eukaryotic cells, which possess a Cell nucleus, nucleus, and prokaryotic, prokaryotic cells, which lack a nucleus but have a nucleoid region. Prokaryotes are single-celled organisms such as bacteria, whereas eukaryotes can be either single-celled, such as amoebae, or multicellular organism, multicellular, such as some algae, plants, animals, and fungi.

Neurotoxicity
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant– alters the normal activity of the nervous system in such a way as to cause permanent or reversible damage to nervous tissue. This can eventually disrupt or even kill neurons, which are cells that transmit and process signals in the brain and other parts of the nervous system. Neurotoxicity can result from organ transplants, radiation treatment, certain drug therapies, recreational drug use, exposure to heavy metals, bites from certain species of venomous snakes, pesticides, certain industrial cleaning solvents, fuels and certain naturally occurring substances. Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/or inte ...

MDAI
MDAI, also known as 5,6-methylenedioxy-2-aminoindane, is an entactogen drug of the 2-aminoindane group which is related to MDMA and produces similar subjective effects. It acts as a selective serotonin and norepinephrine releasing agent (SNRA). The drug shows greatly reduced serotonergic neurotoxicity in comparison to MDMA in animals, although it still shows weak capacity for neurotoxicity with chronic use or in combination with amphetamine. MDAI was developed in the 1990s by a team led by David E. Nichols at Purdue University. It has been encountered as a designer drug and has been used recreationally with reported street names such as "sparkle" and "mindy". In addition to its recreational use, there has been interest in MDAI for potential use in medicine, for instance in drug-assisted psychotherapy. Uses Scientific research MDAI and other similar drugs have been widely used in scientific research, as they are able to replicate many of the effects of MDMA, but without c ...

MDAT
6,7-Methylenedioxy-2-aminotetralin (MDAT) is a drug developed in the 1990s by a team at Purdue University led by David E. Nichols. It appears to act as a serotonin releasing agent based on rodent drug discrimination assays comparing it to MDMA, in which it fully substitutes for, and additionally lacks any kind of serotonergic neurotoxicity. Hence, MDAT is considered likely to be a non-neurotoxic, putative entactogen in humans. See also * 2-Aminotetralin 2-Aminotetralin (2-AT), also known as 1,2,3,4-tetrahydronaphthalen-2-amine (THN), is a stimulant drug with a chemical structure consisting of a tetralin core with an amine as substituent. 2-AT is a rigid analogue of phenylisobutylamine and ful ...

5-APB
5-APB (abbreviation of "5-(2-aminopropyl)benzofuran") is an empathogenic psychoactive compound of the phenethylamine, amphetamine, and benzofuran families. The drug and other compounds have sometimes been informally called "Benzofury". 5-APB has been sold as a designer drug since 2010. Effects Users describe the effects of 5-APB as including euphoria among others. Largely, its effects reported were similar to those of the drug MDMA but not as strong. The drug has been reported to produce visual disturbances and is said to have mild psychedelic effects. Recreational use of 5-APB has been associated with death in combination with other drugs and solely as the result of 5-APB. Pharmacology 5-APB acts as a serotonin–norepinephrine–dopamine releasing agent (SNDRA), with values for monoamine release of 19nM for serotonin, 21nM for norepinephrine, and 31nM for dopamine in rat brain synaptosomes. It is also a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
