Serotonin–norepinephrine–dopamine Releasing Agent
A serotonin–norepinephrine–dopamine releasing agent (SNDRA), also known as a triple releasing agent (TRA), is a type of drug which induces the release of serotonin, norepinephrine/epinephrine, and dopamine in the brain and body. SNDRAs produce euphoriant, entactogen, and psychostimulant effects, and are almost exclusively encountered as recreational drugs. A closely related type of drug is a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI). Examples of SNDRAs Examples of SNDRAs include specific amphetamines such as MDMA, MDA, 4-methylamphetamine, methamphetamine (in high doses), certain substituted benzofurans such as 5-APB and 6-APB, naphthylisopropylamine; cathinones such as mephedrone and methylone; tryptamines such as αMT and αET; along with agents of other chemical classes such as 4,4'-DMAR, and 5-IAI.Bruce E.

2-MAPB
2-MAPB is a recreational designer drug with empathogenic effects. As with other related substituted benzofuran derivatives such as 6-APB and 5-MAPB, 2-MAPB is a monoamine releaser with some selectivity for serotonin release, generally similar in pharmacological profile to MDMA but with greater activity as a directly acting agonist of 5-HT2 receptor subtypes and somewhat greater toxicity. 2-MAPB has been isolated from post-mortem toxicology screens in several drug-related fatal adverse reactions but generally only as a component of combinations of drugs, making it difficult to determine how much it contributed to the deaths. It is illegal in Japan.

Monoamine Partial Releaser
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 neurot ...

Potency (pharmacology)
In pharmacology, potency or biological potency is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. A highly potent drug (e.g., fentanyl, clonazepam, risperidone, benperidol, bumetanide) evokes a given response at low concentrations, while a drug of lower potency (e.g. morphine, alprazolam, ziprasidone, haloperidol, furosemide) evokes the same response only at higher concentrations. Higher potency does not necessarily mean greater effectiveness nor more side effects nor less side effects. Types of potency The International Union of Basic and Clinical Pharmacology (IUPHAR) has stated that "potency is an imprecise term that should always be further defined", and lists of types of potency as follows: Miscellaneous Lysergic acid diethylamide (LSD) is one of the most potent psychoactive drug A psychoactive drug, psychopharmaceutical, mind-altering drug, consciousness-altering drug, ...

Synaptosome
A synaptosome is an isolated synaptic terminal from a neuron. Synaptosomes are obtained by mild homogenization of nervous tissue under isotonic conditions and subsequent fractionation using differential and density gradient centrifugation. Liquid shear detaches the nerve terminals from the axon and the plasma membrane surrounding the nerve terminal particle reseals. Synaptosomes are osmotically sensitive, contain numerous small clear synaptic vesicles, sometimes larger dense-core vesicles and frequently one or more small mitochondria. They carry the morphological features and most of the chemical properties of the original nerve terminal. Synaptosomes isolated from mammalian brain often retain a piece of the attached postsynaptic membrane, facing the active zone. Synaptosomes were first isolated in an attempt to identify the subcellular compartment corresponding to the fraction of so-called bound acetylcholine that remains when brain tissue is homogenized in iso-osmotic sucrose. ...

Bioassay
A bioassay is an analytical method to determine the potency or effect of a substance by its effect on animal testing, living animals or plants (''in vivo''), or on living cells or tissues (''in vitro''). A bioassay can be either quantal or quantitative, direct or indirect. If the measured response is binary, the assay is mwod:quantal, quantal; if not, it is Quantitative research, quantitative. A bioassay may be used to detect biological hazards or to give an assessment of the quality of a mixture. A bioassay is often used to monitor water quality as well as wastewater discharges and its impact on the surroundings. It is also used to assess the environmental impact and safety of new technologies and facilities. Bioassays are essential in pharmaceutical, medical and agricultural sciences for development and launching of new drugs, vitamins, etc. Principle A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naphthylmetrazine
Naphthylmetrazine (code name PAL-704), also known as 3-methyl-2-(2′-naphthyl)morpholine, is a monoamine releasing agent (MRA) and monoamine reuptake inhibitor (MRI) of the phenylmorpholine and naphthylaminopropane families related to phenmetrazine. It is a analogue of phenmetrazine in which the phenyl ring has been replaced with a naphthalene ring. The drug acts as a hybrid norepinephrine–dopamine releasing agent (NDRA) and serotonin reuptake inhibitor (SRI). Its values for induction of monoamine release are 111nM for dopamine, 203nM for norepinephrine, and inactive for serotonin in rat brain synaptosomes, whereas its for serotonin reuptake inhibition is 105nM. Hence, it is about equipotent in inducing dopamine release and inhibiting serotonin reuptake and is about 2-fold more potent in these actions than in inducing norepinephrine release. In terms of chemical structure, naphthylmetrazine is to phenmetrazine as naphthylisopropylamine (PAL-287) is to amphetamine. Other ...

Phenmetrazine
Phenmetrazine, sold under the brand name Preludin among others, is a stimulant drug first chemical synthesis, synthesized in 1952 and originally used as an appetite suppressant, but withdrawn drug, withdrawn from the market in the 1980s due to widespread drug misuse, misuse. It was initially replaced by its structural analog, analogue phendimetrazine (under the brand name Prelu-2) which functions as a prodrug to phenmetrazine, but now it is rarely prescribed, due to concerns of misuse and drug addiction, addiction. Chemically, phenmetrazine is a substituted amphetamine containing a morpholine ring (chemistry), ring or a substituted phenylmorpholine. Medical uses Phenmetrazine has been used as an appetite suppressant for purposes of weight loss. It was used therapeutically for this indication at a dosage of 25mg two or three times per day (or 50–75mg/day total) in adults. Phenmetrazine has been found to produce similar weight loss to dextroamphetamine in people with obesity. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylnaphthylaminopropane
Ethylnaphthylaminopropane (ENAP; developmental code name PAL-1045) is a monoamine releasing agent (MRA) of the amphetamine and naphthylaminopropane families that is related to naphthylaminopropane (NAP; PAL-287) and methamnetamine (MNAP; PAL-1046). It acts specifically as a serotonin–norepinephrine–dopamine releasing agent (SNDRA). However, ENAP is unusual in being a partial releaser of serotonin and dopamine and a full releaser of norepinephrine. The () values of ENAP in terms of monoamine release induction are 12nM (66%) for serotonin, 46nM (78%) for dopamine, and 137nM (94%) for norepinephrine in rat brain synaptosomes. In contrast to NAP and MNAP, which produce clearly dose-dependent increases in locomotor stimulation and brain monoamine levels in rodents, ENAP has been found to show attenuated monoamine elevations and a "flat" dose–response curve. Relatedly, it may have less misuse liability than other drugs like amphetamine, although more research is necessar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
