3,4-Methylenedioxyamphetamine is an empathogen-entactogen, psychostimulant, and psychedelic drug of the amphetamine family that is encountered mainly as a recreational drug. In its pharmacology, MDA is a serotonin–norepinephrine–dopamine releasing agent (SNDRA). In most countries, the drug is a controlled substance and its possession and sale are illegal.
Amifampridine is used as a drug, predominantly in the treatment of a number of rare muscle diseases. The free base form of the drug has been used to treat congenital myasthenic syndromes and Lambert–Eaton myasthenic syndrome (LEMS) through compassionate use programs since the 1990s and was recommended as a first line treatment for LEMS in 2006, using ad hoc forms of the drug, since there was no marketed form.
Ganesha (2,5-dimethoxy-3,4-dimethylamphetamine) is a lesser-known psychedelic drug. It is also a substituted amphetamine. It was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 24–32 mg. The drug is usually taken orally, although other routes such as rectally may also be used. Ganesha is synthesized from 2,5-dimethoxy-3,4-dimethylbenzaldehyde. Ganesha is the amphetamine analog of 2C-G. It is a particularly long lasting drug, with the duration listed in PiHKAL as being 18–24 hours, which might make it undesirable to some users. It is named after the Hindu deity, Ganesha. Very little is known about the dangers or toxicity of ganesha. Effects of ganesha include:
Corbadrine, sold under the brand name Neo-Cobefrine and also known as levonordefrin and α-methylnorepinephrine, is a catecholamine sympathomimetic used as a topical nasal decongestant and vasoconstrictor in dentistry in the United States. It is usually used in a pre-mixed solution with local anesthetics, such as mepivacaine.
The substituted methylenedioxyphenethylamines represent a diverse chemical class of compounds derived from phenethylamines. This category encompasses numerous psychoactive substances with entactogenic, psychedelic, and/or stimulant properties, in addition to entheogens. These compounds find application as research chemicals, designer drugs, and recreational substances.
3,4-Dimethoxyphenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine.
Dimethoxyamphetamine (DMA) is a series of six lesser-known psychedelic drugs similar in structure to the three isomers of methoxyamphetamine and six isomers of trimethoxyamphetamine. The isomers are 2,3-DMA, 2,4-DMA, 2,5-DMA, 2,6-DMA, 3,4-DMA, and 3,5-DMA. Three of the isomers were characterized by Alexander Shulgin in his book PiHKAL. Little is known about their dangers or toxicity.
2,5-Dimethoxy-3,4-methylenedioxyamphetamine is a lesser-known psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized by Alexander Shulgin and was described in his book PiHKAL. Shulgin listed the dosage as 30–75 mg and the duration as 6–8 hours. He reported DMMDA as producing LSD-like images, mydriasis, ataxia, and time dilation. DMMDA isn't mentioned much in literature outside PiHKAL unlike 2C-B.
1,3-Benzodioxolylbutanamine is an entactogenic drug of the phenethylamine chemical class. It is the α-ethyl analog of MDPEA and MDA and the methylenedioxy analogue of α-ethylphenethylamine.
Etaqualone is a quinazolinone-class GABAergic and is an analogue of methaqualone that was developed in the 1960s and marketed mainly in France and some other European countries. It has sedative, hypnotic, muscle relaxant and central nervous system depressant properties resulting from its agonist activity at the β-subtype of the GABAA receptor, and was used for the treatment of insomnia.
3,4-Methylenedioxyphenethylamine, also known as 3,4-MDPEA, MDPEA, and homopiperonylamine, is a substituted phenethylamine formed by adding a methylenedioxy group to phenethylamine. It is structurally similar to MDA, but without the methyl group at the alpha position.
The 2003 WGC-NEC Invitational was a golf tournament that was contested from August 21–24, 2003 over the South Course at Firestone Country Club in Akron, Ohio. It was the fifth WGC-NEC Invitational tournament, and the second of four World Golf Championships events held in 2003.
α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine or as catecholamphetamine, is a research chemical of the catecholamine and amphetamine families. Its bis-glutathionyl metabolite is slightly neurotoxic when directly injected into the brain's ventricles.
3,4-dichloromethylphenidate is a potent stimulant drug from the phenidate class, closely related to methylphenidate. It acts as a potent serotonin-norepinephrine-dopamine reuptake inhibitor, with a long duration of action. It has been sold online as a designer drug.
3,4-Ethylidenedioxyamphetamine (EIDA) is a substituted derivative of 3,4-methylenedioxyamphetamine (MDA), which was developed by David Nichols and coworkers, in the course of research to determine the bulk tolerance around the benzodioxole portion of the MDA molecule. EIDA was found to produce similar effects to MDA in animals but with less than half the potency, while the isopropylidenedioxy derivative did not substitute for MDA and instead had sedative and convulsant effects. This shows limited bulk tolerance at this position and makes it likely the activity of EIDA will reside primarily in one enantiomer, although only the racemic mix has been studied as yet.
3,4-Dimethylmethcathinone (3,4-DMMC) is a stimulant drug first reported in 2010 as a designer drug analogue of mephedrone, apparently produced in response to the banning of mephedrone, following its widespread abuse in many countries in Europe and around the world. 3,4-DMMC has been seized as a designer drug in Australia. In vitro, 3,4-DMMC was shown to be a monoamine transporter substrate that potently inhibits norepinephrine and serotonin reuptake, and to a lesser extent dopamine reuptake.
3,4-Dichloroamphetamine (DCA), is an amphetamine derived drug invented by Eli Lilly in the 1960s, which has a number of pharmacological actions. It acts as a highly potent and selective serotonin releasing agent (SSRA) and binds to the serotonin transporter with high affinity, but also acts as a selective serotonergic neurotoxin in a similar manner to the related para-chloroamphetamine, though with slightly lower potency. It is also a monoamine oxidase inhibitor (MAOI), as well as a very potent inhibitor of the enzyme phenylethanolamine N-methyl transferase which normally functions to transform noradrenaline into adrenaline in the body.
The 2017 WGC-Bridgestone Invitational was a professional golf tournament held August 3–6 on the South Course of Firestone Country Club in Akron, Ohio. It was the 19th WGC-Bridgestone Invitational tournament, and the third of the World Golf Championships events in 2017.
The 2018 WGC-Bridgestone Invitational was a professional golf tournament held August 2–5 on the South Course of Firestone Country Club in Akron, Ohio. It was the 20th WGC-Bridgestone Invitational tournament, and the third of the World Golf Championships events in 2018.
The 2019 WGC-FedEx St. Jude Invitational was a professional golf tournament held July 25–28 at TPC Southwind in Memphis, Tennessee. It was the 21st WGC Invitational tournament, and the third of the World Golf Championships events in 2019. It was the first time the event had been held in Tennessee, having previously been based at Firestone Country Club in Ohio.
