N-Ethyl-5-trifluoromethyl-2-aminoindane (ETAI) is a psychoactive drug and research chemical with putative entactogenic effects. It functions as a selective serotonin releasing agent (SSRA). ETAI is the aminoindane analogue of fenfluramine and is approximately 50% as neurotoxic in comparison. [1]

The drug combination fenfluramine/phentermine, usually called fen-phen, was an anti-obesity treatment in the early 1990s that utilized two anorectics. Fenfluramine was marketed by American Home Products as Pondimin, but was shown to cause potentially fatal pulmonary hypertension and heart valve problems, which eventually led to its withdrawal in 1997 and legal damages of over $13 billion. Phentermine was not shown to have harmful effects.

Fenfluramine, sold under the brand name Fintepla, is a serotonergic medication used for the treatment of seizures associated with Dravet syndrome and Lennox–Gastaut syndrome. It was formerly used as an appetite suppressant in the treatment of obesity, but was discontinued for this use due to cardiovascular toxicity before being repurposed for new indications. Fenfluramine was used for weight loss both alone under the brand name Pondimin and in combination with phentermine under the brand name Fen-Phen among others.

<span class="mw-page-title-main">Norfenfluramine</span> Chemical compound

Norfenfluramine, or 3-trifluoromethylamphetamine, is a never-marketed drug of the amphetamine family that behaves as a serotonin and norepinephrine releasing agent and potent 5-HT2A, 5-HT2B, and 5-HT2C agonist. The action of norfenfluramine on 5-HT2B receptors on heart valves leads to a characteristic pattern of heart failure following proliferation of cardiac fibroblasts on the tricuspid valve, known as cardiac fibrosis. This side effect led to the withdrawal of fenfluramine as an anorectic agent worldwide, and to the withdrawal of benfluorex in Europe, as both fenfluramine and benfluorex form norfenfluramine as an active metabolite. It is a human TAAR1 agonist.

In pharmacology, an indirect agonist or indirect-acting agonist is a substance that enhances the release or action of an endogenous neurotransmitter but has no specific agonist activity at the neurotransmitter receptor itself. Indirect agonists work through varying mechanisms to achieve their effects, including transporter blockade, induction of transmitter release, and inhibition of transmitter breakdown.

<i>para</i>-Chloroamphetamine Chemical compound

para-Chloroamphetamine (PCA), also known as 4-chloroamphetamine (4-CA), is a substituted amphetamine and monoamine releaser similar to MDMA, but with substantially higher neurotoxicity, thought to be due to the unrestrained release of both serotonin and dopamine by a metabolite. It is used as a neurotoxin by neurobiologists to selectively kill serotonergic neurons for research purposes, in the same way that 6-hydroxydopamine is used to kill dopaminergic neurons.

5-Methoxy-6-methyl-2-aminoindane (MMAI) is a drug developed in the 1990s by a team led by David E. Nichols at Purdue University. It acts as a non-neurotoxic and highly selective serotonin releasing agent (SSRA) and produces entactogen effects in humans. It has been sold as a designer drug and research chemical online since 2010.

<span class="mw-page-title-main">5-IAI</span> Chemical compound

5-Iodo-2-aminoindane (5-IAI) is a drug which acts as a releasing agent of serotonin, norepinephrine, and dopamine. It was developed in the 1990s by a team led by David E. Nichols at Purdue University. 5-IAI fully substitutes for MDMA in rodents and is a putative entactogen in humans. Unlike related aminoindane derivatives like MDAI and MMAI, 5-IAI causes some serotonergic neurotoxicity in rats, but is substantially less toxic than its corresponding amphetamine homologue pIA, with the damage observed barely reaching statistical significance.

<span class="mw-page-title-main">Levofenfluramine</span> Chemical compound

Levofenfluramine (INN), or (−)-3-trifluoromethyl-N-ethylamphetamine, also known as (−)-fenfluramine or (R)-fenfluramine, is a drug of the amphetamine family that, itself (i.e., in enantiopure form), was never marketed. It is the levorotatory enantiomer of fenfluramine, the racemic form of the compound, whereas the dextrorotatory enantiomer is dexfenfluramine. Both fenfluramine and dexfenfluramine are anorectic agents that have been used clinically in the treatment of obesity (and hence, levofenfluramine has been as well since it is a component of fenfluramine). However, they have since been discontinued due to reports of causing cardiovascular conditions such as valvular heart disease and pulmonary hypertension, adverse effects that are likely to be caused by excessive stimulation of 5-HT2B receptors expressed on heart valves.
