2-Aminoindane (2-AI) is an aminoindane and research chemical with applications in neurologic disorders and psychotherapy that has also been sold as a designer drug. [1] It acts as a selective substrate for NET and DAT. [2] [3]

Contents

Therapeutic and illicit uses

Synthetic aminoindanes were originally developed in the context of anti-Parkinsonian drugs as a metabolite of rasagiline and as a tool to be used in psychotherapy. Deaths related to their toxic effects have been observed both in the laboratory in animal studies and in clinical encounters. [4]

2-AI is a rigid analogue of amphetamine and partially substitutes for it in rat drug discrimination tests. [5] [6] Other related homologues and rigid analogues of amphetamine include 2-aminotetralin (2-AT), 2-amino-1,2-dihydronapthalene (2-ADN), 1-naphthylaminopropane (1-NAP), 2-naphthylaminopropane (2-NAP), 1-phenylpiperazine (1-PP), 6-AB Tooltip 6-amino-6,7,8,9-tetrahydro-5H-benzocycloheptene, and 7-AB Tooltip 7-amino-6,7,8,9-tetrahydro-5H-benzocycloheptene. [6] [5] [7]

Chemical derivatives

There are a number of notable derivatives of 2-aminoindane that exist, including:

A number of notable derivatives of 1-aminoindan, a positional isomer of 2-aminoindan, also exist, such as rasagiline and ladostigil, among others.

Jimscaline, 2CB-Ind, and AMMI are derivatives of 1-aminomethylindane, an indane- and amine-containing compound related to 1-aminoindan.

China

As of October 2015 2-AI is a controlled substance in China. [9]

Finland

Scheduled in the "Government decree on psychoactive substances banned from the consumer market". [10]

Sweden

Sweden's public health agency suggested classifying 2-AI as a hazardous substance, on June 24, 2019. [11]

United States

2-Aminoindane is not scheduled at the federal level in the United States, [12] but may be considered an analog of amphetamine, in which case purchase, sale, or possession could be prosecuted under the Federal Analog Act.

<span class="mw-page-title-main">Monoamine releasing agent</span> Class of compounds

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.

(<i>R</i>)-1-Aminoindan Major metabolite of rasagiline

(R)-1-Aminoindan ((R)-1-AI; developmental code name TVP-136 or TV-136), or (R)-1-aminoindane, is the major metabolite of the selective MAO-B inhibitor and antiparkinsonian agent rasagiline ((R)-N-propargyl-1-aminoindan). In contrast to rasagiline, it lacks significant monoamine oxidase inhibition. In addition, unlike selegiline and its amphetamine metabolites, it lacks monoamine reuptake-inhibiting and -releasing activities and associated amphetamine-like psychostimulant effects. However, (R)-1-aminoindan retains neuroprotective effects and certain other activities.

1-Aminoindane (1-AI), also known as 1-aminoindan, 1-indanylamine, or 1-indanamine, is an aminoindane. It is a positional isomer of 2-aminoindane. A variety of notable derivatives of 1- and 2-aminoindane are known. The (R)-enantiomer of 1-aminoindan, (R)-1-aminoindan, is pharmacologically active and is an active metabolite of the antiparkinsonian agent rasagiline.
