2-MDP - Dissociative anaesthetic, NMDAN-methyl-D-aspartate receptor. NMDA antagonists are often dissociatives. antagonistA substance that interferes with or inhibits the physiological action of another., simlar effects to PCP in animals, (-) isomerEach of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties. is active. Roughly 1/3rd potency of amphetamine by weight. Lasts over 24 hours.

2C-B-BZP - Benzylpiperazine base with ring-sub pattern of 2c-b. Not a phenethylaminePhenethylamine (PEA) is a natural monoamine alkaloid, trace amine, and psychoactive drug with stimulant effects. In the mammalian central nervous system, phenethylamine is believed to function as a neuromodulator or neurotransmitter., doesn't produce psychedelic effects. Lasts 3-6 hours. Was sold in Japan in "smartshops"

A-366/833 - AgonistA substance that initiates a physiological response when combined with a receptor. at neural nicotinic acetylcholine receptors selective for α4β2 subtype. Been researched as an analgesic. Hasn't passed clinical trials.

A-84/543 ^ That and is used as the "standard" for this family of compounds.

2-Acetoxycocaine - Quicker onset than Cocaine. Four fold increase over cocaine in binding potency for dopamineA neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system.. And 35 fold enhanced affinity for the norepinephrine. Reduced selectivity for serotoninA monoamine neurotransmitter, biochemically derived from tryptophan, that is primarily found in the gastrointestinal (GI) tract, platelets, and central nervous system (CNS) of humans and animals. It is a well-known contributor to feelings of well-being.. Interesting structure.

Adrafinil - Prodrug of Modafinil, unregulated in the US. 1 hour half life.

AL-1095 - Centrally acting, comparable efffects to amp. developed by Bristol in the 70's.

Altinicline (SIB-1508Y) agonistA substance that initiates a physiological response when combined with a receptor. at neural nicotinic acetylcholine receptors similar to A-366. Releases DopamineA neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system. and Acetylcholine in both rodent and primate models. Progressed into Phase 2 clinical trials for Parkinson's.

Amfepramone - Diethylcathinone. By itself lacks any affinity for monoamine transporters and functions as a prodrug to ethcathinone. Very weak dopaminergic and serotonergic. 10-20x stronger on norepinephrine in comparison. Basically can be considered NRA's. Is currently Schedule IV in the United States. Class C drug in the UK. Apparently known as "tombstones" in the UK.

2-amino-1,2-dihydronaphthalene - Also known as 2-AD, rigid analogue of phenylisobutylamine and substitutes amphetamine for it in rat discrimination tests, 1/4th the potency. Closely related to 2-aminotetralin.

2-Aminoindane - 2-AI(RC) Psychoactive compound. Rigid analogue of amphetamine.

5-(2-aminopropyl)indole - 5-IT(RC) indole derivative. Preparation was first reported in 1962 by Albert Hofmann. Positional isomerEach of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties. of AMT. Closer chemically resembles

Phethylamines like 5-apb and the likes. Falls under the Analog act in the US with AMT.

6-(2-Aminopropyl)indole - ^. But it has been shown to increase hemoglobin levels in the bloodstream.

Aminorex - Known by many other names. Anorectic stimulant. Is classed within the 2-amino-5-aryl oxazoline class. Closely related to 4-methylaminorex. Shown to have locomotor stimulant effects, lying midway between dextro-amp and Meth. Attributed to the release of cathecholamines. Retired from the market after it was found to result in pulmonary hypertension.

2-Aminotetralin - (2-AT) consiting of a tetralin group combined with an anime. Rigid analogue of phenylisobutylamine. Fully substitutes for D-Amp in rat discrimination tests.

Although at 1/8th the potenct. Inhibits the reuptake of serotoninA monoamine neurotransmitter, biochemically derived from tryptophan, that is primarily found in the gastrointestinal (GI) tract, platelets, and central nervous system (CNS) of humans and animals. It is a well-known contributor to feelings of well-being. and norepinephrine. Likely induces their release as well. Also likely to act of DopamineA neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system. on account of the D-Amp.
