Alpha-N,N-Trimethyltryptamine α,N,N-Trimethyltryptamine (α,N,N-TMT, α-TMT, ATMT) is a psychoactive drug of the tryptamine chemical class which acts as a psychedelic hallucinogen. It is similar in structure to the other psychedelics of the tryptamine class such as dimethyltryptamine (DMT) and α-methyltryptamine (α-MT).α-TMT has been animal tested in comparison with α-MT, and was found to produce similar effects to α-MT but with only around half the potency. Anecdotal reports from human users suggest that it produces psychedelic effects similar to those of other tryptamine derivatives when taken orally at a dose of around 80–120 mg, however it does not appear to have been widely sold or used, and its safety profile has not been studied.

Alpha-Ketobutyric acid α-Ketobutyric acid is a product of the lysis of cystathionine. It is also one of the degradation products of threonine, produced by the catabolism of the amino acid by threonine dehydratase. It is also produced by the degradation of homocysteine and the metabolism of methionine.α-Ketobutyric acid is transported into the mitochondrial matrix, where it is converted to propionyl-CoA by branched-chain alpha-keto acid dehydrogenase complex. Further mitochondrial reactions produce succinyl-CoA. This is first through the enzyme mitochondria Propionyl-CoA carboxylase with biotin as a cofactor to produce (S)-methylmalonyl-CoA. This is subsequently converted to (R)-methylmalonyl-CoA by mitochondrial methylmalonyl-CoA epimerase. Finally, mitochondrial methylmalonyl-CoA mutase with cofactor adenosylcobalamin produces succinyl-CoA which enters the citric acid cycle.

α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine (3,4-DHA), is a neurotoxin and research chemical of the catecholamine and amphetamine chemical classes. The basis of this idea is in the observation that MDA and MDMA may not themselves be responsible for their neurotoxicity, as an intracerebroventricular injection (injection directly into the brain itself) does not appear to cause neurotoxicity. While many studies cite excitotoxicity, or oxidative stress as likely mechanisms, which may be an effect of the chemical itself, this has led to the search for other mechanisms for the observed toxicity of serotonin neurons and subsequent reduction in 5-HT (Serotonin) and 5-HIAA (its major metabolite in the body) in vivo following administration. A common theory follows that a metabolite in the periphery must be responsible, and several have been cited as responsible. Although, alpha-methyldopamine is widely cited as the source of this neurotoxicity in a number of lay sources, McCann, et al. (1991), demonstrated that the major metabolites alpha-methyldopamine (α-Me-DA) and 3-O-methyl-α-methyldopamine (3-O-Me-α-MeDA) did not produce neurotoxicity.It was first demonstrated, in 1978, by Conway, et al. and possibly others that, while alpha-methyldopamine caused acute decreases in the levels of neuronal dopamine, in some areas of the brain in excess of 75%, levels returned to baseline within 12 hours, indicating that alpha-methyldopamine would not be responsible for the toxic effects observed.However, the story complicates as alpha-methyldopamine readily oxidizes to the o-quinone and reacts with endogenous antioxidants in the body, such as glutathione (GSH). It was demonstrated by Miller, et al. (1997), that 5-(glutathion-S-yl)-alpha-methyldopamine and 5-(N-acetylcystein-S-yl)-alpha-methyldopamine produced similar effects to the parent compound, but did not induce neurotoxicity. Another related compound however, 2,5-bis-(glutathion-S-yl)-alpha-methyldopamine, did in fact induce neurotoxicity, providing initial evidence that this metabolite may be the source of neuronal toxicity following the administration of MDA and MDMA, and the subsequent reduction in 5-HT (Serotonin) axons.

Alpha-Pyrrolidinopropiophenone α-Pyrrolidinopropiophenone (α-PPP), is a stimulant drug. It is similar in structure to the appetite suppressant diethylpropion and has analogous effects in animals. Little is known about this compound, but it has been detected by laboratories in Germany as an ingredient in "ecstasy" tablets seized by law enforcement authorities. This drug has been found to produce stimulant effects in animals and presumably also produces these effects in humans, based on the context in which it has been found.α-PPP is illegal in the UK under the blanket ban on substituted cathinones, and due to its structural similarity to illegal drugs such as methcathinone and pyrovalerone it might be considered a controlled substance analogue in some countries such as the USA, Australia and New Zealand. Analogues of α-PPP such as pyrovalerone and MDPV have been more widely used and are presumed to be more potent and addictive than α-PPP itself. Structure-activity relationships of these drugs suggest that a variety of ring-substituted analogues are likely to be potential drugs of abuse, and stimulant activity has been found for analogues with between 3 and 6 carbon atoms in the alkyl chain.

Alpha-Methylserotonin α-Methylserotonin (αMS), also known as α-methyl-5-hydroxytryptamine (α-methyl-5-HT) or 5-hydroxy-α-methyltryptamine (5-HO-αMT), is a tryptamine derivative closely related to the neurotransmitter serotonin (5-HT). It acts as a non-selective serotonin receptor agonist and has been used extensively in scientific research to study the function of the serotonin system.Unlike serotonin, αMS is not metabolized by monoamine oxidase on account of the α-methyl substituent blocking the enzyme's access to the amine. As a result, it has a much longer half-life in comparison. Similarly to serotonin however, αMS poorly crosses the blood-brain-barrier due to its free hydroxyl group, and thus has only weak or no central effects when administered peripherally.α-Methyltryptophan (αMTP) is a prodrug to αMS which does cross the blood-brain-barrier and thus efficiently delivers αMS into the central nervous system. As a result, αMTP acts as an orally bioavailable false or substitute neurotransmitter for serotonin, and has been suggested as a possible therapeutic agent in the treatment of disorders where serotonin is deficient. The O-methylated analogue of αMS, 5-MeO-αMT, also readily enters the brain and could be used for this purpose as well.

Alpha-Pyrrolidinobutiophenone α-Pyrrolidinobutiophenone (α-PBP) is a stimulant compound developed in the 1960s which has been reported as a novel designer drug. It can be thought of as the homologue lying between the two better known drugs α-PPP and α-PVP.

Alpha-Aminobutyric acid α-Aminobutyric acid (AABA), also known as homoalanine in biochemistry, is a non-proteinogenic alpha amino acid with chemical formula C4H9NO2. The straight two carbon side chain is one carbon longer than alanine, hence the prefix homo-.Homoalaine is biosynthesised by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis. It is used by nonribosomal peptide synthases.

Alpha-Melanocyte-stimulating hormone α-Melanocyte-stimulating hormone (α-MSH) is an endogenous peptide hormone and neuropeptide of the melanocortin family, with a tridecapeptide structure and the amino acid sequence Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2. It is the most important of the melanocyte-stimulating hormones (MSHs) (also known as melanotropins) in stimulating melanogenesis, a process that in mammals (including humans) is responsible for pigmentation primarily of the hair and skin. It also plays a role in feeding behavior, energy homeostasis, sexual activity, and protection against ischemia and reperfusion injury.α-MSH is a non-selective full agonist of the melanocortin receptors MC1 (Ki = 0.230 nM), MC3 (Ki = 31.5 nM), MC4 (Ki = 900 nM), and MC5 (Ki = 7160 nM), but not MC2 (which is exclusive for adrenocorticotropic hormone (ACTH)). Activation of the MC1 receptor is responsible for its effect on pigmentation, whereas its regulation of appetite, metabolism, and sexual behavior is mediated through both the MC3 and MC4 receptors.It is generated as a proteolyic cleavage product from ACTH (1-13), which is in turn a cleavage product of proopiomelanocortin (POMC).A few synthetic analogues of α-MSH have been investigated as medicinal drugs due to their photoprotective effects against ultraviolet (UV) radiation from the sun. They include afamelanotide (melanotan) and melanotan II, the former of which being in phase-III clinical trials in the United States. Bremelanotide, another analogue of α-MSH, is currently under development not as a photoprotective agent, but instead for the treatment of sexual dysfunction. All of these drugs have significantly greater potencies than α-MSH, along with improved pharmacokinetics and distinctive selectivity profiles.

Alpha-Parinaric acid α-Parinaric acid is a conjugated polyunsaturated fatty acid. Discovered by Tsujimoto and Koyanagi in 1933, it contains 18 carbon atoms and 4 conjugated double bonds. The repeating single bond-double bond structure of α-parinaric acid distinguishes it structurally and chemically from the usual "methylene-interrupted" arrangement of polyunsaturated fatty acids that have double-bonds and single bonds separated by a methylene unit (−CH2−). Because of the fluorescent properties conferred by the alternating double bonds, α-parinaric acid is commonly used as a molecular probe in the study of biomembranes.
