4-Amino-1-butanol, or 4-aminobutanol, also known as 4-hydroxybutylamine, is an alkanolamine and an analogue and precursor of the neurotransmitter γ-aminobutyric acid (GABA).[1][2][3][4]
The structural relation of 1,4-butanediol (1,4-BD) to γ-hydroxybutyric acid (GHB) is analogous to the relation of 4-amino-1-butanol to GABA.[1] 1,4-BD is a known prodrug of GHB which is converted into it through the actions of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH).[5][6] γ-Hydroxybutyraldehyde (GHBAL) is an intermediate in this pathway,[5][6] whereas the analogous intermediate structure for 4-amino-1-butanol and GABA is γ-aminobutyraldehyde (GABAL).[7][8][9] Similar to the conversion of 1,4-BD into GHB, 4-amino-1-butanol is converted into GABAL by aldehyde reductase (ALR) and GABAL is converted into GABA by ALDH.[2][7][8][9]

In biological mixtures γ-aminobutyraldehyde may be alternatively oxidized by aldehyde dehydrogenases (EC 1.2.1.3) to γ-aminobutyric acid (GABA) (11—13). The formation of 4-amino-1-butanol is also possible through reduction by aldehyde dehydrogenase and/or alcohol dehydrogenase (13,14), thus preventing cyclization. Other fates of putrescine in biological mixtures include the acetylation to acetylputrescine by an N-acetyltransferase and then oxidation by monoamine oxidase (EC 1.4.3.4) (11,17).

Alternate pathways of GABA synthesis from putrescine and other polyamines have also been reported [207–211]. Here, γ-aminobutyraldehyde, an intermediate from polyamine degradation reaction via combined activities of diamine oxidase (DAO, E.C. 1.4.3.6) and 4-aminobutyraldehyde dehydrogenase (ABALDH), leads to the synthesis of GABA [205,212,213]. In response to abiotic stresses, GABA is also reported to be synthesized from proline via D1-pyrroline intermediate formation [47,205,214] and also by a nonenzymatic reaction [214]. However, GABA synthesis from polyamine pathways is minor in the brain, [215] although they play a significant role in the developing brain [216] and retina [217]. But GABA can be formed from putrescine in the mammalian brain [218].

MAO also catalyses the deamination of a natural brain constituent, monoacetyl-putrescine, producing y-acetylaminobutyraldehyde, which in turn participates in the formation of brain GABA [13].
