It was early recognized that the alkaloids were complex amines or ammonia derivatives.
In fact, there are specific postnatal critical periods and developmental sequences for the appearance of the biogenic amines dopamine and noradrenaline.
The active compounds share a common structural motif : a protonatable amine moiety separated from an ionized sulfonate moiety by 2 or 3 methylene groups.
In the other isomers, where the two groups are linked together, the carbonyl group attracts the electrons, which destabilizes the protonated amine.
Biogenic amines were selected on the basis of their effects during frequency of movement assays.
Table 2 depicts the data for the biogenic amines and their metabolites under basal and separation conditions.
The major inactivation of biogenic amines is performed by monoamine oxidase, an enzyme located solely in mitochondria.
