amphetamine Amphetamine: A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.. 1-phenylpropan-2-amine : A primary amine that is isopropylamine in which a hydrogen attached to one of the methyl groups has been replaced by a phenyl group.. amphetamine : A racemate comprising equimolar amounts of (R)-amphetamine (also known as levamphetamine or levoamphetamine) and (S)-amphetamine (also known as dexamfetamine or dextroamphetamine. | 2.08 | 1 | 0 | primary amine | |
