Amphetamine EMIT—Structure Versus Reactivity

Abstract

Over 60 different amphetamine-related amines were analyzed by EMIT (Enzyme Multiplied Immunoassay Technique) at several different concentrations. An attempt is made to relate structural differences to the affinity of the compounds for the EMIT amphetamine antibody. The effects of substituent placement on the amphetamine molecule are studied. Addition of a single alkyl group to the nitrogen of amphetamine increased reactivity, whereas all other structural changes had the reverse effect, decreasing reactivity.
