variations of the neurotransmitter histamine led to mixtures of alpha,beta-dimethylhistamines as well as to the corresponding pure optical isomers. One of these isomers, namely (alpha R,beta S)-alpha,beta-dimethylhistamine, proved to be a highly potent H3 receptor agonist with exceptional receptor selectivity. The absoluteconfiguration of the compound was determined by X-ray structure analysis of its
