L-Norpseudoephedrine is a psychostimulant drug of amphetamine family, first isolated from an Ephedra species. It is one of the two enantiomers of norpseudoephedrine, less potent that D-Norpseudoephedrine. L-Norpseudoephedrine is a norepinephrine and dopamine releasing agent, and has thermogenic and anorectic effect.

2,5-Dimethoxy-4-iodoamphetamine (4-iodo-2,5-dimethoxyphenylisopropylamine or DOI), a psychedelic drug and hallucinogen has high affinity and is a potent agonist for each of the 5-HT2 receptor subtypes: 5-HT2A, 5-HT2B, and 5-HT2C. DOI's effects have been compared to LSD. DOI has a stereo center and R-(−)-DOI is the more active stereoisomer. It was shown, that R-(−)-DOI via 5-HT2A receptor could inhibit a variety of TNF-alpha-mediated proinflammatory markers, including intracellular adhesion molecule 1 (ICAM-1), vascular adhesion molecule 1 (VCAM-1), and interleukin (IL)-6 gene expression. It is known, that TNF-alpha-mediated inflammatory pathways have been strongly implicated in a number of diseases, including atherosclerosis, rheumatoid arthritis, psoriasis, type II diabetes, depression, schizophrenia, and Alzheimer's disease. Thus, because (R)-DOI can significantly inhibit the effects of TNF-alpha many hours after the administration of TNF-alpha, potential therapies could be aimed not only at preventing inflammation but at also treating the inflammatory injury that has already occurred or is ongoing.

SCH-23390 is a potent and selective antagonist of the dopamine-1 and dopamine-5 receptors (Ki = 0.2 and 0.3 nM respectively). It was found to prevent death from d-amphetamine overdose in rats and has also been investigated as a potential treatment for Parkinson's Disease and Bipolar Disorder. A single clinical trial was conducted in healthy humans where SCH-23390 induced akathisia (motor restlessness). Preclinical and clinical trials as therapeutic have been discontinued due to side-effects and lack of efficacy. However, it should be noted that a C11 radiolabeled version of the compound has been synthesized and used as a PET imaging probe for the study of Parkinson's Disease and Huntington's Disease.
