Alphacetylmethadol (INN), aka α-acetylmethadol (AAM), is a synthetic opioid analgesic. Its levorotary enantiomer, levacetylmethadol, is an FDA-approved treatment for opioid addiction. Alphacetylmethadol is very similar in structure to methadone, a widely-prescribed treatment for opioid addiction. In the United States, it is a Schedule I controlled substance under the Controlled Substances Act with an ACSCN of 9603 and a 2013 annual manufacturing quota of 2 grams. Studies in rats indicate that alphacetylmethadol also evokes the heroin-like discriminative stimulus effects.

Diethylaminoethoxyhexestrol is a coronary dilating agent, approved for the treatment of angina in 1958 and marketed under tradename Coralgil. Diethylaminoethoxyhexestrol was withdrawn from the market because of drug-related phospholipidosis in liver, spleen and other tissues. Studies indicate that lipidosis is caused by the accumulation of the drug in lysosomes and inhibition of phospholipase A.

Aminorex is an anorectic stimulant drug. Aminorex inhibits norepinephrine and dopamine transporters with IC50 of 0.33 and 0.85 uM. It was briefly available as an appetite suppressant in the 1960s in Switzerland, Germany, and Austria, but was found to cause pronounced vasoconstriction in the pulmonary vasculature, and was withdrawn from the market in 1972 due to several cases of fatal and life-threatening pulmonary hypertension. In the USA aminorex is an illegal schedule I drug.

Hydroxytamoxifen (Afimoxifene) is an active metabolite of tamoxifen exerting estrogen receptor modulatory function. In addition, hydroxytamoxifen binds to regulates transcriptional activity of the estrogen-related receptor gamma.
