This is a list ofaminorex analogues, also known assubstituted 2-amino-5-aryloxazolines. Aminorex itself is astimulant drug with a 5-phenyl-2-amino-oxazoline structure. It was developed in the 1960s as ananorectic,[1][2][3] but withdrawn from sale after it was discovered that extended use producedpulmonary hypertension, often followed byheart failure, which resulted in a number of deaths.[4] Adesigner drug analogue4-methylaminorex appeared on the illicit market in the late 1980s but did not attract significant popularity due to its steep dose-response curve and tendency to produceseizures.[5][6][7][8]Pemoline, the 4-keto derivative of aminorex, had been discovered several years earlier,[9] and derivatives of this type appeared to be effective stimulants with comparatively low toxicity.[10][11] Pemoline was sold for around 25 years as a therapy forADHD and relief offatigue, before being withdrawn from the market in 2005 because of rare but serious cases ofliver failure.[12][13][14][15] More recently in around 2014 another derivative4,4'-dimethylaminorex started to be sold illicitly, but again swiftly lost popularity due to a spate of fatal overdose cases.[16][17][18] A number of related compounds are known, and new derivatives have continued to appear on the designer drug market.[19][20][21][22][23][24]
