網頁2011年4月19日 · Abstract. Thalidomide was a widely used drug in the late 1950s and early 1960s for the treatment of nausea in pregnant women. It became apparent in the 1960s th Josef Warkany, one of the founders of the Teratology Society, doubted in … 網頁2024年2月17日 · The turning point in the regulation of chiral drugs was the thalidomide (2-(2,6-dioxopiperidin-3-yl)isoindole-1,3-dione) tragedy in the 1960s. Thalidomide, a glutamic acid derivative, was used as a racemate for its sedative-hypnotic effects but also for treating morning sickness in pregnant women.

It was marketed as a racemic mixture: in other words, a 50:50 mixture of both enantiomers. Let’s try to determine the stereochemical configuration of the enantiomer on the left. Of the four bonds to the chiral center, the #4 priority is hydrogen.
