RU-486
In April 1980, as part of a formal research project at Roussel-Uclaf for the development of 糖皮质激素受体 受体拮抗剂s, chemist Georges Teutsch synthesized 美服培酮 (RU-38486, the 38,486th compound synthesized by Roussel-Uclaf from 1949 to 1980; shortened to RU-486); which was discovered to also be a 孕酮受体 antagonist. In October 1981, endocrinologist , a consultant to Roussel-Uclaf, arranged tests of its use for in eleven women in 瑞士 by gynecologist Walter Herrmann at the 日内瓦大学's Cantonal Hospital, with successful results announced on April 19, 1982. On October 9, 1987, following worldwide clinical trials in 20,000 women of mifepristone with a 前列腺素 analogue (initially 硫前列酮 or 吉美前列素, later 米索前列醇) for medical abortion, Roussel-Uclaf sought approval in France for their use for medical abortion, with approval announced on September 23, 1988.
墮胎產品
1988年10月21日，為了回應反墮胎的抗議和大多數 (54.5%) 所有者HoechstAG的擔憂，Roussel-Uclaf高管和董事會以16票對4票決定於1988年10月26日宣布停止米非司酮的分銷
兩天後，法國政府下令Roussel-Uclaf重新分發米非司酮。法國衛生部長 解釋說：「我不能允許因墮胎爭論剝奪婦女代表醫學進步的產品。從政府批准該藥物的那一刻起，RU-486立即已成為女性的財產，這不僅僅是一家製藥公司的財產。」 and in 瑞典 in September 1992, but until his retirement in late April 1994, Hoechst AG chairman Wolfgang Hilger, a devout 天主教會, blocked any further expansion in availability. On May 16, 1994, Roussel-Uclaf announced that it was donating without remuneration all rights for medical uses of mifepristone in the U.S. to the , which subsequently licensed mifepristone to , a new single-product company immune to antiabortion boycotts, which won 美国食品药品监督管理局 approval as Mifeprex on September 28, 2000.
On April 8, 1997, after buying the remaining 43.5% of Roussel-Uclaf stock in early 1997, Hoechst AG ($30 billion annual revenue) announced the end of its manufacture and sale of Mifegyne ($3.44 million annual revenue) and the transfer of all rights for medical uses of mifepristone outside of the U.S. to Exelgyn S.A., a new single-product company immune to antiabortion boycotts, whose CEO was former Roussel-Uclaf CEO Édouard Sakiz. In 1999, Exelgyn won approval of Mifegyne in 11 additional countries, and in 28 more countries over the following decade.
