In 1951, Djerassi, Miramontes and Rosenkranz [29] converted 19-nortestosterone into 19-norandrostenedione (XIV) and thence into norethindrone (19-norethisterone) (XVIII). Two years later, Colton [30] prepared norethynodrel (XIX). These two 19-nor steroids achieved immediate success as orally active progestagens. In retrospect, the enhanced biological potency of (XVIII) over ethisterone (XVI) is not surprising as 19-nor steroids form the biogenetic link between the androgens and the quantitatively more potent oestrogens. At the time, however, the results were baffling. [Pg.179]

The oral contraceptive norethisterone (norethindrone, 129) has been shown to produce the 4/ ,5/ -epoxide (130) over a 30 min irradiation at 300 nm in aqueous buffer at pH 7.4. The possibility that this reactive species is responsible for the non-dermatological side-effects of oral contraceptives containing norethisterone was noted. One serious systemic effect of the drug which could be caused... [Pg.77]
