<unk>  is a synthetic, nonsteroidal, orally active estrogen that was never marketed. The reaction of estradiol or estrone with potassium hydroxide, a strong base, results in<unk>  as a degradation product, which retains high estrogenic activity, and this reaction was how the drug was discovered, in the late 1930s. The drug is a highly active and potent estrogen by the oral or subcutaneous route. The reaction of equilenin or dihydroequilenin with potassium hydroxide was also found to produce bisdehydrodoisynolic<unk> , the levorotatory isomer of which is an estrogen with an "astonishingly" high degree of potency, while the dextrorotatory isomer is inactive.<unk>  was named after Edward Adelbert Doisy, a pioneer in the field of estrogen research and one of the discoverers of estrone.<unk>  is the parent compound of a group of synthetic, nonsteroidal estrogens with high oral activity. The synthetic, nonsteroidal estrogens methallenestril, fenestrel, and carbestrol were all derived from<unk>  and are seco-analogues of the compound. Doisynoestrol, also known as fenocycline, is cis-bisdehydrdoisynolic<unk>  methyl ether, and is another estrogenic derivative.
