Estradiol 17β-tetrahydropyranyl ether

Estradiol 17β-tetrahydropyranyl ether is a synthetic estrogen and estrogen ether which was never marketed.[1][3][4][2][5][6][7] It has been reported to possess improved oral activity relative to estradiol.[1][3][4] One study in animals found that it had 15 times the oral activity of estradiol.[1][3]
