Diethylstilbestrol dipropionate

Diethylstilbestrol dipropionate (DESDP) (brand names Agostilben, Biokeral, Clinestrol, Cyclen, Estilbin, Estril, Neobenzoestrol, Orestol, Oroestrol, Ostregenin, Prostilbene, Stilbestriol DP, Stilboestrolum Dipropionicum, Stilboestrol, Synestrin, Willestrol, others), or diethylstilbestrol dipropanoate, also known as stilboestrol dipropionate (BANMTooltip British Approved Name), is a synthetic nonsteroidal estrogen of the stilbestrol group that was formerly marketed widely throughout Europe.[1][2] It is an ester of diethylstilbestrol with propionic acid,[1] and is more slowly absorbed in the body than diethylstilbestrol.[3] The medication has been said to be one of the most potent estrogens known.[4]

There is no doubt that the conversion of the endometrium with injections of both synthetic and native estrogenic hormone preparations succeeds, but the opinion whether native, orally administered preparations can produce a proliferation mucosa changes with different authors. PEDERSEN-BJERGAARD (1939) was able to show that 90% of the folliculin taken up in the blood of the vena portae is inactivated in the liver. Neither KAUFMANN (1933, 1935), RAUSCHER (1939, 1942) nor HERRNBERGER (1941) succeeded in bringing a castration endometrium into proliferation using large doses of orally administered preparations of estrone or estradiol. Other results are reported by NEUSTAEDTER (1939), LAUTERWEIN (1940) and FERIN (1941); they succeeded in converting an atrophic castration endometrium into an unambiguous proliferation mucosa with 120–300 oestradiol or with 380 oestrone.
