ChEBI: Diethylstilbestrol is an olefinic compound that is trans-hex-3-ene in which the hydrogens at positions 3 and 4 have been replaced by p-hydroxyphenyl groups. It has a role as an antineoplastic agent, a carcinogenic agent, a xenoestrogen, an EC 3.6.3.10 (H(+)/K(+)-exchanging ATPase) inhibitor, an antifungal agent, an endocrine disruptor, an EC 1.1.1.146 (11beta-hydroxysteroid dehydrogenase) inhibitor, an autophagy inducer and a calcium channel blocker. It is a polyphenol and an olefinic compound.
Mechanisms of the isomerization processes of molecular and anionic diethylstilbestrol (DES) has been reported. Estrogen activity ofcis- andtrans-diethylstilbestrol has been evaluated. Diethylstilbestrol is a carcinogenic synthetic estrogen.Basic Info-
