The Beef Hormone Dispute is one of the most intractable agricultural controversies since the establishment of the World Trade Organization (WTO).
Zeranol, or zearanol, also known as α-zearalanol or simply zearalanol, is a synthetic nonsteroidal estrogen of the resorcylic acid lactone group related to mycoestrogens found in fungi in the Fusarium genus and is used mainly as an anabolic agent in veterinary medicine.
The molecular formula C18H26O5 may refer to:
A nonsteroidal estrogen is an estrogen with a nonsteroidal chemical structure. The most well-known example is the stilbestrol estrogen diethylstilbestrol (DES). Although nonsteroidal estrogens formerly had an important place in medicine, they have gradually fallen out of favor following the discovery of toxicities associated with high-dose DES starting in the early 1970s, and are now almost never used. On the other hand, virtually all selective estrogen receptor modulators (SERMs) are nonsteroidal, with triphenylethylenes like tamoxifen and clomifene having been derived from DES, and these drugs remain widely used in medicine for the treatment of breast cancer among other indications. In addition to pharmaceutical drugs, many xenoestrogens, including phytoestrogens, mycoestrogens, and synthetic endocrine disruptors like bisphenol A, are nonsteroidal substances with estrogenic activity.
Resorcylic acid lactones are a group of estrogenic compounds. They are lactones of resorcylic acid. Examples include the mycoestrogens zearalenone, zearalanone, zeranol (α-zearalanol), taleranol (β-zearalanol), α-zearalenol, and β-zearalenol.
Taleranol, or teranol, also known as β-zearalanol, is a synthetic, nonsteroidal estrogen of the resorcylic acid lactone group related to mycoestrogens found in Fusarium spp which was never marketed. It is the β epimer of zeranol (α-zearalanol) and is a major metabolite of zeranol but with less biological activity.
