Common Name | Nafoxidine |

Description | Nafoxidine belongs to the class of organic compounds known as phenylnaphthalenes. Phenylnaphthalenes are compounds containing a phenylnaphthalene skeleton, which consists of a naphthalene bound to a phenyl group. It was developed at around the same time as tamoxifen and clomifene, which are also triphenylethylene derivatives. Nafoxidine is a very strong basic compound (based on its pKa). However, it produced side effects including ichthyosis, partial hair loss, and phototoxicity of the skin in almost all patients, and this resulted in the discontinuation of its development. Nafoxidine was assessed in clinical trials in the treatment of breast cancer and was found to be effective. The drug was originally synthesized by the fertility control program at Upjohn as a postcoital contraceptive, but was subsequently repurposed for the treatment of breast cancer. Nafoxidine (INN; developmental code names U-11,000A, NSC-70735) or nafoxidine hydrochloride (USAN) is a nonsteroidal selective estrogen receptor modulator (SERM) or partial antiestrogen of the triphenylethylene group that was developed for the treatment of advanced breast cancer by Upjohn in the 1970s but was never marketed. Nafoxidine is a long-acting estrogen receptor ligand, with a nuclear retention in the range of 24 to 48 hours or more. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nafoxidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nafoxidine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
