Common NameArzoxifene
DescriptionArzoxifene belongs to the class of organic compounds known as diarylethers. These are organic compounds containing the dialkyl ether functional group, with the formula ROR', where R and R' are aryl groups. Based on these results, Lilly announced they are discontinuing further development of the drug and would not seek regulatory approval. Arzoxifene is a very strong basic compound (based on its pKa). Arzoxifene is devoid of the uterotrophic effects of tamoxifen, suggesting that, in contrast to tamoxifen, it is unlikely that the clinical use of arzoxifene will increase the risk of developing endometrial carcinoma. Arzoxifene is a highly effective agent for prevention of mammary cancer induced in the rat by the carcinogen nitrosomethylurea and is significantly more potent than raloxifene in this regard. However arzoxifene failed to meet secondary endpoints of reduction in non-vertebral fractures and cardiovascular events and improvements in cognitive function. Arzoxifene (INN; developmental code name LY-353381) is a selective estrogen receptor modulator (SERM) of the benzothiophene group which was never marketed. It has antiestrogenic effects in the breast, mixed estrogenic and antiestrogenic effects in the uterus, and estrogenic effects in bone. A 2015 network meta-analysis found that arzoxifene significantly reduced the risk of breast cancer (RR 0.415) and to a greater extent than raloxifene (RR 0.572) or tamoxifen (RR 0.708). The medication has been found to suppress gonadotropin levels in postmenopausal women, increase sex hormone-binding globulin levels, and decrease insulin-like growth factor 1 and insulin-like growth factor-binding protein 3 levels. This compound has been identified in human blood as reported by (PMID: 31557052 ). Arzoxifene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Arzoxifene 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.
