The multifactorial consequences of menopausal estrogen deficiency affect numerous tissues throughout the body. Supplemental hormonal therapies carry the burden of a risk/benefit ratio that must be highly individualized. Selective estrogen receptor modulators (SERMs) are estrogen receptor (ER) agonist/antagonists designed to induce benefits comparable with estrogen while minimizing adverse effects. Here, we review the estrogen agonist/antagonist profile of ospemifene, a novel triphenylethylene derivative recently approved to treat dyspareunia, a symptom of vulvar and vaginal atrophy (VVA) due to menopause, both preclinically and clin. Ospemifene binds ERα and ERβ with approx. equal affinities. In preclin. models, ospemifene increased vaginal and uterine epithelial thickness and mucification to the same extent as estrogen. Ospemifene did not induce endometrial hyperplasia in animal models; there also was no stimulatory effect on endometrial cells. In rat and human mammary cells in vitro, ospemifene evokes a dose-dependent inhibition on estrogen-induced cell responses and cell proliferation, supporting an antiestrogenic effect in breast. In contrast, ospemifene has an estrogenic effect on bone, as seen by improved bone mineral d., strength, mass, and histomorphometry in preclin. models, consistent with improvements in markers of bone resorption and formation in postmenopausal women. Based on the preclin. evidence, ospemifene has beneficial estrogen-like effects on the vaginal epithelium, preliminary evidence to support a neutral endometrial profile, antiproliferative effects in breast, and estrogenic effects in bone. Taken together, especially regarding estrogen-like effects on the vaginal epithelium, ospemifene presents a profile of tissue-specific effects that appear novel among available SERMs and well-suited for the treatment of VVA. In the experiment, the researchers used many compounds, for example, (Z)-2-(4-(4-Chloro-1,2-diphenylbut-1-en-1-yl)phenoxy)ethan-1-ol (cas: 128607-22-7Product Details of 128607-22-7).
(Z)-2-(4-(4-Chloro-1,2-diphenylbut-1-en-1-yl)phenoxy)ethan-1-ol (cas: 128607-22-7) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Product Details of 128607-22-7
