estriol

Estriol (Oestriol) 是G 蛋白偶联雌激素受体拮抗剂，能够作用于雌激素受体阴性乳腺癌细胞。

Estriol 17-sulfate 是一种有用的有机化合物，可用于生命科学领域的相关研究，其产品编号为 T124856。

Estriol 3,17-dihexanoate 是一种有用的有机化合物，可用于生命科学领域的相关研究，其产品编号为 T126484。

Estriol 3-β-D-glucuronide is a metabolite of estriol . It is formed from estriol by the UDP-glucuronosyltransferase (UGT) isoform UGT1A10. Estriol 3-β-D-glucuronide binds to basolateral and canalicular liver plasma membranes with Kd values of 85 and 164 μM, respectively. It competitively inhibits the hydrolysis of 4-methylumbelliferyl-β-D-glucuronide and is a substrate for hydrolysis by Klotho-human IgG1 Fc protein (KLFc).

Estriol-3-glucuronide, a natural compound found in urine, is also present in amniotic fluid during normal pregnancy [1][2].

Estriol 16α-(β-D-glucuronide) 是存在于尿中的内源代谢物，可用于研究妊娠。

Actriol (Epiestriol) 是内源性雌激素雌酮的代谢物，拥有抗炎及抗菌活性。

Mytatrienediol is a synthetic, steroidal, weak estrogen and estrogen ether derived from estriol.

The naturally-occurring estrogens are estrone , estradiol , and estriol . 16α-hydroxy Estrone (16α-OHE1) is a hydroxylated metabolite of E1 as well as an interconversion product with E2. E1 is 16α-hydroxylated by cytochrome P450 (CYP) isoforms, including CYP1A1, CYP3A5, CYP3A4, and CYP3A7, with CYP3A5 being breast-specific. 16α-OHE1 is sulphatized or glucuronidated before excretion. It is increased in rheumatoid arthritis and decreased by physical activity. Unlike the parent estrogens and other hydroxylated metabolites of E1, 16α-OHE1 binds covalently and persistently activates estrogen receptors. In addition, this metabolite increases cell proliferation and does not suppress TNF-α secretion, whereas other estrogen metabolites are not pro-proliferative and have marked effects on TNF-α secretion. The levels of 16α-OHE1 are increased in some forms of hormone therapy. Because hormone therapy increases breast cancer risk, 16α-OHE1 has been implicated as a risk factor for breast cancer, although supportive data remains elusive.
