request a copy of the Item No. Product Name Summary Endocrinology catalog A nonsteroidal estrogen produced from the metabolism of the isoflavonoid phytoestrogen daidzein by human intestinal 13184 (±)-Equol microflora (EC50 = 200 and 74 nM for human ERα and ERβ, respectively)
A weaker ER agonist that binds to ERα and ERβ with Ki values of 27.4 and 15.4 nM, respectively; demonstrates higher ER 10010172 (R)-Equol agonist activity at ERα compared to ERβ (EC50 = 66 and 330 nM, respectively) Estrogen receptor agonist activity of this naturally occurring enantiomer (EC = 85 and 65 nM for human ERα and ERβ, 10010173 (S)-Equol 50 respectively) is similar to that of genistein but exceeds that of daidzein 2,3-bis
10008842 (4-Hydroxyphenyl) An ERβ selective agonist (EC50 = 0.85 nM) Propionitrile
Selectively inhibits AKR1C1 (Ki = 4 nM) over AKR1C2 (Ki = 87 nM), AKR1C3 (K = 4.2 μM), and AKR1C4 (K = 18.2 μM); 3-bromo-5-phenyl i i 13574 potently inhibits the metabolism of progesterone by bovine Salicylic Acid aortic endothelial cells overexpressing AKR1C1 (IC50 = 460 nM) 5-bromo-3-pheny Selectively inhibits AKR1C1 (K = 140 nM) over AKR1C2 (K = 1.97 13379 i i Salicylic Acid µM) and AKR1C3 (Ki = 21 µM) A major metabolite produced from testosterone by the actions 6β-hydroxy Testosterone 10008519 of CYP3A4 and CYP3A5, accounting for 75-80% of all (DEA Schedule III) metabolites formed from testosterone 11α-hydroxy 10008647 Testosterone (DEA A CYP3A metabolite of testosterone Schedule III)
