Insoluble in water and dilute inorganic acid, slightly soluble in benzene and chloroform, soluble in methanol, ethanol, acetone, vegetable oil and alkali solution, soluble in ether. Low toxicity, LD50 (mouse, oral) 1000 mg/kg. |
| Use | Used as a hormone drug |
| In vitro study | Hexestrol binds to ERα and ERβ with EC50 of 0.07 nM and 0.175 nM, respectively. Hexestrol inhibits AKR1B13 activity with an IC50 of 3.2 μm. Hexestrol inhibits the activity of d-galactose dehydrogenase in Streptococcus thermophilus 1-dehydrogenase with an IC50 of 0.063 mM. Hexestrol inhibited the dehydrogenase activity of AKR1C20 with an IC50 value of 2.7 μm for 10 μm 4-androstene-3α-o1-17-one. Hexestrol inhibits 17HSD5 with an IC50 of 30 μm and inhibits TBER1 with an IC50 of 0.8 μm. Hexestrol reacts with DNA through catechol quinone and is therefore a carcinogen. |
| In vivo study | Hexestrol(6 mg/kg, I. p.) administration may reduce ovulation in mice showing smaller ovaries and reduced corpus luteum with oocytes. |
