Biological Activity
| Description | Mestranol is the 3-methyl ether of ethinyl estradiol, which is a potent estrogen receptor agonist and used as oral contraceptives. | |
|---|---|---|
| Targets |
|
|
| In vitro | Mestranol is extensively metabolized to hydroxylated products whose bio- logical activity is less well characterized. [1] | |
| In vivo | Mestranol (0.2 mg/kg) results in an increased percentage of liver occupied by AHF expressing glutathione S-transferase (PGST) in rats. Mestranol administration increases the focal hepatocyte labeling index compared with the control with a trend at the lower dose and a significant difference at the higher dose. Mestranol (0.02 mg/kg and 0.2 mg/kg diet) results in a decrease in the non-focal labeling index compared with that observed for the corresponding concentration of Mestranol alone. Mestranol significantly increases the non-focal hepatic labeling index in uninitiated rats compared with that observed in rats administered the basal diet only. [1] Mestranol (50 mg/100 g b.wt.) has a significant reduction in the apparent number of alpha-2-adrenoceptors in the frontal cortex and nucleus tractus solitarius (NTS) of rat, while apparent numbers of both alpha-1 and alpha-2-adrenoceptors are depressed in the locus coeruleus.
