Product Description

Estradiolbenzoate is a synthetic ester, especially 3-benzoyl ester, natural estrogen, estradiol. Estrogens guides the development of female genes during embryonic development and puberty. Estradiol is the main female hormone secreted by the ovaries before menopause. Estradiolbenzoat Chemicalbooke is an estradiol analogue that contains a benzyl ester at the C-3 position and is often used in combination with progesterone to induce estrus in livestock. The compound binds to human and mouse estrogen receptor alpha (ERα), and chicken ER, with IC50 values ranging from 22-28 nM. This reflects a 6-10 fold reduction in affinity compared to estradiol.

Function

The effects of daily injections of 5 microgram estradiol benzoate (EB) on the patterns of food and ethanol consumption were studied in ovarectomized rats given free access to food, a 10% ethanol solution, and water. EB led to an immediate, but transient, suppression of both food and ethanol intake. The time course and magnitude of these effects were virtually identical. While the decrease in total food intake was achieved by a permanent decrease in the duration of eating bouts, the decline in total ethanol consumption apparently resulted from decreased rates of licking within bouts. Gradual increases in the frequency of eating and ethanol-drinking bouts allowed total food and ethanol intake to return to baseline within three weeks of the first injection. Total water intake rose three-fold during EB administration and this was due to increases in both the duration and frequency of drinking bouts. The similarity in effects induced by EB on the patterns of food and ethanol intake were discussed in terms of ethanol's caloric property.
