Biochem/physiol Actions

Estradiol (known as alpha Estradiol or 17 alpha Estradiol) is a biologically active estrogen in human breast cancer cells in tissue culture.17-estradiol and its selective receptor, ER-X, are not part of a classical hormone/receptor endocrine system but of a system with important autocrine/paracrine functions in the developing and adult brain. 17-Estradiol may have enormous implications for hormone replacement strategies at the menopause and in the treatment of such neurodegenerative disorders as Alzheimer′s disease and ischemic stroke.

In modified Tyrode's solution, 17 beta-estradiol at concentrations between 0.1 microgram/ml and 320 nmoles/ml was effective in increasing human spermatozoal forward migration. 17 alpha-Estradiol, although structurally similar to 17 beta-estradiol, had no effect on human spermatozoal motility.

17beta-Hydroxysteroid dehydrogenase type 7 (17beta-HSD7) catalyzes the reduction of estrone (E(1)) into estradiol (E(2)) and of dihydrotestosterone (DHT) into 5alpha-androstane-3beta,17beta-diol (3beta-diol), therefore modulating the level of mitogenic estrogens and androgens in humans. By classical and parallel chemistry, we generated several
