Estrogen mediates its action following binding to the estrogen receptor to form an estrogen-receptor complex. The complex initiates gene transcription and produces estrogen-induced cell and/or tissue responses, i.e., estrogenic actions[3]. Estrogen receptor(ER) consists of two subtypes i.e. ERα and ERβ, that are mostly G-protein-coupled receptors and activated by estrogen, specially 17β-estradiol. The activation is followed by translocation into the nucleus and binding with DNA to modulate activities of different genes[4].
Nafoxidine, an antiestrogen, is shown to possess antitumor activity against the Zajdela ascitic hepatoma. Nafoxidine prolonged the survival time of the rats injected with the tumor cells; complete regression of the tumor was observed when rats bearing a 3-day-old tumor were injected with this compound. Nafoxidine (Naf) also showed cytotoxic effects against the hepatoma cells in vitro. Naf competed with the binding of labelled estradiol to the tumor cells[5]. Nafoxidine and MER-25 mimicked the actions of estradiol and decreased adipose tissue lipoprotein lipase (LPL) activity by 75-80%. For adipose tissue LPL activity, both nafoxidine and MER-25 were full estrogen agonists and without antiestrogenic activity. Nafoxidine also mimicked the effects of EB by reducing food intake, body weight, and carcass adiposity in ovariectomized rats[6].
