Norethindrone (炔诺酮) 是合成的孕酮,能模拟内源卵巢激素的功能。A synthetic progestin
Information
Norethindrone (Norethisterone) is a synthetic progestin, which mimic the actions of the endogenous ovarian hormone progesterone.
In vitro
Norethisterone, or, is a 19-nortestosterone derivative, that lacks a C19 methyl group and possesses C17 ethinyl substitution, and primarily displays progestational activity rather than androgenic activity and, to a lesser extent, has oestrogenic and anti-oestrogenic activity. NET shows five- to eight-fold weaker progesterone receptor binding and transactivation activities than the Org 2058 (100%) and two-fold stronger than progesterone. Binding and transactivation activities of NET for androgen receptor (5α-dihydrotestosterone 100%) are 3.2 and 1.1%, respectively, for estrogen receptor none (estradiol 100%) and for glucocorticoid receptor below 1% (dexamethasone 100%). Norethisterone (1 nM) inhibits serum-stimulated or oestradiol (0.1 nM)-induced proliferation of MCF-7 by 41% and 34%, respectively. Norethisterone (50 nM) induces significant effects on rat osteoblast proliferation, differentiation, and mineralization processes, mimicking the effects of estradiol, which is mediated by estrogen receptor.
In vivo
Norethisterone displays hormonal properties in vivo. Mean active dose (MAD) of Norethisterone s.c. in progestagenic test (McPhail), androgenic test (Hershberger), estrogenic test (Allen–Doisy), and in a progestagenic and estrogenic test (ovulation inhibition test) is 0.63 mg/kg, 2.5 mg/kg, 4 mg/kg, and 0.235 mg/kg, respectively, and the MAD for orally administration is 0.25 mg/kg, 20 mg/kg, 8 mg/kg, and 12 mg/kg, respectively. Norethisterone influences bone formation and resorption. Norethisterone (80 μg/day) decreased bone resorption in SO and OVX mice, while enhances estradiol-stimulated endosteal bone formation. Norethisterone at the dose which is used in hormonal therapy for prevention of osteoporosis has a slight protective effect against bone mineral loss in castrated mice.
