生物活性
Estrone is an estrogenic hormone secreted by the ovary as well as adipose tissue.Estrone is one of several natural estrogens, which also include estriol and estradiol.Estrone is the least abundant of the three hormones,estradiol is present almost always in the reproductive female body, and estriol is abundant primarily during pregnancy.Estrone is relevant to health and disease states because of its conversion to estrone sulfate, a long-lived derivative.Estrone sulfate acts as a reservoir that can be converted as needed to the more active estradiol.Estrone is known to be a carcinogen for human females as well as cause breast tenderness or pain, nausea, headache, hypertension, and leg cramps.In men, estrone has been known to cause anorexia, nausea, vomiting, and erectile dysfunction.It is the predominant estrogen in postmenopausal women.

重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
