生物活性
Abiraterone Acetate (CB 7630) is a highly active and selective 17α-hydroxylase/17,20 lyase (CYP17A1) inhibitor with an IC50 of 72 nM. Abiraterone Acetate (CB 7630) inhibitor CYP11B1, CYP11B2 and CYP3A4 with IC50 of 1.6, 1.8 and 2.7 μM. Abiraterone Acetate (CB 7630) is used in the study of castration-resistant prostate cancer. Abiraterone Acetate (CB 7630) blocks the formation of testosterone by inhibiting CYP17A1. Abiraterone Acetate (CB 7630) caused significant reductions in the weights of the ventral prostate and seminal vesicles. There was no reduction seen in the weight of these organs with KC. Abiraterone Acetate (CB 7630) reduced plasma testosterone to 0.1 nM or less, despite a three- to four-fold increase in the plasma level of luteinizing hormone (LH).

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。
