Fadrozole is a non-steroidal aromatase inhibitor (IC50s = 5 and 1.4 nM for human placental and rat ovarian microsomal aromatase, respectively). It selectively inhibits estrogen over progesterone production induced by luteinizing hormone (LH) in hamster ovarian tissue as well as corticosterone and aldosterone production induced by adrenocorticotropic hormone in rat adrenal tissue (IC50s = 0.03, 160, 100, and 1 μM, respectively). It also decreases ovarian estrogen levels in rats when administered at a dose of 0.26 mg/kg. Fadrozole inhibits conversion of cholesterol to 27-hydroxycholesterol by the cytochrome P450 (CYP) isomer 27A1 (Ki = 4.6 μM). It inhibits growth of androstenedione-stimulated mammary D2 cells implanted into thoracic mammary fat pads of mice by 95% when administered at a dose of 0.5 mg per animal per day.

Animal experiment: | Rats: Rats are treated with daily dosing with Fadrozole hydrochloride in purified water by gavage for 2 years. There are 60 rats in each of four groups given 0, 0.05, 0.25 or 1.25 mg/kg daily. Control rats receive only water. Clinical signs are recorded weekly and the animals are examined for palpable masses every 4 weeks for the first 9 months, then every 2 weeks for the remainder of the study[2]. Mice: Fadrozole hydrochloride is administered in the form of sub-dermal long-term release pellets (20 mg/wt kg, in three-week-release pellets), starting 1 week prior to the infection, using a 10-gauge needle. Three pellets are administrated during the study. Placebo pellets are administered to another group of infected mice, in the same fashion as the inhibitor. After 1 week, mice are infected and killed 8 weeks later[3]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
