生物活性

AG-045572 is a GnRH receptor antagonist with Kis of 6.0 nM and 3.8 nM for human and rat GnRH receptor, respectively. AG-045572 is metabolized by CYP3A and ressuppresses testosterone[1].

体外研究
(In Vitro)

AG-045572 (10 μM,40 min,for human liver microsomes; 10 μM,10 min,for male rat liver microsomes; 1 μM,10 min,for female rat liver microsomes) 在大鼠和人体内均通过 CYP3A 代谢,在雄性和雌性人、雌性大鼠肝脏微粒体以及表达的 CYP3A4 和 CYP3A5 中的 Km 值相似 (分别为0.39、0.27、0.28、0.25和0.26 μM),而在雄性大鼠肝脏微粒体中的 Km 值为 1.5 μM,表明 AG-045572 在雄性和雌性大鼠体内通过不同的 CYP3A 同工酶代谢[1]

体内研究
(In Vivo)

AG-045572 (10 mg/kg (静脉注射) 或 20 mg/kg (口服),单剂量) 用于完整雄性大鼠,显示出中等的 T1/2、CL 和 Vss,但口服生物利用度较低,用于雌性大鼠的生物利用度较高 (24%),用于阉割雄性大鼠的药代动力学与雌性大鼠相似[1]
AG-045572 (40 mg/kg,肌肉注射,每天 2 次,共 3 天) 预处理完整雄性大鼠后,其药代动力学发生变化,各项参数与雌性和阉割雄性大鼠相似[1]

Animal Model: Male rats were surgically castrated via scrotal approach under halothane anesthesia and allowed 14 days post-operative recovery prior to study[1]
Dosage: 10 mg/kg, 20 mg/kg; 40 mg/kg
Administration: administered acutely at 10 mg/kg (i.v.) or 20 mg/kg (p.o.), one time; For multiple-dose pretreatment, male rats at 40 mg/kg, i.m. twice a day for 3 days.
Result: Showed medium T1/2, CL and Vss but oral bioavailability was low, in female rats the bioavailability was much higher (24%)
Became similar to those in female and castrated male rats.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
