体内研究
(In Vivo)

FR194921 (32 mg/kg; p.o.) 在大鼠中具有良好的口服生物利用度,AUC 为 6.91 µg·h/mL,Cmax 为 2.13 µg/mL,Tmax 为 0.63 h,BA 为 60.6%[1].
FR194921 (0.032、0.1、0.32 mg/kg;口服) 剂量依赖性地减弱 CPA (HY-103181) 诱导的低运动[2]
FR194921 (0.1-10 mg/kg;腹腔注射) 显着改善东莨菪碱 (HY-N0296) 诱导的记忆缺陷[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: SD rats[2]
Dosage: 0.032, 0.1, 0.32 mg/kg
Administration: P.o.; administered orally 25 min prior to intraperitoneal administration of CPA (0.056 mg/kg; i.p.)
Result: Dose-dependently attenuated the hypolocomotion induced by CPA with an ED50 value of 0.08 mg/kg and statistical significance at 0.32 mg/kg.
Animal Model: SD rats[2]
Dosage: 0.1, 0.32, 1, 3.2, 10 mg/kg
Administration: I.p.; Scopolamine (HY-N0296)(1 mg/kg, i.p.)
Result: Significant cognitive enhanced following scopolamine-induced memory deficits in 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.
