In Vivo

GW-405833 (3, 10 and 30 mg/kg; i.p.) reverses hyperalgesia in both pain models in a dose-dependent manner in WT mice, while this effect is preserves in CB1KO mice but absent in CB2KO mice[1].
GW-405833 (30 mg/kg; i.p.) does not induce cataplexy, motor ataxia, hypothermia, or acute tail-flick antiesthesia in CD1KO mice[1].

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

Animal Model: CB1KO mice, CB2KO mice, WT mice[1]
Dosage: 3, 10 and 30 mg/kg
Administration: Intraperitoneal injection (i.p.)
Result: Increased the paw withdrawal threshold in CB2KO and WT mice in a dose-dependent manner.
Restored mechanical paw withdrawal thresholds relative to baseline in CB2KO and WT mice at doses as low as 10 mg/kg.
Retained antiallodynic effects in CB2KO mice.
Produced a dose-dependent increase in mechanical threshold in WT mice, but this antiallodynic effect was absent in CB1KO mice.
Blocked the antihyperalgesic effect by the CB1 antagonist rimonabant (HY-14136), but not by the CB2 antagonist SR144528 (HY-13439).

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.
