Description

AM281 is a selective CB1 receptor antagonist with an IC50 of 9.91 nM. AM281 inhibits CB2 receptor with an IC50 of 13000 nM[1].

IC50 & Target[1]

CB1

9.91 nM (IC50)

CB2

13000 nM (IC50)

In Vitro

AM281 (0.01-10 μM) promotes a concentration dependent increase in 10 μM Aβ 25-35 induced neurotoxicity in SH-SY5Y cells in the presence of 10 μM KSO 1-6[2].

In Vivo

Acute administration (2.5, 5 and 10 mg/kg) of AM281 shortens exploration time and improves memory performance, as does chronic administration (0.62, 1.25 and 2.5 mg/kg) of AM281[3].
Chronic administration of AM281 at 2.5 mg/kg improves recognition index to the 22.1±4.8 and single dose of AM281 at 5 mg/kg improves the memory impairment to the 8.5±4, as compared with vehicle-treated which is 4.8±2.5. Administration of AM281 at a dose of 2.5 mg/kg in chronic form and 5 mg/kg in acute dose improve memory[3].

Animal Model: Male NMRI mice with the weight of 25-30 g[3]
Dosage: 0.62, 1.25 and 2.5 mg/kg (chronic administration); 2.5, 5 and 10 mg/kg (acute administration)
Administration: Administrated i.p. every day concurrently with morphine except the day of experiment (chronic administration); Singly injected 40 min before second trial (acute administration)
Result: The simultaneous daily administration of AM281 with morphine significantly shortened the exploration time, as compared with morphine-dependent mice receiving vehicle.
Acute administration at a dose of 5 mg/kg, significantly augmented recognition index.

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.
