Technical Data

Formula

C22H21Cl2IN4O
Molecular Weight 555.24 CAS No. 183232-66-8
Solubility (25°C)* In vitro DMSO 40 mg/mL (72.04 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description AM251 block the inhibitory effects of endocannabinoids and synthetic cannabinoid agonists on transmitter release through an action at presynaptic cannabinoid 1 receptors in brain.
Targets
CB1 [2]
In vitro AM251 reduces veratridine-dependent (tetrodotoxin suppressible) release of L-glutamic acid and GABA from synaptosomes with IC50 of 8.5 μM and 9.2 μM, respectively. AM251 increases (by 2.3 times) the Kd of radioligand without altering Bmax. AM251 inhibits equilibrium binding by allosterically accelerating the dissociation of the [3H]-batrachotoxinin A 20-alpha-benzoate:sodium channel complex. [1] AM251 reduces cholesteryl ester synthesis in unstimulated and acetylated LDL-stimulated Raw 264.7 macrophages, CB2+/+ and CB2 −/− peritoneal macrophages. [2]
In vivo AM251 causes a sustained reduction of daily food intake in the rat. [3] AM251 produces food avoidance and behaviors associated with nausea but does not impair feeding efficiency in rats. [4] AM251 disrupts memory consolidation of the inhibitory avoidance task. [5] AM251 has caused a significative decrease in the test step-down latency when compared to the control group, but no differences are detected in the open field habituation task, including the number of crossings, i.e. there are no motor effects. [6] AM251 (4.0 mg/kg) reduces freezing during a conditioned tone cue played within a novel context. [7]
Features A selective cannabinoid 1 blocker.
