Biological Activity

Description 6-Iodopravadoline (AM630) is a selective cannabinoid CB2 receptor antagonist with Ki of 31.2 nM.
Targets
CB2 receptor [1]
(Cell-free assay)
31.2 nM(Ki)
In vitro

AM630 behaves as a low-potency neutral competitive antagonist in AM630-pre-incubated cells, a low-potency agonist in SR144528-pre-incubated cells, and a much higher-potency inverse agonist/antagonist in vehicle-pre-incubated cells. AM630 is a protean ligand that can target a constitutively active form of the hCB2 receptor with low affinity to produce agonism or neutral antagonism and a constitutively inactive form of this receptor with much higher affinity to produce inverse agonism.[2]
In vivo

Chronic AM630 treatment is anxiolytic in light-dark box (LDB) and elevated plus maze (EPM) tests. Chronic AM630 treatment increases gene and reduces protein expression of CB2 receptors, GABAAα2 and GABAAγ2 in cortex and amygdala. In addition, chronic AM630 administration decreases the anxiety of DBA/2 mice in the LDB test. The efficacy of AM630 in reducing the anxiety of the spontaneously anxious DBA/2 strain of mice strengthens the potential of the CB2 receptor as a new target in the treatment of anxiety-related disorders.[1]

(Cell-free assay)
31.2 nM(Ki)
In vitro AM630 is a CB2 cannabinoid receptor ligand with Ki of 31.2 nM and a CB2 /CB1 affinity ratio of 165. AM630 inhibits [35 S]-GTPγS binding to CB2 receptor membranes (EC50=76.6 nM), enhances forskolin-stimulated cyclic AMP production in CB2-transfected cells (5.2 fold by 1 μM ), and antagonizes the inhibition of forskolin-stimulated cyclic AMP production in this cell line induced by CP55940. AM630 (10 μM) inhibits forskolin-stimulated cyclic AMP production In CB1-transfected cells by 45.9%. [1] AM630 behaves as a competitive antagonist of △9-THC, CP 55,940, WIN 55212-2, anandamide and (R)-(+)-arachidonyl-l’-hydroxy-2’-propylamide (AM356) in mouse isolated vas deferens with Kd of 14.0, 17.3, 36.5, 278.8, and 85.9 nM, respectively. [2] AM630 ( 10 μM) activates a robust Ca2+ accumulation in a subset (35- 40%) of TG neurons, and with EC50 of 15.6 μM. AM630 are able to generate currents in TG sensory neurons with the activation threshold of 1 μM. AM630 responses are mediated by the TRPA1 channel in a majority of TG small-to-medium sensory neurons, which is modulated by TRPV1. Pre-treatment with AM630 (25 μM) is able to inhibits the Capsaicin (CAP) effects, mustard oil (MO) and WIN 55,212-2 (WIN) TRPA1 mediated responses. [3] AM630 (100 nM) effectively inhibits osteoclastogenesis in culture with RANKL in the presence and absence of Ti particles, as reducing the number of tartrate-resistant acid phosphatase-positive cells by more than 50%. AM630 (100 nM) inhibits mRNA expression of RANK and cathepsin K in RAW cells stimulated by Ti particles and RANKL. AM630 (100 nM) reduces protein expression of interleukin-1β and tumor necrosis factor-α in RAW cells cultured with Ti particles. AM630 has no toxic effect on RAW cells. [4]
In vivo AM630 (30 μg) injection are not able to induce nociceptive behaviors or thermal hyperalgesia in hind paw of WT mice, but significantly attenuate CAP-induced thermal hyperalgesia. AM630 (30 μg) is able to reverse WIN inhibition CAP-induced thermal hyperalgesia. AM630 exerts its peripheral effects by not only inhibiting CB1 and CB2, but also activating TRPA1 channels and subsequently desensitizing TRPA1 as well as TRPV1 channels. [3]
