描述 | AM630 (iodopravadoline), a novel aminoalkylindole. AM630 behaved as a competitive antagonist of CP 55,940, WIN 55,212-2, anandamide and (R)-(+)-arachidonyl-1'-hydroxy-2'-propylamide (AM356), producing rightward shifts in the log concentration response curves of these cannabinoid receptor agonists. AM630 was markedly more potent as an antagonist of delta 9-THC and CP 55,940 (Kd = 14.0 and 17.3 nM respectively) than as an antagonist of WIN 55,212-2, AM356 or anandamide (Kd = 36.5, 85.9 and 278.8 nM respectively)[3]. AM630 is a protean ligand that can target a constitutively active form of the hCB(2) receptor (R*) with low affinity to produce agonism or neutral antagonism and a constitutively inactive form of this receptor (R) with much higher affinity to produce inverse agonism, and that the constitutive activity of whole cells is decreased less by pre-incubation with AM630 than with the higher-efficacy inverse agonist, SR144528[4]. AM251 and AM630 activated trigeminal (TG) sensory neurons in a concentration-dependent fashion (threshold 1 μM). AM630 (1-100 μM), but not AM251, was a significantly more potent agonist in cells co-expressing both TRPA1 and TRPV1 channels[5]. |
