TM 38837 is a highly potent cannabinoid 1 receptor (CB1) inverse agonist (IC50 values are 8.5 nM and 605 nM for inhibition of [3H]-CP 55940 binding at CB1 and CB2 receptors, respectively). Displays 71-fold selectivity for CB1 receptors over CB2 receptors. Inhibits GTP binding to CB1-overexpressing cell membranes in vitro (EC50 = 18.5 nM). Peripherally restricted. Promotes fear behaviors when given by intracerebrovascular (icv) injection in mice.
TM 38837 is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.
