LY320135 has a relatively low affinity for the CB2 receptor (Ki=14.9±0.4 μM) and ten other unrelated receptors[1].
LY320135 (1 nM-10 μM) inhibits the anandamide-mediated forskolin-stimulated cAMP accumulation in CHO cell, with an IC50 of 734±122 nM[1].
LY320135 (0.1-1000 nM; 1-8 min) can reverse calcium current (ICa) inhibition by WIN 55212-2 in N18 cells, with an IC50 of 55±10 nM[1].
LY320135 (1 μM) prevents activation of Kir current by WIN 55212-2 in AtT-20-CB1 cells[1].
LY 320135 (0.001-1 μM) reduces CA1 injury induced by 20 min oxygen-glucose deprivation (OGD) in a concentration-dependent manner[2].
