Description

A cell-permeable, readily bioavailable 2-picolinamide derivative that acts as a highly potent antagonist of transient receptor potential cation channel subfamily M member 8 (TRPM8, IC50 = 10.9 nM in icilin evoked Ca2+ currents in HEK293 cells stably expressing human TRPM8). At much higher levels it is shown to activate human TRPA1 (EC50 = 2.8 µ,M) and inhibit human TRPV1 (IC50 = 3.0 µ,M). Selectively reduces behavioral and neural responses to cooling in spinal ligated rats (~ 30 mg/kg), but not in naï,ve rats., A cell-permeable, readily bioavailable 2-picolinamide derivative that acts as a highly potent antagonist of transient receptor potential cation channel subfamily M member 8 (TRPM8, IC50 = 10.9 nM in icilin evoked Ca2+ currents in HEK293 cells stably expressing human TRPM8).
