Neurology
Cell culture and mouse studies identified a TRPM8 antagonist that could help treat pain. Chemical synthesis of dibenzyl tryptamine analogs and HEK cell-based ion channel assays yielded a compound that inhibited TRPM8 with an IC50 value of 0.2 nM. In a mouse model of chemical-induced pain, the compound decreased cold hypersensitivity compared with vehicle. In a mouse model of chemotherapy-induced neuropathic pain, subcutaneous injection of the compound decreased cold allodynia compared with no treatment. Next steps could include testing the compound in additional models of pain.
