    Scientific background

    Chembridge-5861528 (CHEM), a derivative of HC-030031 compound, is a potent and selective TRPA1 (TRP ankyrin 1) channel antagonist. TRPA1 channels play an important role in models of inflammatory and neuropathic pain and have the ability to detect pungent or irritant compounds.

    Administration of Chembridge-5861528 attenuates diabetic hypersensitivity. It reduces hypersensitivity by suppressing the TRPA1 channel-mediated facilitation of transmitter release from central terminals of primary afferent nerve fibers1,2.

    Blocking TRPA1 channels may help in migraine attack and can be used as a possible target for its treatment.

    Evidence in several studies shows that TRPA1 antagonists could serve as novel therapeutic strategies for the treatment of chemotherapeutic-induced peripheral neuropathy2.
