RQ 00203078
Biological Activity
Potent TRPM8 antagonist (IC50 values are 5.3 and 8.3 nM for rat and human channels respectively). Exhibits >350-fold selectivity for TRPM8 over TRPV4, TRPV1 and TRPA1. Reduces HSC3 and HSC4 oral squamous carcinoma cell migration and invasion in vitro. Also attenuates icilin-induced wet dog shakes in rats. Orally active.

Pain Poster
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
