Desription: CRMP2-Ubc9-NaV1.7 inhibitor 194 can prevent the SUMOylation of the NaV1.7-interacting protein CRMP2 and reduce NaV1.7 surface expression as well as current density. CRMP2-Ubc9-NaV1.7 inhibitor 194 showed high selectivity for NaV1.7 and reduced acute and chronic pain
in rodent models, after oral administration, without triggering adverse
events. The results suggest that targeting posttranslational mechanisms
might be an effective approach to selectively block NaV1.7 and obtain
antinociceptive effects. Vvoltage-gated sodium channel 1.7 (NaV1.7) as one of the most promising
targets for treating acute and chronic pain. However, the lack of
selectivity of current NaV1.7 channel blockers hindered the development
of effective treatments.
