The present invention provides compounds that can modulate the amount of Nav 1.7 protein, a key protein in pain signaling, that is present in the cellular surface and methods for using such compounds. In particular, compounds of the invention modulate the amount of Nav 1.7 protein on the cellular surface by modulating SUMOylation of CRMP2. Thus, compounds of the invention can be used to treat various clinical conditions associated with the presence and/or activation of Nav 1.7 protein on the cellular surface and/or SUMOylation of CRMP2.
