Abstract

Cocaine activates sigma-1 σ(1) receptors, which function as molecular chaperones for diverse proteins including ion channels and neurotransmitter receptors. Consequently, cocaineσ-1 receptor interactions modulate multiple signaling pathways that contribute to the behavioral effects, abuse liability, and toxicity of the drug. Interventions with small-molecule antagonists of σ1 receptors represent a promising approach for the pharmacotherapy of cocaine abuse. In this chapter, we summarize recent findings regarding occupancy of σ1 receptors by cocaine and other σ1 receptor ligands, and discuss the correlation of σ1 receptor occupancy by antagonist ligands with attenuation of cocaine's motor stimulatory effects in a mouse model.
