Abstract in brief
Modafinil is a mild psychostimulant with pro-cognitive and antidepressant effects that interacts with the dopamine transporter (DAT) differently than cocaine, resulting in minimal abuse potential and making it a promising treatment for cocaine addiction.
Unlike cocaine, which strongly favors an outward-facing DAT conformation, modafinil and other atypical inhibitors (like benztropine and GBR12909) do not depend on this conformation for binding; their affinity ratios remain unaffected by treatments (like zinc) that stabilize the outward-facing state, indicating a different binding mechanism.
Computational modeling suggests that cocaine and methylphenidate stabilize the outward-facing DAT conformation, whereas modafinil and similar atypical inhibitors do not, explaining their different behavioral and reinforcing profiles despite all targeting the dopamine transporter.
