Pentilludin is a novel, potent (690 nM) irreversible inhibitor of actions of the receptor type protein tyrosine phosphatase D (PTPRD). Pentilludin displays no in vitro activities in Ames or micronucleus tests, at hERG channels or at targets for currently-licensed drugs. Rats treated with pentilludin doses up to 100 mg/kg/day for two weeks have not been found to display behavioral, hematologic or serum chemistry abnormalities. Treatment with 20 mg/kg sc pentilludin prior to every other M-W-F self-administration session substantially reduces self-administration of amphetamine and more modestly reduces self-administration of remifentanil. Pentilludin provides a novel means for reducing self-administration of psychostimulant and, modestly, opiate drugs in ways that could enhance abstinence in humans.
