Application

LY255582 may be used in opioid receptor-mediated cell signaling studies.

Biochem/physiol Actions

LY255582 is a centrally active opioid receptor antagonist (defined as an inverse agonist in 2011 JPET paper) that inhibited weight gain in obese Zucker rats over 30 days. It is more that 5-fold selective for mu opioid receptor compared to kappa opioid receptors and 13-fold selective over delta opioid receptors.

LY255582 inhibits the diet-associated increases in mesolimbic dopamine levels and reduces the consumption of highly-palatable food intake.
