<p dir="ltr">Previous research shows that the prevalence rates for alcohol use disorder, opioid use disorder, and chronic pain are high worldwide. Additional work has demonstrated that the most used pain medications are potentially addictive and not suitable for chronic use. Recent research suggests that inhibiting adenylyl cyclase type 1 (AC1) may be an alternative, non-addictive, method for reducing pain. The purpose of this study was to explore the effects of a novel AC1 inhibitor (CMPD84) on pain threshold and alcohol reward-related behavior in high-alcohol preferring male and female mice (HAP). No research to date has investigated the effects of AC1 inhibition on pain threshold and alcohol-induced conditioned place preference (CPP) in HAP mice, making this the first study to do so. Two manual von Frey experiments were run to explore the effects of CMPD84 (compared to alcohol and morphine) on pain threshold. Three CPP experiments were run to assess the effects of CMPD84 on the expression and acquisition of alcohol-induced CPP. Brain samples were taken from the NAc shell and vlPAG to assess levels of PKCε after the pain threshold experiments and the acquisition CPP experiment. PKCε has previously been shown to be linked to alcohol reward-behavior and pain relief. Results show that CMPD84 was more efficacious in increasing pain threshold in HAP mice compared to morphine and alcohol. CMPD84 also reduced the acquisition and expression of alcohol-induced CPP. AC1 inhibition reduced levels of PKCε in the brain, which matched behavioral results that reduced the expression and acquisition of alcohol-induced CPP, as well as increased pain threshold. These results suggest that PKCε may be linked to AC1 inhibition, pain threshold, and alcohol reward-related behaviors. </p>
