Ound 5 potently inhibits alcohol self-administration in P-rats and binge-like Wistar rats
Ound five potently inhibits alcohol self-administration in P-rats and binge-like Wistar rats supports the concept that antagonism of k-opioid receptors may possibly be of utility for complete alcohol cessation functional activity. However, compared with naltrexone, the in vivo efficacy of compound 5 might not only be dependent on interaction with the k-opioid receptor but additionally partial agonism of the m-opioid receptor. Presumably, the profile of opioid receptor binding coupled with all the drug-like properties of compound five contributes to the optimal functional activity as an alcohol selfadministration inhibition agent in vivo. That is in agreement with current research that show that an opioid with strong k-opioid receptor antagonism, albeit possessing some opioid agonism (i.e., nalmefene) (Bart et al., 2005), was more successful at inhibition of alcohol self-administration than an opioid with broad opioid receptor antagonism (i.e., naltrexone) (Walker and Koob, 2008). Consequently, compound 5 and associated agents could represent thrilling leads for the HSPA5 Formulation following generation of opioid compounds valuable inside the therapy of alcohol abuse.AcknowledgmentsThe authors thank Drs.
