ML-154

ML-154 (NCGC-84) is a drug which acts as a selective, non-peptide antagonist at the neuropeptide S receptor NPSR.[1] In animal studies it decreases self-administration of alcohol in addicted rats, and lowers motivation for alcohol rewards, suggesting a potential application for NPS antagonists in the treatment of alcoholism.[2]
