The assay mentioned in the prompt is called PUBCHEM_BIOASSAY, which stands for High Throughput Screening (HTS) Image-Based Screen for Selective Antagonists of the KOR Receptor. This assay belongs to the confirmatory class, which means that it is designed to validate and confirm the results of previous assays. The depositor of the assay has also defined several related pubchem assays, such as AID1777, AID1778, AID1785, and AID2284, which are linked to the main assay. The assay is classified as a Direct single protein target assigned, which indicates that it targets only one specific protein. The assay organism is Homo sapiens, and its type description is Functional, which means that it measures the biological activity of the KOR receptor. Overall, this information provides a clear understanding of the PUBCHEM_BIOASSAY and its properties. Does this molecule show efficacy in this assay?
