SMU-3k is a STING activator and PD-L1 inhibitor, with a PD-L1 IC50 of 106 nM, a KD of 386 nM for human PD-L1, and a KD of 352 nM for murine PD-L1. SMU-3k activates the STING pathway, induces phosphorylation of TBK1 and IRF3, and promotes the expression of IFN-beta, IL-6 and CXCL10. SMU-3k blocks the PD-1/PD-L1 interaction, reduces PD-L1 levels and induces PD-L1 internalization. Through dual immunomodulation, SMU-3k exerts synergistic tumor growth inhibitory effects in a mouse colon cancer model. SMU-3k can be used for the research of colon cancer[1].
