PD-L1/Nampt-IN-1

PD-L1/Nampt-IN-1 is an orally active inhibitor that targets both PD-L1 and NAMPT (nicotinamide phosphoribosyltransferase), with IC50 values of 63 nM and 582 nM, respectively. It exhibits cross-species affinity, with KD values of 52.6 nM for hPD-L1 and 49.1 nM for mPD-L1. This compound effectively suppresses tumor growth by activating the tumor immune microenvironment and is applicable in melanoma research.
