| In vitro | PD-L1/Nampt-IN-1 (Compound T8) (0.5-5 μM) inhibits the interaction between PD-1 and PD-L1 in a dose-dependent manner, achieving an inhibition rate of 76.3% at a concentration of 5 μM. |
| In vivo | PD-L1/Nampt-IN-1 (Compound T8) administered orally at 50 mg/kg for 14 days significantly enhances tumor growth inhibition in the B16-F10 murine tumor model, attributed to the activation of the tumor immune microenvironment. In tumors, the compound accumulates at 1133.6 ng/mL at 8 hours and crosses the blood-brain barrier with 81.86 ng/mL at 1 hour. |
