Medchemexpress LLC D18 | 2230218-36-5 | 98.8% | C21H28N6 | 1 MG

D18 is an immune modulator and acts as a TLR7/8 dual agonist. It increases PD-L1 expression through epigenetic regulation, sensitizing tumors to PD-1/PD-L1 blockade. This substance is also an ADC cytotoxin used for the synthesis of ADC HE-S2 (HY-144497) and exhibits strong immune activation and anti-tumor activity, commonly used in cancer research.
