m-5049

Enpatoran is an inhibitor of TLR7(IC50 = 11.1 nM) and TLR8(IC50 = 24.1 nM). Enpatoran was found to be inactive against TLR3, TLR4, and TLR9 in vitro and in vivo.

Enpatoran (M5049) hydrochloride is a potent and orally active dual inhibitor of TLR7/8 with IC50 values of 11.1 nM and 24.1 nM in HEK293 cells, respectively. This compound specifically inhibits TLR7 and TLR8, while showing no activity against TLR3, TLR4, and TLR9. Enpatoran hydrochloride has the ability to block both synthetic molecule ligands and natural endogenous RNA ligands. Additionally, it demonstrates excellent pharmacokinetic properties in vivo. Enpatoran hydrochloride can be a valuable tool for studying and modulating both innate and adaptive autoimmunity. [1]
