Enpatoran
Based on 18 publication(s) in Google Scholar
Enpatoran (M5049) is a potent, orally active and dual TLR7/8 inhibitor with IC50s of 11.1 nM and 24.1 nM in HEK293 cells, respectively. Enpatoran is inactive against TLR3, TLR4 and TLR9. Enpatoran can block molecule synthetic ligands and natural endogenous RNA ligands. Enpatoran exhibits excellent pharmacokinetic properties in vivo. Enpatoran can be used for both innate and adaptive autoimmunity blocking research .

? Enpatoran (M5049) exhibits high oral bioavailability (mouse 100%, rat 87%, dog 84%) following oral administration (mouse, rat and dog 1.0 mg/kg)[1].
? Enpatoran exhibits moderate half-lives (mouse 1.4, rat 5.0 and dog 13 h) due to high plasma clearance (1.4, 1.2 and 0.59 L/h/kg, respectively) combined with large volumes of distribution (2.7, 8.7 and 5.7 L/kg, respectively) following intravenous administration (mouse, rat and dog 1.0 mg/kg)[1].
