TLR7/8 agonist 13
TLR7/8 agonist 13 is an orally active dual agonist of TLR7 (lowest effective concentrations (LEC) [hTLR7] = 1.6 μM) and TLR8 (LEC [hTLR8] = 1.6 μM). TLR7/8 agonist 13 exhibits agonistic activity against human peripheral blood mononuclear cells (hPBMCs) (LEC [hPBMC] = 0.5 μM). TLR7/8 agonist 13 induces endogenous IFNα, activating myeloid dendritic cells and monocytes toward a TH1 phenotype in mice and cynomolgus monkeys. TLR7/8 agonist 13 reduces viral load and HBV surface antigen expression in a mouse model of chronic AAV-HBV infection. TLR7/8 agonist 13 has the potential to indirectly induce IFNγ, which may promote HBV antigen-specific CD8 T cell-mediated responses. TLR7/8 agonist 13 can be used to study hepatitis B virus.

TLR7/8 agonist 13 (Compound 50 d) induces IFNα, IFNγ, IL-12p40, IL-12p70, and TNF-α production in PBMCs[1].

TLR7/8 agonist 13 (5 mg/kg, p.o., once a week, 8 weeks) inhibits HBsAg secretion and HBV viral load by two distinct noncytotoxic mechanisms in AAV-HBV C57Bl/6 mice model[1].
TLR7/8 agonist 13 (3-30 mg/kg, p.o., once) induces endogenous IFNα, an interferon stimulated gene response, but also activation of myeloid dendritic cells and monocytes toward a TH1 phenotype in cynomolgus monkeys model[1].

-
Dosage:3, 9, and 30 mg/kg
-
Administration:p.o., once
-
Result:Had no change of clinical observations and body weight, body temperature, clinical pathology.
Induced IFNα production from the 9 mg/kg dose, induced an ISG response and CXCL10 from a lower dose than IFNα, i.e., 3 mg/kg.
Up-regulated Isg15 and Mx1, activated monocytes, IL-15 from 9 mg/kg, activated Myeloid dendritic cells, MCP1, MIP-1β, and IL-1Ra from 3 to 9 mg/kg, activated TNFα and IL-6 from 30 mg/kg.
