TLR7/8 Agonist - Thiazoquinoline compound

CL075 (3M002) is a thiazoloquinolone derivative that stimulates TLR8 in human peripheral blood mononuclear cells.

It activates NF-κB and triggers preferentially the production of TNF-α and IL-12 [1].

CL075 seems also to induce the secretion of IFN-α through TLR7 but to a lesser extend.

It induces the activation of NF-κB at 0.4 µM (0.1 µg/ml) in TLR8-transfected HEK293 cells, and ~ 10 times more CL075 is required to activate NF-κB in TLR7-transfected HEK293 cells.
