CL097, a potent TLR7/8 agonist, induces pro-inflammatory cytokines in macrophages [1]. CL097 induces NADPH oxidase priming, resulting in an increase in the fMLF-stimulated ROS production. Highly water-soluble derivative of the imidazoquinoline compound R848 (Resiquimod)

CL097 induces activation of NF-κB at 0.1 μM in TLR7-transfected HEK293 cells and at 4 μM in TLR8-transfected HEK293 cells [1].
CL097 induces hyperactivation of the NADPH oxidase by stimulating the phosphorylation of p47phox on selective sites in human neutrophils and suggests that p38 MAPK, ERK1/2, protein kinase C, and Pin1 control this process. CL097 induces the phosphorylation of p47phox on specific sites and enhances fMLF-induced p47phox phosphorylation [2].

CL097 and CD40 agonist stimulation induce efficient diabetogenic Cytotoxic T lymphocyte (CTL) function in NOD mice. CL097 (5 mg/kg, s.c.) alone causes modest specific lysis of the target peptide (∼25%). However, treatment with a combination of CL097 and CD40 agonist (10 mg/kg, i.p.) results in an increase of approximately twofold in the specific lysis of the IGRP-peptide-coated targets compared with CL097 treatment alone [3].

Toll-like receptor 7 (TLR7) is an innate immune receptor for single-stranded RNA (ssRNA) and has an important role in infectious diseases. We previously reported that TLR7 shows synergistic activation in response to two ligands, guanosine, and ssRNA. However, the specific ssRNA
