Catalog No.	Product Name	Information	Selective / Pan	IC50 / Ki
S9730	CU-CPT9a	CU-CPT9a is a potent and specific antagonist of Toll-like receptor 8 (TLR8) with IC50 of 0.5 nM.	Selective	TLR8, IC50: 0.5 nM
S4461	CU-CPT-8m	CU-CPT-8m (CPD1578) is a specific antagonist of toll-like receptor 8(TLR8) with IC50 of 67 nM and Kd of 220 nM.	Selective	TLR8, IC50: 67 nM; TLR8, Ki: 220 nM
S7161	Motolimod (VTX-2337)	Motolimod (VTX-2337) is a selective and potent Toll-like receptor 8 (TLR8) agonist with EC50 of 100 nM, > 50-fold selectivity over TLR7. Phase 2.	Selective	TLR8, EC50: 100 nM
S9937	CU-CPD107	CU-CPD107 is a selective, dual-activity small-molecule which demonstrated differential activity against the TLR8 agonists and ssRNA ligands. In the presence of R848, CU-CPD107 acts as a TLR8 signaling inhibitor (IC50=13.7 μM). In the presence of ssRNA, CU-CPD107 shows synergistic agonist activities, while CU-CPD107 alone is unable to influence TLR8 signaling.	Selective	TLR8, IC50: 13.7 μM
S9931	Enpatoran Hydrochloride	Enpatoran (M5049) hydrochloride is a potent, orally active, and dual TLR7/8 inhibitor with IC50s of 11.1 nM and 24.1 nM, respectively, in HEK293 cells.	Pan	TLR8, IC50: 24.1 nM
S9623	Telratolimod	Telratolimod (3M-052, MEDI9197) is an agonist of toll-like receptor 7 (TLR-7) and toll-like receptor 8 (TLR-8) with antitumor activity.	Pan
S8133	Resiquimod (R-848)	Resiquimod (R-848, S28463) is an immune response modifier that acts as a potent TLR 7/TLR 8 agonist that induces the upregulation of cytokines such as TNF-α, IL-6 and IFN-α. Resiquimod reduces hepatitis C virus (HCV) infection. Phase 2.	Pan
S4157	Chloroquine diphosphate	Chloroquine diphosphate is a 4-aminoquinoline anti-malarial and anti-rheumatoid agent, also acting as an ATM activator. Chloroquine is also an inhibitor of toll-like receptors (TLRs).	Pan
