Toll-like receptor 8 (TLR8) recognizes pathogen-derived single-stranded RNA fragments to trigger innate and adaptive immune responses. Chronic hepatitis B (CHB) is associated with a dysfunctional immune response, and therefore a selective TLR8 agonist may be an effective treatment option. Structure-based optimization of a dual TLR7/8 agonist led to the identification of the selective TLR8 clinical candidate (R)-2-((2-amino-7-fluoropyrido[3,2-d]pyrimidin-4-yl)amino)-2-methylhexan-1-ol (GS-9688, (R)-7). Potent TLR8 agonism (IL-12p40 EC50 = 220 nM) and >100-fold TLR7 selectivity (IFN-α EC50 > 50 μM) was observed in human peripheral blood mononuclear cells (PBMCs). The TLR8-ectodomain:(R)-7 complex confirmed TLR8 binding and a direct ligand interaction with TLR8 residue Asp545. Oral (R)-7 had good absorption and high first pass clearance in preclinical species. A reduction in viral markers was observed in HBV-infected primary human hepatocytes treated with media from PBMCs stimulated with (R)-7, supporting the clinical development of (R)-7 for the treatment of CHB.

Paragraph 0297, (2014/04/03)
[Problem] An excellent drug for treating or preventing cardiovascular diseases, based on cGMP production enhancing action due to soluble guanylate cyclase activating action, is provided. [Means for Solution] It was found that imidazopyridine compounds having a carbamoyl group at the 3-position and a substituent bonded at the 8-position via an oxygen atom in an imidazo[1,2-a]pyridine skeleton exhibits a cGMP production enhancing action by a potent soluble guanylate cyclase activating action, and is useful as a drug for treating or preventing various soluble guanylate cyclase-related cardiovascular diseases, thereby completing the present invention.
