  • Immune response modifier. Potent antitumor and antiviral compound [1, 3, 10, 11, 13, -16].
  • Stimulates antibody secretion and cytokine production [2].
  • Used as adjuvant to increase the effectiveness of vaccines [2, 7, 9, 10].
  • Potent and selective synthetic ligand for Toll-like receptor 7 (TLR7) in mouse and for TLR7 and TLR8 in human [4-6].
  • Activates immune cells via the TLR7/TLR8 MyD88-dependent signaling pathway and leads to the induction of NF-κB [4].
  • NLRP3/NALP3 inflammasome activator, independent of TLRs and RIG-I [8].
  • Upregulator of the opioid growth factor receptor [12].
  • Used in the treatment of skin lesions such as herpes simplex virus [16].
