  • Guanosine analog derivatized at position N7 and C8 [1].
  • Very potent immunostimulatory compound that increases cytokine production [2-5].
  • Antitumor and antiviral activity compound [5, 6, 7, 12].
  • Potent and selective synthetic ligand for Toll-like receptor 7 (TLR7) [7-10].
  • Co-incubation with thymidine homopolymer oligodeoxynucleotides (ODN) redirected the stimulatory effect of loxoribine away from TLR7 toward TLR8 [11].
  • Induces autophagy and autophagy-induced cell death in Caco-2 cells [12].
  • Shows adjuvant activity to increase the effectiveness of vaccines [4].
  • Inducer of Hunner-Type Interstitial Cystitis (HIC).
