Loxoribine Chemical Properties,Usage,Production
Description
Loxoribine is a guanosine derivative and an agonist of toll-like receptor 7 (TLR7). It is selective for TLR7 over other human TLRs in a cell-based reporter assay at 1 mM.. Loxoribine induces proliferation, increases the antibody response to sheep red blood cells, and activates natural killer cell activity against Yac-1 lymphoma cells in murine splenocyte cultures (EC50s = 10-50, 3-20, and 13-22 μM, respectively). Loxoribine (250 μM) increases production of IL-12, IL-23, IL-27, and IL-10 by human monocyte-derived dendritic cells (MoDCs). Loxoribine-treated MoDCs induce higher levels of IL-17 and IFN-γ secretion by co-cultured allogeneic CD4+ T cells compared to control MoDCs. Loxoribine (120 mg/kg) reduces the number of pulmonary metastases in the B16 mouse model of melanoma, an effect enhanced by co-administration of IL-2, and exhibits adjuvant activity in mice immunized with a B16 tumor vaccine.
