KRN5 is an oral active Nuclear factor of activated T cells 5 (NFAT5) suppressor, with an IC50 of 750 nM. KRN5 is a derivative of KRN2. KRN5 at a concentration of 1 μM inhibited the expressions of NFAT5, IL-6, MCP-1, and GM-CSF, which are NFAT5 target molecules , in RAW 264.7 macrophages stimulated with LPS.
KRN5 exhibits high oral bioavailability and metabolic stability, ameliorated experimentally induced arthritis in mice without serious adverse effects, decreasing pro-inflammatory cytokine production. Oral feeding of KRN5 every other day for 3 weeks from day 21 dose-dependently mitigated arthritis severity. When compared to methotrexate, a commonly used DMARD, the efficacy of oral KRN5 at 60 mg/kg was more potent in suppressing arthritis. The concentration of serum anti-type II collagen IgG also significantly decreased in the sera of KRN5-treated mice.
