KRN5 是 KRN2 的衍生物,是具有口服活性的T 细胞激活核因子 (NFAT5)的抑制剂,IC50值为 750 nM。KRN5 有潜力用于 NFAT5-介导的慢性关节炎的研究。
生物活性 | KRN5, a derivative of KRN2, is an oral activeNuclear factor of activated T cells5 (NFAT5)suppressor, with anIC50of 750 nM. KRN5 has potential to treat NFAT5-mediated Chronic Arthritis[1]. |
IC50& Target | |
体外研究 (In Vitro) | KRN5 is less toxic than BBR as determined by a cytotoxicity assay, hERG K+ channel assay, cytochrome inhibition assay, and liver microsomal metabolic stability test, which makes it a potential drug candidate[1]. KRN5 at a concentration of 1 μM inhibits the expressions of NFAT5, IL-6,MCP-1, and GM-CSF,which are NFAT5 target molecules, in RAW264.7 macrophages stimulated with LPS[1].

体内研究 (In Vivo) | Oral feeding of KRN5 (15 mg/kg and 60 mg/kg) every other day for 3 weeks from day 21 dose-dependently mitigates arthritis severity[1]. The concentration of serum anti-type II collagen IgG also significantly decreases in the sera of KRN5-treated mice. TNF-α and IL-6 production by LPS-stimulated splenocytes are significantly lower in KRN5-treated CIA mice than in vehicle-treated mice[1].
Animal Model: | 8-week-old DBA/1Jmice immunized with bovine type II collagen[1]. | Dosage: | 15 mg/kg and 60 mg/kg. | Administration: | Orally on alternate days (every other day) for 3 weeks. | Result: | Dose-dependently mitigated arthritis severity. |
