| In vitro | In the mouse podocyte cell line, APX-115 free base (5?μM; 60?min) almost completely suppresses high glucose-induced proinflammatory and profibrotic molecule expression. In the kidney, APX-115 free base attenuates Nox gene upregulation and protein expression while improving inflammatory and fibrotic processes [2]. |
| In vivo | APX-115 free base treatment decreases the urinary excretion of albumin and plasma creatinine levels. APX-115 (oral gavage; 60?mg/kg/day; for 12 weeks) significantly improves insulin resistance in diabetic mice. |
