APX-115, also known as EWHA-18278, is a potent, orally active pan NADPH oxidase (Nox) inhibitor. APX-115 protects development of diabetic nephropathy in podocyte specific NOX5 transgenic mice. APX-115 might be a promising therapeutic agent for the treatment of DN because of its pan-NOX inhibitory activity, including its NOX5 inhibitory activity, and also owing to its anti-inflammatory effect.

How to use

In Vitro:

APX-115 free base (5 μM; 60 min) almost completely suppresses high glucose-induced proinflammatory and profibrotic molecule expression in the mouse podocyte cell line. In the kidney, APX-115 free base attenuates Nox gene upregulation and protein expression while improving inflammatory and fibrotic processes.

In Vivo:

APX-115 free base (oral gavage; 60 mg/kg/day; for 12 weeks) significantly improves insulin resistance in diabetic mice. APX-115 free base treatment decreases the urinary excretion of albumin and plasma creatinine levels.
