A hepatocyte-targeting near-infrared ratiometric fluorescent probe for monitoring peroxynitrite during drug-induced hepatotoxicity and its remediation

Abstract

A novel hepatocyte-targeting near-infrared fluorescent probe named Gal-NIR is developed. Gal-NIR shows ratiometric response to ONOO⁻ with high sensitivity and selectivity. Moreover, the probe can accurately target the hepatocyte, and thus is used for assessing drug-induced hepatotoxicity and its remediation by using hepatoprotective medicines in living cells and mice.
