Hepatoprotective effect of diammonium glycyrrhizinate and neuroprotective effect of piperazine ferulate on AmB-induced liver and kidney injury by suppressing apoptosis in vitro and in vivo.

Amphotericin B (AmB) induced liver and kidney injury is often responsible for hepatic and renal dysfunction. Therefore, the protection strategy on liver and renal functions in patients treated with AmB should be emphasized. In this paper, diammonium glycyrrhizinate (DG) and piperazine ferulate (PF) were taken as the research object to study its hepatoprotective and neuroprotective effect on AmB-induced liver and kidney damage in vitro and in vivo. The microplate method and ELISA kits were employed for the biochemical detection in the serum and urine of mice. Flow cytometric analysis and western blotting analysis were conducted to study the mechanism of DG and PF. Our results confirmed the prevention capacity of DG and PF on AmB-induced liver and kidney injury through the alleviation of pathological changes and enzyme reducing action. Furthermore, DG and PF suppressed ROS-mediated mitochondrial apoptosis in AmB-treated mice and cells through Caspase pathway and Caspase-independent AIF pathway. In summary, DG and PF could protect AmB-induced hepatotoxicity and nephrotoxicity by disrupting oxidative stress and apoptosis.
