OBJECTIVE
Ritonavir (RIT) is a human immune deficiency virus (HIV) protease inhibitor (PI) active against HIV-1 and HIV-2. Among various adverse effects of PIs, hepatotoxicity is a very common adverse reaction of RIT which is concentration dependent. Red clover isoflavones are found to possess anti-inflammatory, antioxidant and anti-apoptosis activity. Furthermore, recent studies have demonstrated that these isoflavones can be used to alleviate the side-effects of drugs. Hence, the present study was inquested to ascertain the effect of Formononetin (FMN) and Biochanin A (BCA) on RIT induced hepatotoxicity.
METHODS
Five groups of animals were subjected to treatment as control, toxic control (RIT), third group (RIT + FMN), fourth group (RIT + BCA), the fifth group (RIT + FMN + BCA) and sixth group (FMN + BCA) for 14 days. The animals were evaluated for estimation of liver toxicity markers, inflammatory biomarkers, in-vivo biochemical antioxidant parameters. The liver tissues were further evaluated histopathologically and western blotting examination for localization of apoptotic gene expression that plays a pivotal role in hepatotoxicity.
RESULTS
FMN and BCA ameliorated the increased levels of biochemical markers of liver, attenuated the RIT induced Bax, caspase-3, NFκB and eNOS activation and persuaded the Bcl2 and pAkt level. Alteration in the levels of inflammatory markers was also observed in both hepatic tissue and serum.
CONCLUSIONS
FMN and BCA exerts hepatoprotective effect through modulating the oxidative stress, inflammation, apoptosis and reversing the tissue degeneration suggesting its therapeutic role in hepatotoxicity and other hepatocellular diseases.
