Syringic Acid Alleviates Doxorubicin-Induced Hepatotoxicity Through PI3K/Akt-Mediated Nrf-2/HO-1 Signaling Pathways in Male Rats.

Syringic acid (SYA) is a significant phenolic compound with the potential for various biomedical uses, including uses of its hepatoprotective properties. Doxorubicin (DOX) is a drug used in the treatment of several tumors, but its side effects, particularly hepatotoxicity, limit its effectiveness. This study investigated the therapeutic effects of SYA on DOX-induced hepatic injury in rats. Molecular docking studies were performed using AutoDock Vina. Five groups of Sprague-Dawley rats (eight in each group) were studied. Gp1 was a negative control group; Gps2-5 was administered intraperitoneally (i.p.) with DOX at a dosage of 4 mg/kg once a week for a month; and Gp2 was left as a positive control group. Gps3-5 received oral SYA at doses of 25, 50, or 75 mg/kg/day, respectively, for a month. Histopathological, molecular, and biochemical analyses were conducted one month after the last SYA dosages were given. The findings demonstrated that by reversing biochemical changes and reducing oxidative stress and inflammation, SYA therapy considerably reduced DOX-induced hepatotoxicity in rats. These results implied that SYA may lessen the hepatotoxicity that DOX causes in rats.
