Xanthones protects lead-induced chronic kidney disease (CKD) via activating Nrf-2 and modulating NF-kB, MAPK pathway.

Xanthones from a tropical fruit of Garcinia mangostana L. is known to possess a wide spectrum of pharmacologic properties, including antioxidant, anti-bacterial, anti-inflammatory, and antidiabetic activities. The current study aimed to assess the possible protective effects of xanthones against lead acetate (PbAc)-induced chronic kidney disease (CKD). To accomplish, in vitro antioxidant assays of xanthones, in vivo oxidative stress parameters, histopathology, inflammatory parameters were evaluated using PbAc-induced IRC male mice. The study was supported by in silico molecular docking of respective organ receptor protein-ligand interaction. Results revealed that xanthones potentially scavenged the DPPH, superoxide, hydroxyl, and nitric oxide radicals. Oxidative stress, kidney dysfunction, inflammatory markers, and kidney apoptosis increased by PbAc were attenuated with the co-treatment of xanthones. The treatment remarkably improved the tissue architecture. Of note, in silico prediction of activity study showed that protective role of xanthones could be due to its efficacy to activate the Nrf-2, regulate the intracellular [Ca(2+)], as well as downregulate the NF-kB, MAPK pathway. In a nutshell, xanthones could be a potential candidate for the management of PbAc-induced kidney damage.
