Alpha-Mangostin in Acute Kidney Injury: Molecular Mechanisms, Regulated Cell Death, and Translational Opportunities

Information from the abstract

Acute kidney injury (AKI) is a major global health challenge associated with substantial morbidity, mortality, and progression to chronic kidney disease. Increasing evidence indicates that oxidative stress, mitochondrial dysfunction, inflammatory signaling, regulated cell death, and maladaptive tissue repair play central roles in AKI pathogenesis, yet effective disease-modifying pharmacological therapies remain unavailable. This narrative review critically evaluated current evidence regarding the pharmacological characteristics, molecular mechanisms, and translational potential of alpha-mangostin (AM), the principal prenylated xanthone isolated from the pericarp of Garcinia mangostana L., through a comprehensive synthesis of experimental and mechanistic studies. Available preclinical evidence consistently demonstrates that AM improves renal function and attenuates histopathological injury, particularly in cisplatin-induced nephrotoxicity and glycerol-induced rhabdomyolysis models. These renoprotective effects are primarily associated with suppression of oxidative stress, activation of the Nrf2/HO-1 antioxidant pathway, inhibition of NF-κB-mediated inflammatory signaling, preservation of mitochondrial function, and attenuation of apoptosis. Several emerging pathways may also contribute to AM-mediated renoprotective effects; however, current evidence remains indirect, and their roles require validation in kidney-specific models. Clinical translation remains limited by poor oral bioavailability, insufficient pharmacokinetic data, lack of standardized formulations, and the absence of human clinical trials. Overall, current evidence suggests that AM has preliminary renoprotective potential in experimental AKI models. However, the limited number of available studies, predominance of cisplatin-induced nephrotoxicity models, insufficient pharmacokinetic and safety data, and absence of human clinical studies preclude conclusions regarding its clinical efficacy or translational readiness. Further validation in diverse and clinically relevant AKI models is required before clinical investigation can be considered.
