Kaempferol: Unveiling its anti-inflammatory properties for therapeutic innovation

Abstract

Inflammation, driven by various stimuli such as pathogens, cellular damage, or vascular injury, plays a central role in numerous acute and chronic conditions. Current treatments are being re-evaluated, prompting interest in naturally occurring compounds like kaempferol, a flavonoid prevalent in fruits and vegetables, for their anti-inflammatory properties. This study explores the therapeutic potential of kaempferol, focusing on its ability to modulate pro-inflammatory cytokines and its broader effects on inflammatory signaling pathways. Comprehensive reviews of in vitro and in vivo studies were conducted to elucidate the mechanisms underlying its anti-inflammatory and antioxidant actions. Kaempferol effectively inhibits the production of key inflammatory mediators, including cytokines and enzymes such as COX-2 and iNOS, while also targeting oxidative stress pathways like Nrf2 activation. The compound demonstrated protective effects in various inflammatory conditions, including sepsis, neurodegenerative disorders, cardiovascular diseases, and autoimmune conditions, by modulating pathways such as NF-κB, MAPK, and STAT. Despite its promise, kaempferol's clinical application faces challenges related to its bioavailability and stability, underscoring the need for advanced formulation strategies. These findings position kaempferol as a promising candidate for anti-inflammatory therapy, with the potential to improve patient outcomes across a wide range of inflammatory diseases. Further clinical studies are required to validate its efficacy, optimize dosage, and address pharmacokinetic limitations.
