Wedelolactone is a coumestan that has gained attention in the field of research for its diverse biological activities. It is frequently used as a tool to study signaling pathways due to its ability to inhibit 5-lipoxygenase and the IKK complex, which are involved in the synthesis of leukotrienes and the activation of NF-κB, respectively. By modulating these pathways, wedelolactone is instrumental in dissecting the cellular responses to inflammatory stimuli and the regulation of genes involved in inflammation and immunity. Additionally, its role as a potent inhibitor of the DNA damage response kinase DNA-PK has made it valuable in the study of cellular responses to DNA damage and repair mechanisms. Researchers also employ wedelolactone to explore its potential effects on estrogen receptors, contributing to the understanding of hormone-mediated signaling.
