SIRT1 Activator 1 (Compound 3), a marine-derived xyloallenoide A derivative from the Xylaria sp. mangrove fungus, exhibits angiogenic effects in zebrafish and protects human endothelial progenitor cells (hEPCs) from AngII-induced senescence. It achieves this by elevating SIRT1 expression and modulating the AMPK/Akt signaling pathway [1].
