Summary
epi-Aszonalenin A is a fungal indole alkaloid that inhibits inflammation and angiogenesis.
Details
epi-Aszonalenin A is a prenylated indole alkaloid isolated from Aspergillus species. It suppresses ox-LDL-induced inflammation, angiogenesis, and apoptosis in HUVEC cells by downregulating LOX-1 expression and inhibiting NF-κB, PI3K/AKT, and MAPK signaling pathways. These properties suggest potential applications in atherosclerosis and vascular inflammation research.
