Murrangatin may be a valuable anti-tumor-promoting agent, it can significantly inhibit Epstein-Barr virus early antigen (EBV-EA) activation, and preserve the high viability of Raji cells, it also exhibits cytotoxicity against cholangiocarcinoma cell line, KKU-100. Murrangatin exhibits antibacterial activity against P. gingivalis (ATCC 33277). Murrangatin also shows soluble epoxide hydrolase inhibitory activity with IC50 values 13.9±6.5uM. Murrangatin and murracarpin may be a new backbone for developing inhibitors of cyclooxygenase 2, they show chondroprotective activity by downregulation of interleukin-1β, tumor necrosis factorα, prostaglandins E2,and matrix metalloproteinases -13, and both of them may be a new backbone for developing inhibitors of cyclooxygenase 2.
