6-O-Methacrylate, a trilobolide, is isolated from the leaves of Wedelia trilobata. 6-O-Methacrylate displays marked antimalarial activity, with IC₅₀ of 8.9 μg/mL against P. falciparum parasite. 6-O-Methacrylate also has anti-tobacco mosaic virus (TMV) activity^{[1] [2]} .

6-O-Methacrylate (10 μg/mL) shows anti-TMV activities in the pretreated tobacco plants with inhibition rate of 59.6%^[2] .

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
