Comparison of the activity of isolate and commercially available ursolic acid (UA). The upper diagram shows a comparison of the isolated vs. the commercial product on the basis of inhibition of VCAM-1 expression. To confirm specificity an isotype control was included in the experiments. Mean values of a representative experiment performed in quadruplicate ± S.D. are shown. Positive control: parthenolide 10 μM, VCAM-1 expression OD 405 nm: 0.114 ± 0.008. The lower diagram shows an analysis of cytotoxicity/cell viability by the XTT assay. Data represent mean values of a representative experiment performed in triplicate ± S.D. Cells were exposed to the compounds for 24 h (compounds were added 30 min prior to TNFα addition).
