Fig. 3 Cell growth, assayed using MTT test, of normal human buccal fibroblast cells (BFC) untreated and treated with jasmonic acid derivatives 1-3 for 72 hrs. Stock solution of the compounds was prepared in DMSO and the final concentration of this solvent was kept constant at 0.25%. Control cultures received DMSO alone. Each value represents the mean ± SD of three experiments, performed in quadruplicate.
