MMP9 and ovarian adenocarcinoma: Biological tests conducted for complexes 1–4 against the A2780 human ovarian adenocarcinoma cell lines, involved the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, the FGF-2 (Soluble basic Fibroblast Growth Factor production), the MMP-9 (Matrix metalloproteinase-9), and the intracellular nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB).
