Candidone is a type of flavanone phenolic compound with anti-cancer and antibacterial activities. Candidone inhibits the proliferation of hepatoblastoma and cholangiocarcinoma cells and induces their apoptosis by up-regulating p21, Bax, and caspase 3/9, and down-regulating Bcl-2 and survivin. It reduces the metastatic ability of cancer cells by inhibiting the expression of phosphorylated p38 and matrix metalloproteinase MMP-9. Candidone has inhibitory effects on multidrug-resistant bacterial strains. Candidone binds to the base pairs of DNA in a groove-binding manner, thereby slightly altering the conformation of DNA[1][2][3].
