Relationships between the structural characteristic of curcumins that affect cell proliferation of hepatocarcinoma cells

Relationships between the structural characteristic of curcumin and dimethoxycurcumin and their antitumoral activity were studied. Treatment of HepG2 cells for 24 h with the curcumin and dimethoxycurcumin resulted in apoptosis induction and dose-dependent inhibition of cell proliferation. The calculated docking and the DFT method, suggest a structure-activity relationship between the activities of dimethoxycurcumin and curcumin structure and the apoptosis in HepG2 cells
