Furanodienone is one of the major bioactive constituents derived from Rhizoma Curcumae. Furanodienone induced apoptosis[1].
Furanodienone (0-573.8 μM; 24 hours) exhibits IC50 values : 56.4 μM (RKO), 73.7 μM (sw480), 251.1 μM (HT-29), 412.5 μM (sw620) and 573.8 μM (LoVo) at 24 hours, while that in 48 h are 51.8 μM (RKO), 44.18 μM (sw480), 168.9 μM (HT-29), 314.2 μM (sw620) and 502.1 μM (LoVo), respectively[1].Furanodienone (0-150 μM; 24 hours) induces apoptosis and shows increase in caspase-9 and -3 activity has been observed in both cells, whereas a relative minor effect on that of caspase-8 in RKO and HT-29 cells[1].Furanodienone (0-150 μM; 24 hours) increases the apoptotic rates from 2.34±0.45% to 19.45±2.37% and 27.34±0.79%, in RKO cells at 75 and 150 μM. whereas 12.4±1.08 and 20.64±3.02% apoptosis at the concentration of 75 and 150 μM are observed in HT-29 cells compared with 2.89±0.26%[1].
