5,7,3'-trihydroxy-3,4'-dimethoxyflavone-induced cell death in human leukemia cells is dependent on caspases and activates the MAPK pathway.[Pubmed:20175127]
Mol Carcinog. 2010 May;49(5):464-75.
Flavonoids are polyphenolic compounds which display a vast array of biological activities and are promising anticancer agents. In this study we investigated the effect of 5,7,3'-trihydroxy-3,4'-dimethoxyflavone (THDF) on viability of nine human tumor cell lines and found that it was highly cytotoxic against leukemia cells. THDF induced G(2)-M phase cell-cycle arrest and apoptosis through a caspase-dependent mechanism involving cytochrome c release, processing of multiple caspases (caspase-3, -6, -7, and -9) and cleavage of poly(ADP-ribose) polymerase. Overexpression of the protective mitochondrial proteins Bcl-2 and Bcl-x(L) conferred partial resistance to THDF-induced apoptosis. This flavonoid induced the phosphorylation of members of the mitogen-activated protein kinases (MAPKs) family and cell death was attenuated by inhibition of c-jun N-terminal kinases/stress-activated protein kinases (JNK/SAPK) and of extracellular signal-regulated kinases (ERK) 1/2. In the present study we report that THDF-induced cell death is mediated by an intrinsic dependent apoptotic event involving mitochondria and MAPKs, and through a mechanism independent of the generation of reactive oxygen species. The results suggest that THDF could be useful in the development of novel anticancer agents.
Antioxidant constituents from the stem of Sorghum bicolor.[Pubmed:12934645]
Arch Pharm Res. 2003 Jul;26(7):535-9.
The EtOAc soluble fraction from the stem of Sorghum bicolor showed a strong free radical scavenging activity. Five major compounds were isolated from this fraction. They were identified by spectral data as methyl ferulate (1), methyl p-hydroxycinnamate (2), p-hydroxybenzaldehyde (3), tricin (4), and quercetin 3,4'-dimethyl ether (5). Among these compounds, 1 exhibited a strong, free radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) with an IC50 value of 0.7 microM. We further studied the effects of these isolated compounds on the lipid peroxidation in rat liver microsomes induced by non-enzymatic method. All five compounds showed anti-lipid peroxidation activity (IC50 values of 0.5, 0.4, 0.3 and 0.3 microM, respectively).
