In Vitro

4′-Hydroxywogonin (8-Methoxyapigenin; 0.5-15 μM; 0-24 h) has low cytotoxicity and inhibits NO and PGE2 production in LPS-stimulated RAW 264.7 macrophages by suppression of iNOS and COX-2 expression[1].
4′-Hydroxywogonin (0.5-15 μM; 1 and 12 h) suppresses LPS-induced expression of pro-inflammatory cytokines in RAW 264.7 macrophages and suppresses LPS-induced activation of NF-κB[1].
4′-Hydroxywogonin (0.5-15 μM; 1 h) suppresses LPS-induced degradation of IκB-α and activation of IKK and TAK and suppresses the phosphorylation of MAPK and AKTin in RAW 264.7 macrophages[1].
4′-Hydroxywogonin (0.5-15 μM; 24 h) inhibits ROS production in LPS-stimulated RAW 264.7 macrophages[1].
4′-Hydroxywogonin (0-10 μg/mL; 24 h) reduces the viability of SW620 cells in a concentration- and time-dependent manner and decreases the mRNA and protein expression of vascular endothelial growth factor-A (VEGF-A), the predominant pro-angiogenic cytokine in tumor angiogenesis[2].
4′-Hydroxywogonin (24 h; SUP-B15 and Jurkat cells) induces apoptosis and decreases the expression of C-MYC, BCL-2 and cleaved caspase 3[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
