4′-Hydroxywogonin

4′-Hydroxywogonin (8-Methoxyapigenin), a flavonoid, could be isolated from a variety of plants including Scutellaria barbata and Verbena littoralis. 4′-Hydroxywogonin has anti-inflammatory activity via TAK1/IKK/NF-κB, MAPKs and PI3/AKT signaling pathways. 4′-Hydroxywogonin inhibits angiogenesis by disrupting PI3K/AKT signaling. 4′-Hydroxywogonin inhibits cell proliferation and induces apoptosis^[1][2][3]. 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].
In Vivo:4′-Hydroxywogonin (10 and 20 mg/kg; i.p.; male C57BL/6 mice) alleviates LPS-induced acute lung injury (ALI) in a mouse model^[1].
