Licoflavone A
Based on 3 publication(s) in Google Scholar
Licoflavone A is an orally active PTP1B/VEGFR-2 inhibitor, with an IC50 of 54.5 μM against PTP1B, an IC50 of 14.36 μM and a Kd of 142.38 nM against human VEGFR-2. Licoflavone A blocks the PI3K/AKT and MEK/ERK signaling pathways. Licoflavone A induces G1 phase cell cycle arrest, apoptosis via the intrinsic mitochondrial pathway (apoptosis), and inhibits migration, invasion and epithelial-mesenchymal transition (EMT) of gastric cancer cells. Licoflavone A inhibits the proliferation of gastric cancer cells in vitro and in xenograft models. Licoflavone A reduces the expression levels of HIF-1α, GLUT1, LDHA, PKM2 and HK2 in hypoxic gastric cancer cells, decreases glucose uptake and suppresses glycolysis. Licoflavone A can be used in research related to gastric cancer, type 2 diabetes and obesity.
