DMBT
DMBT is an orally effective anti-tumor metastasis and anti-angiogenesis agent. DMBT downregulates key molecules such as EGFR/p-Akt/HIF-1α/VEGF/MMP-9, inhibits the HIF-1α/VE-cadherin (cadherin)/MMPs and Nrf2/HO-1 signaling pathways, and reduces hypoxia-induced ROS levels as well as the secretion and activity of MMP-9. DMBT inhibits hypoxia-induced vasculogenic mimicry, cancer cell migration, invasion and metastasis, and exhibits no obvious cytotoxicity to normal cells. DMBT reduces the area of laser-induced choroidal neovascularization lesions. DMBT can be used in studies related to breast cancer, melanoma and macular degeneration.
