Abstract

Hypoxia-inducible factor-1 (HIF-1) as a key mediator in tumor metastasis, angiogenesis, and poor patient prognosis has been recognized as an important Cancer drug target. A novel series of N-(benzofuran-5-yl)aromaticsulfonamide derivatives were synthesized and evaluated as HIF-1 inhibitor. Among these compounds, 7q exhibited specific inhibitory effects on HIF-1 by downregulating the expression of HIF-1α under hypoxic conditions. It inhibited the HIF-1 transcriptional activity (IC50=12.5±0.7μM) and secretion of VEGF (IC50=18.8μM) in MCF-7 cells. Meanwhile, it also significantly suppressed hypoxia-induced migration of HUVEC cells in nontoxic concentrations. Additionally, tube formation assay demonstrated its anti-angiogenesis activity. Finally, the in vivo study indicated that compound 7q could retard angiogenesis in CAM model. These findings supported the HIF-1 inhibitory effect and anti-angiogenic potential of this class of compounds as HIF-1 inhibitor.
