1-[4-(N-Benzylamino)phenyl]-3-phenylurea derivatives as a new class of hypoxia-inducible factor-1alpha inhibitors.
A series of 1-[4-(N-benzylamino)phenyl]-3-phenylurea derivatives 2a-r were synthesized as HIF-1alpha inhibitors. Among the compounds synthesized, compound 2k was found to be a potent inhibitor against HIF-1alpha accumulation under hypoxic condition and inhibited the hypoxia-induced HIF-1 transcriptional activity in HEK293 cells (IC(50)=7.2 microM). Furthermore, compound 2k suppressed the hypoxia-induced secretion of VEGF in HeLa cells (IC(50)=15 microM).
