Design, synthesis and insight into the structure–activity relationship of 1,3-disubstituted indazoles as novel HIF-1 inhibitors

Design, synthesis and insight into the structure–activity relationship (SAR) of 1,3-disubstituted indazoles as novel HIF-1 inhibitors are described. In particular, the substituted furan moiety on indazole skeleton as well as its substitution pattern turns out crucial for the high HIF-1 inhibition.
