HIF-1 is regarded as a promising target for the drugs used in cancer chemotherapy, and creating readily accessible templates for the development of synthetic drug candidates that could inhibit HIF-1 transcriptional activity is an important pursuit. In this study, indeno[2,1-c]pyrazolones were designed as readily available synthetic inhibitors of HIF-1 transcriptional activity. Nine compounds were synthesized in 4–5 steps from commercially available starting materials. In evaluations of the ability to inhibit the hypoxia-induced transcriptional activity of HIF-1, compound 3c showed a higher level compared with that of known inhibitor, YC-1. The compound 3c suppressed HIF-1α protein accumulation without affecting the levels of HIF-1α mRNA.
