アブストラクト A series of substituted ortho-carboranylphenoxyacetanilides were synthesized and evaluated for their ability to inhibit hypoxia-induced HIF-1 transcriptional activity using a cell-based reporter assay in HeLa cells expressing the HRE-dependent firefly luciferase reporter construct (HRE-Luc) and constitutively expressing CMV-driven Renilla luciferase reporter, and their ability to inhibit cell growth (GI50) using the MTT assay. Among the compounds synthesized, 1g and 1l showed significant inhibition of hypoxia-induced HIF-1 transcriptional activity (IC50: 1.9 ± 0.4 and 1.4 ± 0.2 μM, respectively). Both compounds suppressed HIF-1α accumulation in a concentration-dependent manner. The porcine heart malate dehydrogenase (MDH) refolding assay revealed that compound 1l inhibited human Hsp60 chaperone activity (IC50: 6.80 ± 0.25 μM) and this inhibition activity was higher than that of ETB (IC50: 10.9 ± 0.63 μM).
