The hypoxia-inducible factor-1 (HIF-1) transcription factor regulates cellular oxygen homeostasis. Agents that activate HIF-1 and downstream HIF targets represent potential drug leads for the prevention and/or treatment of ischemic disorders. In a search for small-molecule HIF-1 activators, 1936 marine invertebrate and algal extract samples (U.S. National Cancer Institute’s Open Repository) were evaluated for HIF-1 activation activity in a cell-based reporter assay. Bioassay-guided fractionation of two active extracts of the sponge Dactylospongia elegans afforded four new sesquiterpene quinones (2–5), one new sesquiterpene phenol (6), the known Golgi disruptor ilimaquinone (1), and three previously reported ilimaquinone analogues (7–9). While antiproliferative activity was observed at higher concentrations, the sesquiterpene quinones (1–3) possessing a 2-hydroxy-5-methoxy-1,4-benzoquinone moiety activated HIF-1 and increased the expression of HIF-1 target gene vascular endothelial growth factor (VEGF) in T47D cells.
