cyclo(CLLFVY) is an inhibitor for hypoxia inducible factor-1 (HIF-1), with IC50 values of 19 μM (in U2OS) and 16 μM (in MCF-7). It binds to the PAS-B domain of HIF-1α, thereby inhibiting HIF-1 dimerization and transcriptional activity. This compound also downregulates the expression of hypoxia response genes, such as VEGF and CAIX, demonstrating antitumor properties against HIF-1 associated cancers.
