Introduction of 1446322-66-2 :

TAT-cyclo-CLLFVY is a cyclic peptide inhibitor of HIF-1 heterodimerization that inhibits hypoxia signaling in cancer cells. TAT-cyclo-CLLFVY disrupts HIF-1α/HIF-1β protein-protein interaction with an IC50 of 1.3 μM[1]. In Vitro: TAT-cyclo-CLLFVY inhibits HIF-1 activity in a mammalian cell luciferase reporter assay[1].
Hypoxia (1% O2) results in a ~12-fold increase in the luciferase signal, which is inhibited in a dose-dependent manner by TAT-cyclo-CLLFVY (IC50 of 19±2 μM)[1].
To assess the cell-specificity of TAT-cyclo-CLLFVY, the experiment is repeated in MCF-7 breast cancer cells with similar results (TAT-cyclo-CLLFVY IC50 of 16±1 μM)[1].
