HuR inhibitor KH-3

HuR inhibitor KH-3 is a small molecule, selective inhibitior of HuR function with Ki of 0.83 and 0.72 uM in FP and AlphaLISA assays, respectively.KH-3 potently inhibits breast cancer cell growth in vitro and in vivo.KH-3 inhibits breast cancer cell invasion in vitro as well as delays initiation of lung colonies and improves mouse survival in an experimental metastasis model in vivo.KH-3 suppresses breast cancer cell invasion by disrupting HuR-FOXQ1 mRNA interaction.Inhibition of HuR with KH-3 yielded a significant reduced in the progression of pathological cardiac hypertrophy in a transverse aortic constriction model.
