Abstract
Hedgehog proteins, signaling molecules implicated in human embryo development and cancer, can be inhibited at the stage of autoprocessing by the trivalent arsenical phenyl arsine oxide (PhAs(III) ). The interaction (apparent Ki , 4 × 10(-7) M) is characterized by an optical binding assay and by NMR spectroscopy. PhAs(III) appears to be the first validated inhibitor of hedgehog autoprocessing, which is unique to hedgehog proteins and essential for biological activity.Entities:
