IWP-3 is a potent inhibitor for porcupine which is known to catalyze the palmitoylation of Wnt proteins which are crucial in tumorigenesis. | [Biological Activity]
iwp-3 is an inhibitor of wnt production.wnt signaling proteins, a group of small secreted proteins, are active in tissue homeostasis, embryonic development, as well as tumorigenesis. wnt proteins can bind to the cell surface receptors, initiating a signaling cascade that results in the β-catenin activation of gene transcription. | [Biochem/physiol Actions]
IWP-3 is a Wnt inhibitor that prevents palmitylation of Wnt proteins by Porcupine (Porcn). IWP-3 is an inactivator of Porcn function that acts as inhibitors of Wnt production. Studies revealed that IWP-3 induces differentiation of human mesoderm cells to form cardiomyocytes. | [in vitro]
in previous study, iwp-3 was identified as an inhibitor of wnt production that could regulate in vitro wnt pathway activity with an ic50 value of 40 nm. in addition, iwp-3 was found to be able to inactivate porcupine, a o-acyltransferase for palmitoylating wnt proteins that was critical for the signaling ability and secretion. moreover, iwp-3 at 5 μm was found to block wnt-dependent phosphorylation of the low-density lipoprotein receptor-related protein 6 and the scaffold protein dishevelled, resulting in preventing the accumulation of β-catenin [1]. in another study, iwp-3 was applied to promote cardiomyocyte generation from human embryonic stem cells by inhibiting wnt signaling [2]. | [IC 50]
