PDGFR Ligand

Gomisin D is an orally active lignan that binds to PDGFRβ with a K_d of 10 μM. By targeting PDGFRβ to regulate signaling pathways, Gomisin D inhibits the activation and proliferation of hepatic stellate cells and promotes their apoptosis, thereby ameliorating hepatic fibrosis. Gomisin D exhibits multiple activities such as photoprotection, antimelanogenesis, antioxidant effects, and hypoglycemic activity. Gomisin D can be used in studies related to diabetes, Alzheimer's disease, and hepatic fibrosis.

pPB peptide is a cyclic peptide targeting platelet-derived growth factor receptor β (PDGFRβ). Derived from natural platelet-derived growth factor (PDGF), pPB peptide contains arginine and isoleucine as key receptor-binding residues. pPB peptide specifically binds to PDGFRβ, which is highly expressed on the surface of activated hepatic stellate cells (HSC). pPB peptide can be used in studies related to liver fibrosis, liver cirrhosis, and tumor-specific drug delivery.

PDGFR Y1021 peptide (phosphorylation) is the phosphorylated fragment of platelet-derived growth factor receptor (PDGFR). PDGFR Y1021 peptide (phosphorylation) supports association of PLCγ to PDGFR through PLCγSH2 domains, and thus promotes the production of inositol phosphates and mitogenic response.
