PDGFR
PDGFR (platelet-derived growth factor receptor) is a receptor tyrosine kinase family that mediates cellular responses to platelet-derived growth factors and regulates proliferation, survival, migration, and tissue development through ligand-induced receptor dimerization and autophosphorylation mechanisms[1][2]. Mechanistically, activated PDGFR recruits multiple signaling mediators, including PI3K, PLCγ, Src-family kinases, and STAT-associated pathways, thereby coordinating cell growth, differentiation, and motility programs that are essential for normal tissue homeostasis and repair[1][2]. In developmental and physiological contexts, PDGFR signaling contributes to organogenesis, mesenchymal cell function, vascular development, and tissue regeneration, highlighting its central role in multicellular tissue organization[2][3]. In disease settings, dysregulated PDGFR activity, including constitutive receptor activation and excessive ligand-driven signaling, has been associated with malignancies, gastrointestinal stromal tumors, chronic eosinophilic leukemia, and other pathological proliferative processes[1][4]. Compared with the related isoforms, PDGFRα binds PDGF-A, PDGF-B, and PDGF-C ligands, whereas PDGFRβ preferentially binds PDGF-B and PDGF-D, resulting in overlapping but biologically distinct signaling capacities and cellular responses[1]. Furthermore, PDGFRβ displays strong chemotactic signaling activity, while PDGFRα can exert different context-dependent effects on cell migration, providing a useful framework for isoform-specific experimental design[1]. For research applications, small-molecule tyrosine kinase inhibitors targeting PDGFR signaling are widely used to investigate receptor-dependent mechanisms and disease-associated signaling networks[3].

Gomisin D
0 ImagesGomisin D is an orally active lignan that binds to PDGFRβ with a Kd 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.

Labuxtinib
0 ImagesSynonyms: EVT-8565072; THB335Labuxtinib (EVT-8565072; THB335) is a potent dual inhibitor of c-Kit and PDGFR. Labuxtinib exhibits potent inhibitory activity against wild-type c-Kit (IC50 = 0.005 μM). Labuxtinib inhibits SCF-dependent and PDGF-dependent cell proliferation, and blocks the proliferation of cells dependent on c-Kit or PDGFR signaling pathways. In animal models of skin allergy, Labuxtinib depletes skin mast cells and significantly alleviates anaphylactic shock responses. Labuxtinib can be used in research on mast cell-related diseases, respiratory diseases, inflammatory diseases, fibrotic diseases, metabolic diseases, and other related conditions.
