KN1022 is an inhibitor of phosphorylation of platelet-derived growth factor (PDGF) receptor with IC50 of 0.26 μM.

AG 1295, a selective inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine-kinase, effectively halts PDGFR autophosphorylation without impacting the autophosphorylation of the EGF receptor[1][2][3][4].

WQ-C-401 is an orally active inhibitor of the platelet-derived growth factor receptor (PDGFR). It inhibits cell proliferation by blocking PDGFR auto-phosphorylation in a concentration-dependent manner, with EC50 values of 3.5 nM for PDGFRαY849 and 5.8 nM for PDGFRβY1021. Additionally, WQ-C-401 suppresses the proliferation and migration of PASMCs by inhibiting PDGF-BB-induced phosphorylation of ERK1 2, reduces collagen I synthesis, and increases α-SMA expression, thereby preventing pulmonary vascular remodeling. This compound shows promise for research in the field of pulmonary arterial hypertension.

2-Methyl-3-phenylquinoxaline (compound 38) serves as an effective inhibitor of the Platelet-Derived Growth Factor Receptor Tyrosine Kinase (PDGF-RTK), exhibiting significant inhibitory activity against the full-length PDGFR kinase in intact cells (IC50 greater than 100 μM).

ABT-869 is an innovative ATP-competitive inhibitor targeting all vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptor tyrosine kinases (RTKs). Its hydrophilic metabolite, A-849529, contains carboxyl and amino groups.

AG 370, an indole tyrphostin, is a potent inhibitor of PDGF-induced mitogenesis with an IC50 of 20 μM, and it shows weak inhibition of the EGF receptor.

PD-161570 is a potent and ATP-competitive human FGF-1 receptor inhibitor with an IC50 of 39.9 nM and a Ki of 42 nM. It also inhibits the PDGFR, EGFR, and c-Src tyrosine kinases with IC50 values of 310 nM, 240 nM, and 44 nM, respectively.

Vascular endothelial growth factor receptor 2 (VEGFR2, also known as KDR and FLK1) is a receptor tyrosine kinase that regulates angiogenesis, vascular development, and embryonic hematopoiesis in response to VEGF isoforms A, C, and D. VEGFR2 kinase inhibitor II is a reversible, cell-permeable inhibitor of VEGFR2's kinase activity (IC50 = 70 nM). It less potently inhibits the platelet-derived growth factor receptor β (PDGFRβ; IC50 = 920 nM) and related receptor and non-receptor tyrosine kinases. VEGFR2 kinase inhibitor II blocks the growth of human umbilical vein endothelial cells stimulated with either VEGF or PDGF (IC50s = 110 nM and 2 μM, respectively).

Ansornitinib (ANG-3070) is an orally active KDR and PDGF receptor inhibitor with antifibrotic activity that inhibits platelet-derived growth factor receptor (PDGFR) and vascular endothelial growth factor receptor (VEGFR2), and may be useful for the study of diseases caused by abnormal or excessive fibrosis.

Tyrphostin AG1296 (Tyrphostin AG 1296) is an inhibitor of PDGFR with IC50 of 0.3-0.5 μM, no activity to EGFR.

The growth factors, platelet-derived growth factor (PDGF) and basic fibroblast growth factor (bFGF) play major roles in enhanced smooth muscle cells growth in rodent blood vessels after vascular injury. Tyrosine kinase inhibition has been shown to be effective in blocking tyrosine phosphorylation at the PDGF and bFGF receptors in cultured fibroblast and vascular smooth muscle cells which in turn inhibits their proliferation[1]. CGP 53716 is a specific PDGFR tyrosine kinase inhibitor on SMC (smooth muscle cell) proliferation and migration in vitro and in neointimal formationin vivo[3]. CGP 53716 inhibited serum-induced cell growth in RASMC (rat aortic smooth muscle cells). And it completely blocked PDGF-BB tyrosine receptor autophosphorylation in RASMC and 3T3 cells, PDGF-BB-induced phosphorylation of mitogen-activated protein kinase at 1 μM in RASMC and inhibited PDGF-BB-induced c-Fos protein expression at 1 μM in RASMC; consistent with inhibition of PDGF-BB-induced DNA synthesis. Further, CGP 53716 inhibited PDGF-BB-, bFGF- and EGF-induced DNA synthesis in a concentration-dependent manner in each cell line. And it showed a 2- to 4-fold selectivity for PDGF-BB-stimulated DNA synthesis over bFGF or EGF in RASMC or 3T3 cells[1]. CGP 53716 inhibited dose dependently tyrosine phosphorylation of both the known PDGFRs: the PDGFR-α and PDGFR-β. After rat carotid artery ballooning injuryin vivo, the migration of alpha-actin-positive cells on the luminal side of internal elastic lamina was decreased with 50 mg kg day of CGP 53716 from 38 ± 10 (control group) to 4 ± 2. Intima media ratio was inhibited by 40% after 14 days in the CGP 53716-treated group (P=0.028) after rat aortic denudation[3].
