pdgf-receptor

PDGFR Tyrosine Kinase Inhibitor III (PDGF Receptor Tyrosine Kinase Inhibitor III) (PDGF Receptor Tyrosine Kinase Inhibitor III) is a multikinase inhibitor that inhibits PDGFR, EGFR, FGFR, PKA, and PKC, respectively. PDGFR Tyrosine Kinase Inhibitor III can be used for the research of amyotrophic lateral sclerosis [1].

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

CYM50260 is a potent and exquisitely selective agonist of sphingosine-1-phosphate 4 receptor (S1P4-R, EC50= nM) with no activity against S1P1-R, S1P2-R, S1P3-R and S1P5-R.

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. PD-161570 also inhibits the PDGFR, EGFR and c-Src tyrosine kinases with IC50 values of 310 nM, 240 nM, and 44 nM, respectively.

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].

AG-494 (Tyrphostin B48) is an inhibitor of epidermal growth factor receptor kinase.

AG 370, an indole tyrphostin, functions as a powerful inhibitor of PDGF-induced mitogenesis, demonstrating an IC50 of 20 μM. Additionally, it exhibits weak inhibition capabilities towards the EGF receptor.

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].

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

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).

SU 5402 is a potent multi-targeted receptor tyrosine kinase inhibitor with IC50 of 20 nM, 30 nM, and 510 nM for VEGFR2, FGFR1, and PDGF-Rβ, 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.
