PD 089828 (Synonyms: EGF/FGF/PDGF Receptor Tyrosine Kinase Inhibitor) |
| رقم الكتالوجGC44583 |
PD 089828 هو مثبط تنافسي لـ ATP لـ FGFR-1 و PDGFR-β و EGFR (IC50s \u003d 0.15 و 1.76 و 5.47 ميكرومتر ، على التوالي) ومثبط غير تنافسي لـ c-Src التيروزين كيناز (IC50 \u003d 0.18 ميكرومتر). يثبط PD 089828 أيضًا MAPK بـ IC50 من 7.1 ميكرومتر. PD 089828 يثبط PDGF- و EGF- و bFGF بوساطة مستقبلات التيروزين كيناز في المختبر. PD 089828 له نشاط خلوي طويل الأمد.

PD 089828 is a competitive inhibitor of the receptor tyrosine kinases FGFR1, PDGFRβ, and EGFR (IC50s = 0.15, 1.76, and 5.47 µM, respectively) and a noncompetitive inhibitor of the nonreceptor tyrosine kinase c-Src (IC50 = 0.18 µM). It is selective for these targets over insulin receptor tyrosine kinase, PKC, and CDK4 (IC50s = >50 µM) but does inhibit MAPK (IC50 = 7.1 µM). PD 089828 decreases PDGF-BB-, EGF-, and bFGF-induced phosphorylation of PDGFR, EGFR, and FGFR1, respectively, in a concentration-dependent manner in vitro. It also decreases serum-stimulated growth (IC50 = 1.8 µM after 8 days) and migration (IC50 = 4.5 µM) of rat aortic smooth muscle cells.
