KRN 633 Chemical Properties,Uses,Production
Uses
KRN 633 is an ATP-competitive inhibitor of vascular endothlial growth factor receptor tyrosine kinase (VEGFR). KRN 633 also suppresses VEGF-dependent activation of MAPK and cell proliferation and demonstrates antitumor and antiangiogenic activity by inhibiting vessel formation and vascular permeability in human tumor xenograft models.
Uses
KRN 633 is an ATP-competitive inhibitor of VEGFR1/2/3 with IC50 of 170 nM/160 nM/125 nM and also inhibits PDGFRα/β with IC50 of 965 nM/9850 nM.
Biological Activity
krn 633 is a selective inhibitor of vegfr-1, vegfr-2 and vegfr-3 with ic50 value of 170 nm, 160 nm and 125 nm [1].vascular endothelial growth factor receptor (vegfr) is a protein and plays an important role in tumor angiogenesis by cooperating with its ligand vegf [1].krn 633 is a potent vegfr inhibitor. when tested with huvecs, krn 633 inhibited the cell proliferation that mediated by vegf with the ic50 value of 14.9 nmol/l and suppressed the capillary tube formation by ~50% at the dose of 10 nmol/l [1].in mid-pregnant mice model, krn633 was used at the dose of 5 mg/kg once daily from embryonic day 13.5 until the day of delivery and the effect on vascular growth was slightly delayed on postnatal day 4 (p4) and on p8 it was observed that krn633 resulted in the decreased numbers of central arteries and veins and abnormal branching of the central arteries [2]. when tested with athymic mouse xenograft ht29 cells model, administration of krn633 inhibited tumor growth as ~90% from the initial tumor volume rangs from 500-667 mm3, while had less effect du145 xenograft mouse models by inhibiting tumor angiogenesis and vascular permeability [1].
Biochem/physiol Actions
KRN633 is a cell-permeable; reversible and ATP-competitive inhibitor of vascular endothelial growth factor receptor tyrosine kinase (VEGFR) with IC50 values of 170, 160, and 125 nM for VEGFR-1, -2, -3, respectively. Krn633 inhibits PDGFR-α and c-Kit only at higher concentrations (IC50 = 0.97 and 4.33 μM, respectively) and is inactive towards a panel of 17 other kinases (IC50 >/= 10 μM).
