Text-mined interactions from Literome
Drevs et al., Cancer Res 2002
(Carcinoma, Renal Cell...) :
PTK787/ZK 222584, a specific
vascular endothelial growth factor-receptor tyrosine kinase
inhibitor , affects the anatomy of the tumor vascular bed and the functional vascular properties as detected by dynamic enhanced magnetic resonance imaging
Lin et al., Cancer Res 2002
(Multiple Myeloma) :
Importantly,
PTK787 also inhibits the increased MM cell proliferation and
increased IL-6 and
VEGF secretion in cultures of MM cells adherent to bone marrow stem cells
Siddiqui et al., Hematol J 2002
(Neoplasms) :
We conclude that Hb-induced synthesis of
VEGF in TF-bearing malignant cells is
mediated by
protein tyrosine kinase and by MAP-kinase pathways
Drevs et al., IDrugs 2003
:
PTK/ZK , a
VEGF receptor tyrosine kinase
inhibitor , is under development by Novartis AG and Schering AG as an inhibitor of angiogenesis for the potential treatment of various cancers
Tsai et al., Biochem Biophys Res Commun 2003
(Glioma) :
PTK inhibitors
blocked glioma proliferation and epidermal growth factor (EGF) induced
VEGF secretion, while H-7, a PKC inhibitor, inhibited both EGF induced and baseline VEGF secretion
Gray et al., Oncogene 2005
(Anoxia...) :
In normal fibroblasts, hypoxia induced activation of the
protein tyrosine kinase , Src, is
required for
VEGF expression
Hess-Stumpp et al., Chembiochem 2005
(Neoplasms) :
PTK 787/ZK 222584, a tyrosine kinase
inhibitor of all known
VEGF receptors, represses tumor growth with high efficacy
Liu et al., Cancer Res 2005
(Carcinoma, Hepatocellular...) :
This study examined the angiogenesis dependent and angiogenesis independent activities of
PTK787/ZK222584 ( PTK787 ) , a tyrosine kinase
inhibitor of
VEGF receptors, in nude mice bearing human hepatocellular carcinoma xenografts
Rudin et al., NMR Biomed 2005
(Melanoma...) :
PTK787/ZK222584 , a tyrosine kinase
inhibitor of
vascular endothelial growth factor receptor, reduces uptake of the contrast agent GdDOTA by murine orthotopic B16/BL6 melanoma tumours and inhibits their growth in vivo
Mross et al., Eur J Cancer 2005
(Liver Neoplasms...) :
Phase I clinical and pharmacokinetic study of
PTK/ZK , a multiple
VEGF receptor
inhibitor , in patients with liver metastases from solid tumours
Yazici et al., Laryngoscope 2005
(Carcinoma, Squamous Cell...) :
PTK787 alone or in combination with CPT-11
reduced the phosphorylation of
VEGF-R in tumor cells and tumor associated endothelial cells, was associated with decreased microvessel density, a decreased proliferative index, and an increased apoptotic index
Bian et al., Exp Eye Res 2007
:
Moreover, TGF-beta2 induced RPE
VEGF secretion was significantly
reduced by inhibitors of mitogen activated protein ( MAP ) kinase ( MEK ) ( U0126 ), p38 ( SB202190 ), c-Jun NH2-terminal kinase (JNK), Sp600125,
protein tyrosine kinase ( PTK ) ( Genistein ), and phosphatidylinositol 3-kinase (PI3K) ( Ly294002 )
Giles et al., Leuk Res 2007
(Primary Myelofibrosis) :
PTK787/ZK 222584, a small molecule tyrosine kinase receptor
inhibitor of
vascular endothelial growth factor ( VEGF ), has modest activity in myelofibrosis with myeloid metaplasia
Dong et al., Biotechniques 2007
:
In a proof-of-principle experiment with
PTK/ZK , a small molecule
inhibitor of
vascular endothelial growth factor ( VEGF ) tyrosine kinase receptors, a strong correlation was observed between the decrease in bioluminescence ( 9.12-fold ) in treated mice and the actual decrease in microvessel density ( 9.16-fold ) measured after retrieval of the scaffolds and immunohistochemical staining of endothelial cells
Liu et al., Lab Invest 2009
(Disease Models, Animal...) :
PTK/ZK also induced cell cycle arrest, accompanied by increasing the expression of p27 ( Kip1 ) and downregulation of cyclin D1 and cyclin E. PTK/ZK significantly
inhibited vascular endothelial growth factor ( VEGF ) expression, as well as VEGF simulated cell proliferation and phosphorylation of Akt in activated HSCs
Schomber et al., Mol Cancer Ther 2009
(Disease Progression...) :
In Rip1Tag2 mice, tumor angiogenesis is predominantly mediated by
VEGF-A , and as expected,
PTK/ZK efficiently
impaired tumor blood vessel angiogenesis and tumor growth
Nijkamp et al., Ann Surg 2009
(Anoxia...) :
PTK787/ZK-222584 , a nonselective Vascular Endothelial Growth Factor (
VEGF ) -receptor
inhibitor , reduced RFA stimulated tumor growth and tumor growth in the RZ to a similar extent
Brandes et al., Eur J Cancer 2010
(Brain Neoplasms...) :
PTK787/ZK222584 ( PTK/ZK, vatalanib ), a multiple
VEGF receptor
inhibitor , blocks the intracellular tyrosine kinase activity of all known VEGF receptors and is therefore suitable for long-term therapy of pathologic tumour neovascularisation
