ATP-competitive, potent and selective platelet-derived growth factor receptor (PDGFR) inhibitor against tumor growths in vivo.
CP-673451 is an ATP-competitive, potent and selective platelet-derived growth factor receptor inhibitor (PDGFR1 (β)/PDGFR2 (α) IC50 = 1/10 nM with 10 μM ATP; IC50 = 252 nM/c-kit, 450 nM/VEGFR-1/2; >450-fold reduced potency toward other angiogenic receptors and non-receptor kinases). CP-673451 potently inhibits PDGF-BB-induced receptor phosphorylation (IC50 = 6.4 nM; PDGFR1 transfectant) and effectively suppress human cancer xenografts-derived tumor in mice in vivo (ED50 ≤33 mg/kg via b.i.d. or q.d. p.o.) by inhibiting PDGFR phosphorylation and angiogenesis in tumor tissues.
CP-673,451 is a potent inhibitor of platelet-derived growth factor beta-receptor (PDGFR-beta) kinase- and PDGF-BB-stimulated autophosphorylation of PDGFR-beta in cells (IC(50) = 1 nmol/L) being more than 450-fold selective for PDGFR-beta versus other angiogenic receptors (e.g., vascular endothelial growth factor receptor

Cholangiocarcinoma (CCA) is an aggressive tumour with a poor prognosis due to its late clinical presentation and the lack of effective non-surgical therapies. Previous studies have reported that platelets are implicated in tumour invasion and metastasis, while their role and

Hepatomegaly can be triggered by insulin and insulin-unrelated etiologies. Insulin acts via AKT, but how other challenges cause hepatomegaly is unknown. Since many hepatomegaly-inducing toxicants and stressors activate NRF2, we examined the effect of NRF2 activation on liver size and

Lack of insight into the identity of the cells that initiate metastasis hampers the development of antimetastatic therapies. Only a tiny fraction of tumor cells termed metastasis-initiating cells (MICs) are able to successfully seed metastases, causing recurrence and therapeutic resistance.

Lung cancer is the leading cause of cancer mortality in the world. Although some advances in lung cancer therapy have been made, patient survival is still poor. The platelet-derived growth factor receptors (PDGFRs) and their ligands play critical roles in
