BAY-826 is a selective and potent TIE-2 inhibitor with Kd of 1.6 nM, respectively.
BAY-826 is a selective and potent inhibitor of TIE-2 (dissociation constant = 1.6 nM) and binds with similar high affinity to only 4 of 456 tested kinases, namely, TIE-1, DDR1, DDR2, and Serine/threonine-protein kinase 10 (LOK) (dissociation constant = 0.9, 0.4,1.3, and 5.9 nM).The high biochemical affinity for TIE-2 translates into very potent cellular mechanistic activity with an EC50 of about 1.3 nM for inhibition of TIE-2 autophosphorylation in human umbilical vein endothelial cells. The TIE-2 inhibitor BAY-826 is tested for its acute growth inhibitory as well as anti-clonogenic properties in all four mouse glioma cell lines. BAY-826 is highly selective against other angiogenic kinases, such as VEGFR, fibroblast growth factorreceptor (FGFR), or Platelet-derived growth factor receptor (PDGFR), and affects VEGF-stimulated proliferation of HUVEC only atμM concentrations, respectively.
TIE-2 inhibitor (BAY-826) improves tumor control in syngeneic mouse glioma models. Co-treatment with BAY-826 and irradiation is ineffective in one model (SMA-497), but provided synergistic prolongation of survival in another (SMA-560) cell. TIE- 2 inhibition may improve tumor response to treatment in highly vascularized tumors such as glioblastoma. We observe a reduction in tumor vessels upon BAY-826 treatment with highest vessel density[1].

Novel TIE-2 inhibitor BAY-826 displays in vivo efficacy in experimental syngeneic murine glioma models
J Neurochem 2017 Jan;140(1):170-182.PMID:27787897DOI:10.1111/jnc.13877
Targeting the vascular endothelial growth factor signaling axis in glioblastoma inevitably leads to tumor recurrence and a more aggressive phenotype. Therefore, other angiogenic pathways, like the angiopoietin/tunica interna endothelial cell kinase (TIE) signaling axis, have become additional targets for therapeutic intervention. Here, we explored whether targeting the receptor tyrosine kinase TIE-2 using a novel, highly potent, orally available small molecule TIE-2 inhibitor (BAY-826) improves tumor control in syngeneic mouse glioma models. BAY-826 inhibits TIE-2 phosphorylation in vitro and in vivo as demonstrated by suppression of Angiopoietin-1- or Na3 VO4 -induced TIE-2 phosphorylation in glioma cells or extracts of lungs from BAY-826-treated mice. There was a trend toward prolonged survival upon single-agent treatment in two of four models (SMA-497 and SMA-540) and there was a significant survival benefit in one model (SMA-560). Co-treatment with BAY-826 and irradiation was ineffective in one model (SMA-497), but provided synergistic prolongation of survival in another (SMA-560). Decreased vessel densities and increased leukocyte infiltration were observed, but might be independent processes as the effect was also observed in single treatment modalities. These data demonstrate that TIE-2 inhibition may improve tumor response to treatment in highly vascularized tumors such as glioblastoma.
