Description:

WARNING: This product is for research use only, not for human or veterinary use.

Vatalanib, also known as PTK787, is an orally bioavailable anilinophthalazine with potential antineoplastic activity. Vatalanib binds to and inhibits the protein kinase domain of vascular endothelial growth factor receptors 1 and 2; both receptor tyrosine kinases are involved in angiogenesis. This agent also binds to and inhibits related receptor tyrosine kinases, including platelet-derived growth factor (PDGF) receptor, c-Kit, and c-Fms.

Biological target:

Vatalanib dihydrochloride (PTK787 dihydrochloride) is an inhibitor of VEGFR2/KDR with IC50 of 37 nM.

In vitro activity:

As shown in Figure 2a, PDGF induced a marked increase in HSC proliferation, which was significantly inhibited by PTK/ZK (Vatalanib) in a dose-dependent manner. Incubation of HSCs with PDGF also dramatically increased HSC migration in BIOCOAT MATRIGEL chamber systems, whereas PTK/ZK significantly blocked the migration of HSC induced by PDGF (Figure 2b, P<0.01). Figure 2c shows wounded HSC monolayers incubated in a medium containing PDGF without or with PTK/ZK. PDGF induced cell migration leading to wound closure 20 h after wounding. In the presence of PTK/ZK, PDGF-induced HSC migration in the wounded area was inhibited. Reference: Lab Invest. 2009 Oct; 89(10): 1152–1160. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2891536/

In vivo activity:

Histological quantification of the fluorescence intensity of tau phosphorylation (Fig. 1f) revealed a significant decrease in AT8 immunoreactivity in the hippocampus (CA1 and DG) of vatalanib-treated 5xFAD mice compared with vehicle-treated 5xFAD mice (Fig. 1c, f). The fluorescence intensity of AT100 was also significantly decreased in the cortex and hippocampus DG of vatalanib-treated 5xFAD mice (Fig. 1d, f). However, the fluorescence intensity of Tau5 was not altered by the administration of vatalanib (Fig. 1e, f). Thus, vatalanib administration in 5xFAD mice significantly reduced phospho-tauSer202, Thr205 and phospho-tauThr212, Ser214 without altering total tau levels.
