Toceranib Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Toceranib is a multitargeted indolinone receptor tyrosine kinase (RTK) inhibitor. Toceranib exhibited activity against a variety of spontaneous malignancies in canine such as mast cell tumors, mixed mammary carcinomas, soft tissue sarcomas, and multiple myeloma.

Biologische Aktivität
toceranib is an inhibitor which blocks various tyrosine kinases expressed on the cell surface. receptor tyrosine kinases (rtks) are excellent candidates for molecular targeted therapy, because they play key roles in controlling cell proliferation and survival and are frequently dysregulated in a variety of malignancies.
Biochem/physiol Actions
Toceranib (SU11654) is a protein tyrosine kinase inhibitor that selectively targets stem cell factor receptor c-kit, including all forms of mutant Kit, as well as PDGFR and VEGFR. Toceranib exhibited Ki values of 5 nM for PDGFR and 6 nM for VEGFR. Toceranib phosphate is approved for use in mast cell cancer in dogs.
in vitro
toceranib inhibited kit phosphorylation and cell proliferation in a dose-dependent manner in the treatment-naïve, parental c2 line (ic50 < 10 nm). in addition, chronic toc exposure resulted in c-kit mrna and kit protein overexpression in the toc-resistant sublines [1].
in vivo
fourteen dogs with advanced mast cell tumors (mcts) were enrolled in a prevoius study, among which 11 dogs were evaluable for kit target modulation. of these, eight mcts showed reduced levels of phosphorylated kit relative to total kit after treatment with toceranib, compared with pretreatment biopsies. all four evaluable mcts expressing itd mutant c-kit showed modulation of kit phosphorylation, as did four of seven tumors expressing non-itd c-kit. [2].
