Toceranib phosphate

CAS No. : 874819-74-6

MCE 站：Toceranib phosphate

产品活性：Toceranib phosphate (SU11654 phosphate) 是一种具有口服活性的酪氨酸激酶 (RTK) 受体抑制剂，能有效抑制 PDGFR，VEGFR，Kit，抑制 PDGFRβ 和 Flk-1/KDR 的 K_i 值分别为 5 nM 和 6 nM。Toceranib phosphate 具有抗肿瘤和抗血管生成活性，可用于犬肥大细胞肿瘤的研究。

研究领域：Protein Tyrosine Kinase/RTK

作用靶点：PDGFR  |  VEGFR  |  c-Kit

In Vitro: Toceranib phosphate (PHA 291639 phosphate) is a selective inhibitor of the tyrosine kinase activity of several members of the split kinase RTK family, including PDGFR and Flk-1/KDR, with K_is of 5 and 6 nM, respectively.
To explore mechanisms of acquired Toceranib (TOC) resistance in canine MCT, three resistant sublines are generated from the Toceranib-sensitive exon 11 ITD c-kit mutant C2 cell line designated TR1, TR2, and TR3. Growth of the parental C2 cells is inhibited by Toceranib in a dose-dependent manner with an IC₅₀ of <10 nM. In contrast, TR1, TR2, and TR3 sublines are resistant to inhibition by Toceranib (IC₅₀>?1,000 nM). Sensitivity to three other KIT RTK inhibitors is similar to the observed resistance to Toceranib. The parental line as well as all three sublines retains sensitivity to the cytotoxic agents vinblastine (VBL) and CCNU. Following 72 hr culture in the presence of increasing concentrations of Toceranib, treatment na?ve, parental C2 cells detach from the culture flask and become rounded, shrunken, and clumped with increased exposure to Toceranib. In contrast, Toceranib-induced morphologic differences are not identified in the resistant sublines.

In Vivo: Administration of Toceranib phosphate (PHA 291639 phosphate) significantly decreases the number and percentage of Treg in the peripheral blood of dogs with cancer. Dogs receiving Toceranib phosphate (PHA 291639 phosphate) and cyclophosphamide (CYC) demonstrate a significant increase in serum concentrations of IFN-γ, which is inversely correlated with Treg numbers after 6 weeks of combination treatment.
