产品说明书产品使用指南

Masitinib (AB1010) 是一种有效的，生物口服可利用的，且选择性的 c-Kit 抑制剂 (对于人重组c-Kit，IC₅₀=200 nM)，它还抑制 PDGFRα/β (IC₅₀s=540/800 nM)，Lyn (对 LynB 的IC₅₀=510 nM)，Lck，较小程度上抑制 FGFR3 和 FAK。Masitinib (AB1010) 有抗增殖，促凋亡活性，且毒性低。

生物活性

Masitinib (AB1010) is a potent, orally bioavailable, and selective inhibitor of c-Kit (IC₅₀=200 nM for human recombinant c-Kit). It also inhibits PDGFRα/β (IC₅₀s=540/800 nM), Lyn (IC₅₀= 510 nM for LynB), Lck, and, to a lesser extent, FGFR3 and FAK. Masitinib (AB1010) has anti-proliferative, pro-apoptotic activity and low toxicity.

体外研究

Masitinib is a competitive inhibitor against ATP at concentrations ≤500 nM. Masitinib also potently inhibits recombinant PDGFR and the intracellular kinase Lyn, and to a lesser extent, fibroblast growth factor receptor 3. In contrast, masitinib demonstrates weak inhibition of Abl and c-Fms. Masitinib more strongly inhibits degranulation, cytokine production, and bone marrow mast cell migration than imatinib. In Ba/F3 cells expressing human wild-type Kit, masitinib inhibits SCF (stem cell factor)-induced cell proliferation with an IC₅₀ of 150 nM, while the IC₅₀ for inhibition of IL-3-stimulated proliferation is at approximately >10 µM. In Ba/F3 cells expressing PDGFRα, masitinib inhibits PDGF-BB-stimulated proliferation and PDGFRα tyrosine phosphorylation with IC₅₀ of 300 nM. Masitinib also causes inhibition of SCF-stimulated tyrosine phosphorylation of human Kit in mastocytoma cell-lines and BMMC. Masitinib inhibits Kit gain-of-function mutants, including V559D mutant and Δ27 mouse mutant with IC₅₀ of 3 and 5 nM in Ba/F3 cells. Masitinib inhibits the cell proliferation of mastocytoma cell lines including HMC-1α155 and FMA3 with IC₅₀ of 10 and 30 nM, respectively. Masitinib inhibits cell growth and PDGFR phosphorylation in two novel ISS cell lines, which suggest that Masitinib displays activity against both primary and metastatic ISS cell line and may aid in the clinical management of ISS.

体内研究

Masitinib inhibits tumour growth and increases the median survival time in Δ27-expressing Ba/F3 tumor models at 30 mg/kg, without cardiotoxicity or genotoxicity.
Masitinib (12.5 mg/kg/d, p.o.) increases overall TTP (time-to-tumor progression) compared with placebo in dogs.
