常见问题列表

生物活性
Crenolanib (CP-868596)是一种有效的,选择性的PDGFRα/β抑制剂,Kd为2.1 nM/3.2 nM,也有效抑制FLT3,对D842V突变型而不是V561D突变型敏感,作用于PDGFR比作用于c-Kit, VEGFR-2, TIE-2, FGFR-2, EGFR, erbB2,和Src选择性高100倍以上。
体外研究
Crenolanib is significantly more potent than imatinib in inhibiting the kinase activity of imatinib-resistant PDGFRα kinases (D842I, D842V, D842Y, D1842-843IM, and deletion I843). Crenolanib is 135-fold more otent than imatinib against D842V in the isogenic model system, with an IC50 of approximately 10 nM. Crenolanib inhibits the kinase activity of the fusion oncogene in EOL-1 cell line, which is derived from a patient with chronic eosinophilic leukemia and expresses the constitutively activated FIP1L1- PDGFRα fusion kinase, with IC50 = 21 nM. Crenolanib also inhibits the proliferation of EOL-1 cells with IC50 = 0.2 pM. Crenolanib inhibits the activation of V561D or D842V-mutant kinases expressed in BaF3 cells with IC50 with 85 nM or 272 nM, respectively. Crenolanib inhibits PDGFRα activation in H1703 non-small cell lung cancer cell line which has 24-fold amplification of the 4q12 region that contains the PDGFRα locus, with IC50 with 26 nM. Crenolanib is an orally bioavailable, highly potent and selective PDGFR TKI. Crenolanib is a benzimidazole compound that has IC50s of 0.9 nM and 1.8 nM for PDGFRA and PDGFRB, respectively.

体外研究

Crenolanib显著比imatinib有效,能够抑制对imatinib耐药的PDGFRα激酶(D842I,D842V,D842Y,D1842-843IM,和缺失I843)活性。Crenolanib作用于同基因模型系统中D842V,比imatinib有效135倍,IC50大约为10 nM。Crenolanib抑制EOL-1细胞中融合致癌基因的激酶活性,其衍生自慢性噬酸细胞白血病患者,且表达持续活化的FIP1L1- PDGFRα融合激酶,IC50 = 21 nM。Crenolanib也会抑制EOL-1细胞的增殖,IC50 = 0.2 pM。Crenolanib抑制在BaF3细胞中表达的V561D或D842V突变激酶的活化,IC50分别为85 nM或272 nM。Crenolanib抑制H1703非小细胞肺癌细胞系中PDGFRα活化,其能够使包含PDGFRα基因座的4q12区域扩增24倍,IC50为26 nM。 Crenolanib是一种口服具有生物活性的,高度有效的,选择性PDGFR TKI。Crenolanib是苯并咪唑化合物,对PDGFRA和PDGFRB的IC50s分别为0.9 nM和1.8 nM。
