Western blot analysis using 4G10 and anti-FLT3 antibody after immunoprecipitation with anti-FLT3 antibody and Western blot analysis of phospho-ERK (pERK) and ERK performed on whole cell lysates from HB119 and Molm14 cells. Cells were exposed to 100 nM crenolanib for 60 min.

Concurrent treatment with Crenolanib and AG1478 enhances apoptosis as monitored by Caspase-3 and PARP-1 cleavage, either in GBM c-CSC or p-CSC, except for p-CSC3. Instead, Crenolanib alone is less effective in inducing apoptosis either in c-CSC or p-CSC pools. High PDGFR α expression is a distinctive feature of p-CSC pools and its expression is de-repressed following AG1478 treatment clearly evident in case 1 and 2, while its expression is downmodulated following Crenolanib treatment in all cases reported.

Combined treatment with Pim and FLT3 inhibitors abrogates growth of Ba/F3-ITD cells. Ba/F3-ITD cells were cultured at 1 × 105/mL with the Pim kinase inhibitor AZD1208 at 1 μmol/L and/or the FLT3 inhibitors quizartinib at 1 nmol/L, sorafenib at 2.5 nmol/L, crenolanib at 20 nmol/L or gilteritinib at 15 nmol/L, or DMSO control. Cell counts measured at 24, 48, and 72 hours were normalized to 0-hour control. Line graphs represent means ± SEM of triplicate values.

NSG mice were inoculated with 1x106 MOLM-13 cells (ffluc+GFP+662 ) and on day 7 were treated with 5x106 FLT3-CAR T-cells alone (CD4+:CD8+ ratio = 1:1), crenolanib alone (15mg/kg body weight as i.p. injection), or both (combination), or were left untreated. The first dose of crenolanib was given on day 7 and mice received 15 doses (Monday-Friday) for 3 consecutive weeks.

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。[1] 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。[2] |
