six kinases at 10 µM. Against the triple mutant, EGFR T790M C797S L858R, compounds 9–12 exhibited complete inhibition at 10 µM and nearly complete inhibition at 1 µM. The target compounds were also evaluated using the MTT assay to determine their cytotoxic activity against human non-small cell lung cancer cells (PC9, PC9GR and H460) and mouse leukemic cells (Ba/F3 WT and Ba/F3T 3151). Overall, 7, 9–12
合成了一系列来自WZ4002的32个
苯胺嘧啶,并使用LanthaScreen结合测定法(
EGFR d746 – 750)或Z'LYTE测定法(
EGFR-WT,
EGFR d746 – 750,
EGFR)评价了六种不同
EGFR激酶的抑制百分比T790M,
EGFR T790M L858R,
EGFR C797S和
EGFR T790M L858R C797S)。邻羟基乙酰胺10显示出所有六个激酶的完全抑制在10μM。对三突变体,
EGFR T790M C797S L858R,化合物9 - 12在10 µM时表现出完全抑制,在1 µM时表现出几乎完全抑制。还使用M
TT分析法评估了目标化合物,以确定其对人非小细胞肺癌细胞(PC9,PC9GR和H460)和小鼠白血病细胞(Ba / F3 WT和Ba / F3T 3151)的细胞毒活性。总体而言,7,9 - 12,30和31被认为是在所有五种
细胞系的最有效的化合物。
