生物活性
AG-490 (Tyrphostin B42)是一种EGFR抑制剂,IC50为0.1 μM,作用于EGFR比作用于ErbB2选择性高135倍,对JAK2也有抑制作用,对Lck, Lyn, Btk, Syk和Src没有抑制活性。AG-490抑制EGF依赖的HER 14细胞增殖,IC50为3.5 μM。 与特异性作用于前B细胞急性白血病(ALL)细胞抑制组成型激活的JAK2 相一致,5 μM AG-490通过诱导程序性细胞死亡,几乎完全抑制所有ALL 细胞生长,而对正常造血功能不会造成有害影响。AG-490不会抑制Lck, Lyn, Btk, Syk, 和 Src激活。

实验结果 |
According to the results of Annexin V-FITC/PI staining (Figure 4A), the HSP70 siRNA group (55.2±3.1%) and AG490 group (60.8±4.2%) showed a remarkably higher cell apoptosis rate than the Blank group (14.5±1.3%) and NC siRNA group. |

实验结果 |
As displayed by the MTT assay (Figure 3A), both HSP70 siRNA and AG490 could effectively reduce the proliferation of Raji cells (24 h, 36 h, 48 h, and 72 h) (all P<0.05), and no significant difference was found between the Blank group and NC siRNA group regarding Raji cell proliferation at different time points. |
