生物活性
WP1066是一种新型JAK2和STAT3抑制剂,IC50分别为2.30 μM和2.43 μM;对JAK2, STAT3, STAT5和ERK1/2而非JAK1和JAK3具有抑制活性。WP1066能显著抑制携带JAK2 V617F突变亚型的HEL细胞的生长,这种抑制是剂量依赖型的,它的IC20, IC50和 IC80分别是0.8, 2.3 和3.8 μM。在表达JAK2 V617F突变亚型的急性白血病HEL细胞中0.5, 1.0, 2.0, 3.0, 或 4.0 μM浓度的WP1066则可以抑制JAK2, STAT3, STAT5和ERK1/2的磷酸化,但不会抑制JAK1 和JAK3的磷酸化。 WP1066的浓度在0.5 到 3.0 μM之间以剂量依赖的方式抑制从病人体内获得的AML形细胞以及AML 细胞系 OCIM2和K562的增殖。

方法 | Cell viability was assessed by the MTS assay using the Cell Titer96 AQueous Non-Radioactive Cell Proliferation Assay (Promega, Madison, WI, USA) according to the manufacturer's instructions. Briefly, cells were incubated overnight in 96-well plates (3 × 103cells/well) and then treated for 48 h with the indicated concentration of WP1066 (in DMSO) or with the corresponding amount of DMSO. Two hours after adding MTS, plates were read in a microplate autoreader at a wavelength of 490 nm. The results were expressed as the mean optical density of the six-well set for each group, and the plates were measured twice with similar results. For cell counts, after being incubated overnight in six-well plates (2 × 104cells/well in triplicate), cells were treated with 2.5 or 5 μm WP1066 or with the corresponding amount of DMSO. Total cell numbers in three independent wells in each group were counted at the indicated time by using a hemocytometer, and the mean value of four fields was recorded. |

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
