生物活性
AZD1480是一种新型,ATP竞争性的JAK2抑制剂,IC50为0.26 nM,选择性作用于JAK3和Tyk2,对JAK1的作用较弱。5μM AZD1480诱导细胞周期停在G2/M期,且通过抑制Aurora激酶而诱导细胞死亡。AZD1480是JAK2的有效抑制剂,作用于人类多发性骨髓瘤细胞,可以抑制生长,存活,FGFR3 和 STAT3信号,及下游靶点,包括 Cyclin D2。在低微摩尔浓度时,AZD1480抑制细胞增殖和诱导骨髓瘤细胞系凋亡。

细胞系 | Renca or 786-O cells |
方法 | Cell viability assay. Renca or 786-O cells suspended in DMEM medium with 5% FBS were seeded in 96-well plates (5,000 per well) to allow adhesion and then treated with DMSO or AZD1480 for 48 h. Cell viability was determined by MTS assay (Promega, Madison, WI) according to instructions. Absorbance at 490 nm was measured with Mikrotek Laborsysteme (Overath, Germany). Mouse ECs and splenic CD11b+/c– myeloid cells enriched from tumor bearing mice were cultured in 5% FBS 1640 RPMI medium. HUVECs were cultured on collagen 1-coated plates in complete medium (Clonetics). All cells are treated with DMSO and AZD1480 at various doses for 24 h. Cell viability was determined by counting cell number manually. All the experiments were repeated 3 times. |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
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。
