生物活性
TA-01是一种有效的CK1和p38 MAPK抑制剂,对CK1ε,CK1δ和p38 MAPK的IC50值分别为6.4 nM,6.8 nM和6.7 nM。当在5μM下施用时,TA-01抑制剂抑制心脏发育。TA-01显示所有测试的中胚层标记物和心脏前标志物Isl-1的表达降低。

Human pluripotent stemcell lines HES-3 and H7 |
方法 |
Human pluripotent stemcell lines HES-3 and H7 were seeded at 2.5 × 106cells/12-ULA well in BSFS medium with cell line optimized concentrations of CHIR99021 for 24 h (Supplemental Fig. S7). Thereafter the 2,4,5-trisubstituted azoles or IWP-2 or IWR-1 were added at a concentration of 5 μM (2.5 μM for IWR-1) either from 1-8 days or from 4-8 days. Dissociated EBs showed an average of 50–60% NKX2-5+cells on day 11 when either 2,4,5-trisubstituted azoles, IWP-2 and IWR-1 were applied from 4-8 days i.e. at the post mesoderm stage. In comparison to premesoderm treatment only HES-3 showed high cardiomyocyte expansion fold with SB203580 (days 1-8) (Fig. 3A). To confirm that 2,4,5-trisubstituted azoles had no negative impact on cell viability, we analyzed the cell growth kinetics. EBs treated with IWP-2 and IWR-1 generated significantly fewer cells compared to 2,4,5-trisubstituted azoles in both cell lines (Fig. 3A). Metabolismrates of EBs measured with MTT showed an increase with TA-01 but not with IWR-1 and IWP-2 during the compound induction period. |

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。
