生物活性
IU1-47 is a potent and specific USP14 inhibitor with an IC50 of 0.6 μM. IU1-47 inhibits IsoT/USP5 with an IC50 of 20 μM. IU1-47 stimulates tau degradation principally via the ubiquitin-proteasome system. IU1-47 (3 μM, 10 and 30 μM; 48 hours) significantly decreases Tau and phosphotau species Ser-202/Thr-205 levels in murine cortical primary neurons. The level of USP14 itself does not change.

方法 |
Murine cortical primary neurons (DIV5) isolated from APPSwe/P301L transgenic animals were incubated with the indicated doses of IU1-47 for 48 h, then harvested, and processed as above. Immunoblots developed with IRDye-conjugated secondary antibodies show the level of total tau and of several specific phospho (P)-tau species upon IU1-47 treatment. Phosphoepitopes are indicated in parentheses. The top three blots are from one gel; the bottom four blots are from another gel (left). The USP14 blot shows that no change in USP14 protein level was observed upon IU1-47 treatment. Values in the graphs represent an average of two biological replicates representing cortical neurons from littermates. |

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。
