3、M。IC50 & Target IC50: 0.66 M (tau), 1.2 M (A) 1体外研究 PE859 inhibits the heparin-induced aggregation of both 3RMBD and full length tau in a concentration-dependent manner. In each assay, the IC50 values calculated at the last measurement periods are 0.81 M,and 2.23 M, respectively. PE859 inhibits tau

4、aggregation through formation of beta-sheet structure 2.体内研究 PE859 could cross the blood-brain barrier and that PE859 could be distributed into the tissues of the centralnervous system. The maximum concentration of PE859 is 2.005 g/mL in the blood at 3 h and 1.428 g/g inthe brain at 6 h. PE859 delay

5、s onset and progression of the motor dysfunction in JNPL3 mice. PE859 delaysprogression of the motor dysfunction through the inhibition of accumulation of sarkosyl-insoluble tau. 2PROTOCOLKinase Assay 2 Tau aggregation is monitored using thioflavin T. The test compound (PE859), 10 M 3RMBD and 10 Mhe
