PD 407824_product_DataBase

Bioactivity

PD 407824 is a checkpoint kinase Chk1 and WEE1 inhibitor with IC50s of 47 and 97 nM, respectively. PD 407824 is a chemical BMP sensitizer and increases the sensitivity of cells to sub-threshold amounts of BMP4[1][2].

Invitro

PD 407824 is sufficient to block CHK1, leading to a significant down-regulation of p21, causing activation of CDK8/9, which in turn causes depletion of SMAD2/3[1].PD 407824 is selective for Chk1 and WEE1 over PKC and Cdk4 with IC50s of 3.4 µM and 3.75 µM, respectively[3].
