GDC-0575（Cat No.:I027991）, also known as ARRY-575 or RG7741, is a potent and selective inhibitor of CHK1 (Checkpoint kinase 1). With an IC50 (half-maximal inhibitory concentration) of 1.2 nM, GDC-0575 effectively targets and inhibits the activity of CHK1, a key regulator of the DNA damage response pathway. By blocking CHK1, GDC-0575 disrupts cell cycle progression and DNA repair, leading to increased sensitivity of cancer cells to DNA-damaging agents.
