SKLB-197是一种有用且高度选择性的ATR抑制剂，，，PK研究通过yl23455永利举行

Ataxia telangiectasia mutated and Rad3-related (ATR) kinase is an important regulator of the DNA damage response, especially in response to replication stress. SKLB-197 is a potent and highly selective ATR inhibitor with an IC50 value of 13 nM. SKLB-197, exhibits good pharmacokinetic properties, could be a promising lead compound for drug discovery targeting ATR. The pharmacokinetic (PK) studies were performed by Medicilon.
