Purity: ≥98%
Biological Activity
VE 821 is a high affinity and selective ATP-competitive ATR inhibitor (Ki = 13 nM). Exhibits >75-fold selectivity for ATR over related kinases mTOR, DNA-PK, PI 3-Kγ and PIKKs (Ki values are >1, 2.2, 3.9 and 16 μM, respectively) and a panel of other kinases. Induces cell death in colon cancer cell lines in vitro and sensitizes tumor cells to treatment with DNA damaging anticancer agents.Technical Data
