What is AZ20?

Description

AZ20 (1233339-22-4) is a potent and highly selective inhibitor of Ataxia telangiectasia mutated and RAD3-related (ATR) kinase (IC50?= 5 nM in vitro; IC50?= 50 nM in HT29 colorectal adenocarcinoma cells).1?Combination therapy with AZ20 and gemcitabine resulted in synergistic inhibition of tumor cell growth and cell death initiation in pancreatic cancer cell lines.2

The Uses of AZ20

AZ20 is a potent and selective inhibitor of ATR (ATM-Rad3-related) kinase with in vivo antitumor activity.

Definition

ChEBI: (3R)-4-[2-(1H-indol-4-yl)-6-(1-methylsulfonylcyclopropyl)-4-pyrimidinyl]-3-methylmorpholine is a member of indoles.

Storage

Store at -20°C
