NU6027 is a potent inhibitor of cellular ATR activity with the IC50 of 6.7 μM.
The ataxia telangiectasia mutated and Rad3-related kinase (ATR) has a crucial role in the stalled replication forks signalling and DNA damage to cell cycle checkpoints and DNA repair. ATR was recognised as an key target for cancer therapy, however, its inhibitors have proved elusive. NU6027, which was originally developed as a CDK2 inhibitor, inhibits ATR.
In vitro: NU6027 is a potent inhibitor of cellular ATR activity with the IC50 of 6.7 μM and enhanced the cytotoxicity of hydroxyurea and cisplatin in an ATR-dependent manner. NU6027 attenuated G2/M phase arrest with DNA damage, inhibited the formation of RAD51 focus and increased the cytotoxicity of the major classes of DNA-damaging cytotoxic therapy but not paclitaxel and antimitotic. In A2780 cells, cisplatin sensitisation was greatest in cells with functional p53 and mismatch repair and sensitisation to temozolomide was greatest in p53 mutant cells with functional mismatch repair. More importantly, NU6027 was found to be synthetically lethal when DNA single-strand break repair is impaired either through poly(ADP-ribose) polymerase (PARP) inhibition or defects in XRCC1 [1].
In vivo: Currently no in-vivo data are available.
Clinical trial: NU6027 is still in preclinical development stage and no clinicl trial is ongoing currently.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
