NU6027（Cat No.:R022200）is a selective inhibitor of the cyclin-dependent kinase 2 (CDK2), a crucial enzyme involved in cell cycle regulation. By inhibiting CDK2, NU6027 aims to prevent cancer cells from proliferating, particularly in tumors that are dependent on this pathway. It has shown promise in preclinical studies against various cancer types, including breast and prostate cancers. The compound is being investigated for its potential to enhance the efficacy of existing therapies. Side effects are still being assessed, but targeted approaches like NU6027 aim to minimize toxicity compared to traditional chemotherapy.

Identification and evaluation of a potent novel ATR inhibitor, NU6027, in breast and ovarian cancer cell lines.Peasland A,Wang LZ,Rowling E,Kyle S,Chen T,Hopkins A,Cliby WA,Sarkaria J,Beale G,Edmondson RJ,Curtin NJ, PMID: 21730979 PMCID: PMC3172902 DOI: 10.1038/bjc.2011.243 </br><span>Abstract:</span> BACKGROUND: The ataxia telangiectasia mutated and Rad3-related kinase (ATR) has a key role in the signalling of stalled replication forks and DNA damage to cell cycle checkpoints and DNA repair. It has long been recognised as an important target for cancer therapy but inhibitors have proved elusive. As NU6027, originally developed as a CDK2 inhibitor, potentiated cisplatin in a CDK2-independent manner we postulated that it may inhibit ATR.METHODS: Cellular ATR kinase activity was determined by CHK1 phosphorylation in human fibroblasts with inducible dominant-negative ATR-kinase dead expression and human breast cancer MCF7 cells. Cell cycle effects and chemo- and radiopotentiation by NU6027 were determined in MCF7 cells and the role of mismatch repair and p53 was determined in isogenically matched ovarian cancer A2780 cells.RESULTS: NU6027 is a potent inhibitor of cellular ATR activity (IC(50)=6.7 μM) and enhanced hydroxyurea and cisplatin cytotoxicity in an ATR-dependent manner. NU6027 attenuated G2/M arrest following DNA damage, inhibited RAD51 focus formation and increased the cytotoxicity of the major classes of DNA-damaging anticancer cytotoxic therapy but not the antimitotic, paclitaxel. In A2780 cells sensitisation to cisplatin was greatest in cells with functional p53 and mismatch repair (MMR) and sensitisation to temozolomide was greatest in p53 mutant cells with functional MMR. Importantly, NU6027 was synthetically lethal when DNA single-strand break repair is impaired either through poly(ADP-ribose) polymerase (PARP) inhibition or defects in XRCC1.CONCLUSION: NU6027 inhibits ATR, impairing G2/M arrest and homologous recombination thus increasing sensitivity to DNA-damaging agents and PARP inhibitors. It provides proof of concept data for clinical development of ATR inhibitors. |
