of a conformational restriction strategy. For that purpose we have successfully synthesized novel tricyclic imidazo[1,2-a]pyrazine derivatives as PI3K inhibitors. This new class of compounds had enable the exploration of the solvent-accessible region within PI3K and resulted in the identification of molecule 8q with the best selectivity PI3Kα/δ isoform profile in vitro, and promising in vivo PK data
磷酸肌醇3-激酶(PI3K)参与多种疾病,特别是在肿瘤领域,已将其选为过去二十年来最受研究的治疗靶标之一。工业界和学术界已经开发出许多不同的抑制剂类别,它们在PI3K系列中具有不同的选择性。在本手稿中,我们报告通过应用构象限制策略进一步研究我们的PI3K抑制剂ETP-46321(MartínezGonzález等,2012)1。为此,我们已经成功合成了新型的三环咪唑并[1,2-a]吡嗪衍生物作为PI3K抑制剂。
