important role in DNA damage response and is considered a potential target in cancer therapies. In this study, a goal-directed molecular generation approach based on ligand similarity and target specificity was applied to sample active molecules, and they were screened virtually to identify the theoretical lead compound 7a, which was later shown to inhibit ATM adequately. However, there is a main concern about
ATM 在 DNA 损伤反应中发挥着重要作用,被认为是癌症治疗的潜在靶点。在这项研究中,基于配体相似性和靶标特异性的目标导向分子生成方法应用于活性分子样品,并对它们进行虚拟筛选,以鉴定理论先导化合物 7a ,后来证明该化合物可以充分抑制ATM。然而,人们主要担心其体外代谢稳定性差。随后进行了优化,以提高对 ATM 的效力和选择性,并减弱体外肝脏清除率,最终鉴定出10r具有纳摩尔级 ATM 抑制作用、对放疗和化疗药物优异的细胞敏感性以及令人印象深刻的药代动力学特征。此外,10r与伊立替康联合在SW620异种移植模型中表现出协同抗肿瘤功效,表明它可能是一种有前途的联合化疗治疗癌症的候选药物。
