The DNA repair enzyme AAG has been shown in mice to promote tissue necrosis in response to ischaemic reperfusion or treatment with alkylating agents. A chemical probe inhibitor is required for investigations of the biological mechanism causing this phenomenon and as a lead for drugs that are potentially protective against tissue damage from organ failure and transplantation, and alkylative chemotherapy
DNA修复酶AAG已在小鼠中显示出响应于缺血性再灌注或用烷基化剂治疗而促进组织坏死。对于引起这种现象的生物学机制的研究,化学抑制剂是必需的,并且它是潜在保护器官免受器官衰竭和移植以及烷基化化学疗法伤害的药物的先导。在本文中,我们描述了选择芳基甲基吡咯烷酮作为抑制剂的合适氮杂核苷模拟物背后的原理,然后合成了它们,并首次使用了基于微孔板的测定方法来量化其对AAG的抑制作用。我们最后报告了咪唑-4-基甲基吡咯烷作为片段大小的AAG弱抑制剂的发现。
