  DNA damage repair enzymes are promising targets in the development of new therapeutic agents for a wide range of cancers and potentially other diseases. The enzyme poly(ADP-ribose) glycohydrolase (PARG) plays a pivotal role in the regulation of DNA repair mechanisms; however, the lack of potent drug-like inhibitors for use in cellular and in vivo models has limited the investigation of its potential

  DNA损伤修复酶是开发用于多种癌症和其他潜在疾病的新型治疗剂的有希望的目标。聚（ADP-核糖）糖水解酶（PARG）在调节DNA修复机制中起着关键作用。然而，由于缺乏用于细胞和体内模型的有效药物样抑制剂，限制了其作为新型治疗靶标的潜力的研究。通过将人类PARG的晶体结构与弱活性和具有细胞毒性的蒽醌8a配合使用，已通过基于结构的虚拟筛选和库设计方法鉴定了新型喹唑啉二酮磺酰胺类PARG抑制剂。1-氧杂-3-基甲基衍生物33d和35d选择用于体内的初步研究。X射线晶体结构有助于合理化所观察到的这些新型抑制剂的构效关系。

  A series of 7 beta-[(Z)-2-(2-aminothiazol-4-yl)-2-hydroxyiminoacetamido]-3-(heteroarylmethylthio)cephalosporins was designed, synthesized and evaluated for antibacterial activity and oral absorption in rats. Antibacterial activity was markedly influenced by the structure of the heteroaromatic ring moiety. Oral absorption was influenced by the heteroaromatic ring moiety as well as by the arrangement of heteroatoms. Among these compounds, FK041 (2o). having a 4-pyrazolylmethylthio moiety, showed potent antibacterial activity against both Gram-positive and Gram-negative bacteria including Haemophilus influenzae. Further, it showed higher oral absorption than CFDN. (C) 2001 Elsevier Science Ltd. All rights reserved.
