  5-Arylidenethioxothiazolidinones as Inhibitors of Tyrosyl–DNA Phosphodiesterase I

  摘要：

  Tyrosyl-DNA phosphodiesterase I (Tdp1) is a cellular enzyme that repairs the irreversible topoisomerase I (Top1)-DNA complexes and confers chemotherapeutic resistance to Top1 inhibitors. Inhibiting Tdp1 provides an attractive approach to potentiating clinically used Top1 inhibitors. However, despite recent efforts in studying Tdp1 as a therapeutic target, its inhibition remains poorly understood and largely underexplored. We describe herein the discovery of arylidene thioxothiazolidinone as a scaffold for potent Tdp1 inhibitors based on an initial tyrphostin lead compound 8. Through structure-activity relationship (SAR) studies we demonstrated that arylidene thioxothiazolidinones inhibit Tdp1 and identified compound 50 as a submicromolar inhibitor of Tdp1 (IC50 = 0.87 mu M). Molecular modeling provided insight into key interactions essential for observed activities. Some derivatives were also active against endogenous Tdp1 in whole cell extracts. These findings contribute to advancing the understanding on Tdp1 inhibition.

  Tdp1 inhibitors of Formula (I) and methods of using those inhibitors to treat cancer are provided in this disclosure. R1 is hydrogen or lower alkyl and G is a substituted phenyl or optionally substituted heteroaryl group. The disclosed Tdp1 inhibitors may be used alone to treat cancer, but may also be used in combination with another active agent, such as camptothecin or a camptothecin analogue.

  本公开提供的是公式（I）的Tdp1抑制剂及其用于治疗癌症的方法。其中，R1为氢或低碳基，G为取代苯基或可选取代的杂环芳基基团。所披露的Tdp1抑制剂可单独用于治疗癌症，也可与另一种活性剂（例如喜树碱或喜树碱类似物）联合使用。
