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.

Novel thiopyrano[2,3-d]thiazole derivatives were synthesized from 5-arylidene-4-thioxo-2-thiazolidinones and 2(5H)furanone in 62–79% yields via hetero-Diels–Alder reactions and related acylation-based tandem processes. The reaction of 5-(4-fluorophenyl)-4-thioxo-2-thiazolidinone with 2(5H)furanone was studied by DFT at the M06-2X/6-31+G(d,p) level. The stereo- and regioselectivities of cycloaddition
新型的噻吩并[2,3- d ]噻唑衍生物是由5-芳叉基-4-硫代-2-噻唑烷酮和2(5 H)呋喃酮通过杂Diels-Alder反应和相关的酰化反应合成的,产率为62-79%。串联过程。通过DFT在M06-2X / 6-31 + G(d,p)水平上研究了5-(4-氟苯基)-4-硫代氧-2-噻唑烷酮与2(5 H)呋喃酮的反应。环加成反应的立体选择性和区域选择性通过NMR光谱和单晶X射线衍射分析确定。
