Based on our previous study on the development of the furoquinolinedione and isoxazoloquinolinedione TDP2 inhibitors, the further structure-activity relationship (SAR) was studied in this work. A series of furoquinolinedione and isoxazoloquinolinedione derivatives were synthesized and tested for enzyme inhibitions. Enzyme-based assays indicated that isoxazoloquinolinedione derivatives selectively showed
基于我们之前对呋喃喹啉二酮和异恶唑并喹啉二酮 TDP2 抑制剂开发的研究,本工作进一步研究了构效关系 (SAR)。合成了一系列呋喃喹啉二酮和异恶唑并喹啉二酮衍生物并测试了酶抑制作用。基于酶的测定表明,异恶唑并喹啉二酮衍生物在亚微摩尔范围内选择性地显示出高 TDP2 抑制活性,呋喃喹啉二酮衍生物在低微摩尔范围内选择性地显示出高 TDP2 抑制活性。最有效的 3-(3,4-二甲氧基苯基) 异恶唑并[4,5-g]喹啉-4,9-二酮 ( 70 ) 显示出 TDP2 抑制活性,IC 50为 0.46 ± 0.15 μM。这项工作将促进未来发现异恶唑并喹啉二酮 TDP2 选择性抑制剂的努力。
