  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。

  Lack of novel antifungal agents and severe drug resistance have led to high incidence and associated mortality of invasive fungal infections. To tackle the challenges, novel antifungal agents with new chemotype, fungicidal activity and anti-resistant potency are highly desirable. On the basis of our previously identified simplified analogue of antifungal natural product sampangine, systemic structure-activity relationships were clarified and two novel derivatives showed promising features as novel antifungal lead compounds. Compounds 22b and 22c showed good fungicidal activity against both fluconazole-sensitive and fluconazole-resistant Candida albicans strains. Moreover, they were proven to be potent inhibitors of Candida albicans biofilm formation and yeast-to-hypha morphological transition by down-regulating biofilm-associated genes. In a rat vaginal Candida albicans infection model, compounds 22b and 22c showed excellent therapeutic effects with low toxicity. The results highlighted the potential of sampangine derivatives to overcome fluconazole-related and biofilm-related drug resistance. (C) 2017 Elsevier Masson SAS. All rights reserved.
