potential intervention target for psoriasis. Here, we report the discovery of 5-((1H-indazol-3-yl) methylene)-2-thioxoimidazolidin-4-one derivatives as a new class of AHR agonists. Structure-activity relationship analyses led to the identification of the most active compound, 5- ((1H-indazol-3-yl)methylene) -3- (prop-2-yn-1-yl) -2-thiooimidazolidin-4-one (24e), which exhibited an EC50 value of 0.015 µM

Molecules bearing indole nucleus present diverse biological properties such as antitumor and anti-inflammatory activities that can be associated both to DNA and protein interactions. This study focused on the synthesis of new indolederivatives with thiazolidines and imidazolidine rings condensed as side chains as well as the evaluation of their ability to interact with the DNA and antitumor and topoisomerase
带有吲哚核的分子具有多种生物学特性,例如抗肿瘤和抗炎活性,可以与DNA和蛋白质的相互作用相关。这项研究的重点是合成带有噻唑烷和咪唑烷环缩合成侧链的新吲哚衍生物,并评估它们与DNA相互作用的能力以及抗肿瘤和拓扑异构酶的抑制活性。已成功合成所有衍生物,并通过质谱(MS),红外(IR),光谱1 H NMR,13 C NMR,COZY 1 H- 1 H和HSQC 1 H- 13阐明了它们的结构C.使用抗增殖MTT测定法评估了针对不同癌细胞系的抗肿瘤活性。使用溴化乙锭(EB)作为荧光探针,通过吸收光谱法和荧光技术分析DNA结合能力。在与ctDNA(小牛胸腺DNA)相互作用后,除了光谱最大值的蓝移或红移以外,还观察到了化合物的光谱性质发生了变化,具有低变色和增色作用。吲哚衍生物5-(1 H-吲哚-3-基亚甲基)-噻唑烷-2,4-二酮(4c)在针对所测乳腺线(T47D)的抗肿瘤试验中表现出最佳结果,IC
