We identified a di-substituted triazolopyrimidine with anti-tubercular activity against Mycobacterium tuberculosis. Three segments of the scaffold were examined rationally to establish a structure-activity relationship with the goal of improving potency and maintaining good physicochemical properties. A number of compounds displayed sub-micromolar activity against Mycobacterium tuberculosis with no

A diversity of new 7‐substituted[1,2,4]triazolo[1,5‐a]pyrimidine and 6‐substituted[1,2,4]triazolo[1,5‐a]pyrimidine‐7‐amine derivatives has been synthesized via reaction of 3‐amino‐[1,2,4]triazole with enaminonitriles and enaminones. The regio orientation and the structure of the products were confirmed by spectral and analytical data and synthesis via an alternative route. The procedure proved to be
已经开发了多种新的7-取代的[1,2,4]三唑[1,5- a ]嘧啶和6-取代的[1,2,4]三唑[1,5 - a ]嘧啶-7-胺衍生物通过3-氨基[1,2,4]三唑与烯胺腈和烯胺酮的反应合成。产物的区域取向和结构通过光谱和分析数据以及通过另一种途径的合成得到证实。该方法被证明是简单,有效和高收率的,并且获得了[1,2,4]三唑并[1,5- a ]嘧啶的多样性。

progression of pathological angiogenesis in various types of malignancies, making it an attractive therapeutic target in cancer treatment. In the present work, we report the synthesis of 1,4-disubstituted 1,2,3-triazoles and 1,2,4-triazolo[1, 5-a]pyrimidine derivatives via copper (I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction and screened for their anticancer activity against MCF7 cells. We identified
血管内皮生长因子(VEGF)及其受体(VEGFR)对于组织和新脉管系统的生理功能至关重要。VEGFR信号转导与各种类型的恶性肿瘤中病理性血管生成的进展相关,使其成为癌症治疗中有吸引力的治疗靶标。在本工作中,我们报告了通过铜(I)催化的叠氮化物-炔烃环加成反应合成1,4-二取代的1,2,3-三唑和1,2,4-三唑并[1,5- a ]嘧啶衍生物(CuAAC)反应并筛选其对MCF7细胞的抗癌活性。我们确定了1-(2'-乙氧基-4'-氟-[1,1'-联苯] -4-基)-4-苯基-1H-1,2,3-三唑(EFT)是针对带有IC 50的MCF7细胞系值为1.69 µM。进一步的评估表明,EFT对石川,MDA-MB-231和BT474细胞产生细胞毒性,IC 50值分别为1.97、4.81和4.08 µM。但是,EFT不会在正常肺上皮(BEAS-2B)细胞中诱导细胞毒性。以前的报道表明1,2,3-三唑是V
