reactions have proven to be a decent strategy for the synthesis of complex molecules. Here, we report a catalyst-free method for the sulfenylation of 6-aminouracils which uses visible light as a source of clean and eco-energy. Uracils are pyrimidine derivatives and many of them are biologically potent. When 6-aminouracil and its derivatives are reacted with different thiols under the irradiation of a compact
biological profile of the synthesized compounds was evaluated against breast (MDAMB-231 and MCF-7) and colorectal (HCT-116) cancercell lines. 3b and 3d emerged to be the most potentagents, with IC50 values ranging between 0.98 to 2.45 µM. Target delineation studies followed by secondary anticancer parameters were evaluated for most potent compounds, 3b and 3d. The analysis revealed compounds possess
癌症正在全世界蔓延,是导致死亡的主要原因之一。现有化疗药物的使用经常因副作用而受到限制。因此,研究癌症治疗的新药物至关重要。在此背景下,我们开发了一种电化学方法来合成一系列硫醇连接的嘧啶衍生物( 3a - 3p )并探索其抗癌潜力。针对乳腺癌(MDAMB-231 和 MCF-7)和结直肠(HCT-116)癌细胞系评估了合成化合物的生物学特征。 3b和3d成为最有效的试剂, IC 50值范围在 0.98 至 2.45 µM 之间。对大多数有效化合物3b和3d进行了靶标描绘研究,然后评估了次要抗癌参数。分析显示化合物具有 DNA 嵌入潜力和对人拓扑异构酶 (hTopo1) 的选择性抑制。 DNA 结合研究和基于计算机的分子建模研究进一步证实了该分析,这些研究验证了化合物与 DNA 之间的嵌入结合模式。
