was synthesized by click chemistry in the presence of sodium ascorbate and copper(II) sulfate pentahydrate in 81–94% yield. Various biological properties of the synthesized compounds including DNA binding/cleavage, antioxidant, antibacterial and antifungal properties were evaluated. The DNA binding study was performed using dsDNA and G-quadruplex DNA. All of the compounds showed fluorescence increase
一系列新颖的1,4-萘醌-三唑杂化物N-(3-amino-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-2-(4-R-1 H -1,2在抗坏血酸钠和五水合硫酸铜(II)的存在下,通过点击化学合成了3-3-三唑-1-基)乙酰胺,收率为81-94%。评价了合成化合物的各种生物学特性,包括DNA结合/裂解,抗氧化剂,抗菌和抗真菌特性。使用dsDNA和G-四链体DNA进行DNA结合研究。无论结构如何,所有化合物在DNA存在下均显示荧光增强。与双链或G-四链体DNA孵育后,检测到5f和5g荧光强度分别提高了2.9和2.5倍, 分别。在dsDNA和G-四链体结构上进行的对接研究表明,化合物的相互作用方式集中在凹槽周围。所有这些化合物均显示出优异的DNA切割活性,并且5e几乎降解了质粒DNA。在200 mg / L的条件下5d可获得最高的自由基清除活性,为89.9%。然而,在200mg
