Abstract The synthesis of a new series of triazole-biscoumarin conjugates by using a molecular hybridization approach is described. The newly synthesized compounds 6a – k were evaluated for their in vitro antitubercular activity against active and dormant Mtb H37Ra and anti-oxidant activity against DPPH radical scavenging. Molecular docking simulations for the antitubercular activity showed that the

Abstract In search of new generation of triazole based antifungal agents, synthesis of series of new 1,2,3-triazolyl pyrano[2,3-c]pyrazoles under ultrasonic irradiation using NaHCO3 has been reported. The bioevaluation results indicate that, the compounds 7c, 7d, 7e, 7f, and 7i displayed excellent antifungal activity with lower MIC ≤ 25 µg/mL. Most of the compounds from the series showed potent antioxidant

Abstract An efficient ultrasound-promoted one-pot three-component synthesis of a series of new 1,2,3-triazole-linked tetrahydrobenzo[ b ]pyran derivatives as antifungal and antioxidant agents using NaHCO3 has been described for the first time. The bioassay result indicates that the compounds 7b , 7c , 7i and 7j displayed excellent antifungal activity with lower MIC = 12.5 µg/mL than the reference drug

We describe the synthesis of novel triazole-incorporated diindolylmethanes (DIMs) using a molecular hybridization approach. The in vitro antitubercular activity of the DIMs against Mycobacterium tuberculosis H37Ra (ATCC 25177) was tested in the active and dormant state. Among all the synthesized conjugates, the compounds 6b, 6f, 6l, 6n, 6q, 6r, and 6s displayed good antitubercular activity against
我们描述了使用分子杂交方法合成新型三唑并入的二吲哚甲烷 (DIM)。在活跃和休眠状态下测试了 DIMs 对结核分枝杆菌H37Ra (ATCC 25177)的体外抗结核活性。在所有合成的偶联物中,化合物6b、6f、6l、6n、6q、6r和6s对活性和休眠的Mtb H37Ra菌株均表现出良好的抗结核活性。化合物6l对休眠Mtb表现出良好的抗结核活性H37Ra的IC 50值为1 μg mL -1和IC 90 (MIC)值为3 μg mL -1。化合物6b、6l和6r对活性Mtb H37Ra表现出良好的抗结核活性,IC 50值分别为2.19、1.52和0.22 μg mL -1。化合物6b、6h、6l和6s在 3 μg mL -1时对革兰氏阳性枯草芽孢杆菌菌株表现出超过 70% 的抑制作用. 分子对接研究显示了标题化合物在 DprE1 酶活性位点的结合模式,并有助于阐明抑制分枝杆菌的结构基础。
