A Series of Benzylidenes Linked to Hydrazine‐1‐carbothioamide as Tyrosinase Inhibitors: Synthesis, Biological Evaluation and Structure−Activity Relationship
and enzymatic browning of vegetables and fruits. In the present article, 12 small molecules of benzylidene-hydrazinecarbothioamide were designed, synthesized and evaluated for their anti-tyrosinase activities followed by molecular docking and pharmacophore-based screening. Among synthesized thiosemicarbazone derivatives, 3d is the strongest inhibitor of mushroom tyrosinase with IC 50 of 0.05 µM which

A series of hydrazine-1-carbothioamides derivatives (3a-3j) were synthesized and analyzed for inhibitory potential towards bovine carbonicanhydrase II (b-CA II) and 15-lipoxygenase (15-LOX). Interestingly, four derivatives, 3b, 3d, 3g, and 3j, were found to be selective inhibitors of CA II, while other derivatives exhibited CA II and 15-LOX inhibition. In silico studies of the most potent inhibitors
合成了一系列肼-1-硫代甲酰胺衍生物 (3a-3j),并分析了对牛碳酸酐酶 II (b-CA II) 和 15-脂氧合酶 (15-LOX) 的抑制潜力。有趣的是,发现四种衍生物 3b、3d、3g 和 3j 是 CA II 的选择性抑制剂,而其他衍生物则表现出 CA II 和 15-LOX 抑制作用。对最有效的 b-CA II 和 15-LOX 抑制剂进行了计算机模拟研究,以发现化合物在其活性位点的可能结合模式。此外,MD模拟结果证实这些配体与两个靶标稳定结合,而结合能进一步证实了3h化合物的抑制作用。由于这些化合物可能与特定疾病有关,

substituted thiazole derivatives were designed, synthesized and characterized by FTIR, 1H, &13C NMR spectroscopy. The derivatives were then evaluated for their potential to inhibit 15-LOX and bovine carbonic anhydrase II (bCA II). Most of these compounds showed excellent inhibitory potential for 15-LOX with an IC50 of 0.12 ± 0.002 to 0.69 ± 0.5 μM and showed moderate inhibition potency for bCA II with compound
