4-(3-Nitrophenyl)thiazol-2-ylhydrazone derivatives as antioxidants and selective hMAO-B inhibitors: synthesis, biological activity and computational analysis
Abstract A new series of 4-(3-nitrophenyl)thiazol-2-ylhydrazone derivatives were designed, synthesised, and evaluated to assess their inhibitory effect on the human monoamineoxidase (hMAO) A and B isoforms. Different (un)substituted (hetero)aromatic substituents were linked to N1 of the hydrazone in order to establish robust structure–activity relationships. The results of the biological testing demonstrated

series of PdII complexesderivedfromthiosemicarbazone has been synthesized. The synthesized PdII complexes have been characterized on the basis of elemental analyses, FT-IR, ¹H- and ¹³C-NMR, UV/VIS, and thermal studies. A square-planar geometry has been assigned around PdII ions on the basis of results obtained from UV/VIS studies. The thiosemicarbazone ligand and its PdII complexes have been screened
Platinum(II) and palladium(II) complexes [ML2] have been isolated from reaction of K2PtCl4 or K2PdCl4 and ligands (L) derivedfromthiosemicarbazones. The complexes were characterized by elemental analysis, Raman, IR, and NMR spectroscopy. In addition, quantum mechanical calculations were used to predict their structures and spectroscopic properties. For the first time, theoretical calculations using

synthesized followed by complexation with various Pd(II) and Pt(II) metal precursors. The ligands (E)-1-((thiophen-2-yl)methylene)thiosemicarbazide (L1), (E)-1-((4-bromothiophen-2-yl)methylene)thiosemicarbazide (L2), and (E)-1-((5-bromo thiophen-2-yl)methylene)thiosemicarbazide (L3) were synthesized by condensation reactions and obtained in good yields. Complexation of L1 and L2 with Pd(cod)Cl2 gave C1 (C6H7Cl2N3PdS2)

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,
