Semicarbazones and thiosemicarbazones, XIII: Study of the hydrolysis of coordinated thiosemicarbazones
摘要:
The hydrolysis of coordinated thiosemicarbazones was studied. It was found that the nickel(II) ion promotes the reaction. Steric and electronic influences were found. The hydrolysis of ATSC in the trigonal bipyramid compounds [M(ATSC)2Cl]Cl[M = Fe(II), Co(II), Ni(II)], is higher with the Ni(II) complex, the compound with the shorter M-N distance.
合成了一系列的1-(1-芳基亚乙基)硫代氨基脲化合物及其类似物,并通过1 H NMR,MS进行了表征。通过与4-甲氧基肉桂酸和熊果苷相比,基于酪氨酸酶对L-DOPA的氧化的催化能力的测定,研究了它们的酪氨酸酶抑制活性。结果表明:(1)所有合成的化合物均对酪氨酸酶具有明显的抑制作用;(2)对于这些化合物,与酪氨酸酶中心相互作用的主要活性部分是硫代氨基脲基。(3)抑制活性与硫代氨基脲部分和连接在芳环上的基团密切相关。

In this work, we have synthesized a series of 2‐thiazolylhydrazone derivatives (1–27) and investigated their biological activities as tyrosinase inhibitors and antioxidants. Some compounds showed potent tyrosinase inhibitory activities and 4‐(2‐(2‐(1‐(4‐Aminophenyl)ethylidene)‐hydrazinyl)thiazol‐4‐yl) phenol (26) showed more potent inhibitory effect than the standard tyrosinase inhibitor kojic acid

infection. This led us to research for new agents against Toxoplasma gondii. Recent findings have shown the potent biological activity of 4-thiazolidinones. We proposed to design and synthesize a new series of 2-hydrazono-4-thiazolidinones derivatives to evaluate the in vitro growth inhibition effect on T. gondii. The growth rates of T. gondii tachyzoites in Human Foreskin Fibroblast (HFF) cell culture were
