探索非洲锥虫缩氨基硫脲的结构-活性关系:布氏锥虫布氏,一系列的35缩氨基硫脲(1 - 35)已被合成和表征可以通过1 H NMR,13 C NMR,和FT-IR光谱。使用“ Lilit alamar blue”方法测试所有化合物的杀锥虫活性。考虑到它们的结构,比较了硫半脲的锥虫杀菌能力。该研究结果表明,使用苯乙酮缩氨基硫脲进行(1)作为基本模型,表明:(a)中的亲脂性的取代基的存在对在苯环上的位置,(b)苯环的取代和(c)硫代酰胺官能团的氢被苯基取代,强烈影响锥虫活性。对基本结构(1)的各种修饰允许合成1-(4-氯苯基)亚乙基-4-苯基-硫代氨基脲(34)。该化合物具有3.97μM的锥虫杀灭活性,是该系列中最活跃的。
solution all the complexes exhibit metal-to-ligand charge transfer transitions (MLCT) in the visible region and are emissive at roomtemperature with quantum yield of 0.001–0.005. The crystalstructure of one of the complexes [Ru(4CAP-PTSC)(CO)(AsPh3)2] (4) has been solved by single crystal X-ray crystallography and it indicates the presence of a distorted octahedral geometry in these complexes. All the complexes

Arene ruthenium(II) p-chloroacetophenone phenylthiosemicarbazone complex mediated transfer hydrogenation of ketones
A series of cationic half-sandwich arene ruthenium(II) complexes of general formula [Ru(eta(6)-p-cymene)Cl (L)]Cl have been synthesized from the reaction of [Ru(eta(6)-p-cymene)Cl-2](2) with thiosemicarbazone derivatives (L). Characterization of the complexes were accomplished by analytical and spectral (FT-IR, UV-Vis, H-1 NMR) methods. Single crystal structure determination reveals the presence of a pseudooctahedral three-legged piano stool conformation. All the complexes exhibit a quasi-reversible one electron reduction in the range from -0.75 to -0.85 V. Further, the catalytic activity of the titled complex has been investigated in the transfer hydrogenation of ketones in the presence of isopropanol/NaOH. (C) 2010 Elsevier B.V. All rights reserved.

structures. This study that was done using acetophenone thiosemicarbazone (1) as basic model, showed that: (a) the presence of lipophilic substituents in para position on benzene ring, (b) substitution of benzene ring and (c) substitution of hydrogen of thioamidefunction by a phenyl, strongly influence trypanocidal activity. The various modifications to basic structure (1) allowed the synthesis of 1-(4-chlorophenyl)
