The syntheses of hydrazonederivatives with thiazole and triazole rings were described. The target compounds 7a-j and 8a-g with the hydrazine based structure containing thiazole and triazole rings were synthesized respectively through the reactions of α-bromomethylpyrazole ketone 3 with arylethanone thiosemicarbazones 5a-j and the reactions of pyrazol thiosemicarbazone 4 with α-bromomethyl aryl ketones
描述了derivatives衍生物与噻唑和三唑环的合成。分别通过αα-溴甲基吡唑酮3与芳酮硫代半氨基咔唑酮5a-j的反应和吡唑硫代半碳a酮4与α-β的反应,分别合成具有噻唑和三唑环的肼基结构的目标化合物7a-j和8a-g。在没有催化剂的回流条件下,溴甲基芳基酮6a-g。此外,使用一锅法开发了一种生态友好的合成化合物8a-g的简便方法。通过使用H 2 O 2诱导的具有氧化损伤的PC 12细胞,测试了目标化合物的初步生物活性。

A series of 2-(1-phenylalkylidene)hydrazinecarbothioamides 2, 2-(1-phenylalkyl)hydrazinecarbothioamides 3, 2-(3,4-dihydronaphthalen-1(2H)-ylidene)hydrazinecarbothioamide (4), and 2-(1-(thiophen-2-yl)ethylidene)hydrazinecarbothioamide (5) were synthesized for their melanogenesis inhibition in melanoma B16 cells. The SAR of these ketonethiosemicarbazones revealed that the benzylidene hydrogen in ald

Abstract In an attempt to synthesize Ru(II)-dmso-thiosemicarbazone complexes, a series of carbonyl compounds were selected to condense with thiosemicarbazide in ethanol in order to get the respective thiosemicarbazone ligand as the first step. All the selected carbonyl compounds yielded the expected thiosemicarbazone ligand, but the product obtained by the reaction of benzaldehyde with thiosemicarbazide

high purities. Antioxidantactivity of products was evaluated using DPPH (2,2-diphenyl-2-picrylhydrazyl) and ABTS 2,2-azinobis(3-ethylbenzothiazoline-sulfonate) assays. Products showed higher antioxidantactivity using the ABTS method. Compounds 5c and 5g showed lower IC50 values compared with ascorbic acid as a standard. Compounds 5a–5h possessed moderate to high antioxidantactivity by both methods
