values were either under the 10 μg/ml MIC limit recognized to delimit efficient antimicrobials or were comparable to/lower than those of the used positive controls (tetracycline/nystatin). The most susceptible organism was found to be Staphylococcus aureus with MIC values even reaching 0.001 μg/ml. The presence of -CH(OH)(CH(2))(n)S- and -CH(=NOH)(CH(2))(n)S- (n=1 or 2) structural fragments seems to be essential
一个小型图书馆,包含四个不同系列的新二茂铁衍生物,2-(烷基硫烷基)-1-二茂铁基乙烷-1-醇,3-(烷基硫烷基)-1-二茂铁基丙烷-1-醇,(E)-和(Z)-2 -(烷基硫烷基)-1-二茂铁基乙烷-1-酮肟,和(E)-和(Z)-3-(烷基硫烷基)-1-二茂铁基丙烷-1-酮肟(总共36种化合物)从二茂铁开始合成和相应的硫烷基酸。对所有化合物进行光谱分析(IR和NMR)并进行电化学表征。通常,发现所获得的化合物对被测微生物(六种常见人类病原体)表现出非常强的抗菌活性(肉汤微稀释法)。对于大多数测试化合物,确定的MIC值在10μg/ ml MIC限度以下,该限度被认为可以界定有效的抗菌药物,或者与使用的阳性对照(四环素/制霉菌素)相当或更低。发现最易感的生物是金黄色葡萄球菌,MIC值甚至达到0.001μg/ ml。-CH(OH)(CH(2))(n)S-和-CH(= NOH)(CH(2))(n)S-(n

facile microwave-assisted synthesis has been developed for the preparation of unsymmetrical sulfide derivatives from 3-mercaptopropionic acid and a wide variety of alkyl, allyl or aryl chlorides or bromides. The synthesis performed in ethanol at 80 or 120 °C using sodium hydroxide as a base, selectively without an offensive smell, generates 3-(alkylthio)propionic acids in good yields. Effects of reaction

Six DMSP lyases were investigated for their potential to cleave synthetic DMSOP analogs with longer alkyl chains into sulfoxides and acrylate. The pH dependency and enzyme kinetics of these reactions were determined, showing efficient transformation by four of the studied DMSP lyases.

Several known and eight new sulfur containing acylferrocenes of the general formula FcCO(CH2)(n)SR (where Fc = ferrocenyl, n = 1 or 2 and R = alkyl, 4-bromobenzyl or 2,6-dichlorobenzyl group) were synthesized in order to test their in vitro antimicrobial activity against 11 bacterial and three fungal/yeast strains. It has been shown that only four of the 14 ketones are completely inactive at the tested dose, while the activities of the other ones were noteworthy. All new compounds were well characterized by IR and NMR spectral data, and their electrochemical properties were investigated by cyclic voltammetry. The X-ray crystal structures of two representative ketones are also presented. (C) 2010 Elsevier Ltd. All rights reserved.
