  New lipoxygenase inhibitory sphingolipids fromChrozophora plicata

  摘要：

  Two new sphingolipids plicatin A [(2S,3S,4R)-2-{[(2R)-2-hydroxyoctdecanoyl]amino}hexaeicosane-1,3,4-triol (1)] and plicatin B [(2S,3S,4R,10E)-2-{[(2R)-2-hydroxyoctdecanoyl]amino}tricont-10-ene-1,3,4-triol (2)], together with 4-hydroxybenzaldehyde, scopoletin, uracil, and dl-threonolactone were isolated from the methanolic extract of the whole plant of Chrozophora plicata. The structures of these compounds were established using 1D (H-1, C-13) and 2D NMR (HMQC, HMBC, and COSY) spectroscopy and mass spectrometry (EI-MS and HR-EI-MS) and in comparison with the reported data in the literature. Compounds 1 and 2 showed inhibitory potential against enzyme lipoxygenase with IC50 values 195.1 and 102.3M, respectively.

  The invention relates to novel compositions of matter which may advantageously be used as lubricants or pressure transfer media or else for functional liquids and lubricant additives. The lubricants according to the invention are the reaction products of an electro-philic addition of linear or branched, aliphatic or aromatic carboxylic acids, carboxylic anhydrides, carbonyl halides or novel neoacids to the double bonds of fatty acids, esters thereof and/or of other fatty acid derivatives and also of synthetic esters. Owing to their increased oxidation resistance compared to the starting materials and also their low toxicity, the novel class of synthetic esters based on oleochemicals may find use in novel environmentally compatible lubricants, pressure transfer systems, functional liquids and lubricant additives.

  本发明涉及一种新型物质组成，可优势地用作润滑剂或压力传递介质，或者用于功能液体和润滑剂添加剂。根据本发明，润滑剂是线性或支链的，脂肪族或芳香族羧酸，羧酸酐，羰基卤化物或新型新酸通过亲电加成反应与脂肪酸，其酯和/或其他脂肪酸衍生物以及合成酯的双键反应生成的产物。由于与起始材料相比具有较高的氧化抵抗性和低毒性，基于油脂化学的新型合成酯类可以用于新型环境兼容的润滑剂、压力传递系统、功能液体和润滑剂添加剂。
