  • Optically Active Monoacylglycerols: Synthesis and Assessment of Purity
    作者:Chao-Yuan Chen、Wei-Bo Han、Hui-Jun Chen、Yikang Wu、Po Gao

    日期:2013.7
    Despite their simple structures, synthesis of 1(or 3)-acyl-sn-glycerols remains a challenge that cannot be ignored because of facile acyl migrations, which not only complicate the synthesis but also make direct GC or HPLC analysis unfeasible. Assessment of the optical purity of monoacylglycerols has, to date, relied almost exclusively on specific rotation data, which are small in value and thus insensitive
    尽管结构简单,但 1(或 3)-酰基-sn-甘油的合成仍然是一个不容忽视的挑战,因为酰基迁移容易,这不仅使合成复杂化,而且使直接 GC 或 HPLC 分析不可行。迄今为止,单酰基甘油光学纯度的评估几乎完全依赖于比旋光度数据,这些数据价值小,因此对杂质不敏感。现在,已经找到了一种“放大”小比旋光度的简单方法,以及测量 1,2- 和 1,3-酰基迁移的实用方法,这些方法为 Mori 的 NMR 分析提供了一种方便且直接的替代方法。莫舍酯。借助这些方法,在合成两种天然单酰基甘油的过程中,研究了一系列脱丙酮的条件。
  • The Synthesis of Some Esters of Glycerol With Special Attention to the Problem of Acyl Migration

    Various triglycerides have been prepared by the acylation of either cis-1,3-O-benzylideneglycerol or 2,3-O-isopropylideneglycerol, followed by removal of the protecting group and acylation of the resultant diol. Alternatively, acylation of dihydroxyacetone, reduction of the intermediate ketone with sodium cyanoborohydride (pH 4) and acylation of the resultant alcohol also provide triglycerides in good yields. In some of these esters of glycerol, 13C n.m.r . spectroscopy (125.7 MHz) was used to monitor potential acyl migration. Finally, 2-halopyridinium salts were investigated as an alternative to the normal dicyclohexylcarbodiimide/dimethylaminopyridine couple for glycerol esterification.

    通过对顺式-1,3-O-亚苄基甘油或 2,3-O-亚异丙基甘油进行酰化,然后去除保护基团并对生成的二元醇进行酰化,可以制备出各种甘油三酯。另外,二羟基丙酮的酰化、中间酮与氰基硼氢化钠(pH 值为 4)的还原以及由此产生的醇的酰化也能以良好的收率提供甘油三酯。在其中一些甘油酯中,13C n.m.r .光谱(125.7 MHz)被用来监测潜在的酰基迁移。最后,研究人员还研究了 2-卤代吡啶鎓盐,以替代用于甘油酯化的普通二环己基碳二亚胺/二甲基氨基吡啶偶联物。

  • Biochemical characterization of the PHARC-associated serine hydrolase ABHD12 reveals its preference for very-long-chain lipids
    作者:Alaumy Joshi、Minhaj Shaikh、Shubham Singh、Abinaya Rajendran、Amol Mhetre、Siddhesh S. Kamat

    Polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract (PHARC) is a rare genetic human neurological disorder caused by null mutations to the Abhd12 gene, which encodes the integral membrane serine hydrolase enzyme ABHD12. Although the role that ABHD12 plays in PHARC is understood, the thorough biochemical characterization of ABHD12 is lacking. Here, we report the facile synthesis of mono-1-(fatty)acyl-glycerol lipids of varying chain lengths and unsaturation and use this lipid substrate library to biochemically characterize recombinant mammalian ABHD12. The substrate profiling study for ABHD12 suggested that this enzyme requires glycosylation for optimal activity and that it has a strong preference for very-long-chain lipid substrates. We further validated this substrate profile against brain membrane lysates generated from WT and ABHD12 knockout mice. Finally, using cellular organelle fractionation and immunofluorescence assays, we show that mammalian ABHD12 is enriched on the endoplasmic reticulum membrane, where most of the very-long-chain fatty acids are biosynthesized in cells. Taken together, our findings provide a biochemical explanation for why very-long-chain lipids (such as lysophosphatidylserine lipids) accumulate in the brains of ABHD12 knockout mice, which is a murine model of PHARC.
