This report describes the synthesis of reversed structured 1-O-alkyl-2,3-diacyl-sn-glycerols (DAGEs) possessing a pure saturated even number fatty acid (C6:0-C16:0) at the sn-2 position along with a pure EPA or DHA located at the terminal sn-3 position of the glycerol backbone of chimyl, batyl and selachyl alcohols. These adducts were synthesized by a highly efficient two-step chemoenzymatic process
该报告描述了在sn-2位置沿sn-2位置具有纯饱和偶数脂肪酸(C6:0-C16:0)的反向结构的1-O-烷基-2,3-二酰基-sn-甘油(DAGEs)的合成纯的EPA或DHA位于Chimyl,batyl和selachyl醇的甘油骨架末端sn-3位置。这些加合物是通过高效的两步化学酶促过程合成的,涉及固定化南极假丝酵母脂肪酶,将纯净的作为肟酯活化的EPA和DHA以优异的产率引入对映体纯的Chimyl,batyl和selachyl醇的sn-3末端位置。随后,在DMAP存在下,使用EDAC偶联剂将饱和脂肪酸以非常高至极高的收率(85%-98%)掺入到所得3-单酰基甘油醚(3-MAGE)的其余sn-2位置。在这些过程中未观察到对映体组成的损失。讨论了所得的反向结构化DAGE聚焦库的多种用途,包括在制药领域如何利用此类化合物。
