    Glucosamine-glycerophospholipids That Activate Cell-Matrix Adhesion and Migration
    摘要:
    Two new analogues derived from the platelet activating factor (PAF), containing glucosamine instead of the acetyl group, were synthesized, and their effect on the human keratinocyte cell line HaCaT was evaluated with respect to cytotoxicity, proliferation, adhesion, and migration. Starting with (R)-1,2-isopropylideneglycerol (3), the glycosylation acceptor 1-O-octadecyl-3-O-tert-butyldimethylsilyl-sn-glycerol (6) was synthesized in three steps. Glycosylation of 6 with the already known O-(3,4,6-tri-O-acetyl-2-deoxy-2-dimethylmaleimido-beta-D-glycopyranosyl)trichloracetimidate gave 1-O-octadecyl-2-O-(3',4',6'-tri-O-acetyl-2'-deoxy-2'-dimethylmaleimido-beta-D-glucopyranosyl)-3-O-tert-butyldimethylsilyl-sn-glycerol (7). After removing the (tert-butyldimethyl)silyl (TBDMS) group with FeCl3 center dot 6H(2)O, phosphoryl choline was introduced, yielding [1-O-octadecyl-2-O-(2'-deoxy-2'-dimethylmaleimido-beta-D-glucopyranosyl)-sn-glycero(3)]phosphorylcholine (2) (glucosimide-PAF). pH controlled cleavage of the amino protection group gave [1-O-octadecyl-2-O-(2'-deoxy-2'-amino-beta-D-glucopyranosyl)-sn-glycero(3)]phosphorylcholine hydrochloride (1) (glucosamine-PAF). 2 inhibited proliferation of HaCaT cells by 26% at nontoxic concentrations, while 1 increased the proliferation rate by 30% at low concentrations. At higher concentrations, both compounds showed cytotoxic properties with LD50 = 30 mu mol/L (1) and LD50 = 5-6 mu mol/L (2). Both 1 and 2 were potent promoters of cell adhesion and migration of HaCaT cells.

    天然烷基甘油的对映体合成及其抗菌和抗生物膜活性
    摘要:
    摘要 烷基甘油(AKGs)是通过烷基链长和不饱和度而变化的生物活性的天然化合物,它们的绝对构型为2小号。三个 AKGs ( 5l – 5n ) 以对映体纯的形式合成,并首次与其他 12 个已知和天然存在的 AKGs ( 5a – 5k , 5o )一起表征。它们的结构是使用1 H 和13 C APT NMR 与 2D-NMR、ESI-MS 或 HRESI-MS 和旋光数据建立的,并测试了它们的抗菌和抗生物膜活性。AKG 5a – 5m和5o对五种临床分离株和铜绿假单胞菌ATCC 15442显示出活性,MIC 值在 15–125 µg/mL 范围内。此外,在 MIC 的一半时,大多数 AKG 减少了 23%–99% 范围内的金黄色葡萄球菌生物膜形成和14%–64% 范围内的铜绿假单胞菌ATCC 15442 生物膜形成。在这项工作中评估的 AKG 的抗生物膜活性以前没有被研究过。

    A highly efficient two-step chemoenzymatic synthesis of enantiopure structured ether lipids of the 1-O-alkyl-2,3-diacyl-sn-glycerol type has been developed. Chimyl, batyl and selachyl alcohols possessing pure saturated fatty acid (SFA) attached to the sn-3 position and pure EPA and DHA attached to the sn-2 position were obtained under full regiocontrol. This was offered by mild conditions and a highly
