| 中文摘要: |
| 以1,2-二硬脂酸甘油酯为原料,与三氯氧磷及乙醇胺反应合成1,2-二硬脂酰甘油磷酰乙醇胺(DSPE)；再以聚乙二醇2000(PEG2000)为原料,通过磺酰化、叠氮化反应合成叠氮基聚乙二醇2000(N<sub>3</sub>-PEG2000)；DSPE与N<sub>3</sub>-PEG2000在N,N-羰基二咪唑(CDI)作用下生成叠氮基聚乙二醇2000-1,2-二硬脂酰甘油磷酰乙醇胺(N<sub>3</sub>-PEG2000-DSPE)；最后通过催化氢化制备氨基聚乙二醇2000-1,2-二硬脂酰甘油磷酰乙醇胺(NH<sub>2</sub>-PEG2000-DSPE),其结构经过IR,MS及<sub>1</sub>H NMR等确证。 |
| 英文摘要: |
| DSPE was synthesized by reactions with Glycerol-1,2-distearate, Phosphorusoxychloride and 2-Aminoethanol as raw materials. N<sub>3</sub>-PEG2000 was achieved by an efficient two step process from readily available PEG2000. Subsequently, N<sub>3</sub>-PEG2000-DSPE was obtained by linking DSPE to N<sub>3</sub>-PEG2000 via CDI. Finally, catalytic hydrogenation of the azidoSgroup yielded the target compound NH<sub>2</sub>-PEG2000-DSPE, which was characterized by IR analysis, <sub>1</sub>H NMR spectroscopy, mass spectrometry. |
