Four new Glycosyl-NucleoLipid (GNL) analogs featuring either a single fluorocarbon or double hydrocarbon chains were synthesized in good yields from azido thymidine as starting material. Physicochemical studies (surface tension measurements, differential scanning calorimetry) indicate that hydroxybutanamide-based GNLs feature endothermic phase transition temperatures like the previously reported double chain glycerol-based GNLs. The second generation of GNFs featuring a free nucleobase reported here presents a better surface activity (lower glim) compared to the first generation of GNFs.

甘油糖基-核苷酸类似物(GNL),产率良好。物化研究(表面张力测定、差示扫描量热法)表明,基于羟基丁酰胺的GNL的相变温度表现为吸热,与先前报道的基于双链
甘油的GNL类似。本文报道的第二代含有游离核碱基的GNF显示出更好的表面活性(更低的界面张力),相较于第一代GNF。
