favors the synthesis of dual-PEGylated DA derivatives, whereas large degree of polymerization is good for the preparation of mono-PEGylated DA derivatives. As compared to the prototype compound DA, the PEGylated DA derivatives show enhanced water solubility which is beneficial to drug's bioavailability. Preliminary study finds that the PEGylated DA derivatives exhibit better anti-bacterial activity than
已经合成了一类具有低聚乙二醇(PEG)取代基的14-脱氧-11,12-二氢-穿心莲内酯(DA)衍生物。发现PEG的小聚合度有利于双PEG化的DA衍生物的合成,而大的聚合度对于单PEG化的DA衍生物的制备是有利的。与原型化合物DA相比,PEG化的DA衍生物显示出增强的水溶性,这对药物的生物利用度有利。初步研究发现,聚乙二醇化DA衍生物表现出比更好的抗菌活性DA。
