| 摘要 |
The present invention relates to sphingolipid derivatives modified by polyethylene glycol which have superior stability and solubility to conventional sphingolipid derivatives and remarkably reduced toxicity, wherein the sphingolipid is selected from the group consisting of phytosphingosine, sphiganine and sphingadiene. The sphingolipid derivatives are effective in stabilizing other active ingredients in the form of liposome compositions, etc. |
