    Sialic acid/polysialic acid in the drug delivery systems In the history of drug delivery systems (DDS), carrier and drug molecules PEGylated (PEGylation) technology is regarded as a milestone. PEGylation nanoparticles can effectively reduce the macrophage uptake in vitro , prolong the circulation half-life in vivo and decrease the accumulation ...Author: Ting Zhang, Zhennan She, Zhenjun Huang, Jing Li, Xiang Luo, Yihui Deng

Polysialic acids: potential in drug delivery - ScienceDirect

    https://www.sciencedirect.com/science/article/pii/0014579393811772
    A number of bacterial polysialic acids were injected intravenously into mice. Half-lives (up to 40 h) in the blood circulation were dependent on the polysialic acid used, increased by deacylation of their phospholipid moiety, decreased with shorter chain derivatives and appeared to be dose independent.Author: G. Gregoriadis, B. McCormack, Z. Wang, R. Lifely

Polysialic acids: potential in drug delivery.

    https://www.ncbi.nlm.nih.gov/pubmed/8422917
    Jan 11, 1993 · Half-lives (up to 40 h) in the blood circulation were dependent on the polysialic acid used, increased by deacylation of their phospholipid moiety, decreased with shorter chain derivatives and appeared to be dose independent. A model drug (fluorescein) covalently coupled to a polysialic acid was found to assume the half-life of its carrier.Author: G. Gregoriadis, B. McCormack, Z. Wang, R. Lifely
