| titleOfInvention | A kind of nanoparticle formed based on host-guest interaction and its preparation method and purposes |
| abstract | A kind of poly epsilon caprolactone lactone using an end group as adamantane or poly- D, L lactides are hydrophobic core, the beta cyclodextrin of more PVP macromolecular chains passes through the nano-particle that adamantane is formed with beta cyclodextrin host-guest interaction as hydrophilic segment using hydroxyl modified on multiple 6 C of glucose.It is characterized in that：Its surface is hydrophilic PVP, and inside is hydrophobic poly epsilon caprolactone lactone or poly- D, L lactide, and two parts are connected by the host-guest interaction of adamantane and beta cyclodextrin.It is 2000~10000g/mol to be connected to the poly epsilon caprolactone lactone of adamantane or poly- D, L lactide molecular weight, and beta cyclodextrin can modify more PVPs, and the molecular weight of every PVP is 1000~10000g/mol.The particle diameter distribution of nanoparticle is 40~200nm.The nanoparticle of the present invention has good bio-compatibility and stability, can be used as pharmaceutical carrier, have slow releasing function, the invention discloses its way and purposes. |
