Title:
HEPARIN NANO DRUG CARRIER SYSTEM FOR LOADING AMINO ANTI-TUMOR DRUG, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/203959
Kind Code:
A1
Abstract:
Disclosed in the present invention is a heparin nano drug carrier system for loading an amino anti-tumor drug. The drug carrier system is a conjugate for loading the amino anti-tumor drug on a PEGylated heparin molecule. A natural polysaccharide heparin that is biodegradable and has good compatibility and high availability is used as a drug carrier, and, by means of combining PEG modification and the amino anti-tumor drug, as compared with free drugs, nanoparticles have a significantly enhanced anti-tumor therapeutic index and biological safety in in-vivo therapy.
