    摘要: Drug delivery to the cancer cells during its treatment is challenging. Most of the cancer drug cannot reach to the target because of its complex membrane physiology, drug resistance, and mutability. Establishment of a potential target molecule or domain on the cancer cell is the rate limiting step for the successful drug delivery. Cancer is characterized by abnormal energy metabolism shaped by nutrient deprivation that malignant cells experience during various stages of tumor development. This patent demonstrated a new method of establishing a new target domain that could have enormous importance for the drug delivery during cancer treatment. The inventors showed how nutrient-deprived cancer cells become involved in robust membrane glycan display while treating with nucleotide sugar such as sialic acid and that glycosylated membrane domain become a target domain of cancer cell treatment. The inventor showed how to use the lectin, by making a compound with nanomagnetic particles in the treatment of cancer cells. Using the nanomagnetic lectin inventor established an innovative method to treat the cancer cells and showed how prostate cancer cells in the xenograft can be regressed using the technology in the non-limited Example-1 section. In conclusion, nucleotide sugar supplement to nutrient deprived cancer cells enforce them to robust membrane glycan display which could be a novel tool for the successful drug delivery during cancer cell treatment.
