New drug delivery method to attack cancer cells

Sify News has the latest information on the new drug delivery method to attack cancer cells. The "Trojan Hoarse" system seeks out cancer cells, penetrates them, and once inside they release the drug. Cancerous cells will be the only cells affected, leaving healthy ones alive. Scientists believe that this will best work with ovarian, kidney and uterine cancer.

The drug was designed to work by:
attaching an antitumor drug to the polysaccharide by a small fragment of a protein (a peptide), which is digested by the enzymes present in the lysosome. As a result, the anticancer drug is released only in the lysosome, because there are no equivalent enzymes in the blood that can break down this specific peptide.
