New Drug Delivery Method Could Help Kill Cancer Cells Faster

A team from the Pacific Northwest National Laboratory (PNNL) and Washington State University has found a new accurate and non-toxic treatment that can kill the lung cancer cells at a nanoscale that too at a lower dose. The researchers have made use of tiny tubes to deliver organic molecules known as peptoids to the targeted cells. These molecules could be used to deliver cancer-killing drugs in a target-killing approach. The team head Professor Yuehe Lin found the biologically inspired nanotubes to possibly help track the drug delivered into the cancer cells with the help of fluorescent dyes. The latest technology uses 2 drugs wherein one is used for chemotherapy and the other is used for a painless photodynamic treatment.

Photodynamic therapy is believed to help trigger the release of reactive oxygen species (ROS) that kill cancer cells when exposed to light. The toxicity level of cancer drugs is reduced as lower doses can be used in this dual-drug approach. The tumor cells can be easily located using fluorescent dyes and cancer-targeting molecules. The nanotubes were found to effectively have the chemotherapy drug doxorubicin delivered to the cancer cells for their efficient killing. The damage to healthy cells is reduced to a greater extent. The carbon nanotubes help bring targeted and biocompatible delivery mechanism to reality.

Likewise, researchers in Japan and Indonesia have shown an experimental drug agent to stop cancer cells from growing. The turmeric has been found by the Indonesian researchers to have anti-cancerous properties over a decade back. The compound pentagamavumon-1 (PGV-1) is a molecule found in turmeric that has anti-cancerous effects. The compound is found to inhibit a number of enzymes that play an important role in reactive oxygen activation during specific mechanisms. Thus, the researchers hope that modifications made to PGV-1 can help develop new cancer treatments.
