Tumour-targeting platinum-based cancer drugs (gold nanoparticles)

Description:
Reference Number: 1771

Background

Cancer is believed to account for 12% of deaths worldwide. This incidence is increasing in Western countries, as the average age of the population increases.
The University of Strathclyde has been undertaking research into novel delivery systems for the latest drug treatments. Cisplatin, for example, is used to treat a wide variety of human cancers but many cancer cells have, or soon acquire, resistance to it. In addition to the acquired resistance problem, there are also severe side effects associated with these drugs; due mostly to their attack on all rapidly-dividing cells within the body.

Technology

A research team at the University of Strathclyde has successfully developed a method for attaching anticancer drug molecules and targeting groups to metal nanoparticles to provide significant therapeutic benefits. In Vitro studies using Cisplatin nanoparticles demonstrated significantly better cytotoxicity than with Cisplatin alone and an unusual ability to penetrate the cell nucleus – offering enormous improvement over existing anticancer treatments.

Key Benefits

  • Improved targeting of cancer cells, leading to reduced chemotherapy side effects
  • Better targeting provides higher cancer cell kill rates
  • This, in turn, decreases the tendency to develop resistance
  • In cells which have already acquired resistance, enhanced targeting helps to overcome this

Markets and Applications

This approach allows a very much larger number of drug molecules to attach to each nanoparticle, resulting in significantly higher concentrations of chemotherapy molecules -and potentially the treatment of diseases other than Cancer. This would allow for a faster treatment cycle and use by patients with more advanced disease.
Nanoparticle-based delivery also enables administration of these drugs to occur via a wide range of approaches -from injection to inhalation. In addition to use with human patients, the technology lends itself to veterinary applications.
