MIT chemists design nanoparticles that can deliver three cancer drugs at a time.

Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or two chemotherapy drugs, but it has been difficult to design particles that can carry any more than that in a precise ratio.

Now MIT chemists have devised a new way to build such nanoparticles, making it much easier to include three or more different drugs. In a paper published in the Journal of the American Chemical Society, the researchers showed that they could load their particles with three drugs commonly used to treat ovarian cancer.

CANCER KILLER
A drug-delivering nanoparticle with cisplatin core (green) is formed by polymerization of doxorubicin- and camptothecin-derivatized monomers and a cisplatin cross-linker.
The first polymer nanoparticles that carry a defined ratio of three cancer drugs and release them with three independent triggering mechanisms have been developed. The approach could provide a new way of delivering specific amounts of multiple drugs to patients and could help researchers optimize doses of such combination therapies.
The drug delivery nanoparticles were developed by Jeremiah A. Johnson of MIT and coworkers (J. Am. Chem. Soc. 2014, DOI: 10.1021/ja502011g).
