Anti-malarial drug can make cancer chemotherapy more effective
Source: medicalxpress.com Author: Emma McKinney, University of Birmingham Scientists at the University of Birmingham have found an anti-malarial drug was effective in treating head and neck cancer in mice. The drug quinacrine was used extensively to prevent and treat malaria in soldiers fighting in mosquito-ridden areas during World War Two. It is similar to the quinine that makes tonic water glow, has minimal side-effects, and is now used for treating parasite infections and other conditions. Each year around 11,900 people are diagnosed with head and neck cancer in the UK. Current treatment relies heavily on debilitating surgery and toxic chemotherapy, but despite this, it has a poor outcome with three to seven in 10 people surviving their disease for five years or more. The drug, quinacrine, was tested through a number of methods, including on cell cultures, in tumour biopsies from patients with head and neck cancer, and in mice. The research results, published in Oncotarget, show that in mice quinacrine can make standard chemotherapy more effective—suggesting a lower dose may be used, reducing toxic side effects. The results also showed the drug to be effective at reducing the growth of cancer cells grown in the lab, and in tumors. Significantly, the research in mice showed a combination therapy of quinacrine and chemotherapy, and so allowed for the chemotherapy dose to be halved while still maintaining the same impairment of tumor growth.
