Hitching a ride: Misfiring drugs hit the wrong targets
Sometimes, these side effects can be caused when a drug hits the wrong target, binding to the wrong protein. However, the difficulty of tracking this process means that little research has been carried out. Now, a new study led by scientists at the University of Oxford and published in Nature Chemistry has shown how a series of anti-HIV protein i nhibitor drugs can interfere with the processing of a protein known as prelamin A, essential for maintaining the shape of human cells and directly related to ageing. The researchers used mass spectrometry -- a long-established way of identifying molecules by measuring their mass -- to observe directly the drugs' 'hitchhiking' on the wrong protein. Professor Dame Carol Robinson of Oxford's Department of Chemistry, corresponding author on the paper, said: 'The "hitchhiking" of drugs on incorrect targets is a common problem but isn't much studied, as it can be difficult to observe directly. You have to ...
