Tumor-like spheres help scientists discover smarter cancer drugs

Scientists are reporting an innovative new method to screen for potential cancer drugs. The technique makes use of tiny, three-dimensional ball-like aggregates of cells called spheroids. These structures can be used to interrogate hundreds or even thousands of compounds rapidly using a technique called high throughput screening.

Cancer drug observed at work

Using a Raman microscope, researchers have studied at which targets the cancer drug Neratinib binds in cells and how its chemical structure changes. Compared with other techniques, this method offers a considerable advantage, as it is not necessary to apply a label to the drug that would indicate its distribution indirectly; rather, the drug itself can be monitored.
