Scientists at Roche have used computational methods to screen for small molecule kinase inhibitors (SMKIs) that bind to more than one kinase and cause damage to chromosomes. Using a competitive binding assay, they tested the binding affinity of 113 SMKIs against a representative subset of all 290 kinases. They were able to identify kinases that correlate with chromosome damage, "providing a basis for rational drug design away from genotoxicity," they say.
