K-Ras is a well-validated cancer target but is considered to be "undruggable" due to the lack of suitable binding pockets. We previously discovered small molecules that bind weakly to K-Ras but wanted to improve their binding affinities by identifying ligands that bind near our initial hits that we could link together ...
