• Associated context:

  Importantly, however, the crystal structure of compound 6 bound to Chk1 con-  firmed that the methyl group was added toward the targeted pocket (Figure 3). The associated crystallographic electron density could be interpreted such that only the R stereoisomer was bound to Chk1. Compound  7 was made by building on compound 6, with the intention that the added hydroxyl group may hydrogen bond to Ser147.
