Hooking up! Hsp90 is a molecular chaperone involved in the stabilisation of numerous client proteins including those involved in oncogenic transformations. Through a high-throughput biochemical fragment screen, we have identified novel fragment inhibitors of Hsp90. Two fragment hits were combined to give a dual-fragment Hsp90 complex, and the following successful fragment-linking resulted in a 1000-fold improvement in activity. (Chemical Equation Presented).
