Fragment‐based Identification of Hsp90 Inhibitors

Heat shock protein 90 (Hsp90) plays a key role in stress response and protection of the cell against the effects of mutation. Herein we report the identification of an Hsp90 inhibitor identified by fragment screening using a high‐concentration biochemical assay, as well as its optimisation by in silico searching coupled with a structure‐based drug design (SBDD) approach.
