Second site leads were also identified which bound to HSP90 in two distinct conformations, an 'open' and 'closed' form. Intriguingly, linked fragment approaches targeting both of these conformations were successful in producing novel, micromolar inhibitors. Overall, this study shows that, with only a few fragment hits, multiple lead series can be generated for HSP90 due to the inherent flexibility of the active site.
