Abstact

Information from X-ray crystal structures of Hsp90 inhibitors bound to the human Hsp90 molecular chaperone was used to assist in the design of 3-(5-chloro-2,4-dihydroxyphenyl)-pyrazole-4-carboxamides as novel inhibitors of Hsp90. Accessing an extra interaction with the protein via Phe138 gave a significant increase in binding potency compared to similar analogues that do not make this interaction.
