The discovery and optimization of potency and metabolic stability of a novel class of dihyroxyphenylisoindoline amides as Hsp90 inhibitors are presented. Optimization of a screening hit using structure-based design and modification of log D and chemical structural features led to the identification of a class of orally bioavailable non-quinone-containing Hsp90 inhibitors. This class is exemplified by 14 and 15, which possess improved cell potency and pharmacokinetic profiles compared with the original screening hit.
