Optimizing Natural Products by Biosynthetic Engineering: Discovery of Nonquinone Hsp90 Inhibitors.
J.Med.Chem., 51:5494-, 2008

PubMed Abstract: A biosynthetic medicinal chemistry approach was applied to the optimization of the natural product Hsp90 inhibitor macbecin. By genetic engineering, mutants have been created to produce novel macbecin analogues including a nonquinone compound (5) that has significantly improved binding affinity to Hsp90 (Kd 3 nM vs 240 nM for macbecin) and reduced toxicity (MTD > or = 250 mg/kg). Structural flexibility may contribute to the preorganization of 5 to exist in solution in the Hsp90-bound conformation.
