Molecular Characterisation of Macbecin as an Hsp90 Inhibitor
J.Med.Chem., 51:2853-, 2008

PubMed Abstract: Macbecin compares favorably to geldanamycin as an Hsp90 inhibitor, being more soluble, stable, more potently inhibiting ATPase activity (IC50 = 2 microM) and binding with higher affinity (Kd = 0.24 microM). Structural studies reveal significant differences in their Hsp90 binding characteristics, and macbecin-induced tumor cell growth inhibition is accompanied by characteristic degradation of Hsp90 client proteins. Macbecin significantly reduced tumor growth rates (minimum T/C: 32%) in a DU145 murine xenograft. Macbecin thus represents an attractive lead for further optimization.
