| '''STRUCTURE OF THE HSP90 INHIBITOR MACBECIN BOUND TO THE N-TERMINUS OF YEAST HSP90.'''
| |
| | |
| | |
| ==Overview==
| |
| Macbecin compares favorably to geldanamycin as an Hsp90 inhibitor, being more soluble, stable, more potently inhibiting ATPase activity (IC 50 = 2 microM) and binding with higher affinity ( K d = 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.
