Inside the Hsp90 inhibitors binding mode through induced fit docking

2009

Abstract During the last few decades, the development of new anticancer strategies had to face the instability of many tumors, occurring when the genetic plasticity of cells produces new drug-resistant cancers. It has been shown that a chaperone protein, heat shock protein 90 (Hsp90), is one of the fundamental factors involved in the cell response to stresses, and its role in many biochemical pathways has been demonstrated. Thus, the inhibition of Hsp90 represents a new target of antitumor therapy, since it may influence many specific signaling pathways. The natural antibiotic Geldanamycin is the first Hsp90 inhibitor that has been identified. Nevertheless, more potent and water-soluble sma…
