  • Title: Purine-scaffold Hsp90 inhibitors.
    Author: Chiosis G, Tao H.
    Journal: IDrugs; 2006 Nov; 9(11):778-82. PubMed ID: 17096299.
    Abstract:
    Heat shock protein 90 (Hsp90) has emerged as an important target, the inhibition of which is aimed at a wide range of cell transformations that lead to malignancy. A clinical evaluation of 17-AAG, the first Hsp90 inhibitor to enter the clinic, revealed evidence of activity for the compound at a manageable level of toxicity. However, clinical results have also demonstrated the limitations of this drug. The identification of novel Hsp90 inhibitor classes with improved structural characteristics and better pharmacological profiles has therefore become a major focus of interest in the field of cancer therapeutics. This feature describes the purine-scaffold class of Hsp90 inhibitors, focusing on research efforts from the discovery stage to the clinical translation of such compounds.
