Synthesis and evaluation of Hsp90 inhibitors that contain the 1,4-naphthoquinone scaffold
摘要:
High-throughput screening of a library of diverse molecules has identified the 1,4-naphthoquinone scaffold as a new class of Hsp90 inhibitors. The synthesis and evaluation of a rationally-designed series of analogues containing the naphthoquinone core scaffold has provided key structure-activity relationships for these compounds. The most active inhibitors exhibited potent in vitro activity with low micromolar IC50 values in anti-proliferation and Her2 degradation assays. In addition, 3g, 12, and 13a induced the degradation of oncogenic Hsp90 client proteins, a hallmark of Hsp90 inhibition. The identification of these naphthoquinones as Hsp90 inhibitors provides a new scaffold upon which improved Hsp90 inhibitors can be developed. (C) 2008 Elsevier Ltd. All rights reserved.
