Bioorg Med Chem Lett. 2009 Jun 1;19(11):3128-35. doi: 10.1016/j.bmcl.2009.03.011. Epub 2009 Mar 9.

Abstract

Chloro-oxime derivatives were investigated as novel small molecule chaperone amplifiers. Lead optimization led to the discovery of compounds that displayed potent HSF1 activation activity, significant cytoprotection in MG-132 stress, ER stress and PolyQ stress cell models (EC(50)<10 microM).
