Identification and initial SAR of silybin: An Hsp90 inhibitor
摘要:
Through Hsp90-dependent firefly luciferase refolding and Hsp90-dependent heme-regulated eIF2 alpha kinase (HRI) activation assays, silybin was identified as a novel Hsp90 inhibitor. Subsequently, a library of silybin analogues was designed, synthesized and evaluated. Initial SAR studies identified the essential, non-essential and detrimental functionalities on silybin that contribute to Hsp90 inhibition.[GRAPHICS]. (C) 2011 Elsevier Ltd. All rights reserved.
