  Development of chemical probes: Toward the mode of action of a methylene-linked di(aryl acetate) E1

  摘要：

  Analogues of the novel inhibitor of the PI3-K/PKB pathway, 2-[5-(2-chloroethyl)-2-acetoxy-benzyl]-4-(2-chloroethyl)-phenyl acetate (E1), have been prepared and preliminary SAR performed. This established that at least one of the chloroethyl para-substituents could be removed or modified and the ability to inhibit PKB/Akt activation retained. Synthetic methodologies were then developed to methylene-linked aryl acetates for use as molecular probes to identify the target of compound E1. (C) 2010 Elsevier Ltd. All rights reserved.
