Bicyclo[2.2.2]octanes: Close structural mimics of the nuclear receptor-binding motif of steroid receptor coactivators
摘要:
Nuclear hormone receptor (NR) function relies on association of agonist-bound receptors with steroid receptor coactivator (SRC) proteins through a small pentapeptide motif (LXXLL) of the SRC that binds to a hydrophobic groove on the NR. We have synthesized a series of bicyclo[2.2.2]octanes that are close structural mimics of the two key leucine residues of this SRC sequence as bound in the hydrophobic groove of the estrogen receptor. These bicyclic systems block the NR-SRC interaction with modest potency. (c) 2007 Elsevier Ltd. All rights reserved.
