Structure-based design of substituted biphenyl ethylene ethers as ligands binding in the hydrophobic pocket of gp41 and blocking the helical bundle formation
摘要:
A series of substituted biphenyl ethylene ether compounds has been designed to target the gp41 N-trimer in order to inhibit formation of the six-helical bundle that represents the end state of gp41-mediated viral fusion. A size exclusion HPLC based helical bundle formation (HBF) assay was developed to evaluate in vitro inhibitory affinity of the inhibitors. The most potent compound 1 had an IC(50) of 31 mu M. The binding of compound 1 to the proposed hydrophobic pocket of gp41 was further validated by site-directed peptide mutagenesis experiments. (C) 2009 Elsevier Ltd. All rights reserved.
