Synthesis and biological evaluation of novel antiviral agents as protein-protein interaction inhibitors

摘要

In continuation of our research efforts toward the identification and optimization for novel inhibitors of interaction between human immunodeficiency virus type 1 integrase and cellular cofactor LEDGF/p75, we designed and synthesized a new series of 4-benzylindole derivatives. Most of the title compounds proved to be able to block this protein-protein interaction (PPI), with a percentage ranging from 30% to 90% at 100 mu M. The most promising derivative was compound 10b showing IC50 value of 6.41 mu M. The main structure-activity relationships (SAR) are discussed and rationalized by docking studies.
