title: Synthesis and HIV-1 integrase inhibition activity of some N-arylindoles.
abstract: Eight simple N-arylindoles were designed, synthesized and evaluated as human immunodeficiency virus (HIV)-1 integrase inhibitors in vitro for the first time. Among these compounds, 3b, 3e and 3g demonstrated significant anti-HIV-1 integrase activity. Especially 3b showed the highest anti-HIV-1 integrase activity with EC50 value of 7.88 microg/ml and TI value of 24.61. Meantime, some structure-activity relationships were also observed and will provide a new lead for design and discovery of more potent N-arylindoles as HIV-1 integrase inhibitors.
