Synthesis and biological evaluation of novel β-carboline derivatives as Tat–TAR interaction inhibitors
摘要:
Four new beta-carboline derivatives were synthesized bearing guanidinium group or amino group-terminated side chain targeting the TAR element. Compounds 5 and 6 with terminal guanidinium group showed inhibitory activities on Tat-TAR interaction as well as to HIV-1 in MT4 cells. Furthermore, capillary electrophoresis assay implied that compound 6 could not only bind to TAR but also hinder the Tat-TAR interaction. (C) 2004 Elsevier Ltd. All rights reserved.
