This paper reports the synthesis of methoxy-and bromo-indirubins, and their antiproliferative activities in human neuroblastoma. Among 20 compounds, 5'-methoxyindirubin induced cell death in human neuroblastoma cells (IMR-32, SK-N-SH and NB-39) without inhibiting normal cells (NHDF and HUVEC). Typical morphologic features of apoptosis were observed in 50-methoxyindirubin-treated cells by Hoechst 33342 staining. Additional studies by flow cytometry support apoptosis induction. These data suggest that 5'-methoxyindirubin might be an effective drug for treatment of neuroblastoma. (C) 2011 Elsevier Ltd. All rights reserved.
