Synthesis and biological evaluation of sulforaphane derivatives as potential antitumor agents
摘要:
A series of sulforaphane derivatives were synthesized and evaluated in vitro for their cytotoxicity against five cancer cell lines (HepG2, A549, MCF-7, HCT-116 and SH-SY5Y). The pharmacological results showed that many of the derivatives displayed more potent cytotoxicity than sulforaphane (SFN). Furthermore, SFN and derivative 85 could induce cell cycle arrest at S or G2/M phase and cell apoptosis. SFN and 85 exhibited time- and dose-dependent activation on Nrf2 transcription factor, and 85 acted as a more potent Nrf2 inducer than SFN. (C) 2013 Elsevier Masson SAS. All rights reserved.
