Synthesis and biological evaluation of bufalin-3-yl nitrogen-containing-carbamate derivatives as anticancer agents
摘要:
A series of bufalin-3-yl nitrogen-containing-carbamate derivatives 3 were designed, synthesized, and evaluated for their proliferation inhibition activities against human cervical epithelial adenocarcinoma (HeLa) cell line. The structure-activity relationships (SARs) of this new series are described in this paper. Cytotoxicity data revealed that the C3 moiety had an important influence on cytotoxic activity. Compound 3i-HCl exhibited significant in vitro antiproliferative activity against the ten tested tumor cell lines, with IC50 values ranging from 0.30 to 1.09 nM. Furthermore, 3i-HCl can significantly inhibit tumor growth by 100% at the dose 2 mg/kg by iv, or 4 mg/kg by ig. (C) 2016 Elsevier Inc. All rights reserved.
