  Inhibition of Glutathione S-Transferase M1 by New Gabosine Analogues Is Essential for Overcoming Cisplatin Resistance in Lung Cancer Cells

  摘要：

  A new class of human GST inhibitors has been identified via rational design approach; we report their discovery, synthesis, inhibitory activity, and synergetic effect in combination with cisplatin against A549 lung cancer cell line. The results of this effort show that the lead 4-O-decyl-gabosine D (24) has optimum synergetic effect in A549 human lung adenocarcinoma epithelial cell and that this activity involves inhibition of glutathione S-transferase M1, apparently consistent with siRNA-mediated knockdown of GSTM1 gene.

  Synthesis of chiral hydroxylated enones as potential anti-tumor agents

  摘要：

  A series of chiral hydroxylated enones were synthesized as COTC ether analogues to investigate the structural features required for optimal and selective anti-tumor activity. The cytotoxicity of the seven COTC ether analogues against WRL-68 normal and HepG2, HL-60 cancer cell lines were measured. C-4 ether analogues with an aliphatic chain substituent were found to be more favorable than their aromatic counterparts. Inversion of the configuration at C-4 in 5e to give 5f only resulted in reduced selectivity towards cancer cells. These results show that 4-O-pentyl-gabosine D (5e) has optimum selectivity and cytotoxicity towards two cancer cell lines. (c) 2012 Elsevier Ltd. All rights reserved.
