  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.
