  Synthesis and Anticancer Mechanism Investigation of Dual Hsp27 and Tubulin Inhibitors

  摘要：

  Heat shock protein 27 (Hsp27) is a chaperone protein, and its expression is increased in response to various stress stimuli including anticancer chemotherapy, which allows the cells to survive and causes drug resistance. We previously identified lead compounds that bound to Hsp27 and tubulin via proteomic approaches. Systematic ligand based optimization in the current study significantly increased the cell growth inhibition and apoptosis inducing activities of the compounds. Compared to the lead compounds, one of the new derivatives exhibited much better potency to inhibit tubulin polymerization but a decreased activity to inhibit Hsp27 chaperone function, suggesting that the structural modification dissected the dual targeting effects of the compound. The most potent compounds 20 and 22 exhibited strong cell proliferation inhibitory activities at subnanomolar concentration against 60 human cancer cell lines conducted by Developmental Therapeutic Program at the National Cancer Institute and represented promising candidates for anticancer drug development.

  新型磺酰苯胺类似物可抑制乳腺癌细胞中芳香化酶的表达和活性，而不受COX-2抑制作用的影响。

  摘要：

  芳香酶是治疗雌激素受体阳性乳腺癌的特别有吸引力的靶标。前列腺素可提高乳腺癌细胞中的芳香酶水平，而COX抑制剂则可降低芳香酶水平。描述了衍生自COX-2选择性抑制剂NS-398的一系列新型磺酰苯胺类似物的合成和生物学评估。这些化合物以剂量和时间依赖性方式抑制SK-BR-3乳腺癌细胞中的芳香化酶活性。还在乳腺癌细胞中研究了这些化合物对COX-2抑制的作用。结构活性分析未发现芳香化酶抑制和COX-2抑制之间的相关性。微粒体芳香化酶抑制研究排除了直接酶抑制的可能性。实时PCR分析表明，磺酰苯胺类似物可减少SK-BR-3细胞中的芳香化酶基因转录。这些研究表明，新型磺酰苯胺化合物可独立于COX-2抑制而抑制SK-BR-3乳腺癌细胞中的芳香酶活性和转录。

• Novel Sulfonanilide Analogues Suppress Aromatase Expression and Activity in Breast Cancer Cells Independent of COX-2 Inhibition
  作者：Bin Su、Edgar S. Diaz-Cruz、Serena Landini、Robert W. Brueggemeier

  DOI：10.1021/jm051126f

  日期：2006.2.1

  of these compounds on COX-2 inhibition is investigated in breast cancer cells as well. Structure-activity analysis does not find a correlation between aromatase suppression and COX-2 inhibition. Microsomal aromatase inhibition studies rule out the possibility of direct enzyme inhibition. Real-time PCR analysis demonstrates that the sulfonanilide analogues decrease aromatase gene transcription in SK-BR-3

• Lead optimization of COX-2 inhibitor nimesulide analogs to overcome aromatase inhibitor resistance in breast cancer cells
  作者：Bin Su、Shiuan Chen

  DOI：10.1016/j.bmcl.2009.09.109

  日期：2009.12

  A series of COX-2 selective inhibitor nimesulide derivatives were synthesized. Their anti-cell proliferation activities were evaluated with a long-term estrogen deprived MCF-7aro (LTEDaro) breast cancer cell line, which is the biological model of aromatase inhibitor resistance for hormone-dependent breast cancer. Compared to nimesulide which inhibited LTEDaro cell proliferation with an IC50 at 170.30 mu M, several new compounds showed IC50 close to 1.0 mu M. (C) 2009 Elsevier Ltd. All rights reserved.
