  2-((Benzimidazol-2-yl)thio)-1-arylethan-1-ones: Synthesis, crystal study and cancer stem cells CD133 targeting potential

  摘要：

  In order to develop a potent anti-tumor agent that can target both cancer stem cells and the bulk of tumor cells, a series of 2-((benzimidazol-2-yl)thio)-1-arylethan-1-ones 5a-o was synthesized. All compounds were evaluated for their anti-proliferative activity towards colon HT-29 cancer cell line. In addition, their inhibitory effect against cell surface expression of CD133, a potent cancer stem cells (CSCs) marker, in the same cells was evaluated by flow cytometry at 10 mu M. Compound 51 emerged as the most active anti-proliferative analog against HT-29 (IC50 = 18.83 +/- 1.37 mu M), that almost equipotent as 5-fluorouracil (IC50 = 15.83 +/- 1.63 mu M) with 50.11 +/- 4.05% inhibition effect on CD133 expression, suggested dual targeted effect. Also, compounds 5h, 5j, 5k and 5m-o inhibited the expression of CD133 with more than 50%. The SAR study pointed out the significance of substitution of the pendent phenyl group with lipophilic electron-donating groups or replacing it by 2-thienyl or 2-furyl groups.

  On account of its poor prognosis and deficiency of therapeutic stratifications, triple negative breast cancer continues to form the causative platform of an incommensurate number of breast cancer deaths. Aiming at the development of potent anticancer agents as a continuum of our previous efforts, a novel series of 2-((benzimidazol-2-yl)thio)-1-arylethan-1-ones 5a–w was synthesized and evaluated for its anti-proliferative activity towards triple negative breast cancer (TNBC) MDA-MB-468 cells. Compound 5k was the most active analog against MDA-MB-468 (IC50 = 19.90 ± 1.37 µM), with 2.1-fold increased activity compared to 5-fluorouracil (IC50 = 41.26 ± 3.77 µM). Compound 5k was able to induce apoptosis in MDA-MB-468, as evidenced by the marked boosting in the percentage of florecsein isothiocyanate annexin V (Annexin V–FITC)-positive apoptotic cells (upper right (UR) + lower right (LR)) by 2.8-fold in comparison to control accompanied by significant increase in the proportion of cells at pre-G1 (the first gap phase) by 8.13-fold in the cell-cycle analysis. Moreover, a quantitative structure activity relationship (QSAR) model was established to investigate the structural requirements orchestrating the anti-proliferative activity. Finally, we established a theoretical kinetic study.

  由于其预后不良和治疗分层的不足，三阴性乳腺癌继续成为导致乳腺癌死亡人数不相称的原因平台。作为我们之前努力的连续体，旨在开发有效的抗癌药物，合成了一系列新型 2-((benzimidazol-2-yl)thio)-1-aryllethan-1-ones 5a–w 并评估了其抗癌效果。 -对三阴性乳腺癌（TNBC）MDA-MB-468细胞的增殖活性。化合物 5k 是 MDA-MB-468 活性最强的类似物 (IC50 = 19.90 ± 1.37 µM)，与 5-氟尿嘧啶相比，活性增加了 2.1 倍 (IC50 = 41.26 ± 3.77 µM)。化合物 5k 能够诱导 MDA-MB-468 细胞凋亡，异硫氰酸荧光素膜联蛋白 V (Annexin V–FITC) 阳性凋亡细胞的百分比显着增加（右上 (UR) + 右下 (LR)） ）与对照相比增加了 2.8 倍，同时在细胞周期分析中，G1 前（第一个间隙期）的细胞比例显着增加了 8.13 倍。此外，还建立了定量结构活性关系（QSAR）模型来研究协调抗增殖活性的结构要求。最后，我们建立了理论动力学研究。
