  SAR studies of 4-pyridyl heterocyclic anilines that selectively induce autophagic cell death in von Hippel-Lindau-deficient renal cell carcinoma cells

  摘要：

  We recently identified a class of pyridyl aniline thiazoles (PAT) that displayed selective cytotoxicity for von Hippel-Lindau (VHL) deficient renal cell carcinoma (RCC) cells in vitro and in vivo. Structure-activity relationship (SAR) studies were used to develop a comparative molecular field analysis (CoMFA) model that related VHL-selective potency to the three-dimensional arrangement of chemical features of the chemotype. We now report the further molecular alignment-guided exploration of the chemotype to discover potent and selective PAT analogues. The contribution of the central thiazole ring was explored using a series of five-and six-membered ring heterocyclic replacements to vary the electronic and steric interactions in the central unit. We also explored a positive steric CoMFA contour adjacent to the pyridyl ring using Pd-catalysed cross-coupling Suzuki-Miyaura, Sonogashira and nucleophilic displacement reactions to prepare of a series of aryl-, alkynyl-, alkoxy- and alkylamino-substituted pyridines, respectively. In vitro potency and selectivity were determined using paired RCC cell lines: the VHL-null cell line RCC4 and the VHL-positive cell line RCC4-VHL. Active analogues selectively induced autophagy in RCC4 cells. We have used the new SAR data to further develop the CoMFA model, and compared this to a 2D-QSAR method. Our progress towards realising the therapeutic potential of this chemotype as a targeted cytotoxic therapy for the treatment of RCC by exploiting the absence of the VHL tumour suppressor gene is reported.

  recently identified a 4-pyridyl-2-anilinothiazole (PAT) with selective cytotoxicity against VHL-deficient renal cells mediated by induction of autophagy and increased acidification of autolysosomes. We report exploration of structure−activity relationships (SAR) around this PAT lead. Analogues with substituents on each of the three rings, and various linkers between rings, were synthesized and tested in

  肾细胞癌 (RCC) 对预后不良的晚期 RCC 的标准治疗无效；因此，晚期 RCC 的治疗代表了未满足的临床需求。von Hippel-Lindau (VHL) 肿瘤抑制基因在大多数 RCC 中发生突变或失活。我们最近发现了一种 4-pyridyl-2-anilinothiazole (PAT)，它对 VHL 缺陷的肾细胞具有选择性的细胞毒性，这种毒性是通过诱导自噬和增加自溶酶体的酸化来介导的。我们报告了围绕此 PAT 导联的构效关系 (SAR) 的探索。使用成对的 RCC4 细胞系合成并在体外测试三个环中每个环上具有取代基的类似物以及环之间的各种接头。描述不同化学特征对效力的相对空间贡献的等高线图说明了一个区域，与吡啶环相邻，具有进一步发展的潜力。探索这个域的例子验证了这种方法，并可能为开发这种新的化学型作为 RCC 治疗的靶向方法提供机会。
