  Nanomolar Potency and Metabolically Stable Inhibitors of Kidney Urea Transporter UT-B

  摘要：

  Urea transporters, which include UT-B in kidney microvessels, are potential targets for development of drugs with a novel diuretic ('urearetic') mechanism. We recently identified, by high-throughput screening, a triazolothienopyrimidine UT-B inhibitor, 1, that selectively and reversibly inhibited urea transport with IC50 = 25.1 nM and reduced urinary concentration in mice (Yao et al. J. Am. Soc. Nephrol., in press). Here, we analyzed 273 commercially available analogues of 1 to establish a structure-activity series and synthesized a targeted library of 11 analogues to identify potent, metabolically stable UT-B inhibitors. The best compound, {3-[4-(1,1-difluoroethyl)benzenesulfonyl]thieno[2,3-e][1,2,3]triazolo[1,5-a]pyrimidin-5-y1}thiophen-2-ylmethylamine, 3k, had IC50 of 23 and 15 nM for inhibition of urea transport by mouse and human UT-B, respectively, and similar to 40-fold improved in vitro metabolic stability compared to 1. In mice, 3k accumulated in kidney and urine and reduced maximum urinary concentration. Triazolothienopyrimidines may be useful for therapy of diuretic-refractory edema in heart and liver failure.

  3-azido-2-methylbut-3-en-2-ol under ultraviolet irradiation at room temperature is achieved, giving rise to 2-(arylsulfonyl)acetonitriles in moderate to good yields. Alkyl iodide is also workable under these conditions. This transformation proceeds smoothly under mild conditions with a broad substrate scope. Various functional groups are compatible including amino, ester, halo, and trifluoromethyl groups. No metal catalyst

  在室温下紫外线照射下，二氧化硫与芳基碘化物和3-叠氮基-2-甲基丁-3-烯-2-醇的无金属插入得以实现，从而以中等至良好的产率产生了2-（芳基磺酰基）乙腈。烷基碘化物在这些条件下也是可行的。该转化在温和条件下在宽范围的底物范围内平稳进行。各种官能团相容，包括氨基，酯，卤素和三氟甲基。在反应过程中不需要金属催化剂或添加剂。机理研究表明，在紫外线照射下，碘化芳基会原位生成芳基，然后通过插入二氧化硫进行芳基磺酰化，生成芳基磺酰基自由基中间体。

  active site cysteine thiolate into an electrophilic sulfenyl amide residue. Reduction of the sulfenyl amide by biological thiols regenerates the native cysteine residue. Here we explored fundamental chemical reactions that may enable covalent capture of the sulfenyl amide residue in oxidized PTP1B. Various sulfone-containing carbon acids were found to react readily with a model peptide sulfenyl amide via

  蛋白质酪氨酸磷酸酶1B（PTP1B）的氧化还原调节涉及活性位点半胱氨酸硫醇盐的氧化转化为亲电子的亚磺酰胺残基。生物硫醇对亚磺酰胺的还原可再生天然半胱氨酸残基。在这里，我们探索了基本的化学反应，该化学反应可以共价捕获氧化的PTP1B中的亚磺酰胺残基。发现各种含砜的碳酸通过磺酰氨基在磺酰酰胺中的亲电子硫中心上的攻击而容易地与模型肽磺酰酰胺反应。表征产物和这些反应的速率。结果表明，砜稳定的碳负离子捕获肽亚磺酰胺残基可以减慢但不能完全防止，硫醇介导的相应的含半胱氨酸肽的生成。含砜的碳酸可能是构建药物的有用成分，这些药物可通过瞬时共价捕获胰岛素信号传导过程中产生的亚磺酰胺酰胺羰基来降低细胞中的PTP1B活性。
