  4,8-Dimethylcoumarin Inhibitors of Intestinal Anion Exchanger slc26a3 (Downregulated in Adenoma) for Anti-Absorptive Therapy of Constipation

  摘要：

  The chloride/bicarbonate exchanger SLC26A3 (downregulated in adenoma) is expressed mainly in colonic epithelium, where it dehydrates the stool by facilitating the final step of chloride and fluid absorption. SLC26A3 inhibition has predicted efficacy in various types of constipation including that associated with cystic fibrosis. We previously identified, by high-throughput screening, 4,8-dimethylcoumarin inhibitors of murine slc26a3 with IC50 down to similar to 150 nM. Here, we synthesized a focused library of forty-three 4,8-dimethylcoumarin analogues. Structure-activity studies revealed the requirement of 4,8-dimethylcoumarin-3-acetic acid for activity. The most potent inhibitors were produced by replacements at C7, including 3-iodo- (4az) and 3-trifluoromethyl- (4be), with IC50 of 40 and 25 nM, respectively. Pharmacokinetics in mice showed predicted therapeutic concentrations of 4az for >72 h following a single 10 mg/kg oral dose. 4az at 10 mg/kg fully normalized stool water content in a loperamide-induced mouse model of constipation. The favorable inhibition potency, selectivity within the SLC26 family, and pharmacological properties of 4az support its further preclinical development.

  使用 DMSO/HBr 将硫醇氧化为磺酰衍生物的高效且温和的方法

  摘要：

  通过二甲基亚砜/溴化氢对硫醇进行氧化官能化，描述了一种温和实用的合成磺酰衍生物的方法，该衍生物在药物、材料和有机合成中具有广泛的应用。DMSO/HBr 的简单条件、低成本和易得性，以及转化的多功能性，使得该策略在合成各种磺酰衍生物（包括磺酰胺、磺酰氟、磺酰叠氮化物和磺酸盐）方面非常有效。机理研究表明，DMSO 作为末端氧化剂，HBr 既作为亲核试剂又作为氧化还原介体来转移氧原子。

  A mild and practical method for synthesizing sulfonyl derivatives, which have a wide range of applications in pharmaceuticals, materials, and organic synthesis, was described through the oxidative functionalization of thiols with DMSO/HBr. The simple conditions, low cost and ready availability of DMSO/HBr, as well as the versatility of the transformations, make this strategy very powerful in synthesizing
