  A Novel Series of Non-Carboxylic Acid, Non-Hydantoin Inhibitors of Aldose Reductase with Potent Oral Activity in Diabetic Rat Models:  6-(5-Chloro-3-methylbenzofuran-2-sulfonyl)-2H-pyridazin-3-one and Congeners

  摘要：

  Discovery of a highly selective, potent, and safe non-carboxylic acid, non-hydantoin inhibitor of aldose reductase (AR) capable of potently blocking the excess glucose flux through the polyol pathway that prevails under diabetic conditions has been a long-standing challenge. In response, we did high-throughput screening of our internal libraries of compounds and identified 6-phenylsulfonylpyridazin-2H-3-one, 8, which showed modest inhibition of AR, both in vitro and in vivo. Initial structure-activity relationships concentrated on phenyl substituents and led to 6-(2,4-dichlorophenylsulfonyl)-2H-pyridazin-3-one, 81, which was more potent than 8, both in vitro and in vivo. Incorporation of extant literature findings with other aldose reductase inhibitors, including zopolrestat, resulted in the title inhibitor, 19m, which is one of the most potent and highly selective non-carboxylic acid, non-hydantoin inhibitors of AR yet described (IC50, 1 nM; ED90 vs sciatic nerve sorbitol and fructose, respectively, 0.8 and 4.0 mg/kg). In rats, its oral bioavailability is 98% and it has a favorable plasma t(1/2) (26 +/- 3 h).

  The present invention relates to novel pyridazinone compounds, pharmaceutical compositions comprising those compounds and to methods of using such compounds and compositions to inhibit aldose reductase, lower sorbitol levels and, thus, lower fructose levels, and/or treat or prevent diabetic complications such as diabetic neuropathy, diabetic retinopathy, diabetic nephropathy, diabetic cardiomyopathy, diabetic microangiopathy and diabetic macroangiopathy in mammals. This invention also relates to methods of affording cardioprotection to subjects not suffering from diabetes. This invention also relates to pharmaceutical compositions and kits comprising a combination of an aldose reductase inhibitor (ARI) of this invention and a sorbitol dehydrogenase inhibitor and to methods of using such compositions or kits to treat or prevent the above diabetic complications in mammals. This invention also relates to other combinations with the ARIs of this invention, including combinations with adendsine agonists; NHE-1 inhibitors; glycogen phosphorylase inhibitors; selective serotonin reuptake inhibitors; GABA agonists; antihypertensive agents; 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors; phosphodiesterase-5 inhibitors; and to glucose lowering agents.

  thiols may be oxidized to the sulfonyl chloride at low temperature (−25 °C) by using 3.3 equiv of aqueous sodium hypochlorite. The reaction is rapid, avoids the use of chlorine gas, and succeeds with substrates that have previously been found to afford little or none of the sulfonamide product with other procedures. The method allows the preparation of the sulfonyl fluorides, which are stable enough to

  杂芳族硫醇可通过使用3.3当量的次氯酸钠水溶液在低温（−25°C）下氧化为磺酰氯。该反应是快速的，避免了使用氯气，并且成功地使用了以前发现的底物，该底物在其他方法下几乎没有或根本没有提供磺酰胺产物。该方法允许制备磺酰氟，该磺酰氟足够稳定以被纯化和储存，从而使其成为潜在的有用的单体，可用于平行化学研究中。
