  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).

  of 4-substituted 2-acylphenoxyacetic acids give a mixture of benzofurans and 2-benzofurancarboxylic acids. The relative yields of benzofurans and 2-benzofurancarboxylic acids depend on the substituents on the benzene ring of the 2-acylphenoxyacetic acids. Electron-withdrawing substituents such as nitro groups favor the formation of 2-benzofurancarboxylic acids. On the other hand, the formation of benzofurans

  An unprecedented oxidative dimerization by palladium catalysis has been developed using PhI(OPiv)2 as a by-standing oxidant. This provides a facile method for the synthesis of quaternary 2,3′-bibenzofuran-2′(3′)-ones from readily accessible substrates. A plausible mechanism involving a Pd(II)–Pd(IV) catalytic cycle is proposed; a trace amount of water is required for subsequent oxidation.
