  Highly Selective Aldose Reductase Inhibitors. 1. 3-(Arylalkyl)-2,4,5-trioxoimidazolidine-1-acetic Acids

  摘要：

  A series of 3-(arylalkyl)-2,4,5-trioxoimidazolidine-1-acids (1) was prepared and tested for aldose reductase (AR) and aldehyde reductase (ALR) inhibitory activities. These compounds showed strong inhibitory activity against AR without significant inhibitory activity for ALR. The ratio of IC50(ALR)/IC50(AR) was > 1000 in some compouds. On the basis of pharmacological tests such as the recovery of reduced motor nerve conduction velocity and toxicological profile, 3-(3-nitrobenzyl)-2,4,5-trioxoimidazolidine-1-acid (NZ-314) was selected as the candidate for clinical development.

  氯化铵促进微波辐照下单取代脲的快速合成

  摘要：

  氯化铵在微波辐射下促进单取代脲的选择性形成。大多数亲核试剂、酸不稳定官能团和保护基团在该反应中具有良好的耐受性。通过避免过渡金属和无机酸，该方法为合成单取代脲及其类似物提供了一种更可持续的替代方案。

  Ammonium chloride promotes the selective formation of monosubstituted ureas under microwave irradiation. Most nucleophiles, acid-labile functionalities, and protecting groups are well tolerated in this reaction. By avoiding transition metals and mineral acids, this methodology offers a more sustainable alternative for the synthesis of monosubstituted ureas and their analogs.
