最近鉴定慢性糖尿病并发症的治疗方法的努力导致发现了一系列新的高效和选择性的(2-芳基氨基甲酰基-苯氧基)乙酸醛糖还原酶抑制剂。化合物类别的特征是核心模板,该模板利用分子内氢键将药效基团的关键结构元件定位在构象中,从而促进了高结合亲和力。铅候选物,例如40,5-氟-2-(4-溴-2-氟-苄硫代氨基甲酰基)-苯氧基乙酸,抑制醛糖还原酶,IC(50)为30 nM,而对醛还原酶的活性低1100倍,是一种与活性醛解毒有关的酶。另外,实施例40在4天STZ诱导的糖尿病大鼠模型中以31mg / kg / d po的ED(50)降低了神经山梨糖醇水平。

potassium complex was used as a transitionmetal-free catalyst for reduction of primary amides to corresponding primary amines under ambient conditions. Only 2 mol% loading of the catalyst exhibits a broad substrate scope including aromatic, aliphatic and heterocyclic primary amides with excellent functional group tolerance. This method was applicable for reduction of chiral amides and utilized for the synthesis
