and, in some cases, with cancer. For many years, research has been focused on finding new AKR1B1 inhibitors (ARIs) to overcome these diseases. Despite the efforts, most of the new drug candidates failed because of their poor pharmacokinetic properties and/or unacceptable side effects. Here we report the synthesis of a series of 1-oxopyrimido[4,5-c]quinoline-2-acetic acid derivatives as novel ARIs. IC50
人醛糖还原酶(AKR1B1,AR)是多元醇途径的关键酶,在高葡萄糖浓度下(如在糖尿病患者中发现的那样)催化葡萄糖还原为山梨糖醇。实际上,AKR1B1过表达与糖尿病继发性并发症有关,在某些情况下与癌症有关。多年来,研究一直集中在寻找新的AKR1B1抑制剂(ARIs)来克服这些疾病。尽管做出了努力,但大多数新药候选药物仍因药代动力学性能差和/或不良副作用而失败。在这里我们报告了一系列的1-氧嘧啶基[4,5-c]喹啉-2-乙酸衍生物的合成作为新型ARI。IC50分析法和X射线晶体学研究证明,这些化合物具有针对AKR1B1的高效力和选择性,有望在进一步的药物开发中大放异彩。基于确定的具有先导化合物的X射线结构,我们设计并合成了第二个系列,得到了先导化合物68(Kiappvs。AKR1B1 = 73 nM)。这些化合物与先前报道的具有抗有丝分裂活性的2-氨基嘧啶基[4,5-c]喹啉-1(2H)-on
