Due to its production of potent antimicrobial oxidants including hypochlorous acid, human myeloperoxidase (MPO) plays a critical role in innate immunity and inflammatory diseases. Thus MPO is an attractive target in drug design. (Aminoalkyl)fluoroindole derivatives were detected to be very potent MPO inhibitors; however, they also promote inhibition of the serotonin reuptake transporter (SERT) at the
由于其有效的抗微生物氧化剂(包括次氯酸)的产生,人髓过氧化物酶(MPO)在先天免疫和炎性疾病中起着至关重要的作用。因此,MPO是药物设计中有吸引力的目标。检测到(氨基烷基)氟吲哚衍生物是非常有效的MPO抑制剂。然而,它们还促进了在相同浓度范围内对5-羟色胺再摄取转运蛋白(SERT)的抑制。通过基于结构的药物设计,合成了一系列新的3-烷基吲哚衍生的MPO抑制剂,并评估了它们对MPO介导的牛磺酸氯化和低密度脂蛋白氧化以及对SERT抑制的作用。侧链上有三个碳原子和一个酰胺基的氟吲哚化合物的选择性指数为35(K i / IC50)对MPO活性具有高度抑制作用(IC 50 = 18 nM),而其对SERT的作用在微摩尔范围内。讨论了分子的结构-功能关系,作用机理和安全性。
