Human neutrophil elastase (HNE) is a serine protease that degrades matrix proteins. An excess of HNE may trigger several pathological conditions, such as psoriasis. In this work, we aimed to synthesize, characterize and formulate new HNE inhibitors with a 4-oxo-β-lactam scaffold with less toxicity, as well as therapeutic index in a psoriasis context. HNE inhibitors with 4-oxo-β-lactam scaffolds were
人嗜中性粒细胞弹性蛋白酶(HNE)是一种丝氨酸蛋白酶,可降解基质蛋白。HNE过量可能引发多种病理状况,例如牛皮癣。在这项工作中,我们旨在合成,表征和配制新的HNE抑制剂,并使用具有较小毒性的4-氧代-β-内酰胺支架,以及在牛皮癣方面的治疗指标。合成了具有4-氧代-β-内酰胺骨架的HNE抑制剂,并通过NMR,FTIR,熔点,质谱和元素分析对其进行了表征。进行了体外细胞毒性和丝氨酸蛋白酶测定。选择具有最高细胞生存力的化合物(AAN-16)掺入乳液(AAN-16 E)和微乳液(AAN-16 ME)中。根据感官特性,pH,流变学,液滴尺寸分布,体外药物释放和体内银屑病活性。所有化合物均已根据分析方法成功合成,收率良好。两种制剂均表现出合适的理化性质。AAN-16 E在鼠类牛皮癣模型中显示出最有希望的治疗效果。总体而言,合成了具有高选择性活性的新型HNE抑制剂,并将其掺入具有治疗牛皮癣潜力的局部乳剂中。
