In a search for effective PPAR-γ agonists, 110 clinical drugs were screened via molecular docking, and 9 drugs, including parecoxib, were selected for subsequent biological evaluation. Molecular docking of parecoxib to the ligand-binding domain of PPAR-γ showed high binding affinity and relevant binding conformation compared with the PPAR-γ ligand/antidiabetic drug rosiglitazone. Per the docking result, parecoxib showed the best PPAR-γ transactivation in Ac2F rat liver cells. Further docking simulation and a luciferase assay suggested parecoxib would be a selective (and partial) PPAR-γ agonist. PPAR-γ activation by parecoxib induced adipocyte differentiation in 3T3-L1 murine preadipocytes. Parecoxib promoted adipogenesis in a dose-dependent manner and enhanced the expression of adipogenesis transcription factors PPAR-γ, C/EBPα, and C/EBPβ. These data indicated that parecoxib might be utilized as a partial PPAR-γ agonist for drug repositioning study.
在寻找有效的过氧化物酶体增殖物激活受体γ(PPAR-γ)激动剂的过程中,通过分子对接筛选了110种临床药物,包括帕罗西汀在内的9种药物被选出来进行后续的生物学评估。与PPAR-γ配体/抗糖尿病药物罗格列酮相比,帕罗西汀与PPAR-γ配体结合域的分子对接显示出高结合亲和力和相关结合构象。根据对接结果,帕罗西汀在Ac2F大鼠肝细胞中表现出最佳的PPAR-γ反式激活作用。进一步的对接模拟和荧光素酶测定表明,帕罗西汀可能是一种选择性(部分)PPAR-γ激动剂。帕罗西汀激活PPAR-γ可诱导3T3-L1小鼠前脂肪细胞的脂肪细胞分化。帕罗西汀以剂量依赖的方式促进脂肪生成,并增强脂肪生成转录因子PPAR-γ、C/EBPα和C/EBPβ的表达。这些数据表明,帕罗西汀可作为部分PPAR-γ激动剂用于药物重新定位研究。
