that oral administration of 2g, 2h, 4f, or 6h decreases, most significantly for 4f, the serum levels of alanine aminotransaminase (ALT) and asparate aminotransaminase (AST) in ConA-induced acute livery injury BALB/c mice. Histopathological evaluation liver sections confirmed 4f as a potent, orally active compound for hepatoprotective effects against ConA-induced acute liver injury in BALB/c mice.
大量证据表明,单核细胞/巨噬细胞浸润与多种炎性疾病有关,包括急性肝损伤。单核细胞趋化蛋白1(MCP-1)在巨噬细胞募集过程中起着至关重要的作用。我们在此提出了一种小分子文库和一种可行的快速筛选方法,用于评估抑制MCP-1刺激的RAW264.7细胞趋化性的能力。合成和筛选了53个小分子,四种化合物(2g,2h,4f和6h)显示出抑制作用,IC 50值范围为0.72至20.47μM,使用化合物4f是最有效的。进一步的体内研究表明,口服2g,2h,4f或6h可降低ConA诱导的急性肝损伤BALB / c小鼠的丙氨酸氨基转氨酶(ALT)和天冬酰胺转氨酶(AST)的血清水平,尤其是在4f时。组织病理学评估肝脏切片证实4f是一种有效的口服活性化合物,具有抗ConA诱导的BALB / c小鼠急性肝损伤的肝保护作用。
