79 μM. Eight compounds (3c, 3d, 3e, 3f, 3j, 3m, 3q and 3r) also displayed inhibitory effect on lipid accumulation in human HepG2 cells. Additionally, the molecular docking study revealed that compound 3m having good inhibition activity against FAS and lipid accumulation also showed promising binding affinities with hFAS, while its binding model with hFAS (PDB ID: 4PIV) was different from that of reference
设计,合成和表征了具有D-(-)-泛内酯部分并具有潜在的治疗肥胖作用的一系列新型脂肪酸合成酶(FAS)抑制剂,其中通过单X射线进一步证实了化合物3k的结构衍射。评价了合成化合物对小鼠FAS的抑制活性。主要合成化合物(3g,3i,3k,3l和3n除外)表现出中等的FAS抑制特性,IC 50值在13.68±1.52–33.19±1.39μM范围内,参考抑制剂C75的IC 50值在13.86± 2.79μM范围内。八种化合物(3c,3d,3e,3f,3j,3m,3q和3r)也显示出对人HepG2细胞脂质蓄积的抑制作用。此外,分子对接研究表明,对FAS和脂质蓄积具有良好抑制活性的化合物3m也显示出与hFAS的有希望的结合亲和力,而其与hFAS的结合模型(PDB ID:4PIV)与参考化合物C75不同。
