western bolt analysis. Our study demonstrated that compounds 8b and 14e suppressed effectively the expression of α-smooth muscle actin, fibronectin and collagen in NIH-3T3. Preliminary structure-activity analysis revealed that 14-deoxygenation and 19-carboxylation of andrographolide could significantly improve its anti-fibrotic effect, which made 14-deoxyandrographolide-19-oic acid and 14-deoxy-11,12-di
针对小鼠成纤维细胞系NIH-3T3 ,设计,合成并筛选了一系列14-脱氧穿心莲内酯19-oic酸和14-脱氧穿心莲内酯19-oic衍生物。发现13种化合物8a-f,14a-c,14e-f和18a-b具有比穿心莲内酯更好的抗纤维化活性,其中化合物8b和14e表现出最佳活性,对NIH-的IC 50值为12.86和13.57μM。 3T3。进一步的抗纤维化研究进行了PCR和Western螺栓分析。我们的研究表明,化合物8b和14e有效地抑制了NIH-3T3中α-平滑肌肌动蛋白,纤连蛋白和胶原蛋白的表达。初步的结构活性分析表明穿心莲内酯的14-脱氧和19-羧化可以显着提高其抗纤维化作用,从而使14-脱氧穿心莲内酯19-oic酸和14-脱氧-11,12-二氢脱水穿心莲内酯-19-oic酸。新型抗纤维化药物开发的有希望的线索。
