实施例 2、 苯并吡喃化合物抑制人肺成纤维细胞的增殖和活力实验
材料如下:
细胞: 人肺成纤维细胞 (human lung fibroblasts, WI26 药物: 由上述实
施例得到的化合物 1 (厦门霉素 C), 化合物 2 (厦门霉素)
Figure imgf000008_0001
其 中, 采用化合物 1的为药物处理实验组, 采用化合物 2为药物处理对比组。
方法: 将生长至 70-80%融合之 WI26细胞 0. 25%胰酶消化后接种于 96孔板, 每孔 1 X 103个细胞。 24小时后换液并加药, 药物处理实验组化合物 1终浓度为 15 g/ml, 溶 剂 DMS0浓度为 1/1000, 对照组为 DMS0, 终浓度为 1/1000。 药物处理对比组化合物 2 终浓度为 30 μδ/πι1 , 溶剂 DMS0浓度为 1/1000, 对照组为 DMS0, 终浓度为 1/1000。 加 药 0, 1, 2 , 3, 4, 5, 6天后分别测量细胞活力。 测量方法为, 吸出培养基, 每孔加入 完全培养基 100 μΐ及 CCK-8试剂 10 μ1, 培养箱孵育 60分钟后酶标仪测量光吸收值, 波长为 450nm。 实验重复 3次。
实验结果如图 2所示, 由附图可得知: 化合物 1能够抑制人肺成纤维细胞的增殖。 当给药量为 15 g/ml , 给药一天后, 给药组与对照组相比具有显著性的差异, 抑制率 达到 13. 8%。 给药六天后, 抑制率为 38%。 因此, 本发明的苯并吡喃化合物可用于制备 抗肺纤维化药物。 实验组与对比组相比, 化合物 1的有效浓度降低一倍, 同时抑制率比 化合物 2提高近 10%, 因此活性大大优于已知化合物。 此外, 从化合物 1对于人肺成纤 维细胞的增殖抑制效果的时间曲线上判断, 化合物 1与厦门霉素均具有低毒性的特点。 通过改变侧链的结构, 使得化合物 1的活性提升而毒性相对较低, 属于本领域的难点。 根据化合物 1的活性实验结果, 本领域技术人员可知, 对该化合物 1氨基进行修饰产生 的化合物以及 n指代的碳链加长形成的化合物(SP : 权 1限定的化合物)也必然具有相 当的活性。
对比组实验结果如图 3所示, 由附图可得知: 化合物 2虽然能够抑制人肺成纤维细 胞的增殖。 但药量为 30 g/ml , 给药一天后, 给药组与对照组相比具有显著性的差异 抑制率达到 10%。 给药六天后, 抑制率为 28. 5%。
以上对本发明的具体实施例进行了描述。 需要理解的是, 本发明并不局限于上述特 定实施方式, 本领域技术人员可以在权利要求的范围内做出各种变形或修改, 这并不影 响本发明的实质内容。 中謁 H生物菌种保藏管理委、¾会
