基于肿瘤细胞响应性释药的安吖啶缀合物的设计合成及抗肿瘤活性研究(英文)
发布时间:2023-02-23 10:17
目的改善抗肿瘤药物安吖啶的药效学性质以期增强其靶向抗肿瘤作用。方法基于拼合设计原理,以安吖啶为原料,经与吡啶-2-过硫乙醇偶联、与巯基多胺硫交换反应合成安吖啶-二硫键-胺基缀合物;采用MTT法测试目标化合物8a(m=1,R=H)对人肝癌细胞(HepG2)的体外生长抑制活性;在H22肝癌细胞移植的荷瘤小鼠模型上测试化合物8a的体内抗肿瘤作用。结果与结论合成了5个未见文献报道的安吖啶缀合物,目标化合物的结构经核磁共振氢谱、核磁共振碳谱及高分辨质谱确证。体外试验结果表明,化合物8a在谷胱甘肽作用下发生二硫键降解并释放出安吖啶原药;高谷胱甘肽水平能够增强化合物8a对人肝癌细胞HepG2的生长抑制作用;体内活性试验表明,在1.25 mg·kg-1剂量下化合物8a对荷瘤小鼠的肿瘤(hepatoma H22)生长抑制率达到51.3%,荷瘤小鼠的生存时间明显延长。■
