A series of prodrugs for nitroreductase (NTR) based 4-β-amino-4′- Demethylepipodophyllotoxin as potential anticancer agents were synthesized, and their antiproliferative activities in vitro showed compounds 2b (IC50 = 0.77, 0.83 and 1.19 μM) and 2d (IC50 = 0.98, 0.91 and 1.58 μM) were greatly selectively toxic to tumor cells A-549, HeLa and HepG2, respectively, and lower damage to normal WI-38 cells
合成了一系列基于硝基还原酶 (NTR) 的 4-β-氨基-4'-去甲基表鬼臼毒素作为潜在抗癌剂的前药,其体外抗增殖活性显示化合物2b (IC 50 = 0.77, 0.83 和 1.19 μM) 和2d ( IC 50 = 0.98, 0.91 和 1.58 μM) 分别对肿瘤细胞 A-549、HeLa 和 HepG2 具有极大的选择性毒性,与阳性药物依托泊苷和去甲基表鬼臼毒素相比,对正常 WI-38 细胞的损伤更低,并诱导细胞周期停滞在 G2/M 期,HeLa 细胞中 G1 期的数量随之减少,并伴有细胞凋亡。此外,分子对接模型表明化合物2b和2d似乎与 NTR 1DS7 形成稳定的键。总之,这些缀合物有可能被开发为抗肿瘤药物。
