Chan'su, exhibits potent antitumor activity. However, serious toxicity and small therapeutic window limits its drug development. In the present study, to our knowledge, novel 3,11-bispeptide ester arenobufagin derivatives have been firstly designed and synthesized on the base of our previous discovery of active 3-monopeptide ester derivative. The in vitro antiproliferative activity evaluation revealed that
沙蟾毒精是从中药蝉速中分离出来的蟾蜍二烯内酯之一,具有强大的抗肿瘤活性。然而,严重的毒性和小的治疗窗限制了其药物开发。在本研究中,据我们所知,在我们先前发现的具有活性的3-单肽酯衍生物的基础上,首次设计并合成了新型3,11-双肽酯槟榔衍生物。体外抗增殖活性评价表明,C3 和 C11 羟基部分对细胞毒活性和选择性有重要影响。化合物ZM350在 A549 裸鼠异种移植模型中以 10 mg/kg 的剂量显着抑制肿瘤生长 58.8%。因此,复配ZM350还呈现出浓度依赖性细胞凋亡诱导和对 hERG 钾通道和 Cav1.2 钙通道的低抑制作用。我们的研究表明,新型 3,11-双肽酯衍生物将有利于进一步开发砂蟾毒精的抗肿瘤剂。
