Methods and compositions for treating cancers such as pancreatic cancer and synovial sarcoma are disclosed. Compounds comprising a sigma-2 receptor-binding moiety and a ferroptosis-inducing moiety are described. At least one described molecular species exhibits an IC50 value below 5 μM against human pancreatic cancer cells in vitro. Administration of this species promoted shrinkage of pancreatic cancer tumors in a murine model system in vivo, and led to 100% survival of experimental animals over a time course in which control therapies provided only 30% or 40% survival. Methods of synthesis of molecular species are also disclosed.
本研究公开了治疗胰腺癌和滑膜肉瘤等癌症的方法和组合物。描述了包含σ-2 受体结合分子和
铁变态反应诱导分子的化合物。至少有一种所述分子化合物在体外对人胰腺癌细胞的 IC50 值低于 5 μM。在体内的小鼠模型系统中,服用这种物质可促进胰腺癌肿瘤的缩小,并使实验动物在对照疗法仅能提供 30% 或 40% 存活率的时间过程中 100% 存活。还公开了分子物种的合成方法。
