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 μΜ 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.
披露了用于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sigma-2受体结合基团和诱导
铁死亡基团的化合物。至少一种所述的分子物种在体外对人类胰腺癌细胞表现出低于5μΜ的IC50值。给予该物种的治疗促进了小鼠模型系统中胰腺癌肿瘤的萎缩,并导致实验动物在控制疗法仅提供30%或40%存活率的时间段内100%的存活。还披露了分子物种的合成方法。
