ErSO is an activator of the unfolded protein response which eradicates human breast tumors in mice. ErSO activates the anticipatory unfolded protein response (a-UPR) and induces rapid and selective necrosis of ERα-positive breast cancer cell lines in vitro. In multiple orthotopic models, ErSO treatment given either orally or intraperitoneally for 14 to 21 days induced tumor regression without recurrence. In a cell line tail vein metastasis model, ErSO was also effective at inducing regression of most lung, bone, and liver metastases. ErSO treatment induced almost complete regression of brain metastases in mice carrying intracranial human breast cancer cell line xenografts.

ErSO是一种选择性预期折叠蛋白反应 (a-UPR) 激活剂。ErSO 通过 ERα 诱导 a-UPR 产生强而持久的细胞毒性。ErSO 可用于癌症研究。
