生物活性：iFSP1 是 FSP1 (AIFM2) 的选择性有效抑制剂，EC₅₀ 值为 103 nM。iFSP1 可选择性地诱导过表达 FSP1 的 GPX4 敲除细胞发生铁死亡 (ferroptosis)。iFSP1 可增强多种人癌细胞系对铁死亡诱导剂的敏感度，如: (1S,3R)-RSL3 (HY-100218A)。

iFSP1 is a potent, selective and glutathione-independent inhibitor of ferroptosis suppressor protein 1 (FSP1) (AIFM2) with an EC₅₀ of 103 nM. iFSP1 selectively induces ferroptosis in GPX4-knockout cells which overexpressed FSP1. iFSP1 is able to sensitize a variety of human cancer cell lines to the ferroptosis inducer, such as (1S,3R)-RSL3 (HY-100218A)^[1].
