erastin-2

Erastin2 是一种铁死亡诱导剂，通过与亲脂性自由基捕获抗氧化剂ferrostatin-1或铁螯合剂去铁胺（DFO）来诱导细胞死亡。

SLC7A11-IN-2 (Compound 1) 是一种有效的SLC7A11 xCT抑制剂，通过下调细胞内谷胱甘肽水平并增加氧化应激来破坏 HeLa 细胞的氧化稳态，从而诱导细胞死亡，其 IC50 值为 10.23 μM。分子动力学模拟表明，该化合物的 SLC7A11 结合能力优于 Erastin。SLC7A11-IN-2 主要应用于宫颈癌的研究领域。

Pantothenate Kinase Inhibitor (PANKi) is a reversible inhibitor of pantothenate kinase (PanK; IC50s = 70, 92, and 25 nM for PanK1β, PanK2, and PanK3, respectively), the rate-limiting enzyme in the synthesis of coenzyme A .1It binds to the ATP-PanK3 complex with an apparent binding constant of 300 nM and exhibits mixed-type inhibition with respect to ATP and pantothenate. PANKi inhibits CoA biosynthesis in C3A cells (IC50= 0.9 μM) with no effect on cell viability when used at concentrations up to 8 μM. PANKi (5 μM) synergizes with BSO to induce ferroptosis in PANC-1 cells and sensitizes the cells to imidazole ketone erastin-induced ferroptosis.2 1.Sharma, L.K., Leonardi, R., Lin, W., et al.A high-throughput screen reveals new small-molecule activators and inhibitors of pantothenate kinasesJ.
