应用
Liproxstatin-1 在细胞活力试验和脂质过氧化测定中用作细胞死亡抑制剂。
生化/生理作用
Liproxstatin-1 是铁死亡的强效抑制剂，铁死亡是一种非凋亡形式的细胞死亡，以铁依赖性致死脂质活性氧簇 (ROS) 蓄积为特征。Liproxstatin-1 在人类细胞和缺血/再灌注诱导的小鼠组织损伤模型中抑制了铁死亡。谷胱甘肽过氧化物酶 4 (Gpx4) 的基因敲除已被证明可引起细胞死亡的铁死亡。Liproxstatin-1 能够抑制 Gpx4 基因敲除小鼠的铁死亡。

Ferroptosis is a form of regulated cell death that is driven by lethal accumulation of lipid peroxides upon inhibition of glutathione peroxidase 4 (GPx4). Deletion of the Gpx4 gene in mice revealed that neurons are sensitive to ferroptosis in vivo. However

Ferroptosis-an iron-dependent, non-apoptotic cell death process-is involved in various degenerative diseases and represents a targetable susceptibility in certain cancers1. The ferroptosis-susceptible cell state can either pre-exist in cells that arise from certain lineages or be acquired during cell-state transitions2-5. However

Ovarian cancer is the deadliest gynecologic cancer. Despite recent advances, clinical outcomes remain poor, necessitating novel therapeutic approaches. To investigate metabolic susceptibility, we performed nutrigenetic screens on a panel of clear cell and serous ovarian cancer cells and identified cystine

Ferroptosis is an iron-dependent regulated necrosis mediated by lipid peroxidation. Cancer cells survive under metabolic stress conditions by altering lipid metabolism, which may alter their sensitivity to ferroptosis. However, the association between lipid metabolism and ferroptosis is not completely understood.
