产品信息

RSL3 is a VDAC-independent ferroptosis activator with selectivity for tumor cells bearing oncogenic RAS. RSL3 is the inhibitor of the glutathione peroxidase 4, which can inhibit the cysteine/glutamate amino acid transporter system xc- that blocks GSH synthesis (IC50: 100 nM).

靶点活性

GSH:100 nM

体内活性

Prostaglandin-endoperoxide synthase (PTGS) is the key enzyme in prostaglandin biosynthesis. There are two isozymes of PTGS: a constitutive PTGS1 and an inducible PTGS2. PTGS2 encoding cyclooxygenase-2 (COX-2) is significantly upregulated after treatment with RSL3 and erastin in mice[1].

体外活性

Ferroptosis-inducing compounds inactivate GPX4 by direct binding or by depleting glutathione.After binding to GPX4, RSL3 inactivates GPX4 to induce ROS production from lipid peroxidation. RSL3's ability to induce synthetic lethality with oncogenic RAS is rapid and quite potent. This compound inhibits the growth of BJ-TERT/LT/ST/RASV12 and DRD cells as low as 10 ng/mland started to kill sensitive cells as early as 8 hr after treatment[1][2].

溶解度

DMSO:44.1 mg/mL (100 mM)

细胞实验

TERT/LT/ST/RASV12 cells are seeded in 10 cm dishes and treated with 1 µM staurosporine, 10 µg/ml erastin, 20 µg/ml RSL5, and 1 µg/ml RSL3 for 16 hr. Both dying cells and live cells in each 10 cm dish are harvested and collected in the same 15 ml tubes by centrifuging cell suspension at 1000 rpm for 5 min. (Only for Reference)
