RSL-3 is an inhibitor of glutathione peroxidase 4 (GPX4) (ferroptosis activator), reduces the expression of GPX4 protein, and induces ferroptotic death of head and neck cancer cell. RSL-3 increases the expression of p62 and Nrf2 and inactivates Keap1 in HN3-rslR cells.

How to use

In Vitro:

RSL-3 (0-8 μM, 72 hours) potently reduces the viability of HN3 cells, with IC50s of 0.48 µM in HN3 and 5.8 µM in HN3-rslR cells, respectively. RSL-3 (0-8 μM, 24 hours) reduces the expression of GPX4 protein, increases the expression of p62 and Nrf2 and inactivates Keap1 in HN3-rslR cells.

In Vivo:

RSL-3 (100 mg/kg, Intratumorally twice per week for 20 days) significantly inhibits the growth of tumor in combination with trigonelline in mice bearing HN3R cells.
