Notes: Ferrostatin-1 diyne is a ferroptosis inhibitor and analog of ferrostatin-1 (Item No. 17729).{44000} It inhibits cell death induced by erastin (Item No. 17754) in HT-1080 cells when used at concentrations ranging from 0.01 to 1 μM. Ferrostatin-1 diyne contains a diyne small vibrational tag and has been used to assess localization of ferrostatin-1 in HT-1080 cells using stimulated Ramen scattering microscopy.
