Erastin
Erastin is a cell-permeable ferroptosis activatior and an antitumor agent that is selective for cell expressing oncogene RAS.
Ferroptosis is a unique iron-dependent form of nonapoptotic cell death. It is triggered by oncogenic RAS-selective lethal small molecule erastin. Acitvation of ferroptosis lead to nonapoptotic destruction of cancer cells.
In BJ-TERT/LT/ST/RASV12 cells, Erastin activated a rapid, oxidative and non-apoptotic cell death process. It exerted lethality in human cancer cells with HRAS, KRAs or BRAF oncogenic mutation involving the RAS-RAF-MEF pathway and acted via modulating VDAC (volatage-dependent anion channels). [1] In HT 1080 cells, Erastin-induced death triggered the cytosolic ROS accumulation and the induced oxidative death was iron dependent. Erastin also inhibited the activity of independent cystine/glutamate antiporter, system xc−. [2]

Applications |
Erastin activates a rapid, oxidative, non-apoptotic cell death process. Erastin exhibits greater lethality in human tumour cells harbouring mutations in the oncogenes HRAS, KRAS or BRAF. Erastin treatment of cells harbouring oncogenic RAS causes the appearance of oxidative species and subsequent death through an oxidative, non-apoptotic mechanism. Treatment of NRAS mutant HT-1080 fibrosarcoma cells with the RSL molecule erastin (10 μM) resulted in a time-dependent increase in cytosolic and lipid ROS beginning |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
