Liproxstatin-1 is a potent inhibitor of ferroptosis, a non-apoptotic form of cell death characterized by iron-dependent accumulation of lethal lipid reactive oxygen species (ROS). Liproxstatin-1 suppressed ferroptosis in human cells and in an ischaemia/reperfusion-induced tissue injury model in mice. Knockout of glutathione peroxidase 4 (Gpx4) Has been shown to cause cell death by ferroptosis. Liproxstatin-1 was able to suppress ferroptosis in Gpx4 knock-out mice.

| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

| MMRi62
MMRi62 is a ferroptosis inducer targeting MDM2-MDM4 (negative regulator of the oncogene p53), which induces ferroptosis accompanied by an increase in reactive oxygen species (ROS) and lysosomal degradation of ferritin heavy chain (FTH1).MMRi62 displays p53-independent apoptosis activity and induces autophagy in pancreatic ductal adenocarcinoma (PDAC) cells. MMRi62 shows p53-independent pro-apoptosis activity and induces autophagy in pancreatic ductal adenocarcinoma (PDAC) cells.) In addition, MMRi62 caused proteasomal degradation of mutant p53 and was active in vivo in an in situ xenograft PDAC mouse model characterized by high-frequency mutations in KRAS and TP53. |
