RSL3 is the inhibitor of the glutathione (GSH) peroxidase 4, which can inhibit the cysteine/glutamate amino acid transporter system. RSL3 is also a VDAC-independent ferroptosis activator with selectivity for tumor cells bearing oncogenic RAS. RSL3 blocks GSH synthesis with an IC50 of 100 nM. RSL3, that are synthetically lethal with cell lines expressing mutant HRAS and KRAS1.

| 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. |
