RSL3-NH2
RSL3-NH2 is a GPX4 inhibitor and ferroptosis inducer. RSL3-NH2 triggers the iron-dependent cell death pathway associated with lipid peroxidation by inhibiting GPX4 activity. RSL3-NH2 exhibits significant cytotoxicity against colorectal cancer cells and effectively induces their ferroptosis. RSL3-NH2 can serve as a ADC payload for synthesizing antibody-drug conjugates (ADC) and be used in colorectal cancer-related research.

The ADC formed by conjugating RSL3-NH2 with a bispecific antibody, namely CDH17 x GUCY2C-RSL3-NH2 ADC, potently inhibits the proliferation of SW1463 and LS1034 cells and induces significant MDA and lipid ROS accumulation, with IC50 values of 4.97 μg/mL and 2.249 μg/mL at 72 h, respectively[1].
CDH17 x GUCY2C-RSL3-NH2 ADC (5 μg/mL; 72 h) exhibits bystander cytotoxicity against CDH17/GUCY2C-negative HT-29 cells when co-cultured with CDH17/GUCY2C-positive SW1463 or LS1034 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:SW1463/HT-29 co-cultures, LS1034/HT-29 co-cultures
-
Concentration:5 μg/mL
-
Incubation Time:72 h
-
Result:Increased bystander killing of CDH17/GUCY2C-negative HT-29 cells in co-culture with positive cells, compared to the control group.
CDH17 x GUCY2C-RSL3-NH2 ADC (1 mg/kg; intravenous injection; once every 5 days; 7 injections in total) induces significant regression of LS1034 colorectal tumors in nude mice and triggers strong ferroptosis (elevated levels of MDA and 4-HNE)[1].
CDH17 x GUCY2C-RSL3-NH2 ADC (1 mg/kg; intravenous injection; once every 5 days; 7 injections total) exhibits favorable safety in double-humanized BALB/c mice, with no hepatotoxicity or organ damage detected[1].

Solvent & Solubility
Ethanol : 100 mg/mL (251.35 mM; Need ultrasonic)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.28 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% EtOH 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.28 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Add each solvent one by one: 10% EtOH 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (6.28 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
