SW203668
Based on 1 Customer Validation
SW203668 is an irreversible stearoyl CoA desaturase (SCD) inhibitor with an IC50 of 54 nM. SW203668 covalently binds and inhibits SCD, depletes unsaturated fatty acids, and triggers cell death in sensitive cells. SW203668 requires demethylation by CYP4F11 to form its active SCD-inhibiting form; differential CYP4F11 expression drives selective cytotoxicity. SW203668 exerts cytotoxicity toward CYP4F11-expressing non-small cell lung cancer (NSCLC) cells and spares CYP4F11-lacking NSCLC cells. SW203668 inhibits tumor growth in immunodeficient mice bearing CYP4F11-expressing NSCLC xenografts and spares mouse skin sebocytes. SW203668 can be used for the research of non-small cell lung cancer.

In Vitro
SW203668 is selectively cytotoxic to 4 human NSCLC cell lines (H2122, H460, and 2 others) with IC50 values of 0.022-0.116 μM, and shows no toxicity to 8 other human NSCLC cell lines at concentrations up to 10 μM[1].
SW203668 inhibits SCD activity in H2122 cell microsomes with an IC50 of 0.054 μM[1].
SW203668 is activated by CYP4F11 to crosslink and inhibit SCD, conferring cytotoxicity to previously insensitive H1155 NSCLC cells[1].

Solvent & Solubility
In Vitro:
DMSO : 50 mg/mL (128.38 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
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% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.42 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 DMSO 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.
