CS47
Based on 1 Customer Validation
CS47 is a Thioredoxin Reductase 1 (TRXR1) inhibitor and ferroptosis inducer. CS47 binds non-covalently to sites between the FAD and NADPH pockets of TRXR1. CS47 drives glutathione depletion, lipid reactive oxygen species accumulation, HMOX1-dependent iron overload, and selective cytotoxicity in lung cancer cells. CS47 can be used for the research of lung cancer.

Description
In Vitro
CS47 (48 h) selectively reduces viability of KRAS-WT and EGFR-MUT human lung cancer cells in 2D culture with IC50 values of 6.74 µM and 6.78 µM, respectively, while showing much lower potency against KM lung cancer cells (IC50 = 24.22 µM) and normal IMR90 fibroblasts (IC50 = 54.85 µM)[1].
CS47 (48 h) induces potent cell death in 3D spheroids of KRAS-WT (H661, H522) and EGFR-MUT (HCC827) human lung cancer cells, but not in KM (H460) or KRAS-WT H522 cells with KM overexpression[1].
CS47 (2 μM; 24 h) induces significant lipid peroxidation in KRAS-WT human lung cancer cells (H1993, H1395), but not in KRASG12C human lung cancer cells (H157, A549)[1].
CS47 (2 μM; 24 h) alters lipid homeostasis in KRAS-WT H522 human lung cancer cells, inducing enrichment of ferroptosis-associated PUFA-containing phospholipids and accumulation of LPC and PUFA-containing TG[1].
CS47 (24 h) induces transcriptomic reprogramming in KRAS-WT and EGFR-MUT human lung cancer cells, downregulating lipid biosynthesis and selenoprotein genes while upregulating ferroptosis-related genes involved in antioxidant response, iron metabolism, and GSH homeostasis; HMOX1 is universally upregulated across all genotypes[1].

-
Animal Model:NCG (Nod Scid IL-2Rγ-/-) mice (9 weeks) injected with H661 and H661-HMOX1 cells[1]
-
Dosage:3 mg/kg
-
Administration:i.p.; every 3 days; 25 days
-
Result:Produced a significant anti-tumor effect, with tumor volumes remaining far lower than vehicle controls throughout the 25-day treatment period.
Increased intratumoral C11-BODIPY oxidation, a marker of lipid peroxidation.
Induced accumulation of polyunsaturated fatty acid-containing phospholipids and triacylglycerols, consistent with ferroptosis.
Did not cause significant weight loss in mice.
Exhibited no marked leukopenia or neutropenia observed.
Exhibited even more pronounced anti-tumor effect in H661-HMOX1-GFPlo xenografts.
Increased intratumoral accumulation of 4-Hydroxynonenal, a marker of ferroptosis, in both parental and HMOX1-overexpressing xenografts.
