生物活性

製品説明 Elesclomol (STA-4783) is a novel potent oxidative stress inducer that elicits pro-apoptosis events among tumor cells. Phase 3.Elesclomol specifically binds ferredoxin 1 (FDX1) α2/α3 helices and β5 strand and inhibits FDX1-mediated Fe-S cluster biosynthesis.Elesclomol (STA-4783) is a potent copper ionophore and can be used in the research of copper-dependent cell death (cuproptosis).
in vitro

Elesclomol significantly induces the expression of heat shock stress response genes and metallothionein genes, a signature transcription profile indicative of oxidative stress in Hs294T cells. Elesclomol (100 nM) rapidly induces Hsp70 RNA levels with a 4.8-fold increase at 1 hour and a 160-fold increase at 6 hours in Ramos Burkitt's lymphoma B cells in consistent with the intracellular ROS content which increases by 20% as early as 0.5 hour and 385% at 6 hours, and the induction of Hsp70 can be blocked by antioxidants N-acetylcysteine (NAC) and Tiron pretreatment. Elesclomol increases the number of early and late apoptotic cells with 3.7- and 11-fold through the induction of oxidative stress, which can be completely blocked by NAC, while having little effect on normal cells. [1] Elesclomol significantly inhibits the cell viability of SK-MEL-5, MCF-7, and HL-60 with IC50 of 110 nM, 24 nM and 9 nM, respectively. [2] Elesclomol induces copper-dependent ROS generation and cytoxicity in yeast. Instead of working through a specific cellular protein target, Elesclomol interacts with the electron transport chain (ETC), a biologically coherent set of processes occurring in the mitochondrion, to generate high levels of ROS within the organelle and consequently cell death. [3]
in vivo

Although Elesclomol (25-100 mg/kg) as a single agent shows no antitumor activity in nude mouse xenograft models of human breast cancers (MDA435, MCF7 and ZR-75-1), lung cancer (RER) or lymphoma (U937), Elesclomol substantially enhances the efficacy of chemotherapeutic agents such as paclitaxel in these models, both in terms of tumor regression and extended survival of mice.

プロトコル(参考用のみ)

細胞アッセイ 細胞株 Hs294T, HSB2, and Ramos
濃度 Dissolved in DMSO at a concentration of 10 mM, final concentrations ~500 nM
反応時間 18, or 24 hours
実験の流れ

Cells are treated with various concentrations of Elesclomol for 18 or 24 hours. The level of intracellular ROS is monitored using the DCFDA probe, which emits a green fluorescence on oxidation. Cell death is determined by flow cytometry of cells double stained with Annexin V/FITC and propidium iodide (PI) using a Vybrant Apoptosis assay kit.
動物実験 動物モデル Female CD-1 nude mice bearing established MDA435 breast cancer xenograft tumors
投薬量 ~100 mg/kg
投与方法 Intravenous injection
