Bioactivity

Elesclomol (STA-4783) is a potent copper ionophore and promotes copper-dependent cell death (cuproptosis). Elesclomol specifically binds ferredoxin 1 (FDX1) α2/α3 helices and β5 strand. Elesclomol inhibits FDX1-mediated Fe-S cluster biosynthesis. Elesclomol is an oxidative stress inducer that induces cancer cell apoptosis. Elesclomol is a reactive oxygen species (ROS) inducer. Elesclomol can be used for Menkes and associated disorders of hereditary copper deficiency research[1][2][3][4].

Invitro

Elesclomol (STA-4783) binds the FDX1 α2/α3 helices and β5 strand, but does not bind the paralog protein FDX2. Elesclomol-Cu(II) is an FDX1 neo-substrate. FDX1 protein binds and reduces the elesclomol-Cu(II) complex[1]. Elesclomol-Cu (1:1 ratio) (40 nM) for only 2 hours results in a 15- to 60-fold increase in intracellular copper levels that triggered cell death more than 24 hours later in ABC1 cells[1]. The addition of copper to elesclomol at a 1:1 molar ratio prior to treatment significantly reduces cell viability when cells are grown in glycolytic (glucose media) conditions[2]. Elesclomol (200 nM; 18 hours) treatment increases the number of early and late apoptotic cells in HSB2 cells. Elesclomol induces apoptosis in cancer cells through the induction of oxidative stress[3].Elesclomol significantly inhibits the cell viability of SK-MEL-5, MCF-7, and HL-60 cells with IC50 values of 110 nM, 24 nM and 9 nM, respectively[5].
