  • Highly potent Na+/K+-ATPase inhibitor, blocking the active efflux of Na+ and reuptake of K+.
  • Water soluble cardiotonic glycoside from the class of bufadienolides (with 2-pyrone ring).
  • Inhibits cancer cell growth in vitro. Shown to induce caspase-dependent apoptosis, reducing MDR resistance and the rate of mitochondrial oxidative phosphorylation in cancer cells.
  • Inotropic by increasing the intracellular Ca2+ concentration.
  • Immunosuppressive and anti-inflammatory agent that inhibits allogeneic T cell activation with much higher potency than cortisol or cyclosporin A.
  • Anti-seizure activity in pentylenetetrazole (PTZ)-induced epileptical seizures.
