Product Description
Cardiotonic glycoside which presents a bufadienolide-steroid structure. Besides ouabain (Prod. No. ALX-350-066), from the class of cardenolides hellebrin is the second unique water soluble cardiotonic glycoside. Extremely potent inhibitor of Na+/K+-ATPase  (sodium pump) blocking the active efflux of Na+ and reuptake of K+ of this membrane enzyme. Shows a positive inotropic effect by increasing the intracellular Ca2+ concentration. Strong immunosuppressor inhibiting T cell activity with much higher potency than cortisol or cyclosporin A (Prod. No. ALX-380-002). Induces caspase-dependent apoptosis.

Product Description
Immunosuppressant. Potent inhibitor of NF-κB activation in T cells, with an almost complete inhibition at 200nM. Suppresses cytokine production (IFN-γ, TNF-α, IL-2 and IL-4) and inhibits NF-AT in peripheral blood T cells at concentrations that do not impair NF-κB and AP-1 activities. In contrast to the immunosuppressant cyclosporin A (Prod. No. ALX-380-002), rocaglamide does not inhibit calcineurin phosphatase activity. Induces apoptosis.
