title: Effect of marine glycosides on adenosinetriphosphatase activity.
abstract: Marine glycosides from the sea cucumbers Actinopyga agassizi, Holothuria atra, Bohadschia argus, Cucumaria fraudatrix, Astichopus multifidus and Thelenota ananas inhibit both Na+-K+ ATPase and Mg2+-ATPase of rat brain in vitro. The glycoside-cholesterol complex of these compounds does not influence ATPase activity. Asterosaponins from starfishes Linckia guildingi and Linckia laevigata possess a slight inhibiting effect. The triterpene glycosides from sea cucumbers are more powerful inhibitors than steroidal glycosides from starfishes.
