[Definition]

ChEBI: An insecticide alkaloid isolated from South American plant Ryania speciosa.
[Uses]

Insecticide.
[Biological Activity]

Potent inhibitor of Ca 2+ release from sarcoplasmic reticulum (IC 50 values are 10 and 2.8 nM in skeletal and cardiac muscle respectively).
[Description]

Ryania insecticide is the ground stem wood of the tropical tree Ryania speciosa Vahl., and it contains over a dozen of several structurally related alkaloids. Nowadays, this botanical preparation is of minor importance, but one of its major ingredients, ryanodine, is a widely used pharmacological tool in studies of the calcium release channels in sarcoplasmic reticulum membranes of skeletal and cardiac muscle of both insects and mammals (11,12).
[storage]

Desiccate at -20°C
