| Ryanodine Usage And Synthesis |
| 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). | | Chemical Properties | white to off-white solid | | Uses | Insecticide. | | Uses | Ryanodine is a potent inhibitor of Ca2+ release from sarcoplasmic reticulum with potential application towards the treatment of huntingtons disease. | | Definition | ChEBI: An insecticide alkaloid isolated from South American plant Ryania speciosa. | | 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). | | References | Rogers et ai., J. Amer. Chem. Soc., 70, 3086 (1948)
