Ryanoid
From Wikipedia, the free encyclopedia
Ryanoids are a class of insecticides which share the same mechanism of action as the alkaloid ryanodine. Ryanodine is a naturally occurring insecticide isolated from Ryania speciosa.
Ryanoids include natural chemicals which are closely related to ryanodine, such as ryanodol and 9,21-didehydroryanodol,[1] and also chemically distinct synthetic compounds such as chlorantraniliprole (Rynaxypyr) and cyantraniliprole.
Ryanoids exert their insecticidal effect by interacting with ryanodine receptors, a type of calcium channel. This causes loss of muscle function leading to paralysis and death.
Ryanoids include:
