The toxicity of ryanodine (1) and 9,21-didehydroryanodine (2) (the principal active ingredients of the botanical insecticide ryania) to adult female house Γies (Musca domestica L.) is attributable to binding to the ryanodine receptor (ryr) and thereby disrupting the Ca2`-release channel. These ryano

β¦ Synopsis
The naturally-occurring ionophore X206, originally isolated for its antibacterial activity, also exhibits broad insecticidal and acaricidal activity. This summary reports structure/activity studies with X206 and 34 derivatives as well as mode of action studies. Although many compounds showed promising insecticidal activity, it was only of a contact activity nature ; furthermore, the acute LD 50 of the compounds in rats precluded further development of these compounds.
