Picrotoxinin

17617-45-7C15H16O6292.287 g/mol

A picrotoxane sesquiterpenoid that is 3a,4,5,6,7,7a-hexahydro-1H-indene-3,7-dicarboxylic acid which is substituted at positions 3a, 6, and 7a by methyl, isopropenyl, and hydroxy groups, respectively; in which the double bond at position 2-3 has been epoxidised; and in which the carboxy groups at positions 3 and 7 have undergone γ-lactone formation by O-alkylation to positions 4 and 5, respectively. A component of picrotoxin. — ChEBI
