Solasonine is a glycoalkaloid that is found in Solanum plants of the family Solanaceae. Solasonine is a poisonous chemical compound when used at high levels.  It is a glycoside of solasodine. Glycoalkaloids such as Solasonine have various applications including pharmacology, cancer treatments and even a role as a pesticide.
High levels of glycoalkaloids are  toxic to humans due to their ability to disrupt cell-membrane function. There is a loss of membrane integrity which puts the cell at risk for apoptosis (cell death) due to the ability of any chemical coming into contact with the cell.
Solasonine was one component of the unsuccessful experimental cancer drug candidate Coramsine.
