Manoalide

Manoalide is a calcium channel blocker. It has antibiotic, analgesic and anti-inflammatory effects and is found in some sponges, including the West Pacific species Luffariella variabilis.^[1] Its functions are made possible by the permanent blockage of phospholipase A2 and C^[2] with lysine residues. This could be made possible through the functional groups incorporated in gamma-hydroxybutenolide, alpha-hydroxydihydropyran and the trimethylcyclohexenyl. The gamma-hydroxybutenolide ring is present in the reaction between manoalide and phospholipase A2, the hemiacetal in alpha-hydroxydihydropyran is needed for permanent binding and hydrophobic trimethylcyclohexenyl ring makes it possible for non-bonded interactions to interact between manoalide and phospholipase A2 to strengthen the reaction. ^[3] Due to its potential of permanent inhibition, it was made possible for it to take part in oral cancer^[4] and hepatitis C^[5] research.
