Yessotoxin（Cat No.:M017956） is a marine toxin produced by certain dinoflagellates, such as Protoceratium reticulatum and some species of Gonyaulax. It is commonly associated with harmful algal blooms and can accumulate in shellfish, posing health risks to humans who consume contaminated seafood. Structurally, yessotoxin is a complex polyether compound, known for its ability to disrupt cellular calcium balance. Although initially classified among the diarrhetic shellfish poisons, subsequent research has shown that it does not cause diarrhea but can lead to other toxic effects, such as heart damage in animal studies. Its mechanism involves the inhibition of phosphodiesterases, leading to altered cell signaling.
