Nodularin, Nodularia spumigena

Description:

Nodularin is a potent cyclic peptide toxin produced by the cyanobacterium Nodularia spumigena, commonly found in brackish and freshwater environments. It is primarily known for its hepatotoxic effects, which can lead to liver damage in humans and animals upon exposure. Nodularin is structurally similar to microcystins, another group of cyanobacterial toxins, and functions as an inhibitor of protein phosphatases, particularly protein phosphatase 1 and 2A, disrupting cellular signaling pathways. This disruption can result in various toxicological effects, including cell death and tumor promotion. Nodularin is typically found in aquatic ecosystems during algal blooms, which can be triggered by nutrient enrichment, particularly nitrogen and phosphorus. Its presence in water bodies poses significant risks to aquatic life and human health, especially through contaminated drinking water or seafood. Monitoring and management of cyanobacterial blooms are essential to mitigate the risks associated with nodularin and other cyanotoxins.

Nodularin

CAS: 118399-22-7

Nodularin is an indolic alkaloid that has been identified as a potent inhibitor of the mitogen-activated protein kinase (MAPK) pathway. It has been shown to inhibit the growth factor-β1 and platelet-derived growth factor (PDGF)-induced proliferation of vascular smooth muscle cells in vitro. Nodularin can be used to detect MAPK activation by using Western blotting with phosphorylated extracellular signal regulated kinase 1/2 (ERK1/2) antibodies. In addition, nodularin can be used for the detection of intracellular targets, such as cyclic AMP response element binding protein (CREB), which is activated by CREB-binding protein and phosphatidylinositol 3-kinase.
