A Stereocontrolled Synthesis of (+)-Saxitoxin [PDF]
Journal of the American Chemical Society, 2011 A concise stereoselective total synthesis of (+)-saxitoxin is described. A silver(I)-initiated hydroamination cascade constructs the bicyclic guanidinium ion core from a alkynyl bisguanidine. This sequence creates two C-N bonds, one C-O bond, and three rings and forms a single stereoisomer in a single synthetic transformation.

Bacterial Production of Saxitoxin
Agricultural and Biological Chemistry, 1988 A bacterium was isolated from the homogenate of Protogonyaulax tamarensis cells cultured in T1 medium containing antibiotics. The culture broth after centrifugation, to remove the cells, and the bacterial cells contained a toxin that could kill mice with signs similar to those of poisoning by paralytic shellfish toxins or tetrodotoxin. The toxin in the

Integrating scFv into xMAP Assays for the Detection of Marine Toxins
Toxins, 2016 Marine toxins, such as saxitoxin and domoic acid are associated with algae blooms and can bioaccumulate in shell fish which present both health and economic concerns.

Characterization of Benzoyl Saxitoxin Analogs from the Toxigenic Marine Dinoflagellate Gymnodinium catenatum by Hydrophilic Interaction Liquid Ion-Chromatography-Tandem Mass Spectrometry [PDF]
, 2017 The chain-forming marine dinoflagellate Gymnodinium catenatum Graham has a remarkable capacity to produce a wide array of neurotoxic alkaloids associated with Paralytic Shellfish Poisoning (PSP). More than a decade ago, a completely new group of benzoyl

Sophisticated sperm allocation in male fowl [PDF]
, 2003 When a female is sexually promiscuous, the ejaculates of different males compete for the fertilization of her eggs; the more sperm a male inseminates into a female, the more likely he is to fertilize her eggs.

Guanadinium toxins and their interactions with voltage-gated sodium ion channels [PDF]
, 2017 Guanidinium toxins, such as saxitoxin (STX), tetrodotoxin (TTX) and their analogs, are naturally occurring alkaloids with divergent evolutionary origins and biogeographical distribution, but which share the common chemical feature of guanidinium ...

The envenomation of general physiology throughout the last century. [PDF]
, 2017 Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Environmental Toxicology, EarlyView.ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...
