Toxic amino acids

group of stereoisomers

chemical compound

natural marine acid present in some seaweed

Ethionine is a non-proteinogenic amino acid structurally related to methionine, with an ethyl group in place of the methyl group.

chemical compound

Muscazone is a toxic chemical compound. It is an amino acid found in European fly agaric mushrooms.

Mimosine or leucenol is a toxic non-protein amino acid chemically similar to tyrosine. It occurs in some Mimosa spp. (including M. pudica) and all members of the closely related genus Leucaena.

L-(+)-(S)-Canavanine is a non-proteinogenic amino acid found in certain leguminous plants. It is structurally related to the proteinogenic α-amino acid L-arginine, the sole difference being the replacement of a methylene bridge ( unit) in arginine with an oxa group (i.e., an oxygen atom) in canavanine. Canavanine is accumulated primarily in the seeds of the organisms which produce it, where it serves both as a highly deleterious defensive compound against herbivores (due to cells mistaking it for arginine) and a vital source of nitrogen for the growing embryo. The related L-canaline is similar

chemical compound

β-Methylamino--alanine, or BMAA, is a non-proteinogenic amino acid produced by cyanobacteria. BMAA is a neurotoxin. Its potential role in various neurodegenerative disorders is the subject of scientific research.

Alanosine (also called SDX-102) is a substance that has been studied for the treatment of pancreatic cancer. It is an antimetabolite. It is used as one of a few experimental treatments for patients with deadly pancreatic cancer when the main chemotherapeutic treatment regimen of gemcitabine is no longer useful.

'''S-Aminoethyl--cysteine, also known as thialysine''', is a toxic analog of the amino acid lysine in which the second carbon of the amino acid's R-group (side chain) has been replaced with a sulfur atom.

Caramboxin (CBX) is a neurotoxin that is found in star fruit (Averrhoa carambol). The fruit was used as traditional Chinese medicine, for treating fever, cough, and asthma, and it is believed to have more beneficial effects.

-Canaline (IUPAC name 2-amino-4-(aminooxy)butyric acid)) is a non-proteinogenic amino acid. The compound is found in legumes that contain canavanine, from which it is produced by the action of arginase. The most common-used source for this amino acid is the jack bean, Canavalia ensiformis.
