- Decarbamoylsaxitoxin, abbreviated as dcSTX, is a neurotoxin which is naturally produced in dinoflagellate. DcSTX is one of the many analogues of saxitoxin (STX). Saxitoxin is a tricyclic alkaloid compound, which has multiple structural related neurotoxins. One of those related neurotoxins is neosaxitoxin (NSTX) in which the nitrogen at position 2 is not bound to a hydrogen, but to a hydroxyl group. Another toxic analogue of saxitoxin is gonyautoxin (GTX). The difference between GTX and STX is that on the carbon at position 11, a hydrogensulfate is bound. Between dcSTX, NSTX and GTX, dcSTX is the one which varies most from saxitoxin. In dcSTX there is a double bond between carbons 2 and 3, while there is a single bond in STX. This also results in that the double-bonded N to carbon number 3 in STX, is a single bound NH2 in dcSTX. Another difference between decarbamoylsaxitoxin and saxitoxin is that the amino-carbonyl-oxy-methyl group at position 1 in STX, is only a CH2OH group in dcSTX. Even though there are slight differences between all saxitoxin-related compounds, all those saxitoxins are neurotoxins which affect the sodium channels. When in contact with one of the saxitoxins it can cause a severe illness, which is known as paralytic shellfish poisoning (PSP). (en)
