Decarbamoylsaxitoxin
Decarbamoylsaxitoxin is a sodium channel inhibitor that blocks the influx of sodium ions through the membranes of excitable nerves and skeletal muscle cells, thereby preventing the formation of action potentials. Decarbamoylsaxitoxin is an acidic hydrolysis product of saxitoxin, and its toxic effects on mice are identical to those of saxitoxin. Decarbamoylsaxitoxin inhibits veratridine- and ouabain-induced swelling and lysis of mouse neuroblastoma cells by blocking Na+ channels. Decarbamoylsaxitoxin can be used in studies related to paralytic shellfish poisoning.

Activité biologique
Decarbamoylsaxitoxin (200-1000 pg/well, 3 nM to 300 μM; 8-24 hr) inhibits ouabain/veratridine-induced cell lysis in mouse neuroblastoma cells (ATCC no. CCL 131) with a mean relative toxicity of 42.6% compared to US FDA saxitoxin standard[2].
Decarbamoylsaxitoxin (110 μg/mL; 5 min boiled in 0.1 N or 1.0 N HCl) remains stable (toxicity unchanged) after boiling for 5 min in either 0.1 N or 1.0 N HCl, as measured in mouse neuroblastoma cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
