Marine dinoflagelates from the genus Dynophisis are important producers of Diarrhetic Shellfish Poisoning (DSP) toxins which are responsible for human intoxications. The present work is an approach to study the relative toxicity of DSP toxins effects on Neuro-2a, NG108-15 and MCF-7 cell-lines. Certified standards of okadaic acid (OA), dinophysistoxin-1 (DTX-1) and dinophysistoxin-2 (DTX-2) were used. Our results show that the three toxins exhibit similar cytotoxicity in Neuro-2a and NG108-15 cell lines. Conversely, MCF-7 cells were the least sensitive to these toxins. DTX-1 displayed the most toxic effect in the three tested cell lines.
