N-acetyl-2,3-dehydro-2-Deoxyneuraminic acid (DANA) is an inhibitor of human neuriminidases (sialidases) NEU1-4 (IC50s = 143, 43, 61, and 74 μM, respectively). In vivo, DANA (30 μL of a 5 mM solution) reduces latency to first seizure and increases seizure duration in a rat model of potassium-induced seizures.
