Triheptanoin in acute mouse seizure models.

Abstract

Triheptanoin, the triglyceride of heptanoate, is used to treat certain hereditary metabolic diseases in USA because of its anaplerotic potential. In two chronic mouse seizure models this clear tasteless oil was found to be reproducibly anticonvulsant. Here we investigated the effects of triheptanoin feeding in C3H and CD1 mice using standard acute seizure models. Feeding 30-40% triheptanoin (caloric intake) consistently elevated blood propionyl-carnitines, but inconsistent anticonvulsant effects were observed in the fluorothyl, pentylenetetrazole and 6Hz seizure models. A 2mA consistent increase in the maximal electroshock threshold was found after 3 weeks of 35% triheptanoin feeding (p=0.018). In summary, triheptanoin shows a unique anticonvulsant profile in seizure models, compared to other treatments that are in the clinic. Therefore, despite small and/or inconsistent effects of triheptanoin in acute seizure models, triheptanoin remains of interest as a potential add-on treatment for patients with medically refractory epilepsy.
