Thioperamide reduces intracellular calcium in mouse brain synaptosomes.
Intracellular calcium regulation is vital for cells, especially for neurons; raised levels are associated with cytotoxicity and neuronal death. In this report, we present the first experimental evidence showing a concentration-dependent reduction of free calcium in the mouse brain synaptosomes by thioperamide (THP), an H3 receptor antagonist. This is interesting in view of the recent reports on the anticonvulsant and cognition facilitating effects of THP. A neuroprotective potential of THP is suggested.
