Abstract The effect of thiamin and its phosphate esters on dopamine (DA) release was examined in the rat striatum using an in vivo microdialysis. Intrastriatal administration of thiamin triphosphate (TTP) or thiamin diphosphate (TDP) induced DA release, but thiamin monophosphate (TMP) or thiamin did not show any change. In the absence of Ca2+ in the perfusate, TTP did not increase the DA release. omega-Conotoxin did not decrease the TTP-dependent DA release. These findings suggest that, in contrast to TMP and thiamin, TTP and TDP may play a specific role in DA release from nerve terminals.
