We investigated the effects of flumazenil, aminophylline, and ephedrine on the excitatory amino acid transporter type 3 (EAAT3) activity and the interaction with propofol.
EAAT3 was expressed in the Xenopus oocytes.
L-Glutamate-induced membrane currents were measured using the two-electrode voltage clamp at various drug concentrations.
Oocytes were preincubated with protein kinase C- (PKC-) activator, or inhibitor, and phosphatidylinositol 3-kinase (PI3K) inhibitor.
To study the interaction with propofol, oocytes were exposed to propofol, propofol + aminophylline, or ephedrine.
Aminophylline and ephedrine significantly decreased EAAT3 activity.
Aminophylline (95 μM) and ephedrine (1.19 μM) significantly decreased Vmax, but not Km of EAAT3, for glutamate.
The phorbol 12-myristate-13-acetate-induced increase in EAAT3 activity was abolished by aminophylline or ephedrine.
The decreased EAAT3 activities by PKC inhibitors (staurosporine, chelerythrine) and PI3K inhibitor (wortmannin) were not significantly different from those by aminophylline or ephedrine, as well as those by PKC inhibitors or PI3K inhibitor + aminophylline or ephedrine.
The enhanced EAAT3 activities induced by propofol were significantly abolished by aminophylline or ephedrine.
Aminophylline and ephedrine inhibit EAAT3 activity via PKC and PI3K pathways and abolish the increased EAAT3 activity by propofol.
Our results indicate a novel site of action for aminophylline and ephedrine.
