L-α-Aminoadipic Acid is a glutamine synthetase inhibitor.
Glutamine synthetase is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine.
In vitro: Previous study found that DL- and L-alpha-aminoadipic acid (alpha-AA) were specific gliotoxins in vitro. HPLC analysis of cultures incubated with D- or L-alpha-AA and DL-[14C]-alpha-AA autoradiograms conducted in the presence of D- or L-alpha-AA suggested a stereospecificity of astroglial L-alpha-AA uptake. Both the uptake of alpha-AA by astrocytes and alpha-AA-induced gliotoxicity were sodium dependent [1]. Another study found that the L-isomer of alpha aminoadipate was able to competitively inhibit the transport protein, whereas the D-isomer of alpha aminoadipate was ineffective. Moreover, it was found that L-alpha aminoadipate was a competitive inhibitor of both glutamine synthetase, and gamma-glutamylcysteine synthetase. In constrast, the D-isomer of alpha aminoadipate was a far weaker inhibitor of either enzyme [2].
In vivo: Animal study showed that L-a-aminoadipic acid could lower the levels of endogenous extracellular kynurenic acid in the hippocampus in a dose-dependent fashion), though the effect of L-a-aminoadipic acid seemed to be less pronounced than its reduction of de novo produced kynurenic acid [3].
Clinical trial: So far, no clinical study has been conducted.
