Abstract: | The hypothesis that the brain GABA level increase which is induced by a sodium dipropyl acetate treatment arises either through inhibition of succinic semialdehyde dehydrogenase (SSADH), or through inhibition of GABA transaminase by succinic semialdehyde (SSA), has been considered. It appeared that in vivo brain GABA level increase cannot be attributed to SSADH inhibition, and that SSA is not a GABA precursor. It has been shown that SSA is neither in vivo nor in vitro a GABA-transaminase inhibitor. 4-hydroxybenzaldehyde, a potent SSADH inhibitor did not increase GABA level at a dosage which induces a 99% inhibition of SSADH. |
