First hyperpolarizability of cyclooctatetraene modulated by alkali and alkaline earth metals.

abstract：:Modulation of γ-aminobutyric acid (GABA) levels has been required in various disorders. GABA itself cannot be directly introduced into central nervous system (CNS) because of the blood brain barrier; inhibition of GABA aminotransferase (GABA-AT), which degrades GABA in CNS, has been the target for the modulation of GA...
