Synthesis and evaluation of novel heteroaromatic substrates of GABA aminotransferase
摘要:
Two principal neurotransmitters are involved in the regulation of mammalian neuronal activity, namely, gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, and L-glutamic acid, an excitatory neurotransmitter. Low GABA levels in the brain have been implicated in epilepsy and several other neurological diseases. Because of GABA's poor ability to cross the blood-brain barrier (BBB), a successful strategy to raise brain GABA concentrations is the use of a compound that does cross the BBB and inhibits or inactivates GABA aminotransferase (GABA-AT), the enzyme responsible for GABA catabolism. Vigabatrin, a mechanism-based inactivator of GABA-AT, is currently a successful therapeutic for epilepsy, but has harmful side effects, leaving a need for improved GABA-AT inactivators. Here, we report the synthesis and evaluation of a series of heteroaromatic GABA analogues as substrates of GABA-AT, which will be used as the basis for the design of novel enzyme inactivators.

Genomic DNA of reproductive cells, including sperm and other cells important in reproduction, are stained and optionally sorted by targeting oligomeric polyamides capable of fluorescence to target DNA sequences and then sorting the cells, for example, by fluorescence activated cell sorting or other cell separation techniques.
