Gamma-aminobutyric acid is a gamma-amino acid that is butanoic acid with the amino substituent located at C-4. It has a role as a signalling molecule, a human metabolite, a Saccharomyces cerevisiae metabolite and a neurotransmitter. It is a gamma-amino acid and a monocarboxylic acid. It derives from a butyric acid. It is a conjugate acid of a gamma-aminobutyrate. It is a tautomer of a gamma-aminobutyric acid zwitterion.|The most common inhibitory neurotransmitter in the central nervous system.|Vigabatrin is a GABA derivative that is used in combination with other agents as therapy of refractory complex partial seizures and as monotherapy for infantile spasms. Vigabatrin is associated with a paradoxical decrease in serum enzyme levels during therapy, explained by its direct inhibition of aminotransferase activity. Vigabatrin has not been convincingly linked to cases of clinically apparent liver injury, but was linked to a fatal case of Reye syndrome in a child with severe developmental delay.|Granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF) are glycosylated polypeptides that induce an increase in the proliferation and maturation of white blood cells including neutrophils and monocytes-macrophages. Recombinant forms of these colony stimulating factors are used to treat severe neutropenia in patients receiving cancer chemotherapy or undergoing hematopoietic cell transplantation. Recombinant forms include filgrastim (G-CSF) and sargramostim (GM-CSF), both of which are commercially available for therapy of severe neutropenia and bone marrow failure. Neither filgrastim nor sargramostim have been linked to serum enzyme elevations during therapy or to clinically apparent liver injury.|Gamma-Aminobutyric Acid is a naturally occurring neurotransmitter with central nervous system (CNS) inhibitory activity. Gamma-aminobutyric acid (GABA), converted from the principal excitatory neurotransmitter glutamate in the brain, plays a role in regulating neuronal excitability by binding to its receptors, GABA-A and GABA-B, and thereby causing ion channel opening, hyperpolarization and eventually inhibition of neurotransmission.
