Biological Activity

Description

AOA (Aminooxyacetic acid) hemihydrochloride is an inhibitor of aminobutyrate aminotransferase involved in amino acid and polyamine metabolism. AOA hemihydrochloride is also a CBS (cystathionine β-synthase) inhibitor.

Targets

GABA-T ^[1]

Malate-aspartate shuttle ^[1]

In vitro

Aminooxyacetic acid (AOAA) is a malate-aspartate shuttle inhibitor, leading to decreased intracellular ATP levels and altering cell cycle and increasing apoptosis and necrosis of C6 glioma cells, without affecting the survival of primary astrocyte cultures. AOAA also decreases the glycolytic rate and the levels of extracellular lactate and pyruvate, without affecting the mitochondrial membrane potential of C6 cells. Aminooxyacetic acid can selectively inhibit the proliferation of breast cancer cells^[1].

In vivo

Aminooxyacetic acid suppresses the growth of breast adenocarcinoma in athymic mice^[1]. AOAA is much less toxic in rats than in mice^[2].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines C6 glioma cells Concentrations 0.1, 0.25, 0.5, 1, 5 mM Incubation Time 24 h Method C6 glioma cells are plated into 24-well or 12-well cell culture plates at the initial density of 1 × 10⁶ cells/mL in Dulbecco's Modified Eagle's Medium containing 4500 mg/L D-glucose, 584 mg/L L-glutamine, and 1% penicillin and streptomycin, supplemented with 10% fetal bovine serum. The cells are maintained in a 5% CO2 incubator at 37℃. Cell survival is assessed 24 h after AOAA treatment by intracellular LDH assay.
Animal Study:^{^[2]}	Animal Models female Wistar rats Dosages 15 to 100 mg/kg Administration i.p. or s.c.
