γ-Aminobutyric acid (4-Aminobutyric acid) 是成年哺乳动物大脑中主要的抑制性神经递质，能够与离子移变GABAA受体和促代谢GABAB受体结合发挥作用。γ-Aminobutyric acid 能够阻断中枢神经系统的特定信号，并带来镇静效果。
| 生物活性 | γ-Aminobutyric acid (4-Aminobutyric acid) is a major inhibitory neurotransmitter in the adult mammalian brain, binding to the ionotropic GABA receptors (GABAAreceptors) and metabotropic receptors (GABABreceptors. γ-Aminobutyric acid shows calming effect by blocking specific signals of central nervous system[1][2]. |

体外研究
(In Vitro) | γ-Aminobutyric acid (30 μM) depolarizes cortical progenitor cells (E16 cells), results an inward current in ventricular zone (VZ) cells, and induces DNA synthesis inhibition, with half-maximal response concentration of 5 μM[3].
Cortical plate (cp) neurons expresses glutamic acid decarboxylase (GAD), γ-Aminobutyric acid (1-5 μM; 18 h) stimulates the motility and arrests the migration of cp cells, while the chemotropic signal is involved G-protein activation[4].
γ-Aminobutyric acid activates GABAAreceptors, causing cell cycle arrest in S phase and limiting growth[5].
Cell Migration Assay[4] | Cell Line: | Cortical plate (cp) neurons | | Concentration: | 1-5 μM | | Incubation Time: | 18 hours | | Result: | Promoted motility via G-protein activation and arrested attractantinduced migration via GABAA receptor-mediated depolarization. |

体内研究
(In Vivo) | γ-Aminobutyric acid (33.95, 102.25, 306.75 mg/kg; p.o.; single dose) can enhance the sleep of mice[6].
γ-Aminobutyric acid (1, 2, 4 mg/kg/d; p.o.; 30 d) alleviates anxiety and restored food utilization rate in rats, with impairment induced by Di(2-ethylhexyl) phthalate (DEHP) exposure[7].
| Animal Model: | Pathogens free (SPF) Bagg’s albino (Balb/c) mice (18–20 g, 8 weeks old)[6] | | Dosage: | 33.95, 102.25, 306.75 mg/kg | | Administration: | Oral gavage; single dose; 20 mL/kg administration; measured in an hour | | Result: | Prolonged the sleep duration, increased sleep rate, and shorten the sleep latency more effectively. |
| Animal Model: | Sprague-Dawley rat indued byDEHP(HY-B1945) (500 mg/kg)[7] | | Dosage: | 1, 2, 4 mg/kg | | Administration: | Oral gavage; combined administration; for 30 consecutive days | | Result: | Reduced the levels of nitric oxide and nitric oxide synthase in rats treated with DEHP. |
