产品描述
氨氧基乙酸半盐酸盐（Aminooxyacetic Acid Hemihydrochloride, AOAA Hemihydrochloride）是GABA转氨酶抑制剂（Ki= 9.16μM），诱导大脑内GABA累积[1]。AOAA还能抑制胱硫醚β合成酶（CBS）和胱硫醚γ裂解酶（CSE）活性，IC50分别是8.5μM和1.1μM[2]。AOAA（100mg/kg）降低GABA转氨酶活性，不会对谷氨酸脱羧酶（GAD）活性产生影响，并且能提高大鼠大脑所有区域的GABA水平[3]。AOAA（13mg/kg）还能减低小鼠大脑的GABA转氨酶活性，以及增加GABA水平。AOAA抑制3-巯基丙酸、马钱子碱和戊四氮唑诱导的小鼠癫痫发作，ED50s分别是53、130和85mg/kg，然而，AOAA在烟囱试验中呈现神经毒性（ED50= 62mg/kg），且对小鼠有致命性（LD50=105mg/kg）[4]。AOAA还普遍用作苹果酸-天冬氨酸穿梭（Malate-aspartate shuttle, MAS）抑制剂，抑制C6胶质细胞的胞内ATP水平和改变细胞周期，还能减少糖酵解速率、胞外乳酸和丙酮酸水平[5]。

PMID: 36249744; PMCID: PMC9561130. 体外研究（In Vitro Assay）： 细胞类型（Cell type）：Bone marrow-derived macrophages (BMMs) 配制方法（Formulation）：AOAA was dissolved in phosphate-buffered saline at a concentration of 20 mM at−20°C, and further diluted to working concentration using culture medium. 实验方法（Cell viability assay）：BMMs (7 × 103cells/well) were seeded into 96-well plates and cultured in complete α-MEM containing 30 ng/ml M-CSF andAOAA (0, 0.1, 0.2, 0.3, 0.4, and 0.5 mM) for 48 and 96 h.CCK-8 was used to measure cell viability. 体内研究（In Vivo Assay）： 动物模型（Animal Model）：Ovariectomized mouse model 实验方法（Assay）：Twenty-four C57BL/6J mice (females, 11-week-old) were randomly divided into four groups containing six mice each: sham (injected PBS), OVX + PBS (injected PBS), OVX + estrogen (injected 100 ng/kg E2), and OVX + AOAA (injected 5 mg/kg AOAA). The mice were anesthetized with 3% tribromoethanol; next, both the ovaries of all mice except those in the sham group were surgically excised.A week later, the mice received intraperitoneal injections of PBS, E2, or AOAA every 2 days for 6 weeks. |

Same volume of NS was used as control.L5-6DRGs from LDH rats after AOAA treatment were collected either for measurement of NaV1.7 and NaV1.8 expression or for patch clamping studies. |
