产品描述 Description

T-817MA [1-{3-[2-(1-Benzothiophen-5-yl)ethoxy] propyl}-3-azetidinol maleate] is a newly synthesized agent for Alzheimer's disease (AD) treatment with neuroprotective effects against toxicity from amyloid-β peptide (Aβ) and actions promoting neurite outgrowth[1].

T-817MA was pretreated for 24 h,T-817MA significantly prevented neuronal damage caused by H2O2 treatment at 0.1 and 1 uM[1]. T-817MA at 0.1 and 1microM attenuated the neurotoxicity in a dose-dependent way and the protective effect required pretreatment for more than 8h. T-817MA attenuated SNP-induced decrease in mitochondrial transmembrane potential[5].

T-817MA (8.4 mg/kg/day; p.o.) hippocampal neurogenesis was significantly increased and spatial learning disabilities were improved in rats treated with aβ[2]. T-817MA (10 or 20 mg/kg) or vehicle was administered for 14 days. Administration of T-817MA at 20 mg/kg ameliorated Prepulse inhibition (PPI) deficits and completely reversed the decrease in the number of PV-positive GABAergic neurons in rats given MK-801[3]. T-817MA (0.21 or 0.07 mg/ml, p.o.) is effective in ameliorating sensorimotor gating deficits caused by chronic PCP treatment, possibly via neuroprotective actions[4]. T-817MA prevented the progression of motor deficit and the loss of spinal cord motor neurons in P301L mice[6]. Sustained oral administration of T-817MA significantly reduced the extent of auditory threshold shifts and outer hair cell loss, indicating that T-817MA attenuates the intense pressure-induced cochlear damage that accompanies inner ear barotrauma via antioxidative activity[7].

T-817MA [1-{3-[2-(1-Benzothiophen-5-yl)ethoxy] propyl}-3-azetidinol maleate] 是一种新合成的阿尔茨海默病 (AD) 治疗剂,具有神经保护作用β-淀粉样肽 (Aβ) 的毒性和促进神经突生长的作用[1].

T-817MA 预处理 24 小时后,T-817MA 在 0.1 和 1 uM[1] 时显着防止 H2O2 处理引起的神经元损伤。 0.1 和 1microM 的 T-817MA 以剂量依赖的方式减弱神经毒性,保护作用需要预处理 8 小时以上。 T-817MA 减弱了 SNP 诱导的线粒体跨膜电位降低[5]。

在用 aβ[2] 处理的大鼠中,T-817MA（8.4 毫克/千克/天；口服）显着增加海马神经发生并改善空间学习障碍。 T-817MA（10 或 20 mg/kg）或载体给药 14 天。在给予 MK-801[3] 的大鼠中,以 20 mg/kg 的剂量施用 T-817MA 可改善前脉冲抑制 (PPI) 缺陷并完全逆转 PV 阳性 GABA 能神经元数量的减少。 T-817MA（0.21 或 0.07 mg/ml,口服）可有效改善由慢性 PCP 治疗引起的感觉运动门控缺陷,可能是通过神经保护作用[4]。 T-817MA 阻止了 P301L 小鼠运动缺陷的进展和脊髓运动神经元的丢失[6]。持续口服 T-817MA 可显着降低听阈偏移和外毛细胞丢失的程度,表明 T-817MA 通过抗氧化活性减轻内耳气压伤伴随的强压诱导的耳蜗损伤[7].

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

Neuron/Glia Coculture

Preparation Method

T-817MA( Edonerpic maleate (T-817 maleate)) was added to the cocultures at concentrations of 0 (control), 0.01, 0.1, and 1 M, and the cells were subsequently incubated for 5 min or 24 h. H2O2 was then added to the coculture at a concentration of 100 M, and the cells were incubated for another 24 h. For the normal group, the preparations were maintained in the medium with neither T-siM nor H2O2. Neuronal cell viability was quantified by measuring the MAP2 immunoreactivity

Reaction Conditions

0, 0.01, 0.1, and 1 µM;5min or 24h

Applications

The 100 µM H2O2 treatment greatly reduced the number of surviving neurons in the culture. When T-817MA was pretreated for 24 h, T-817MA significantly prevented this neuronal damage at 0.1 and 1 µM. Conversely, a brief (5 min) pretreatment with T-817MA, followed by its continuous presence with H2O2, did not rescue the H2O2-treated neurons from death.
Animal experiment [2]:

Animal models

Wistar rats (7 weeks)

Preparation Method

Rats were divided into five groups: vehicle (n= 11), Aβ infusion control (n= 10), Aβ infusion + high-dose T-817MA (8.4 mg/kg) (n= 11), Aβ infusion + low-dose T-817MA (0.84 mg/kg) (n= 9) and Aβ infusion + donepezil (0.5 mg/kg) (n= 7).

Dosage form

0.84/8.4 mg/kg/day, p.o.

Applications

Rats given Aβ infusions for 10 weeks displayed spatial memory impairments and a decrease in neurogenesis compared with those infused with vehicle. Treatment of the Aβ-infused rats with T-817MA (8.4 mg/kg/day;p.o.) significantly increased hippocampal neurogenesis and ameliorated spatial learning impairments.
