半岛bd体育手机客户端 介绍
AA147 是一种内质网 ( ER) 蛋白稳态调节剂。AA147 可通过选择性激活未折叠蛋白反应的 ATF6臂以及激活 NRF2氧化应激反应来促进对神经元细胞氧化损伤的保护，并防止内皮屏障功能失调。AA147 还可重新平衡 XBP1s在体内的表达，并诱导运动神经元存活基因的表达并保护脊柱运动神经元。
生物活性

AA147 is aendoplasmic reticulum (ER)proteostasis regulator. AA147 promotes protection against oxidative damage in neuronal cells and prevents endothelial barrier dysfunction by activatingATF6arm (selectively) of the unfolded protein response (UPR) and theNRF2oxidative stress response. AA147 can rebalancesXBP1sexpression in vivo, and also induces survival motor neuron (SMN) expression and spinal motorneuron (MN) protection[1][2][3][4].
体外研究
(In Vitro)

AA147 (20-0.078 μM (dilution in half); 6 or 16 h) protects against glutamate-induced oxidative toxicity in HT22 cells by decreasing the reactive oxygen species (ROS)-associated damage[1].
AA147 (10 μM; 16 h) induces NRF2-dependent upregulation of oxidative stress response genes in HT22 cells[1].
AA147 (10 μM; 16 h) covalently modifies KEAP1 to promote NRF2 activation in HT22 cells[1].
AA147 (5, 10, 15 μM; 4, 8, 16, 24, 48 h) induces ATF6 activation and upregulates phosphorylation of cofilin in BPAEC[2].
AA147 (10 μM; 24 h) reduces LPS-induced endothelial barrier disruption in BPAEC[2].
AA147 (5, 10 μM; 135 h) enhances lung endothelial barrier integrity[2].

Cell Viability Assay[1]

Cell Line: HT22 cells
Concentration: 0.078, 0.156, 0.312, 0.625, 1.25, 2.5, 5, 10, 20 μM
Incubation Time: 6 or 16 h (pre-incubation)
Result: Showed dose-dependent increases in the viability of glutamate-treated HT22 cells when pretreated with AA147 for 6 or 16 h prior to the glutamate challenge (addition concurrently with the glutamate challenge did not improve the viability of glutamate-treated cells).
Reduced ROS accumulation in cells when pre-incubation of 16 h.

Cell Viability Assay[1]

Cell Line: HT22 cells
Concentration: 10 μM
Incubation Time: 16 h
Result: Significant increased the expression of genes associated with antioxidant activity in neuronal models, including prolactins and glutathione transferases.
Activated NRF2 through a mechanism involving metabolic activation and covalent KEAP1 protein modification.

Cell Viability Assay[2]

Cell Line: BPAEC
Concentration: 5, 10 μM
Incubation Time: 135 h
Result: Decreased permeability of cells by activation of ATF6.

Western Blot Analysis[2]

Cell Line: BPAEC
Concentration: 5, 10, 15 μM
Incubation Time: 4, 8, 16, 24, 48 h
Result: Significantly induced ATF6 activation and upregulated cofilin phosphorylation (in a concentration-dependent manner).

Western Blot Analysis[2]

Cell Line: BPAEC
Concentration: 10 μM
Incubation Time: 24 h
Result: Reduced LPS-induced cATF6 suppression (Fig.5A) and VE-cadherin phosphorylation.
Inhibited cofilin and MLC2 activation in the inflamed cells.
Inhibited LPS-induced hyperpermeability in BPAEC.
体内研究
(In Vivo)

AA147 (intrathecal injection; single for 3 days) can rebalance XBP1s expression in severe SMA-like mice by activating ATF6, and also induce survival motor neuron expression and spinal motorneuron protection[3].
