ML346

产品介绍

ML346是 Hsp70 和 HSF-1 活性的激活剂，针对 Hsp70 的 EC₅₀ 为 4.6 μM。ML346 恢复构象疾病模型中的蛋白质折叠，而没有明显的细胞毒性或缺乏特异性。ML346 诱导了热休克反应 (HSR) 的基因和蛋白质效应子的特异性增加，包括伴侣蛋白如 Hsp70，Hsp40 和 Hsp27。

生物活性

ML346 is an activator of Hsp70 expression and HSF-1 activity, with an EC₅₀ of 4.6 μM for Hsp70. ML346 restores protein folding in conformational disease models, without significant cytotoxicity or lack of specificity. ML346 induces specific increases in genes and protein effectors of the heat shock response (HSR), including chaperones such as Hsp70, Hsp40, and Hsp27.

体外研究

ML346 is an activator of Hsp70, with an EC₅₀ of 4600 nM in HeLa cells. ML346 (10 μM) restores proteostasis, restores CFTR-mediated iodide conductance, and enhances the correct folding of proteins expressed in two different cellular compartments. ML346 (Compound F1) induces multiple responses and strongly induces Hsp70, the oxidative stress response genes (HO1 and GCLM), and a 2.5-fold upregulation of BiP in WT MEF cells. ML346 (0.5-25 μM) exhibits cytoprotective effects in cells after a 35 min severe heat shock, and also causes a two-fold protection from H₂O₂-induced apoptosis.

体内研究

ML346 suppress the aggregation of polyQ35 in a C. elegans model, suggesting the probe has efficacy in modifying protein aggregation and associated toxicity.

储备液的保存方式和期限：-80°C, 6 months; -20°C, 1 month。-80°C 储存时，请在 6 个月内使用，-20°C 储存时，请在 1 个月内使用。

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

1.

请依序添加每种溶剂： 10% DMSO 90% (20% SBE-β-CD in saline)
Solubility: ≥ 1.25 mg/mL (4.59 mM); Clear solution

此方案可获得 ≥ 1.25 mg/mL (4.59 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 12.5 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。
将 2 g 磺丁基醚 β-环糊精加入 5 mL 生理盐水中，再用生理盐水定容至 10 mL，完全溶解，澄清透明
