靶点/IC50 |
HSP70 4.6μM (EC50, HeLa cells) |
|
体外研究 |
ML346 is an activator of Hsp70, with an EC50 of 4600nM in HeLa cells. ML346 (10μM) restores proteostasis, restores CFTRmediated 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 (0.5-25μM) 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. |

Kinase Assay |
In brief, HeLa cells are incubated with either DMSO (negative control), the positive controls MG132 (10μM) and lactacystin (6μM) or the PRs A1, A3 and ML346 (F1) for 3 and 6 hours and then harvested. Cells are lysed in homogenization buffer (50mM Tris-HCl, pH7.5, 250mM sucrose, 5mM MgCl2, 2mM ATP, 1mM DTT, 0.5mM EDTA, 0.025% digitonin) for 5 min on ice, and total protein concentration of whole cell extract is determined. 3μg of whole cell extracts are combined with assay buffer (50 mM Tris-HCl, pH 7.5, 40mM KCl, 5mM MgCl2, 0.5mM ATP, 1mM DTT, 0.05 mg/mL BSA) in a black 96-well plate and the reaction is initiated by the addition of a 2× (200μM) fluorogenic peptide substrate Suc-LLVY-AMC. Fluorescence is measured every 10 min using a Synergy H4 multi-mode microplate reader. |

Cell Assay |
HeLa cells are plated at a density of 10,000 cells per well in black 96-well plates in 100μL of DMEM supplemented with 10% FBS and 1% Pen/Strep/Neo. Plates are incubated for 16 hours at 37°C, 5% CO2 and 95% relative humidity before compound addition. 1μL of hit compounds (ML346) in DMSO or DMSO alone are added to the sample or control wells, respectively. Plates are then placed back in the incubator for 24 hours. After incubation, cells are washed 2× with 200μL of PBS and 200μL of a solution of 1μg/mL of calcein AM is added to each well. Cells are then incubated for 45 min at 37°C, 5% CO2 before fluorescence measurement using an Analyst GT multimode reader. Percent cytotoxicity is expressed relative to wells containing cells treated with DMSO only (100%). |
