In Vitro

QNZ (Compound 11q) has a suppressing effect of the NF-κB mediated-inflammatory response. QNZ inhibits edema formation dose-dependently^[1]. QNZ (EVP4593) reduces the number of lysosomes/autophagosomes and store-operated channel (SOC) currents in Huntington's disease (HD). Normalization of calcium transport within neurons in response to QNZ is expect to reduce pathology manifestation. A number of lysosomes/autophagosomes are evaluated in HD and WT neurons treated with QNZ using transmission electron microscopy (TEM). Incubation with QNZ reduces the number of lysosomes/autophagosomes in HD GABAergic medium spiny (GABA MS)-like neurons (GMSLNs) by almost two-fold (from 0.41±0.04 to 0.23±0.04; p<0.05), while WT neurons are not affected. This observation is confirmed by examining lysosome content by flow cytometry (FC) analysis. The median fluorescence intensity is reduced by 34±6 % in HD GMSLNs upon QNZ treatment (p<0.05)^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (7.01 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (7.01 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (7.01 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol

Cell Assay^[2]

iPSHD22 cells are cultured in K-4 medium in a 96-well black plates with clear flat bottom. Next, cells are treated with chemical compounds (e.g., QNZ 100 nM) for 24 h prior to analysis. Fluorescent assay MultiTox-Fluor Multiplex Cytotoxicity Assay is used to measure simultaneously the relative number of live (viability) and dead (cytotoxicity) cells in each well. Fluorescence is detected by DTX 880 Multimode Microplate Reader. To evaluate the level of cell death (LoCD), the following equation is employed: ([cytotoxicity in a well with cells]-[cytotoxicity in a well without cells])/([viability in a well with cells]-[viability in a well without cells])^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
