Subquinocin

Avis client

Based on 1 Customer Validation

Subquinocin is a tumor suppressor CYLD inhibitor that inhibits USP family deubiquitinases (DUBs) activity of CYLD with an IC₅₀ of 30 μM. Subquinocin enhances the activation of NF-κB and IFN pathways by inhibiting CYLD. Subquinocin promotes RIG-I-mediated activation of IRF3/IRF7 in the interferon pathway. Subquinocin can be used for the research of cancer and neurodegenerative diseases.

In Vitro

Subquinocin potently inhibits the DUB activity of recombinant full-length GST-CYLD with an IC₅₀ of 30 μM by targeting the enzyme's catalytic domain rather than disrupting substrate binding^[1].
Subquinocin inhibits the DUB activity of truncated CYLD's catalytic USP domain with an IC₅₀ of ~65.4 μM, confirming it targets the catalytic region of CYLD^[1].
Subquinocin (25-100 μM) inhibits the DUB activity of CYLD-WT and CYLD-Y940F, but its inhibitory effect is attenuated for CYLD-Y940A, indicating Tyr940 of CYLD is critical for optimal interaction with Subquinocin^[1].
Subquinocin (20) is a selective inhibitor of USP-family deubiquitinating enzymes, with no inhibitory activity against OTU, UCH, JAMM, or MJD/Josephin family DUBs^[1].
Subquinocin (20-40 μM; 2 h) increases non-degradative M1-linked and K63-linked polyubiquitin chains in HeLa cells^[1].
Subquinocin (20-40 μM; 12 h) enhances LUBAC- and TNFα-mediated NF-κB activation in HEK293T cells^[1].
Subquinocin (20-30 μM; 2 h) enhances phosphorylation of key NF-κB signaling components and delays IκBα degradation in TNFα-stimulated HeLa and HEK293T cells^[1].

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: ≥ 3 mg/mL (7.40 mM); Clear solution

This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 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: ≥ 3 mg/mL (7.40 mM); Clear solution

This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 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: ≥ 3 mg/mL (7.40 mM); Clear solution

This protocol yields a clear solution of ≥ 3 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 (30.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
