HOIPIN-8 is a potent inhibitor of linear ubiquitin chain assembly complex (LUBAC) with IC50 of 11 nM. HOIPIN-8 is an analogue of HOIPIN-1. Compared with HOIPIN-1, it displays 255 times the petit-LUBAC inhibitory ability. It inhibits LUBAC and TNF-α-mediated NF-κB activation. It is HOIPIN- 10 times and 4 times the inhibitory effect. HOIPIN-8 is a promising tool for studying the cellular functions of LUBAC.

Biological Activity


ln Vitro At an IC50 value of 100 μM, HOIPIN-8 (0-100 μM; 72 hours) exhibits nearly little cytotoxicity against A549 cells[1]. HOIPIN-8 (0–10 μM; 24 hours) inhibits NF-κB activation more than ten times more than HOIPIN-1, which has an IC50 value of 0.42 μM in HEK293T cells [1]. With an IC50 value of 11.9 μM, HOIPIN-8 (0-30 μM) is 4 times more successful than HOIPIN-1, which transfects cells with the NF-κB luciferase reporter gene for 18 hours before transfecting them with 10 ng/mL TNF-α for 6 hours. It is also more effective than HOIPIN-1 at reducing the expression of NF-κB target genes (including ICAM1 and IL-6) that are triggered by IL-1β [1].

Solubility Data


Solubility (In Vitro) DMSO :~100 mg/mL (~219.12 mM)
Solubility (In Vivo) Solubility in Formulation 1: 1.25 mg/mL (2.74 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 1.25 mg/mL (2.74 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: 1.25 mg/mL (2.74 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
