In the HTRF-based LUBAC-mediated ubiquitination assay with Petit-LUBAC. HOIPIN-1 (0.9-120 μM) exhibits an increased inhibitory activity with a a longer preincubation time in the reaction buffer. The IC50 values are 26 μM, 26 μM, 26 μM, and 3.926 μM, at 1h, 3h, 6h and 24 h, respectively.
The coexpression of the LUBAC subunits in HEK293T cells increases the intracellular amounts of linear polyubiquitin, HOIPIN-1 (1-30 μM) dose dependently suppressed the production of intracellular linear polyubiquitin in LUBAC-expressing HEK293T cells.
HOIPIN-1 (30-100 μM; 30-60 mins) inhibits IL-1β-induced NF-κB activation and decreases the phosphorylation of IKKα/β, p105, and p65 in hela cells.
HOIPIN-1 (10-100 μM) inhibits the expression of NF-κB target genes such as ICAM1 and TNF-α in IL-1β-induced hela cells in a dose-dependent manner.
