STAMBP-IN-1 是 STAMBP去泛素酶的小分子抑制剂，能中断 STAMBP-Ub-NALP7 的相互作用。在 Toll 样受体 (TLR) 激动后，STAMBP-IN-1 能够降低炎性小体底物 NALP7 的蛋白水平，抑制 IL-1b 释放。STAMBP- in -1 抑制了 STAMBP 裂解重组蛋白 di-Ub 的活性，IC₅₀ 为 0.33 mM。

STAMBP-IN-1 is a small-molecule inhibitor of STAMBP deubiquitinase, and interrupts STAMBP-Ub-NALP7 interaction. STAMBP-IN-1 decreases protein level of its inflammasome substrate NALP7 and suppresses IL-1b release after Toll-like receptor (TLR) agonism. STAMBP-IN-1 inhibits the activity of STAMBP to cleave recombinant di-Ub with an IC 50 value of 0.33 mM.

Solid

STAMBP-IN-1 (0.1-10 μM; 6 h) exhibits the most potent ability to selectively decrease NALP7 abundance as well as endogenous NALP7 abundance in THP-1 cells, but not NALP6.
STAMBP-IN-1 (0.01-100 μM; 37 ℃; 2 h) inhibits cleavage of K63-linked di-Ub (200 nM) to mono-Ub by purified recombinant STAMBP (25 nM) in a concentration dependent manner.
STAMBP-IN-1 (0.01-10 μM; 37 ℃; 60 min) blocks STAMBP mediated deubiquitination of Ub-NALP7 in vitro in a concentration-dependent manner.
STAMBP-IN-1 exhibits toxicity against THP-1 cells with an IC50 of 106 μg/mL.
has not independently confirmed the accuracy of these methods. They are for reference only.
