nigericin

Nigericin is an antibiotic derived from Streptomyces hygroscopicus that acts as a K+/H+ ionophore, promoting K+/H+ exchange across mitochondrial membranes. Nigericin can be an NLRP3 activator that causes the release of IL-1β as a NALP3-dependent manner. N

Nigericin sodium salt is an antibiotic, an NLRP3 activator, and a cationic ion carrier. Nigericin sodium triggers the activation of the NALP3 inflammasome, which inhibits Golgi function and suppresses the growth of Gram-positive bacteria.

NLRP3-IN-NBC6 is a potent, selective NLRP3 inflammasome inhibitor with IC50 of 574 nM. NLRP3-IN-NBC6 acts independently of Ca 2+. NLRP3-IN-NBC6 inhibits Nigericin -induced inflammasome activation in THP-1 cells and Imiquimod -induced IL-1β release from LPS-primed bone marrow-derived macrophages (BMDMs) [1].

ADS032 (BT-032) is an NLRP1 and NLRP3 inhibitor with anti-inflammatory activity,, inhibits the activation of NLRP1 and NLRP3, inhibits Nigericin-induced IL-1β production, and can be used to study respiratory inflammation or infection.

A-130A is a polycyclic polyether compound belonging to the nigericin group of antibiotics generated by Streptomyces hygroscopicus strain.

NLRP3-IN-9 (INF-4E) is an inhibitor of NLRP3 ATPase and caspase-1. NLRP3-IN-9 acts by irreversibly trapping thiol nucleophiles, which prevents both ATP- and nigericin-triggered pyroptosis of human THP-1 cells in a time- and concentration-dependent manner.

NLRP3/AIM2-IN-3 is a unique molecule that inhibits NLRP3 and AIM2 inflammasome activation in a species-specific manner. It has an IC50 value for cell lysis of 0.077 ± 0.008 μ M. NLRP3/AIM2-IN-3 is a potent inhibitor of NLRP3 and AIM2 inflammasome-dependent cell lysis with an IC50 value for cell lysis of 0.077 ± 0.008 μ M. NLRP3/AIM2-IN-3 inhibits LPS/nigericin NLRP3/AIM2-IN-3 inhibits LPS/nigericin-stimulated cell lysis in THP-1 macrophages with an IC50 value of 0.077 ± 0.008 μM. NLRP3/AIM2-IN-3 interferes with the interaction of NLRP3 or AIM2 with the bridging protein ASC, inhibiting oligomerization of ASC.
