Tabersonine is a selective, orally active NLRP3 inhibitor. Tabersonine directly binds to the NACHT domain of NLRP3, inhibiting its ATPase activity and oligomerization, thereby blocking ASC spot formation and caspase-1 activation, and reducing the release of pro-inflammatory cytokines such as IL-1β. Tabersonine also inhibits K63-linked ubiquitination of TRAF6, blocking NF-κB, PI3K/Akt, and p38 MAPK signaling pathways. Tabersonine can inhibit inflammatory responses, induce apoptosis of liver cancer cells through mitochondrial pathways and death receptor pathways, reduce mitochondrial membrane potential, promote cytochrome c release, and activate caspase proteins. Tabersonine is mainly used in the study of NLRP3-driven inflammatory diseases (such as acute lung injury, sepsis, peritonitis) and tumors such as liver cancer.

In Vitro

Tabersonine (0.78-25 μM; 24 h) inhibits the cell viability of human liver cancer cells SMMC-7721, HepG2 and human normal liver cells HL-7702, with a stronger inhibitory effect on liver cancer cells^[1].
Tabersonine (6.25-25 μM; 24 h) induces apoptosis of human liver cancer cells SMMC-7721, upregulates the expression of Bax, cleaved-caspase-3, and cleaved-PARP proteins, and downregulates the expression of Bcl-2 protein^[1].
Tabersonine (12.5-25 μM; 24 h) arrests the cell cycle of SMMC-7721 cells at the G0/G1 phase, and downregulates the expression of CDK4 and Cyclin D1 proteins^[1].
Tabersonine (25 μM; 6 h, 12 h, 24 h) inhibits the mRNA and protein expressions of NLRP3, ASC, cleaved-caspase-1, and IL-1β in SMMC-7721 cells^[1].
Tabersonine (6-30 μM; 18 h) induces apoptosis in HepG2 cells, resulting in mitochondrial function impairment, and PI3K/Akt pathway inhibition^[2].
Tabersonine inhibits NLRP3-mediated IL-1β production in BMDM cells with an IC₅₀ of 0.71 μM^[3].

The protein expression of Bax, cleaved-caspase-3 and cleaved-PARP was up-regulated, while the protein expression of Bcl-2 was down-regulated.

In Vivo

Tabersonine (10-40 mg/kg; intraperitoneal injection; once a day; 30 days) reduces lung tissue pathological damage, inhibits neutrophil infiltration, reduces MPO activity and TNF-α, IL-6, and IL-1β levels in the mouse LPS-induced acute lung injury model^[1].
Tabersonine (25, 50 mg/kg; oral gavage; once a day; 3 weeks) significantly inhibits tumor growth in the nude mouse HepG2 liver cancer xenograft model, induces the expression of cleaved Caspase-3 in tumor tissues and promotes cell apoptosis^[2].
Tabersonine (10 mg/kg; gavage; 3 times a day; 48-120 h) inhibits NLRP3 inflammasome activation, reduces IL-1β release and inflammatory cell infiltration in the mouse LPS-induced acute lung injury and Alum-induced peritonitis models; and increases the 48-hour survival rate of mice to 60% in the Escherichia coli-induced sepsis model^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
