SR12343
Based on 1 Customer Validation
SR12343 is a IKK/NF-κB inhibitor and a mimetic of the NF-κB essential modulator (NEMO)-binding domain (NBD). SR12343 inhibits TNF-α- and LPS-induced NF-κB activation by blocking the interaction between IKKβ and NEMO. SR12343 suppresses LPS-induced acute pulmonary inflammation in mice. SR12343 extends the healthspan of naturally aged and accelerated aging mice. SR12343 can be used for research on inflammatory and degenerative diseases.

Biological Activity
SR12343 (25-150 μM; 30 min) inhibits TNF-α-induced NF-κB activation in HEK293 cells in a dose-dependent manner, with an IC50 of 37.02 μM[2].
SR12343 (50 μM; 30 min) significantly inhibits the expression of COX-2, IL-6 and iNOS in Raw 264.7 macrophages induced by LPS (HY-D1056)[2].
SR12343 (25-50 μM; 1 h) inhibits LPS-induced IL-6 secretion in Raw 264.7 macrophages[2].
SR12343 (25-150 μM; 30 min) dose-dependently disrupts the interaction between endogenous NEMO and IKKβ in Raw 264.7 macrophages, while exerting minimal effect on the binding of NEMO and IKKα[2].
SR12343 (150 μM; 30 min) inhibits the activation of the canonical IKK/NF-κB pathway induced by TNF-α and LPS in Raw 264.7 macrophages, without affecting the JNK or p38MAPK signaling pathways[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
