NP3-146 sodium

NP3-146 sodium is a NLRP3 inflammasome inhibitor through locking the NACHT domain of NLRP3. NP3-146 sodium shows potent inhibitory activity against IL-1β release with an IC50 value of 0.171 μM in LPS/Nigericin-stimulated BMDM cells. NP3-146 sodium regulates the levels of cleaved Caspase-1 and cleaved IL-1β in cell supernatants. NP3-146 sodium can be used for the research of inflammatory diseases.
