M464, a non-steroidal anti-inflammatory compound, is a potent and orally active NLRP3 inflammasome inhibitor. M464 inhibits pyroptosis and hinders the activation of downstream Caspase-1 expression and the release of IL-1β by impeding ASC oligomerisation and curtailing ROS production. M464 exhibits protective effects against acute lung and liver injury in mice. M464 can be used for the research of NLRP3-related inflammatory diseases.

IC50 & Target[1]

NLRP3 inflammasome

 

In Vitro

M464 (3-12 μM) inhibits the expression of marker proteins associated with NLRP3 inflammasome activation (IL-1β and Caspase-1), and restrains the production of intracellular ROS and the formation of ASC oligomers in J774A.1 and THP-1 cells[1].
M464 (3-12 μM; 1 h) inhibits pyroptosis in macrophages triggered by the NLRP3 inflammasome stimulator in J774A.1 and THP-1 cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
