MCC950: NLRP3-inflammasome inhibitor

MCC950 is a potent and selective inhibitor of the NLRP3 (NOD-like receptor (NLR) pyrin domain-containing protein 3) inflammasome.

The NLRP3 inflammasome is an innate immune sensor that upon assembly activates caspase-1 and mediates the processing and release of IL‑1β.

MCC950 blocks the release of IL‑1β induced by NLRP3 activators, such as ATP, MSU and nigericin, by preventing oligomerization of the inflammasome adaptor protein ASC (apoptosis-associated speck-like protein containing the a CARD) [1,2].

In research models of inflammation, such as cryopyrin associated periodic syndromes (CAPS) and myocardial infarction, it effectively inhibited NLRP3-induced IL-1β production [1-3]. Importantly, MCC950 does not inhibit the AIM2, NLRC4 or NLRP1 inflammasomes [1].
