The NLRP3 inflammasome mediates the production of proinflammatory cytokines and initiates inflammatory cell death. Although NLRP3 is essential for innate immunity, aberrant NLRP3 inflammasome activation contributes to a wide variety of inflammatory diseases. Understanding the pathways that control NLRP3 activation...

Herein, we report a new synthetic route from (S)-pyroglutaminol to (+)-lactacystin, a potent inhibitor of the 20S proteasome. The photoinduced intermolecular C(sp(3))-H alkynylation and intramolecular C(sp(3))-H acylation chemo- and stereoselectively constructed the tetra- and trisubstituted carbon centers, respectively. The obtained...
