Proteasome inhibitors list
Webb16 maj 2024 · The 26S proteasome is a multisubunit protease that degrades the substrate into small peptides in an ATP-dependent manner ( 2, 3 ). The prote-asome has three peptidase activities, including ( i) chymotrypsin-like, ( ii) trypsin-like, and ( iii) peptidylglutamyl-peptide hydrolase activities ( 2 ). Webb5 sep. 2024 · NLRP3 inflammasome activation plays a critical role in inflammation-related disorders. More small-molecule entities are needed to study the mechanism of NLRP3 inflammasome activation and to validate the efficacy and safety of the NLRP3 pathway. Herein, we report the discovery of an orally bioavailable proteasome inhibitor NIC-0102 …

Webb31 aug. 1999 · In contrast to peptide aldehyde proteasome inhibitors, epoxomicin does not inhibit nonproteasomal proteases such trypsin, chymotrypsin, papain, calpain, and cathepsin B at concentrations of up to 50 μM. In addition, epoxomicin is a more potent inhibitor of the chymotrypsin-like activity than lactacystin and the peptide vinyl sulfone … WebbReactive sulfur species (RSS) have emerged as key regulators of protein quality control. However, the mechanisms by which RSS contribute to cellular processes are not fully understood. In this study, we identified a novel function of RSS in preventing parthanatos, a non-apoptotic form of cell death that is induced by poly (ADP-ribose) polymerase-1 …
