生物活性 | ONX-0914 (PR-957) TFA is a selective inhibitor of low-molecular mass polypeptide-7 (LMP7), the chymotrypsin-like subunit of the immunoproteasome. ONX-0914 TFA blocks cytokine production and attenuates progression of experimental arthritis. ONX-0914 TFA is a noncompetitive irreversible inhibitor of the mycobacterial proteasome (Ki=5.2 μM). ONX-0914 TFA reactivates latent HIV-1 through p-TEFb activation mediated by HSF-1. | ||||||||||||||||
