Description
LS-102 is a selective E3 ubiquitin ligase synoviolin (Syvn1) inhibitor. LS-102 inhibits the autoubiquitination of synoviolin with an IC 50 of 35 µM. LS-102 has the potential for rheumatoid arthritis treatment.In VitroLS-102 inhibits proliferation of RSCs with an IC 50 of 5.4 µM. ?\nLS-102 suppresses proliferation of rheumatoid synovial cells (RSCs) in a Syvn1-dependent manner. LS-102 suppresses polyubiquitination of target proteins of Syvn1, including nuclear factor erythroid 2-related factor 2 (NRF2), V247M α-sarcoglycan mutant, and PGC-1β. LS-102 inhibits E3 ligase activity of Synoviolin (Syvn1). MCE has not independently confirmed the accuracy of these methods. They are for reference only.
