Targeting Hsp90α to inhibit HMGB1-mediated renal inflammation and fibrosis.

ABSTRACT: Renal fibrosis, a terminal manifestation of chronic kidney disease, is characterized by uncontrolled inflammatory responses, increased oxidative stress, tubular cell death, and imbalanced deposition of extracellular matrix. 5,2'-Dibromo-2,4',5'-trihydroxydiphenylmethanone (LM49), a polyphenol derivative synthesized by our group with excellent anti-inflammatory pharmacological properties, has been identified as a small-molecule inducer of extracellular matrix degradation. Nonetheless, the protective effects and mechanisms of LM49 on renal fibrosis remain unknown. Here, we report LM49 could effectively alleviate renal fibrosis and improve filtration function. Furthermore, LM49 significantly inhibited macrophage infiltration, pro-inflammatory cytokine production and oxidative stress. Interest
