Renal fibrosis is closely related to chronic inflammation and is under the
control of epigenetic regulations. Because the signaling of transforming growth
factor-?(1) (TGF-?(1)) and tumor necrosis factor-? (TNF-?) play key roles in
progression of renal fibrosis, dual blockade of TGF-?(1) and TNF-? is desired as
its therapeutic approach. Here we screened small molecules showing anti-TNF-?
activity in the compound library of indole derivatives. 11 out of 41 indole
derivatives inhibited the TNF-? effect. Among them, Mitochonic Acid 35 (MA-35),
5-(3, 5-dimethoxybenzyloxy)-3-indoleacetic acid, showed the potent effect. The
anti-TNF-? activity was mediated by inhibiting I?B kinase phosphorylation, which
attenuated the LPS/GaIN-induced hepatic inflammation in the mice. Additionally,
MA-35 concurrently showed an anti-TGF-?(1) effect by inhibiting Smad3
phosphorylation, resulting in the downregulation of TGF-?(1)-induced fibrotic
gene expression. In unilateral ureter obstructed mouse kidney, which is a renal
fibrosis model, MA-35 attenuated renal inflammation and fibrosis with the
downregulation of inflammatory cytokines and fibrotic gene expressions.
Furthermore, MA-35 inhibited TGF-?(1)-induced H3K4me1 histone modification of the
fibrotic gene promoter, leading to a decrease in the fibrotic gene expression.
MA-35 affects multiple signaling pathways involved in the fibrosis and may
recover epigenetic modification; therefore, it could possibly be a novel
therapeutic drug for fibrosis.
