HGR4113
HGR4113 is an orally active anti-inflammatory/antioxidant agent with improved glucose metabolism. HGR4113 inhibits STAT3 phosphorylation, suppresses Th17 differentiation and IL-17 production, reduces oxidative phosphorylation activity, and promotes the differentiation of regulatory T cells among splenic CD4+ T cells. HGR4113 inhibits LPS (HY-D1056)-induced JNK phosphorylation, production of NO, PGE2 and pro-inflammatory cytokines, expression of iNOS and COX-2, as well as nuclear translocation of NF-κB in macrophages, while induces HO-1 expression by activating nuclear translocation of Nrf2. HGR4113 can be used in the research of inflammatory diseases such as type 2 diabetes and Sjögren's syndrome.

HGR4113 (1-10 μM; 74 h) reduces the viability of stimulated splenocytes in a dose-dependent manner, and inhibits the production of pro-inflammatory cytokines IFNγ, IL-17, TNF-α and IL-6 in splenocytes from C57BL/6 and NOD/ShiLtJ mice stimulated with anti-CD3/anti-CD28 antibodies or LPS[1].
HGR4113 (1-10 μM; 74 h) dose-dependently inhibits Th17 differentiation and pro-inflammatory cytokine production, promotes Treg differentiation, suppresses STAT3 phosphorylation, and reduces OXPHOS activity in purified splenic CD4+ T cells from C57BL/6 mice[1].
HGR4113 (1-10 μM; 98 h) dose-dependently shifts the polarization of B cells from proinflammatory IL-17-producing cells to regulatory IL-10-producing cells, reduces immunoglobulin production, and modulates the mRNA expression of B cell activation- and fibrosis-related genes in purified splenic CD19+ B cells from C57BL/6 mice[1].

HGR4113 (5-20 μM; 4 h) inhibits LPS-induced NF-κB activation in RAW264.7 macrophages in a dose-dependent manner by reducing the phosphorylation level of IκB-α, NF-κB nuclear translocation, and NF-κB DNA-binding activity[2].
HGR4113 (5-20 μM; 3.5 h) dose-dependently inhibits LPS-induced phosphorylation of JNK in RAW264.7 macrophages without affecting the phosphorylation of ERK or p38[2].

HGR4113 (20 μM; 0.5-1.5 h) induces nuclear translocation of Nrf2 in RAW264.7 macrophages, increases nuclear Nrf2 levels and decreases cytoplasmic Nrf2 levels over time[2].
HGR4113 (20 μM; 15 h) induces the expression of HO-1 protein in RAW264.7 macrophages via the ERK MAPK pathway, while the p38 and JNK MAPK pathways exert negative regulatory effects on this induction process[2].
HGR4113 (5-20 μM; 27 h) dose-dependently inhibits LPS-induced PGE2 production in RAW264.7 macrophages, with an IC50 value of 1.64 μM[2].
HGR4113 (5-20 μM; 9 h) dose-dependently inhibits LPS-induced expression of IL-1β, IL-6 and TNF-α mRNA in RAW264.7 macrophages[2].
