Anti-inflammatory agent 35 (compound 5a27) is an orally active curcumin analogue with anti-inflammatory activity. Anti-inflammatory agent 35 blocks mitogen-activated protein kinase (MAPK) signaling and p65 nuclear translocation of NF-kB. Anti-inflammatory agent 35 also inhibits yellow neutrophil infiltration and pro-inflammatory cytokine production. Anti-inflammatory agent 35 significantly attenuates lipopolysaccharide (LPS)-induced acute lung injury (ALI) in vivo
In Vitro
Anti-inflammatory agent 35 (compound 5a27) (10 μM; 30 min) inhibits the production of proinflammatory cytokines (IL-6, TNF-α) induced by LPS (0.5 μg/mL; 24 h) without cytotoxicity in mouse primary macrophages (MPMs). Anti-inflammatory agent 35 inhibits the production of IL-6, TNF-α with IC50s of 2.23 μM and 2.40 μM, respectively. Anti-inflammatory agent 35 (10 μM; 30 min) significantly inhibits LPS-induced activation in RAW 264.7 mouse macrophages. And it markedly inhibits p-p38 and p-ERK, decreases IκB level, indicating the suppression of MAPK and NF-κB signaling. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell Line: RAW 264.7 mouse macrophages Concentration: 10 μM Incubation Time: 30 min; followed by incubation with 0.5 μg/mL LPS for another 30 min Result: Decreased the phosphorylation of p38 and ERK. And down-regulated IκB (inhibitor of NF-κB), inhibits the transcription of TNF-α, IL-6, IL-1β, ICAM-1.
In Vivo
Anti-inflammatory agent 35 (compound 5a27) (50 mg/kg; po; single dose, monitored 0-25 min) has a better bioavailability than curcumin (HY-N0005) . Anti-inflammatory agent 35 (10 mg/kg; ip; once daily for 1 week) improves LPS-induced ALI by inhibiting inflammation in mice model .
