Biological target:
Erdosteine inhibits lipopolysaccharide (LPS)-induced NF-κB activation.
In vitro activity:
Cell viability, pro-inflammatory cytokines and the degradation of ECM biomarkers were tested to determine the effects of ER (erdosteine) at 10, 20, and 40 μM doses on IL-1β-induced rat chondrocytes for 24 h in vitro. In vivo, intra-articular injections of 50 μl of 100 mg/ml ER twice a week for 8 weeks. The results showed ER significantly suppressed the expressions of IL-1β-induced the production of inflammatory factors in a dose-dependent pattern (4.30-fold decrease in COX-2, p < 0.05; 4.77-fold decrease in iNOS, p < 0.05 at 40 μM in protein levels). Reference: Eur J Pharmacol. 2020 Apr 15;873:172925. https://pubmed.ncbi.nlm.nih.gov/31958453/
In vivo activity:
Erdosteine at 80 mg/kg reversed the deleterious effects of ISO and normalized myocardium. Erdosteine showed anti-inflammatory, antiapoptotic, and antioxidant activities through inhibition of MAPK and Nrf-2/HO-1 pathways. To conclude, erdosteine was found protective in ISO-induced myocardial necrosis through MAPK and Nrf-2/HO-1 pathway.
