Anti-inflammatory agent 74 (B5) is an anti-inflammatory agent that can inhibit NO, IL-6, and TNF-alpha, with IC50 values of 10.88 µM and 4.93 µM for NO and IL-6, respectively. Anti-inflammatory agent 74 alleviates acute lung injury (ALI) by regulating inflammatory mediators and inhibiting the MAPK and NF-kappaB signaling pathways[1].
