PG - 149711 LID - S0006-291X(24)00247-X [pii] LID - 10.1016/j.bbrc.2024.149711 [doi] AB - Two series of urolithin derivatives, totally 38 compounds, were synthesized. Their anti-inflammatory activity was investigated by detecting the inhibitory effects on the expression of TNF-alpha in bone marrow-derived macrophages (BMDMs), showing that 24 of 38 ones reduced the expression of TNF-alpha. Compound B2, the ring C opened derivative of urolithin B with a butoxycarbonyl substitution in ring A, showed the strongest inhibitory activity compared with that of indomethacin. Furthermore, B2 treatment decreased the expression of pro-inflammatory factors IL-1beta, IL-6, iNOS and COX-2. Mechanically, the anti-inflammatory effect of B2 was related to the inhibition of NF-kappaB signaling pathway. These results clearly illustrated that B2 hold potential for application as an anti-inflammatory agent. The present study provided a viable approach to modify the gut metabolites for anti-inflammatory drug development. CI - Copyright (c) 2024 Elsevier Inc. All rights reserved.
