Abstract Chlorophyllin (CHL), a chlorophyll-derivative, exhibits several beneficial properties, including antibacterial, antioxidant, and anticancer activities. However, its antibacterial and anti-inflammatory activities against Propionibacterium acnes have not been described. The antibacterial activity of this compound was evaluated in vitro using the broth microdilution method. CHL had an inhibitory effect on the growth of P. acnes (MIC = 100 μM). In a real-time reverse transcriptionpolymerase chain reaction and an enzyme-linked immunosorbent assay, CHL significantly decreased interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) production in a dose-dependent manner, decreasing both mRNA and protein levels for these chemokines in THP-1 cells indicating the anti-inflammatory effects of it. To investigate the molecular mechanisms underlying the anti-inflammatory properties of CHL in THP-1 cells stimulated by P. acnes, we used western blotting to analyze the effect of CHL on activation of the nuclear factor (NF)-κB. CHL inhibited P. acnes-induced IL-8 and MCP-1 production via blockade of NF-κB activation in THP-1 cells. Therefore, based on these results, we suggest that CHL is a useful agent to control the growth of P. acnes involved in acne inflammation and prevent acne.
