In vitro mechanistic study
Anti-inflammatory compounds identified by UHPLC-MS analysis.
Researchers at the University of Mississippi's National Center for Natural Products Research used ultrahigh-performance liquid chromatography mass spectrometry to identify the specific anti-inflammatory compounds present in ZL01.
Four classes of bioactive compounds were identified as contributing to anti-inflammatory activity: hydroxylated fatty acids, chlorophyll-derived pheophorbides, carotenoids, and glycoglycerolipids.
Pheophorbide a was identified as the most potent compound. It inhibited inducible nitric oxide synthase (iNOS), a key enzyme in the body's healthy inflammatory response, at a concentration of 0.24 µM. It also demonstrated inhibition of NF-κB, a central transcription factor in inflammatory signaling.
