Apigenin 7-O-glucuronide is a flavonoid that has been found in J. sigillata and has diverse biological activities.1,2,3,4 It inhibits matrix metalloproteinase-3 (MMP-3), MMP-8, MMP-9, and MMP-13 (IC50s = 12.87, 22.39, 17.52, and 0.27 μM, respectively).1,2,3,4 Apigenin 7-O-glucuronide also inhibits protein tyrosine phosphatase 1B (PTP1B), acetylcholinesterase (AChE), and aldose reductase with IC50 values of 7.14, 62.96, and 107.1 µM, respectively.2,3 It inhibits LPS-induced production of nitric oxide, prostaglandin E2 , and TNF-α in RAW 264.7 cells when used at a concentration of 100 µM.4 Apigenin 7-O-glucuronide (5 or 10 mg/kg) improves survival in a mouse model of septic shock induced by LPS.
