ABSTRACT
The phytochemical investigation of Broussonetia kazinoki roots led to the isolation of ten compounds, including six flavonoids (1–6), two lignans (7 and 8), and two coumarins (9 and 10) by comparing their 1H and 13C NMR spectra with reference values. To the best of our knowledge, compounds 9 and 10 were isolated from this plant for the first time. Among the ten isolates, compounds 2, 4, and 6 exhibited inhibitory effects against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in macrophage RAW264.7 cells with IC50 values of 11.98, 10.16, and 24.06 μM, respectively. Furthermore, compounds 2, 4, and 6 reduced LPS-induced inducible nitric oxide synthase (iNOS) expression in a dose-dependent manner. Pre-incubation of cells with these compounds also significantly suppressed LPS-induced COX-2 protein expression. Compounds 2, 4, and 6 also showed cytotoxic activity against HL-60 cells with IC50 values ranging between 46.43 and 94.06 μM.
