Fraction C-3b (700 mg) was divided into three portions (C-3b-1-C-3b-3), of which fraction C-3b-2 (20 mg) was purified by semi-preparative HPLC eluting with 60% aqueous MeOH to produce 7 (8 mg). Fraction C-3c (350 mg) was purified by RP-18 column eluting with gradient aqueous MeOH (50-100%) to yield a nearly pure fraction, which was recrystallized in MeOH to afford 3 (78 mg).

    • 2 at 37 °C. After 24 h pre-incubation, cells were treated with serial dilutions of the compounds 1-7 with the maximum concentration of 25 μM in the presence of 1 μg/mL LPS for 18 h. Each compound was dissolved in DMSO and further diluted in medium to produce different concentrations. NO production in each well was assessed by adding 100 μL of Griess reagents A and B to 100 μL of each supernatant from LPS or the compound-treated cells in triplicate. After 5 min incubation, the absorbance was measured at 570 nm with 2104 Envision Multilabel Plate Reader (Perkin-Elmer Life Sciences, Inc., Boston, MA, USA). Cytotoxicity was determined by the MTT assay. MG-132 was used as a positive control.
