Three new compounds, (3S)-dihydrobonducellin 8-O-β-D-glucopyranoside (1), 3',5'-dimethoxy-jezonolid (2), and latisilinoid (3), along with 16 known compounds, were isolated from the twigs of Caesalpinia latisiliqua (Leguminosae). The known compounds were identified as flavonoids, stilbenes, and phenolics as determined by extensive spectroscopic methods, including 1D and 2D NMR. All the isolated compounds were evaluated for their antiviral activity in HRV1B-, CVB3-, and EV71-infected cells. Among the tested compounds, three flavonoids (4-6) and two stilbenes (12 and 14) exhibited significant antiviral activity. This is the first phytochemical investigation of C. latisiliqua twigs.[1]

Antiviral assay[1]
Antiviral activity was assayed by employing the SRB method using CPE reduction, as recently reported. To evaluate the activity, 3 × 104 cells per well of HeLa or Vero cells were seeded using MEM supplemented with 10% FBS and 0.01% antibiotic–antimycotic solution onto a 96-well culture plate and incubated for 24 h. After the medium was removed and cells were washed with 100 μL of phosphate buffered saline, the diluted virus suspension (0.09 ml), containing a 50% cell culture infective dose (CCID50) of the virus, was added to HeLa or Vero cells to produce the 50% CPE within 48 h after infection. Next, MEM containing 10 μM of the compounds (0.01 ml) was added and the culture plates were incubated at 37 °C in 5% CO2 for 2 days until 50% CPE was achieved. The 96-well plates were washed once with 200 μL of PBS. Ice-cold 70% acetone in water (100 μL) was added to each well and incubated for 30 min at −20 °C. After removing the 70% acetone, plates were dried in a drying oven at 55 °C for 30 min. Next, 0.4% (w/v) SRB in 1% acetic acid solution (100 μL) was added to each well and left for 30 min at room temperature. The SRB solution was then removed and the plates were washed five times with 1% acetic acid in water before oven-drying at 55 °C. Bound SRB was then solubilised with 10 mM unbuffered Tris-base solution (100 μL). After 30 min, the absorbance was read at 540 nm using a VersaMax microplate reader with a reference absorbance at 620 nm. The antiviral activity of each test compounds in HRV1B-, CVB3-, and EV71-infected cells was calculated as a percentage of the corresponding untreated control. |

Cell culture[1]
The HRV1B, CVB3, and EV71 were obtained from the Division of Vaccine Research of the Korea Centers for Disease Control and Prevention and were propagated at 37 °C in Vero and 32 °C in HeLa cells. HRV1B was expanded in HeLa cells, while CVB3 and EV71 were expanded in Vero cells. These cells were maintained in minimum essential medium (MEM) supplemented with 10% fetal bovine serum (FBS) and 0.01% antibiotic–antimycotic solution. The cells were incubated in MEM supplemented with 10% FBS and 0.01% antibiotic–antimycotic solution in a humidified atmosphere of 5% CO2 at 37 °C. Cells were detached using trypsin-EDTA. Five subsequent cycles of subculturing were performed before the cells were incubated with isolated compounds. |

| Additional Infomation |
Cis-resveratrol is the cis-stereoisomer of resveratrol.
(Z)-resveratrol has been reported in Malus, Botrytis cinerea, and other organisms with data available. A stilbene and non-flavonoid polyphenol produced by various plants including grapes and blueberries. It has anti-oxidant, anti-inflammatory, cardioprotective, anti-mutagenic, and anti-carcinogenic properties. It also inhibits platelet aggregation and the activity of several DNA HELICASES in vitro. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
