Quantification of Glucosinolates by HPLC
Cited 8 times
A C18 column (Phenomonex, SphereClone 5μ ODS(2)) was equilibrated for 3 h with a mobile phase which consisted of 80 mL (0.02 M) TBA (tetrabutylammonium bromide) and 20 mL ACN (acetonitrile) with detection at 229 nm. The flow rate was set at 1.0 ml/min and separated according to programme for desulfoglucosinolates detailed in Table 3.

Solution A: 100% TBA (0.02 M)

Solution B: 70:30, TBA (0.02 M):acetonitrile

Glucosinolates were quantified using the chromatogram from 229 nm and standard curves were constructed using pure sinigrin (sigma aldrich), glucotropaeolin, glucoraphenin, glucoraphanin, glucerucin, glucobrassicin, gluconasturtiin, sinalbin, progoitrin and glucoiberin (phytoplan).
In the case of glucoraphasatin in R. sativus leaves and glucotropaeolin in B. juncea minor alterations were made to avoid peaks co-eluting. The mobile phase programme for R. sativus leaves was 100% A for 5 min, followed by a 35 min linear gradient to 66% B followed by a 5 min linear gradient to 100% B followed by a 5 min linear gradient to 100% A. For B. juncea leaves, an isocratic 85:15, TBA (0.02 M):acetonitrile mobile phase for 70 min was used.

Electrochemical Superoxide Scavenging Assay
Cited 5 times
Stock solutions of quercetin and chrysin were made to approximately 7.9 × 10−4 M in anhydrous DMSO and used in trials. For the experiment, a solution of tetrabutylammonium bromide in anhydrous DMSO is bubbled for 10 min with a dry O2/N2 gas mixture to establish the dissolved oxygen level in the electrochemical cell. An initial blank is run on this solution by cycling the cell from a potential of +0.10 volts relative to the reference electrode, moving initially in the negative direction to a potential of −1.5 volts. The reduction peak was observed at −0.6 volts due to the reduction of molecular oxygen (O2) to the superoxide ion, O2−•, on reversal of the sweep, an oxidation peak is observed at −0.3 volts. The height of the oxidation peak is measured and together with the previous calibration gives the concentration of superoxide ion in the vicinity of the electrode surface. Next, an aliquot of one of the antioxidants was added, the solution bubbled with the gas mixture for 2 min and the CV rerecorded. Again the oxidation peak is measured and the change in magnitude from the “blank” is taken as the amount of superoxide removed by the scavenger. From the known addition of flavonoid and the amount of superoxide ion removed, the ratio of moles of superoxide scavenged to moles of flavonoid added may be calculated. Additional aliquots of each flavonoid are added to generate a reaction curve for each flavonoid.

Enzymatic Assay for dNTPase Activity

dNTPase assays were carried out in a reaction buffer containing 10 mm Tris-HCl, pH 7.5, 50 mm NaCl, 5 mm MgCl2, appropriate dNTPs each at 100 μm, and 56 nm (28 pmol) recombinant SAMHD1 at 25 °C. Aliquots collected at various time points were diluted into 9 volumes of ice-cold PBS to stop the reaction and spun through an Amicon Ultra 0.5-ml 10 kDa filter (Millipore) at 14,000 × g for 20 min. Deproteinized samples were analyzed by HPLC using an Eclipse XDB-C18 4.6- × 150-mm column (Agilent). The column was equilibrated in 0.1 m KH2PO4, 10 mm tetrabutylammonium bromide, pH 6.5 (Solvent A). Injected samples were eluted with a linear gradient of 0–7.5% acetonitrile in solvent A, over 30 min followed by 7.5% acetonitrile in solvent A for 20 min at flow rate of 1 ml/min. Alternatively, deoxyribonucleosides and dNTPs were separated over a CapCell Pak C18 4.6- × 250-mm column (Phenomenex) pre-equilibrated with 10 mm ammonium phosphate, pH 7.8, and 4.8% methanol. Then they were eluted with a linear gradient of 4.8–19.2% methanol over 22.5 min at a flow rate of 1.5 ml/min. The amounts of substrates and products were quantified by peak integration of the absorbance data recorded at 260 nm. For chemical cross-linking experiments, the reactions were assembled in the absence or presence of the indicated dGTP concentrations and preincubated on ice for 30 min, diluted with equal volume of 2% formaldehyde solution in PBS to a final concentration of 1%, followed by incubation for 15 min at room temperature. The cross-linking reactions were quenched with 0.25 m glycine for 15 min at room temperature, resolved by SDS-PAGE, and SAMHD1 was revealed by silver staining.

Hydrophobicity Modification of Humic Materials
Details on the derivatization reaction to modify the hydrophobicity of humic materials were previously reported (Piccolo et al. 2023 (link)). Briefly, HA were dissolved in deionized water, the pH was adjusted to 9.0 with a 1.5 M NaOH solution, and the phase-transfer catalyst TBAH (tetrabutylammonium hydroxide) (Bu4N+OH−) was added to the solution. After 2 h stirring at room temperature, specific volumes of each alkyl halide (methyl iodide; pentyl bromide; benzyl bromide) were added to the humic solution in amounts corresponding to 40, 60, and 80% of HA total acidity, in order to partially and progressively saturate the nucleophilic humic sites, and concomitantly maintain the aqueous solubility of the modified humic matter. The reaction mixture was stirred for 2 h at room temperature. Then, the pH was adjusted to 1.0 with a 10% HCl solution to precipitate the reaction products. The excessive alkylating agent was removed under reduced pressure at 50–70 °C, while the residual tetrabutylammonium salts were removed from the reaction products by washing the residue with hot (45 °C) deionized water. Finally, the residue was dialyzed against deionized water and freeze dried. All reagents 98–99% pure were purchased from Aldrich (Milano, Italy) and used without further purification.
