Cited 21 times
Protein concentration was determined using a BCA assay (Pierce). The indicated amounts of antibodies and lysates were incubated for 1 h, after that 10 to 25 μl protein G agarose beads (Immobilized Protein G, Pierce) were added and immunoprecipitation was performed overnight. All steps were performed with mild agitation at 4°C. For mass spectrometric analysis, lysates were precleared by incubation with the same amount of beads for 2 h before the antibody was added. The supernatants of the immunoprecipitations were kept for analysis and the beads were washed either twice with PBS for western blot analysis or three times with RIPA buffer for mass spectrometric analysis. 4x reducing SDS Loading Dye (500 mM Tris HCl, pH 6.8, 8% SDS, 40% glycerine, 20% β-mercaptoethanol, 5 mg/ml bromophenol blue) was added to the beads as well as to the lysates and the supernatants and samples were incubated at either 65°C or 99°C for 5 min or 10–20 min, respectively, before they were separated by SDS PAGE using a 8% Laemmli gel [19 (link)]. For western blot analysis, proteins were transferred via a semi-dry procedure on polyvinylidene difluoride membranes (Pall Corporation), blocked for 1 h at RT with 5% milk powder in PBST (PBS, 0.1% Tween 20) and incubated with JB1A (0.1 μg/ml) overnight at 4°C. Membranes were either incubated with anti-mouse HRP or anti-mouse Alexa Fluor 680 (both 1 : 10000) for 1 h at RT. Membranes treated with anti-mouse Alexa Fluor 680 were scanned with a fluorescence scanner (Odyssey, LICOR) using excitation/emission wavelengths of 700 and 800 nm, whereas signals on anti-mouse HRP incubated membranes were detected with chemiluminescence solution (ECL, GE Healthcare). Quantitation of immunoblot analysis was performed using the software ImageJ [20 ]. Silver staining was performed using a modified protocol of Gharahdaghi et al. [21 (link)]. Briefly, gels were fixed with 10% acetic acid/10% methanol, washed with water and sensitized with 1 μg/ml dithiothreitol for 15 min. Gels were incubated in 0.1% (w/v) silver nitrate for 15 min and developed with 0.02% (w/v) paraformaldehyde in 3% (w/v) potassium carbonate until the desired staining had occurred. The reaction was stopped by addition of acetic acid.

Determination of Antioxidant Potential in Plant Extracts
Cited 19 times
Determination of total phenolic content (TPC): Amount of TP were assessed using the Folin-Ciocalteu reagent [25 ]. Briefly, the crude extract (50 mg) was mixed with Folin-Ciocalteu reagent (0.5 mL) and deionized water (7.5 mL). The mixture was kept at room temperature for 10 min, and then 20% sodium carbonate (w/v, 1.5 mL) was added. The mixture was heated in a water bath at 40 oC for 20 min and then cooled in an ice bath; absorbance was read at 755 nm using a spectrophotometer (U-2001, Hitachi Instruments Inc., Tokyo, Japan). Amounts of TP were calculated using gallic acid calibration curve within range of 10-100 mgL-1(R2 = 0.9986). The results were expressed as gallic acid equivalents (GAE) g/100g of dry plant matter. All samples were analyzed thrice and the results averaged. The results are reported on dry weight basis (DW).
Determination of total flavonoid contents (TFC): The TFC were measured following a previously reported spectrophotometric method [26 (link)]. Briefly, extracts of each plant material (1 mL containing 0.1 mg/mL) were diluted with water (4 mL) in a 10 mL volumetric flask. Initially, 5% NaNO2 solution (0.3 mL) was added to each volumetric flask; at 5 min, 10% AlCl3 (0.3 mL) was added; and at 6 min, 1.0 M NaOH (2 mL) was added. Water (2.4 mL) was then added to the reaction flask and mixed well. Absorbance of the reaction mixture was read at 510 nm. TFC were determined as catechin equivalents (g/100g of dry weight). Three readings were taken for each sample and the results averaged.
Determination of reducing power: The reducing power of the extracts was determined according to the procedure described earlier [27 ], with a slight modification. Concentrated extract (2.5-10.0 mg) was mixed with sodium phosphate buffer (5.0 mL, 0.2 M, pH 6.6) and potassium ferricyanide (5.0 mL, 1.0%); the mixture was incubated at 50 oC for 20 min. Then 10% trichloroacetic acid (5 mL) was added and the mixture centrifuged at 980 g for 10 min at 5 °C in a refrigerated centrifuge (CHM-17; Kokusan Denki, Tokyo, Japan). The upper layer of the solution (5.0 mL) was decanted and diluted with 5.0 mL of distilled water and ferric chloride (1.0 mL, 0.1%), and absorbance read at 700 nm using a spectrophotometer (U-2001, Hitachi Instruments Inc., Tokyo, Japan). All samples were analyzed thrice and the results averaged.
DPPH. scavenging assay: 1, 1’–diphenyl–2-picrylhydrazyl (DPPH) free radical scavenging activity of the extracts was assessed using the procedure reported earlier [28 (link)]. Briefly, to extract (1.0 mL) containing 25 μg/mL of dry matter in methanol, freshly prepared solution of DPPH (0.025 g/L, 5.0 mL) was added. Absorbance at 0, 0.5, 1, 2, 5 and 10 min was measured at 515 nm using a spectrophotometer. The scavenging amounts of DPPH radical (DPPH.) was calculated from a calibration curve. Absorbance read at the 5th min was used for comparison of radical scavenging activity of the extracts.
Determination of antioxidant activity in linoleic acid system: The antioxidant activity of the tested plant extracts was also determined by measuring the oxidation of linoleic acid [28 (link)]. Five mg of each plant extract were added separately to a solution of linoleic acid (0.13 mL), 99.8% ethanol (10 mL) and 0.2 M sodium phosphate buffer (pH 7, 10 mL). The mixture was made up to 25 mL with distilled water and incubated at 40 oC up to 360 h. Extent of oxidation was measured by peroxide value applying thiocyanate method as described by Yen et al. [27 ]. Briefly, ethanol (75% v/v, 10 mL ), aqueous solution of ammonium thiocyanate (30% w/v, 0.2 mL), sample solution (0.2 mL) and ferrous chloride (FeCl2) solution (20 mM in 3.5% HCl; v/v, 0.2 mL) were added sequentially. After 3 min of stirring, the absorption was measured at 500 nm using a spectrophotometer (U-2001, Hitachi Instruments Inc., Tokyo, Japan). A control contained all reagents with exception of extracts. Synthetic antioxidants butylated hydroxytoluene (BHT) was used as a positive control. Percent inhibition of linoleic acid oxidation was calculated with the following equation: 100 – [(increase in absorbance of sample at 360 h / increase in absorbance of control at 360 h) × 100], to express antioxidant activity.

Enzyme Kinetic Assay for Cocaine Hydrolysis
Cited 10 times
Initial in vitro screening of the enzyme activity against (−)-cocaine was carried out by using a single concentration (1 mM) of (−)-cocaine, assuming that KM << 1 mM such that the enzyme was always saturated by 1 mM (−)-cocaine and the maximum reaction velocity (Vmax) was reached for a given concentration [E] of the enzyme. Vmax = kcat[E]. The relative concentrations of the enzymes were determined by using an enzyme-linked immunosorbent assay (ELISA)26 (link),52 (link) described below. The ELISA buffers used in the present study are the same as those described in literature.26 (link),52 (link) Specifically, the coating buffer was 0.1 M sodium carbonate/bicarbonate buffer (pH 9.5). The washing buffer (PBS-T) was 0.01 M potassium phosphate monobasic/potassium phosphate monohydrate buffer (pH 7.5) containing 0.05% (vol/vol) Tween 20. The diluent buffer (EIA buffer) was potassium phosphate monobasic/potassium phosphate monohydrate buffer (pH 7.5) containing 0.9% sodium chloride and 0.1% bovine serum albumin (BSA).
To measure (−)-cocaine and benzoic acid, the product of the enzymatic (−)-cocaine hydrolysis, we used sensitive radiometric assays based on toluene extraction of [3H](−)-cocaine labeled on its benzene ring.24 (link) In brief, to initiate the enzymatic reaction, 100 nCi of [3H](−)-cocaine was mixed with 100 µl of enzyme solution. For Michaelis-Menten kinetic analysis, the enzymatic reactions proceeded at 37°C and pH 8 with varying concentrations of (−)-cocaine. The reactions were stopped by adding 200 µl of 0.05 M HCl, which neutralized the liberated benzoic acid while ensuring a positive charge on the residual (−)-cocaine. [3H]benzoic acid was extracted by 1 ml of toluene and measured by scintillation counting. Finally, the measured (−)-cocaine concentration-dependent radiometric data were analyzed in terms of the standard Michaelis-Menten kinetics so that the catalytic parameters were determined. The enzyme activity assays with [3H]ACh were similar to the assays with [3H](−)-cocaine. The primary difference was that the enzymatic reaction was stopped by addition of 200 µl of 0.2 M HCl containing 2 M NaCl and that the product was [3H]acetic acid for the ACh hydrolysis.

Synthesis of Benzothiazole-Propargyl Derivative
Potassium carbonate (250 mg,1.8 mmol) was suspended in acetonitrile, and A2 was added to it. One equivalent of propargyl bromide (1.8 mmol) was added and a catalytic amount of potassium iodide (0.1 equivalents) was added to the reaction mixture. The reaction was refluxed at 90 °C overnight. The reaction was filtered to remove excess potassium carbonate, and acetonitrile was removed under vacuum. Water was added to the mixture, then the product was extracted in dichloromethane twice. The combined organic phases were washed with brine and dried over anhydrous sodium sulfate to yield A3 (85% yield). The alternate route for A3 synthesis was obtained by modifying a literature method [34 (link)]. Commercially available 2-(chloromethyl)-1,3-benzthiazole was reacted with propargyl amine in the presence of a catalytic amount of potassium iodide and 3 equivalents of potassium carbonate in acetonitrile under reflux condition for 12 h. The product intermediate was isolated using solvent extraction to yield A3.
