In hydrogenchloride; | D. Genistein via Hydrolysis and Crystallization: About 49.0 mg of <strong>[529-59-9]genistin</strong> were refluxed in 15 ml 4N HCl for five hours at 105+-5 C. About 22.9 mg of genistein was obtained with about 75% recovery. About 13 mg genistein from the previous step was extracted twice with 50 ml diethyl ether. The extracts were combined, and evaporated to dryness. The solids obtained were crystallized from 2 ml of a solution made from 3 parts ethanol and 2 parts water. About 8.2 mg of the genistein crystal was obtained with 63% recovery and about 99% purity. |

12.5% | In dimethyl sulfoxide; for 240h;Large scale; Enzymatic reaction; | General procedure: Portions of 1.5 mL of the 3-day inoculation culture were transferred to 300 mL Erlenmeyer flasks,each containing 100 mL of the medium. In the preparative (large scale) biotransformation, a total of60 mg of each substrate dissolved in 6 mL of DMSO and was equally distributed among four flasks with4-day fungal cultures to give a final concentration of 150 mg/L. After 10 days of incubation, the cultureswere acidified with 1 M HCl to pH around 5 and three time extracted with the same volume of ethylacetate. The other procedures and culture conditionswere the same as those of the screening experiments.The collected organic phase was dried over anhydrous MgSO4, the solvent was filtered, evaporatedin a vacuum and analyzed using TLC and HPLC. The biotransformation products were separated bycolumn chromatography on silica gel 60 (230-400 mesh,Merck, Darmstadt, Germany) using chloroform:methanol (3:1 v/v) as eluent. TLC was carried out with Merck silica gel 60, F254 (0.2 mm thick)plates using the same eluents. Products were detected by inspecting plates under UV irradiation.Rf: 0.53 (genistin); 0.64 (sissotrin, isosissotrin); 0.77 (4?-O-methyldaidzin); 0.79 (4?-O-methylgenistin);0.84 (4?-O-methylsissotrin); 0.85 (genistein); 0.87 (daidzein); 0.89 (biochanin A). |

With magnesium(II) chloride hexahydrate; glycosyltransferase from Arabidopsis thaliana; In aq. buffer; at 37.0℃; for 3h;pH 7.5;Enzymatic reaction; | General procedure: After checking the expression of protein, glycosylation reactions were carriedout using crude protein (AtUGT89C1) with genistein and sugars (T/UDP-α-Dglucose,UDP-α-D-galactose, UDP-α-D-glucuronic acid, UDP-α-D-N-acetyl-Dglucosamine,UDP-α-DN-acetylgalactosamine, dTDP-β-L-rhamnose, dTDP-α-2-deoxy-D-glucose, and <strong>[15839-70-0]GDP-β-L-fucose</strong>) as sugar donors. The reaction was carriedout in a total volume of 200 μL containing 100mMTris-HCl (pH 7.5) buffer, 2mMNDP sugar, 2 mM genistein, 10 mM MgCl2. 6H2 O, and 30 μL of crude protein(enzyme concentration was not calculated). The reaction mixtures were incubatedat 37C for 3 h. The reaction mixture lacking enzyme served as the control. Thereactionwas quenched by adding 400 μL chilled methanol and vortexing for severalminutes. Aliquots were centrifuged at 16,000×g to remove denatured proteins, andthe reaction products were monitored by HPLC coupled with a photodiode array(PDA), with 20 μL injected after proper dilution. |

With flavonoid 7-O-glucosyltransferase from Andrographis paniculata; In methanol; at 30℃; for 12h;Enzymatic reaction; | General procedure: All assays and incubations were performed in 100 ll of 50mM Tris-HCl (pH 8.0)containing 8 lg of purified proteins, 200 lM aglycone, and 3200 lM UDP-glucose.The reactions were incubated at 30 C for 12 h and terminated by the addition of200 ll of methanol. The products of the reactions were filtered through a 0.22-lmnylon syringe filter and analyzed using a Waters Acquity UPLC-I-Class system(Waters Corp., Milford, MA) with an Acquity UPLC BEH C18 column (1.7 mm,2.1mm 50 mm). The column temperature was set to 40 C, and the flow rate was400 lL/min. Mobile phase A was a 0.1% formic acid aqueous solution, and mobilephase B was acetonitrile. Gradient programs were used to analyze the reaction mixtures(Table 1). The total conversion rate was calculated to be one percent of the sumof the peak areas of the substrate and product(s). The experiment was performed inthe ESI (-) mode as previously described [17]. |
