Materials and Procedures 3.1. Basic Experimental Procedures Optical rotations have been recorded having a 343 Plus polarimeter (Perkin Elmer, Waltham, MA, USA). UV spectra were recorded on a V-530 spectrophotometer (JASCO, Tokyo, Japan). IR spectra had been obtained on a EP Activator Molecular Weight Frontier FT-IR/NIR spectrometer (PerkinElmer, Waltham, MA, USA). CD spectra had been recorded on a JASCO J-815 CD spectrometer (JASCO, Tokyo, Japan). NMR experiments were recorded employing an Avance III 400 spectrometer (Bruker, F landen, Switzerland) and Varian Unity INOVA 500 and 600 spectrometers (Varian, Palo Alto, CA, USA) with TMS because the internal normal. HRESIMS had been determined on Waters Synapt G2 QTOF (Waters, Manchester, UK). TLC was carried out on Merck silica gel F254 precoated glass plates. Chromatography was performed on a Waters 1525 Binary HPLC pump connected to a 996 Photodiode Array (PDA) detector using Isco Allsphere ODS-2 (10 , ten 250 mm) and Zorbax SB-C8 (five , 4.six 150 mm) columns with methanol (solvent A) and water (solvent B). 4 -Dihydroxyacetophenone, two,4-dihydroxybenzaldehyde, 2 ,4 -dihydroxyacetophenone, and 4-hydroxybenzaldehyde had been purchased from Tokyo Chemical Business Co., Ltd. Demethylzeylasteral (DZ) utilized as a reference common within the bioassays was bought from Biopurify Phytochemicals, Ltd. Each of the components for microbial media like Dglucose, peptone, malt extract, yeast extract, and potato dextrose medium have been purchased from Becton, Dickinson and Co. 3.2. Plant Material The roots and rhizomes of licorice (Glycyrrhiza inflata) have been bought from the herbal industry Sehwadang (Gwangju, Korea) in March 2018, which were identified by Dae Hyo Pharmacy Co., Ltd. (Suwon, Korea). three.3. Extraction and Isolation of Substrates 1 and two The dried plant material (two.5 kg) was powdered and extracted with 95 EtOH (7.5 L 3) and was dispersed in water and successively extracted with n-hexane, CH2 Cl2 , EtOAc and n-BuOH. The CH2 Cl2 extract (50 g) was separated by column chromatography eluted with CHCl3 : MeOH to get fractions C1 20. Fraction C11 was additional separated by HPLC to yield compound 1 (30 mg), and fraction C15 was additional separated by HPLC to yield compound two (45 mg). The structures of 1 and two had been confirmed by comparison of their 1 H-NMR data with those previously reported [15,30]. Licoisoflavanone (1): 1 H NMR (CD3 OD, 400 MHz, in ppm, J in Hz) 6.87 (1H, d, J = eight.3, H-6 ), six.66 (1H, d, J = ten.0, H-1″), six.32 (1H, d, J = eight.3, H-5 ), five.89 (1H, d, J = 2.two, H-6), five.88 (1H, d, J = two.two, H-8), five.66 (1H, d, J = ten.0, H-2″), four.58 (1H, t, J = 10.two, H-2a), four.44 (1H, dd, J = 10.2, five.4, H-2b), 4.20 (1H, dd, J = ten.2, five.4, H-3), 1.38 (6H, s, H-4″,5″).Int. J. Mol. Sci. 2021, 22,10 ofGlycyrrhisoflavone (two): 1 H NMR (CD3 OD, 400 MHz, in ppm, J in Hz) 7.96 (1H, s, H-2), six.87 (1H, s, H-6 ), six.71 (1H, s, H-2 ), six.30 (1H, s, H-8), six.19 (1H, s, H-6), five.34 (1H, m, H-2″), 3.35 (2H, d, J = 7.three, H-1″), 1.72 (6H, s, H-4″,5″). 3.4. Synthesis of Substrates 3 and 4 Echinatin (three) and Brd Inhibitor manufacturer isobavachalcone (four) were synthesized for biotransformation because of their low yield from all-natural sources. Briefly, echinatin (three) was synthesized by means of acid-mediated Claisen-Schmidt condensation using 2,4-dihydroxybenzaldehyde with four hydroxyacet
