Synthesis of hydroxytyrosol, 2-Hydroxyphenylacetic acid, and 3-hydroxyphenylacetic acid by differential conversion of tyrosol isomers using Serratia marcescens strain
J Agric Food Chem 2005 Aug 10;53(16):6525-30.PMID:16076144DOI:10.1021/jf050972w.
We investigated to develop an effective procedure to produce the potentially high-added-value phenolic compounds through bioconversion of tyrosol isomers. A soil bacterium, designated Serratia marcescens strain, was isolated on the basis of its ability to grow on p-tyrosol (4-hydroxyphenylethanol) as a sole source of carbon and energy. During growth on p-tyrosol, Ser. marcescens strain was capable of promoting the formation of hydroxytyrosol. To achieve maximal hydroxytyrosol yield, the growth state of the culture utilized for p-tyrosol conversion as well as the amount of p-tyrosol that was treated were optimized. The optimal yield of hydroxytyrosol (80%) was obtained by Ser. marcescens growing cells after a 7-h incubation using 2 g/L of p-tyrosol added at the end of the exponential phase to a culture pregrown on 1 g/L of p-tyrosol. Furthermore, the substrate specificity of the developed biosynthesis was investigated using m-tyrosol (3-hydroxyphenylethanol) and o-tyrosol (2-hydroxyphenylethanol) as substrates. Ser. marcescens strain transformed completely m-tyrosol and o-tyrosol into 3-hydroxyphenylacetic acid and 2-Hydroxyphenylacetic acid, respectively, via the oxidation of the side chain carbon of the treated substrates. This proposed procedure is an alternative approach to obtain hydroxytyrosol, 2-Hydroxyphenylacetic acid, and 3-hydroxyphenylacetic acid in an environmentally friendly way which could encourage their use as alternatives in the search for replacement of synthetic food additives.
Biotransformation of phenylacetonitrile to 2-Hydroxyphenylacetic acid by marine fungi
Mar Biotechnol (NY) 2013 Feb;15(1):97-103.PMID:22790719DOI:10.1007/s10126-012-9464-1.
Marine fungi belonging to the genera Aspergillus, Penicillium, Cladosporium, and Bionectria catalyzed the biotransformation of phenylacetonitrile to 2-Hydroxyphenylacetic acid. Eight marine fungi, selected and cultured with phenylacetonitrile in liquid mineral medium, catalyzed it quantitative biotransformation to 2-Hydroxyphenylacetic acid. In this study, the nitrile group was firstly hydrolysed, and then, the aromatic ring was hydroxylated, producing 2-Hydroxyphenylacetic acid with 51 % yield isolated. In addition, the 4-fluorophenylacetonitrile was exclusively biotransformed to 4-fluorophenylacetic acid by Aspergillus sydowii Ce19 (yield = 51 %). The enzymatic biotransformation of nitriles is not trivial, and here, we describe an efficient method for production of phenylacetic acids in mild conditions.
Identification of a self-sufficient cytochrome P450 monooxygenase from Cupriavidus pinatubonensis JMP134 involved in 2-Hydroxyphenylacetic acid catabolism, via homogentisate pathway
Microb Biotechnol 2021 Sep;14(5):1944-1960.PMID:34156761DOI:10.1111/1751-7915.13865.
The self-sufficient cytochrome P450 RhF and its homologues belonging to the CYP116B subfamily have attracted considerable attention due to the potential for biotechnological applications based in their ability to catalyse an array of challenging oxidative reactions without requiring additional protein partners. In this work, we showed for the first time that a CYP116B self-sufficient cytochrome P450 encoded by the ohpA gene harboured by Cupriavidus pinatubonensis JMP134, a β-proteobacterium model for biodegradative pathways, catalyses the conversion of 2-Hydroxyphenylacetic acid (2-HPA) into homogentisate. Mutational analysis and HPLC metabolite detection in strain JMP134 showed that 2-HPA is degraded through the well-known homogentisate pathway requiring a 2-HPA 5-hydroxylase activity provided by OhpA, which was additionally supported by heterologous expression and enzyme assays. The ohpA gene belongs to an operon including also ohpT, coding for a substrate-binding subunit of a putative transporter, whose expression is driven by an inducible promoter responsive to 2-HPA in presence of a predicted OhpR transcriptional regulator. OhpA homologues can be found in several genera belonging to Actinobacteria and α-, β- and γ-proteobacteria lineages indicating a widespread distribution of 2-HPA catabolism via homogentisate route. These results provide first time evidence for the natural function of members of the CYP116B self-sufficient oxygenases and represent a significant input to support novel kinetic and structural studies to develop cytochrome P450-based biocatalytic processes.
Determination of 2-Hydroxyphenylacetic acid (2HPAA) in urine after oral and parenteral administration of coumarin by gas-liquid chromatography with flame-ionization detection
J Pharm Biomed Anal 1998 Jul;17(3):487-92.PMID:9656160DOI:10.1016/s0731-7085(97)00224-0.
The urinary excretion of 2-Hydroxyphenylacetic acid (2HPAA) was studied in human volunteers after oral and parenteral doses of coumarin. The presence of 2HPAA in the urine was confirmed by gas chromatography mass spectroscopy (GC MS). Mass spectra of reference material and samples are presented. The determination of 2HPAA was carried out by GC with flame-ionization detection. Prior to analysis samples were extracted into ethyl ether and the analytes were derivatized with trimethlyphenylammonium hydroxide. A calibration range from 0.3 to 150 micrograms ml-1 was established using 3-hydroxyphenyl acetic acid (3HPAA) as an internal standard. On average less than 10% of the coumarin administered were excreted into the urine in the form of 2HPAA.
New furan derivatives from Annulohypoxylon spougei fungus
J Asian Nat Prod Res 2022 Oct;24(10):971-978.PMID:34791983DOI:10.1080/10286020.2021.2004128.
Two new furan derivatives, annulofurans A-B (1-2), together with six known compounds were isolated from Annulohypoxylon spougei fungus. The structures were determined based on NMR and mass spectrometry data. The absolute configurations of annulofurans A-B were determined by Electronic Circular Dichroism (ECD) experiment and comparisons with the experimental ECD spectra of synthesized stereoisomers. The evaluation of the effects on radish and ruzi grass radicle elongation by the isolated compounds showed that annulofuran A affected radicle elongation of ruzi grass. The known 2-Hydroxyphenylacetic acid methyl ester (7) had significant effects against both radish and ruzi grass radicle elongation, which were comparable to the commercial herbicide, glyphosate.
