Biocatalytic degradation technology has received a great deal of attention in water treatment because of its advantages of high efficiency, environmental friendliness, and no secondary pollution. Herein, for the first time, horseradish peroxidase and mediator syringaldehyde were co-immobilized into functionalized calcium alginate composite beads grafted with glycidyl methacrylate and dopamine. The resultant biocatalyst of the co-immobilized horseradish peroxidase-syringaldehyde system has displayed excellent catalytic performance to degrade indole in water. The degradation rate of 100% was achieved in the presence of hydrogen peroxide even if the indole concentration was changing from 25 mg/L to 500 mg/L. If only the free enzyme was used under the identical water treatment conditions, the degradation of indole could hardly be observed even when the concentration of indole is low at 25 mg/L. This was attributed to the effective co-immobilization of the enzyme and the mediator so that the catalytic activity of horseradish peroxidase and the synergistic catalytic action of syringaldehyde could be fully developed. Furthermore, while the spherical catalyst was operated in succession and reused for four cycles in 50 mg/L indole solution, the degradation rate remained 91.8% due to its considerable reusability. This research demonstrated and provided a novel biocatalytic approach to degrade indole in water by the co-immobilized horseradish peroxidase-syringaldehyde system as biocatalyst.

Determination of indoles in plasma of polycystic ovarian syndrome patients by high performance liquid chromatography-fluorescence detection

A new method was established for the determination of indoles (indole (IND), 3methylindole (3 -MI), indolyl-3-acetic acid (IAA) and indolyl-3-propionic acid (IPA)) in plasma by high performance liquid chromatography-fluorescence detection (HPLC-FLD). The analytes were separated simultaneously on a Shim -pack VP-ODS column (150 mmx4. 6 mm, 4. 6 tim) using 15 mmol/L sodium dihydrogen phosphate solution and methanol (48 :52, v/v) as the mobile phases. The column temperature was 30 C, and the flow rate was 0. 8 mL/min. The calibration curves of IND, 3 -MI, IPA and IAA showed good linear relationships. The intra-day and inter-day relative standard deviations (RSDs) for the analytes were both less than 6. 31%. The average recoveries of the analytes in plasma were 97. 5% 107. 0%. The method was successfully applied to the analysis of indoles in the plasma of healthy women of reproductive age (n = 25) as controls and patients with polycystic ovarian syndrome (n = 61). The results showed that the concentrations of indoles in the plasma were significantly different between the two groups, and IND was found to be a risk factor and a potential diagnostic biomarker for polycystic ovarian syndrome (PCOS). The method is simple, sensitive and suitable for use in clinical testing and laboratory research.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 481-72-1, in my other articles.

Accumulation of volatile constituents in agar and bioreactor shoot cultures of Verbena officinalis L.

Key message Microshoot cultures of Verbena officinalis, grown in temporary immersion bioreactors, were investigated in terms of essential oil content and composition of volatile fraction In vitro shoot cultures of common vervain (Verbena officinalis L., Verbenaceae) were established and evaluated for essential oil content. The shoots were maintained as stationary microshoot culture, grown on Schenk-Hildebrandt medium supplemented with 9.84 mu M of 2-isopentenyladenine and 1.0 mu M of thidiazuron. The shoots were further adapted to grow in two temporary immersion bioreactors (RITA and Plantform), using Schenk-Hildebrandt medium supplemented with 4.92 mu M indole-3-butyric acid. The best growth, in terms of dry weight production, was recorded for agar culture (0.73 g l(-1) day(-1)), followed by 35 days (day) Plantform (0.53 g l(-1) day(-1)), 35 days RITA (0.42 g l(-1) day(-1)) and 56 days Plantform culture (0.29 g l(-1) day(-1)). The volatile fractions were obtained by simultaneous hydrodistillation-extraction of the plant materials using Likens-Nickerson apparatus. Aerial parts of V. officinalis intact plant and 56 d Plantform culture had the highest essential oil content (8.1 g kg(-1)) whereas the stationary agar culture excelled in essential oil productivity (5.0 mg l(-1) day(-1)). The volatile oils isolated from in vitro shoots contained 1-octen-3-ol, benzyl alcohol, phenethyl alcohol, coumaran and hexadecenoic acid as major constituents. 1-Octen-3-ol was the predominant (> 50%) constituent of 35 day shoot cultures maintained in temporary immersion bioreactors whereas coumaran (19%) and hexadecanoid acid (21%) prevailed in stationary microshoot culture. The volatile fraction obtained from aerial parts of V. officinalis intact plant was composed mainly of hexadecanoic acid (> 20%), linalool (> 8%), anethole (> 5%) and carvone (> 3%).

Lewis Acid-Controlled Regioselective Phosphorylation of 2-Indolylmethanols with Diarylphosphine Oxides: Synthesis of Highly Substituted Indoles

The Lewis acid-promoted phosphorylation of 2-indolylmethanols with diarylphosphine oxides is described. The regioselectivity of the reaction can be modulated by the choice of rare earth metal Lewis acid, offering a highly selective approach to structurally diverse indole derivatives in up to 97% yield for over 50 examples. This strategy features high selectivity, good functional group tolerance, and easy scalability. The utility of this method is further highlighted by facile modification of the products to access novel indole-based phosphine ligand.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 481-72-1, you can contact me at any time and look forward to more communication. Formula: C15H10O5.
