Boivin, Patrick published the artcileImmobilization of perfluoroalkylated enzymes in a biologically active state onto Perflex support, Recommanded Product: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, the publication is Biotechnology and Applied Biochemistry (1991), 14(2), 155-69, database is CAplus and MEDLINE.

Perflex was introduced as a new fluorocarbon-based technol. for protein immobilization. Due to the hydrophobic character of the support, however, significant loss of enzymic activity may occur upon immobilization of certain enzymes, which appears to be due to a large conformational change of the protein (inversion). Pretreatment of the Perflex support with a neutral fluorosurfactant lessened the surface hydrophobicity, thus decreasing the hydrophobic interaction between the support and the protein. Modification of enzymes with a high number of fluorocarbon residues, which forms a hydrophobic envelope around the protein, also appeared to prevent enzyme inactivation upon immobilization on Perflex support. Moreover, preactivation of the support with either perfluorooctylpropylisocyanate or reactive poly(fluoroalkyl)sugar reagents greatly improved the enzyme particle activity by increasing the amount of immobilized enzyme. Fluorosurfactant treatment of the support activated with perfluorooctylpropylisocyanate improved the retention of activity for sensitive enzymes such as chymotrypsin and increased the wet ability and ease of handling of the Perflex particles.

Borkowski, Olivier published the artcileLarge scale active-learning-guided exploration for in vitro protein production optimization, Computed Properties of 122-20-3, the publication is Nature Communications (2020), 11(1), 1872, database is CAplus and MEDLINE.

Abstract: Lysate-based cell-free systems have become a major platform to study gene expression but batch-to-batch variation makes protein production difficult to predict. Here we describe an active learning approach to explore a combinatorial space of ~4,000,000 cell-free buffer compositions, maximizing protein production and identifying critical parameters involved in cell-free productivity. We also provide a one-step-method to achieve high quality predictions for protein production using minimal exptl. effort regardless of the lysate quality.

Zyakun, A. M. published the artcileApplication of High-Performance Liquid Chromatography/High Resolution Mass Spectrometry to the Investigation of the Biodegradation and Transformation of Phenanthrene by a Plasmid Bearing Rhizosphere Bacteria Pseudomonas aureofaciens, SDS of cas: 86-48-6, the publication is Journal of Analytical Chemistry (2019), 74(13), 1355-1361, database is CAplus.

Mass spectrometry identified metabolites and estimated the efficiency of phenanthrene biodegradation and transformation by the rhizospheric bacteria, Pseudomonas aureofaciens BS1393. P. aureofaciens strains BS1393(pOV17) and BS1393(NPL-41) with various naphthalene biodegradation plasmids were used. Strain BS1393(pOV17) contained the pOV17 wild-type naphthalene biodegradation plasmid which determined naphthalene oxidation Krebs cycle metabolites. Strain BS1393(NPL-41) contained the mutant plasmid, NPL-41, governing the initial stages of naphthalene oxidation to salicylic acid. Phenanthrene biodegradation limiting stages in bacteria with various plasmids was identified according to intermediates accumulation. When bacteria were grown on phenanthrene, main metabolites were: 2-hydroxy-2H-benzo[h]chromene-2-carboxylic acid/trans-4-(1-hydroxynaph-2-yl)-2-oxobut-3-enoic acid; 1-hydroxy-2-naphthoic acid; and salicylic acid. For strain BS1393(pOV17), 2-hydroxy-2H-benzo[h]chromene-2-carboxylic acid/trans-4-(1-hydroxynaph-2-yl)-2-oxobut-3-enoic acid was observed during 1-14 days of cultivation. For strain BS1393(NPL-41), an insignificant amount of this metabolite was observed after only 14 days. Availability of 1-hydroxy-2-naphthoic acid in the growth of both strains showed the limited rate of its further decarboxylation. Salicylic acid as final biodegradation product was obsd for BS1393(NPL-41) growth. For strain BS1393(pOV17), this metabolite was not observed, indicating phenanthrene complete oxidation

Bacher, Emily P. published the artcileA Phosphine-Mediated Dearomative Skeletal Rearrangement of Dianiline Squaraine Dyes, Synthetic Route of 27292-49-5, the publication is Organic Letters (2021), 23(8), 2853-2857, database is CAplus and MEDLINE.

A phosphorus(III)-mediated dearomatization of ortho-substituted dianiline squaraine dyes results in an unusual skeletal rearrangement to provide exotic, highly conjugated benzofuranone and oxindole scaffolds bearing a C3 side chain comprised of a linear conflagration of an enol, a phosphorus ylide, and 2,4-disubstituted aniline. Employing exptl. and computational anal., a mechanistic evaluation revealed a striking dependence on the acidity of the aniline ortho substituent. Notably, the rearrangement adducts underwent rapid and complete reversion to the parent squaraine in the presence of a Bronsted acid.

A number of allylic alcs. bearing a CF₃ group at the α- or γ-position, and α-trifluoromethylated γ-enols and -ynols were prepared by the reaction of CF₃CHO with a variety of organometallic compounds Most of the Reformatskii- or Grignard-type reactions required promotion by ultrasound. E.g., Reformatskii-type reaction of CF₃CHO and BrCH₂CO₂Et in the presence of Zn powder and ultrasound gave CF₃CH(OH)CH₂CO₂Et, which was dehydrated, then reduced (LiAlH₄/AlCl₃) to give CF₃CH:CHCH₂OH. Also prepared were RCH:CHCH(OH)CF₃ (R = Bu, Ph), RCMe:CHCH(OH)CF₃ (same R), CF₃CH(OH)CHR¹CH:CH₂ (R¹ = H, Me, Ph), and CF₃CH(OH)CH₂CCH.

Murayama, Eigoro published the artcileMetal-catalyzed organic photoreactions. Evidence for the long-range electron-transfer mechanism in the uranyl- or iron(III)-catalyzed photoreactions of olefins, Safety of 2-Methyl-3-bromo-2-butanol, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1980), 947-9, database is CAplus.

A mechanism for the title reaction was proposed involving interligand electron transfer from the electron-donating ligand (OH^– or Cl^–) to O₂ through the metal ion and olefin mol. This was verified for the UO₂²⁺-catalyzed photochem. formation of bromohydrins from olefins and polyhalogenated compounds by correlation of the reactivities and product ratios with the half-wave reduction potentials of the polyhalogenated compounds

This study demonstrates the screening of a collection of twelve ¹⁹F-tagged metal-binding pharmacophores (MBPs) against the Zn(II)-dependent metalloenzyme human carbonic anhydrase II (hCAII) by ¹⁹F NMR. The isomorphous replacement of Zn(II) by Co(II) in hCAII produces enhanced sensitivity and reveals the potential of ¹⁹F NMR-based techniques for metalloenzyme ligand discovery.

Peroxodicarbonates are of substantial interest as potentially powerful and sustainable oxidizers but have so far been accessible only in low concentrations with unsatisfactory energy efficiency. Concentrated (> 0.9 mol L^-1) peroxodicarbonate solutions have now been made accessible by the electrolysis of aqueous K₂CO₃/Na₂CO₃/KHCO₃ solutions at high c.d. of 3.33 A cm^-2 in an efficiently cooled circular flow reactor equipped with a boron-doped diamond anode and a stainless-steel cathode. Their synthetic potential as platform oxidizers was clearly demonstrated in transformations including sulfoxidation, N-oxidation, and epoxidation
