A facile transgalactosylation catalyzed by a lipid-coated beta-D-galactosidase in the water-organic two phases

A lipid-coated beta-D-galactosidase could act as an efficient catalyst for transgalactosylation in the water-organic two phases: both the hydrophobic lipid-coated enzyme and alcohols were solubilized in isopropyl ether and mixed with an aqueous solution of lactose (a galactosyl donor). When a native beta-D-galactosidase was employed for the same reaction, neither the transgalactosylation nor the hydrolysis reaction proceeded due to the deactivation of the enzyme at the interface.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10343-06-3 is helpful to your research., Synthetic Route of 10343-06-3

Chitosan as an adhesive

Chitosan is a well-known polysaccharide abundantly published during the last decades. This heteropolymer, composed of 2-acetamido-2-deoxy-d-glucopyranose and 2-amino-2-deoxy-d-glucopyranose, is obtained after alkaline deacetylation of chitin from crustaceans, fungi and other non-vegetable organisms. Soluble only at acidic pH, it is the unique polycationic polysaccharide extracted from bioresources. This characteristic gives to it original and specific properties finding some applications in several industrial fields but especially in the biomedical one because of its biocompatibility and its non-toxicity. Besides these traditional applications other ones begin actually to appear in the literature. They focus on the development of chitosan-based adhesives, binders or films. This review synthetizes the state of the art on this domain, but also deals with the assessment of chitosan environmental impact.

N-methyl-N-phenyl-5-oxa-1-azaspiro[2.5]oct-1-en-2-amine – Synthesis and reactions of a synthon for AN UNKNOWN alpha-AMINO ACID

The synthesis of the heterospirocyclic amino azirine N-methyl-N-phenyl-5- oxa-1-azaspiro[2.5]oct-1-en-2-amine (6a) was achieved from 3,4-dihydro-2H-pyrane (7) via N-methyl-N-phenyltetrahydropyran-3-thiocarboxamide (11). The reactions of 6a with thiobenzoic acid and Z-Phe-OH, respectively, leading to the corresponding 3-benzoylaminotetrahydropyran-3-thiocarboxamide (13) and the diastereoisomeric dipeptide amides (14), respectively, demonstrate that 6a is a valuable synthon for the hitherto unknown 3-aminotetrahydropyrane-3-carboxylic acid.

Photoinduced, Copper-Catalyzed Decarboxylative C-N Coupling to Generate Protected Amines: An Alternative to the Curtius Rearrangement

The Curtius rearrangement is a classic, powerful method for converting carboxylic acids into protected amines, but its widespread use is impeded by safety issues (the need to handle azides). We have developed an alternative to the Curtius rearrangement that employs a copper catalyst in combination with blue-LED irradiation to achieve the decarboxylative coupling of aliphatic carboxylic acid derivatives (specifically, readily available N-hydroxyphthalimide esters) to afford protected amines under mild conditions. This C-N bond-forming process is compatible with a wide array of functional groups, including an alcohol, aldehyde, epoxide, indole, nitroalkane, and sulfide. Control reactions and mechanistic studies are consistent with the hypothesis that copper species are engaged in both the photochemistry and the key bond-forming step, which occurs through out-of-cage coupling of an alkyl radical.

The formation of 3,6-di-O-acetyl-1,2,4-O-orthoacetyl-alpha-d- glucopyranose was observed in the gold(i)-catalyzed glycosidation of peracetyl glucopyranosyl ortho-hexynylbenzoate; experiments with substrates bearing deuterium labeled 2-O-acetyl or 4-O-acetyl groups indicated that the orthoacetate was derived from the 4-O-acetyl group, which provided a direct evidence for the remote participation of the 4-O-acyl group in glycosylation.

Discovery of (3 S,3a R)-2-(3-chloro-4-cyanophenyl)-3-cyclopentyl-3,3a,4,5- tetrahydro-2 H -benzo[ g ]indazole-7-carboxylic acid (PF-3882845), an orally efficacious mineralocorticoid receptor (MR) antagonist for hypertension and nephropathy

We have discovered a novel class of nonsteroidal pyrazoline antagonists of the mineralocorticoid receptor (MR) that show excellent potency and selectivity against other nuclear receptors. Early analogues were poorly soluble and had a propensity to inhibit the hERG channel. Remarkably, both of these challenges were overcome by incorporation of a single carboxylate moiety. Structural modification of carboxylate-containing lead R-4g with a wide range of substituents at each position of the pyrazoline ring resulted in R-12o, which shows excellent activity against MR and reasonable pharmacokinetic profile. Introduction of conformational restriction led to a novel series characterized by exquisite potency and favorable steroid receptor selectivity and pharmacokinetic profile. Oral dosing of 3S,3aR-27d (PF-3882845) in the Dahl salt sensitive preclinical model of salt-induced hypertension and nephropathy showed blood pressure attenuation significantly greater than that with eplerenone, reduction in urinary albumin, and renal protection. As a result of these findings, 3S,3aR-27d was advanced to clinical studies.

Glycosylidene Carbenes Part 5 Synthesis of Glycono-1,5-lactone Tosylhydrazones as Precursors of Glycosylidene Carbenes

The benzyl- and the acyl-protected glyconolactone tosylhydrazones 6, 9, 12, 16, and 19 (Scheme 1) were prepared in good yields by treating the hemiacetals 4, 7, 10, 14, and 17 with N-tosylhydrazine, to give the N-glycosylhydrazines 5, 8, 11, 15, and 18, and by oxidizing these hydrazines with N-bromosuccinimide (NBS) in the presence of 1,8-diazabicyclo<5.4.0>undec-7-ene (DBU), with CrO3-dipyridine complex or with pyridinium dichromate.Photolysis of the sodium salt 20 of 6 (Scheme 2) in the presence of N-phenylmaleimide, dimethyl fumarate, or acrylonitrile gave the corresponding cyclopropanes 21-28 in satisfactory yields.Photolytic or thermolytic glycosidation of phenol and 4-methoxyphenol by 20 yielded the anomeric glycosides 29/30 and 31/32, yields being marginally higher for the thermolytic process.Photolytic glycosidation of propan-2-ol gave the glycosides 33 and 34 in low yields only.Yields and ratios of products were compared to those obtained with the diazirine 1 as a source of glycosylidene carbenes.While the yields from 20 are lower, the ratios of products obtained in the photolytic reactions are in agreement with the formation of a common intermediate from both carbene precursors.

Stereocontrolled 1,3-phosphatyloxy and 1,3-halogen migration relay toward highly functionalized 1,3-dienes

A double migratory cascade reaction of alpha-halogen-substituted propargylic phosphates to produce highly functionalized 1,3-dienes has been developed. This transformation features 1,3-phosphatyloxy group migration followed by 1,3-shifts of bromine and chlorine as well as the unprecedented 1,3-migration of iodine. The reaction is stereodivergent: (Z)-1,3-dienes are formed in the presence of a copper catalyst, whereas gold-catalyzed reactions exhibit inverted stereoselectivity, producing the corresponding E products.
