Synthesis of N4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-asparagine analogues. L-2-chloro-, L-2-bromo-, and D,L-2-methylsuccinamic acid analogues

L-Chlorosuccinic anhydride, L-bromosuccinic anhydride, and D,L-methylsuccinic anhydride react with 2-acetamido-2-deoxy-beta-D-glucopyranosylamine to give varying mixtures of N4-(beta-GlcNAc)-2-substituted- and N4-(beta-GlcNAc)-3-substituted-succinamic acid isomers. The two regioisomers are separated by anion exchange chromatography. The N4-(beta-GlcNAc)-2-substituted-succinamic acid isomers are characterized as analogues of N4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-asparagine.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 14215-68-0, you can also check out more blogs about14215-68-0

Kinetic Control of Regioselectivity in Glycosidase-catalysed Disaccharide Synthesis: Preparation of 2-Acetamido-4-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-D-glucopyranose (N,N’-diacetylchitobiose) and 2-Acetamido-6-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-D-gluco…

During transfer of the N-acetyl-beta-D-glucosaminyl (2-acetamido-2-deoxy-beta-D-glucopyranosyl)residue from p-nitrophenyl N-acetyl-beta-D-glucosaminide (p-nitrophenyl N-2-acetamido-2-deoxy-beta-D-glucopyranoside) on to N-acetyl-D-glucosamine (2-acetamido-2-deoxy-D-glucopyranose) catalysed by the N-acetylhexosaminidase from Aspergillus oryzae, the major isomer formed was found to depend on the time course of the reaction, 1 -> 4 transfer predominating while the p-nitrophenyl glycoside was available as donor, but 1 -> 6 transfer when the initially-formed 1 -> 4 product took over as donor, results that could be interpreted in terms of a constant regioselectivity modulated by selective hydrolysis of the products.

Enzymatic syntheses and selective hydrolysis of O-beta-d- galactopyranosides using a marine mollusc beta-galactosidase

The use of crude extract of the hepatopancreas of Aplysia fasciata, a large mollusc belonging to the order Anaspidea containing a beta-galactosidase activity, was reported for the synthesis of different galactosides. Good yields with polar acceptors and the uncommon beta-1-3 selectivity in the transgalactosylation reactions with most of the acceptors were observed. A beta-1-2 selectivity in the hydrolytic conditions was also observed and discussed.

Synthesis, spectroscopic characterization, X-ray crystal structure and magnetic properties of dinuclear copper(II) complex with dual end-to-end and end-on cyanate bridges: [Cu2(mu-NCO-N,N?)2(NCO-N) 2(dpyam)2]

A new dinuclear copper(II) complex [Cu2(mu1,1-NCO) 2(NCO)2(dpyam)2] (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction. Two N-bonded cyanato ligands bridge two copper ions in an end-on fashion and two others act as the N-bonded terminal ligands. The copper ion has a distorted square-pyramidal environment. The magnetic susceptibility, measured from 5 to 300 K, has revealed a weak ferromagnetic interaction between the Cu(II) atoms with a singlet-triplet energy gap (J) of 6.03 cm-1. The EPR spectrum, measured as a powdered solid at RT and 77 K, shows an S = 1/2 signal with g? = 2.08 and an unresolved g? of 2.29.

The Identification of Potent, Selective, and Orally Available Inhibitors of Ataxia Telangiectasia Mutated (ATM) Kinase: The Discovery of AZD0156 (8-{6-[3-(Dimethylamino)propoxy]pyridin-3-yl}-3-methyl-1-(tetrahydro-2 H-pyran-4-yl)-1,3-dihydro-2 H-imidazo[4,5- c]quinolin-2-one)

ATM inhibitors, such as 7, have demonstrated the antitumor potential of ATM inhibition when combined with DNA double-strand break-inducing agents in mouse xenograft models. However, the properties of 7 result in a relatively high predicted clinically efficacious dose. In an attempt to minimize attrition during clinical development, we sought to identify ATM inhibitors with a low predicted clinical dose (<50 mg) and focused on strategies to increase both ATM potency and predicted human pharmacokinetic half-life (predominantly through the increase of volume of distribution). These efforts resulted in the discovery of 64 (AZD0156), an exceptionally potent and selective inhibitor of ATM based on an imidazo[4,5-c]quinolin-2-one core. 64 has good preclinical phamacokinetics, a low predicted clinical dose, and a high maximum absorbable dose. 64 has been shown to potentiate the efficacy of the approved drugs irinotecan and olaparib in disease relevant mouse models and is currently undergoing clinical evaluation with these agents.
