Chitin is one of the most abundant and cheaply available biopolymers in Nature. Chitin has become a valuable starting material for many biotechnological products through manipulation of its N-acetyl functionality, which can be cleaved under mild conditions using the enzyme family of de-N-acetylases. However, the chemoselective enzymatic re-acylation of glucosamine derivatives, which can introduce new stable functionalities into chitin derivatives, is much less explored. Herein we describe an acylase (CmCDA from Cyclobacterium marinum) that catalyzes the N-acylation of glycosamine with a range of carboxylic acids under physiological reaction conditions. This biocatalyst closes an important gap in allowing the conversion of chitin into complex glycosides, such as C5-modified sialosides, through the use of highly selective enzyme cascades.

Stability constants of the ternary complexes of copper(II) with tertiary diimines as primary ligands and bidentate amides as secondary ligands have been determined by potentiometric titrations at 30 deg C in 50percent (v/v) aqueous dioxane at 0.2 M.The log KMAL values have been determined using the computer programme SCOGS.The complexes have been isolated in solid state and characterized by elemental analyses, conductivity and magnetic measurements and electronic and IR spectral studies.The order of stabilization in the ternary complexes (i.e. Deltalog K = log KMALMA – log K MLM values) has been explained on the basis of the electron repulsion concept.This has also been correlated with the shift in energy of the ligand field transition in the ternary complexes from the average value for the corresponding binary complexes.

There is an urgent need for strategies to combat dengue and other emerging viral infections. We reported that cyclin G-associated kinase (GAK), a cellular regulator of the clathrin-associated host adaptor proteins AP-1 and AP-2, regulates intracellular trafficking of multiple unrelated RNA viruses during early and late stages of the viral lifecycle. We also reported the discovery of potent, selective GAK inhibitors based on an isothiazolo[4,3-b]pyridine scaffold, albeit with moderate antiviral activity. Here, we describe our efforts leading to the discovery of novel isothiazolo[4,3-b]pyridines that maintain high GAK affinity and selectivity. These compounds demonstrate improved in vitro activity against dengue virus, including in human primary dendritic cells, and efficacy against the unrelated Ebola and chikungunya viruses. Moreover, inhibition of GAK activity was validated as an important mechanism of antiviral action of these compounds. These findings demonstrate the potential utility of a GAK-targeted broad-spectrum approach for combating currently untreatable emerging viral infections.

2,2′-Dipyridyltrimethylsilylamine reacts with chloro- and bromomethyl(methyl)chlorosilanes to give Si-functional 1-(2-pyridone-(2′-pyridyl)imine) methylsilanes.Their solid state and solution structures have been determined.Depending on the halogen and the number of halogen atoms neutral pentacoordinate Si-species, RN-2-(C5H4NCH2SiMexCl3-x) (R = 2-C5H4N; x = 1 (2); x = 0 (3)) or ionic tetracoordinate Si-species +Br- (4) are obtained in solution and as solids.The solid compound with x = 2 (1) is also pentacoordinate at Si.In solutionthere is an interesting temperature-dependent equilibrium between the neutral pentacoordinate and the ionic tetracoordinate structure (at lower temperature, NMR) of 1.For the pentacoordinate species dissociation of the coordinative Si-N bond and formation of the neutral tetravalent silanes is suggested at higher temperature in solution.The temperature-dependent equilibrium between the isomers of 1 thus follows reversibly the SN2 pathway of nucleophilic substitution at silicon.The solid state structures of 1 and 3 and of 1-methyl-2-(2′-pyridyl)aminopyridinium chloride (5) are discussed.Structural differences between solid 1 and 3 are interpreted in terms of different stages of the SN2 reaction at silicon.
