The hybrid ganglioside X1, which was identified in the bovine brain, was synthesized for the first time. Ganglioside X1 is believed to be involved in the development of amyotrophic lateral sclerosis-like disorders in patients with neurological disorders after treatment with bovine brain gangliosides. A convergent approach using two branched glycan units, the GM2-core trisaccharide and the lacto-ganglio tetrasaccharide, efficiently provided the highly branched heptasaccharide part of ganglioside X1, which was conjugated with the ceramide part to produce the protected ganglioside X1. Global deprotection delivered homogenous ganglioside X1, with which serum from the patient was reacted.

A series of aryl-substituted naphthyridine-based sensors for 9-alkylguanine was analyzed using density functional theory and correlated ab initio methods. First, the 2-acetamido-1,8-naphthyridine backbone of these sensors was examined with rigorous ab initio methods and was shown to exhibit a guanine-binding energy commensurate with that of cytosine. Second, computational analyses of a guanine-specific fluorescent sensor from Fang and co-workers (Org. Lett. 2016, 18, 1724) resulted in a revised binding model and showed that ?-stacking interactions with a pendant pyrenyl group are vital for strong guanine binding. Finally, 24 related guanine sensors with varying aryl groups were studied. Overall, it was found that both the geometry and the point of attachment of the pendant aryl groups significantly impact the guanine-binding affinity. This occurs through both the direct modulation of the ?-stacking interactions with guanine and the secondary geometric effects that influence the strength and number of hydrogen bonds between guanine and the ethylenediamine linker connecting the arene to the naphthyridine backbone.

Gold catalysis is a convenient tool to oxidatively functionalize alkyne into a range of valuable compounds. In this article, we report a new access to isochroman-4-one and 2H-pyran-3(6H)-one derivatives that involves a gold-catalyzed oxidative cycloalkoxylation of an alkyne in the presence of a pyridine N-oxide. The reaction proceeds under mild conditions, is relatively efficient and exhibits a high functional group compatibility.

We describe the one-pot synthesis of core 2 class branched oligosaccharides initiated by chemo-selective glycosylation of silyl ether. Glycosylation of 6-O-silyl-4-benzyl-2-azido-thiogalactoside with glycosyl fluoride provided selectively 6-glycosylated thioglycoside without both O-glycosylation at the 3 position and S-glycosylation. Subsequent coupling of galactosyl fluoride and amino acids afforded the protected branched oligosaccharides in good yields.

Be a powerful technique for convenient detection of pH change in living cells, especially at subcellular level, fluorescent probes has attracted more and more attention. In this work, we designed and synthesized three rhodamine lactam modulated fluorescent probes RS1, RS2 and RS3, which all respond sensitively toward weak acidity (pH range 4-6) via the photophysical property in buffer solution without interference from the other metal ions, and they also show ideal pKa values and excellent reversibility. Particularly, by changing the lone pair electrons distribution of lactam-N atom with different conjugations, RS2 and RS3 exhibit high quantum yield, negligible cytotoxicity and excellent permeability. They are suitable to stain selectively lysosomes of tumor cells and monitor its pH changes sensitively via optical molecular imaging. The above findings suggest that the probes we designed could act as ideal and easy method for investigating the pivotal role of H+ in lysosomes and are potential pH detectors in disease diagnosis through direct intracellular imaging.

The paper contains results of statistical and chemometric analysis for 15 thiourea derivatives containing the 3-amino-1,2,4-triazole moiety and characterized by antimicrobial activity against Staphylococcus aureus (NCTC 4163, ATCC 25923, ATCC 6538, ATCC 29213), Staphylococcus epidermidis (ATCC 12228) bacteria, as well as by low cytotoxicity (or lack thereof) against infected MT-4 cells. Multiple regression and cluster analysis were employed to perform the study. The research enabled obtaining linear relationships connected with three molecular descriptors SA, eta, logP. The conducted chemometric analyses indicate that the increase in activity against the studied strains is closely related to the type and position of substituent in a phenyl ring.

Bacillus sp. are well-known biocontrol agents against various fungal plant pathogens. The present work was conducted for characterization of antagonistic Bacillus sp., isolated from tomato rhizosphere, and its control mechanisms against Fusarium oxysporum f. sp. lycopersici. A collection of 49 Bacillus isolates was obtained from the rhizosphere of tomato plants from infested field. Dual culture antagonism assay was carried out to assess the potential role of the strains against the pathogen. The evaluation of the strains was done for their antifungal ability and plant growth promoting properties including beta-1,3-glucanase, protease, chitinase, ammonia, siderophore, hydrogen cyanide, IAA and biofilm formation. Strain B44, identified as Bacillus sp. based on ribotyping (Accession no. MG779639), which exhibited maximum number of antifungal properties tested, was selected for further study. The strain was capable of producing hydrolytic enzymes such as beta-1,3-glucanase (15.61 U ml?1 min?1), protease (1608.15 U ml?1 min?1), and chitinase (129 U ml?1 min?1), volatiles and non-volatile metabolites. Volatiles were extracted by solid phase micro extraction (SPME) technique. The major compounds identified by GC-MS analysis were 1,2-benzenedicarboxylic acid (23.99%), 6-undecylamine (6.61%), 2-methyloctacosane (5.91%), 9-octadecenoic acid (5.13%) and 1-tetradecanamine, N,N-dimethyl (5.05%). The prominent compounds identified by UPLC-MS were tert-butyl difluorophosphine (31.45%), 5-(4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (14.76%), 6-bromo-4-tert-butyl-1,1-dimethyl-1,2-dihydronaphthalene (8.35%), 2-amino-N-butyl-1,8-naphthyridine-3-carboxamide (6%), N,N-diethyl-2-[(ethylamino)methyl]-3-phenyloxirane-2-sulfonamide (5.12%). The isolate showed approx. 36% reduction in disease incidence in tomato plant under green house conditions and could serve as an efficient agent for biocontrol of wilt disease in tomato.
