Glycosylated lanthanide cyclen complexes as luminescent probes for monitoring glycosidase enzyme activity

The development of synthetic chemical probes for the detection of enzymes is extremely important for biological, medicinal, and industrial applications. Here we report the synthesis of an array of novel glycosylated Tb(iii) complexes, their photophysical properties in solution, and their ability to function as luminescent probes for observing glycosidase enzyme activity in real time. Our initial studies into the application of these complexes for the detection of the Concanavalin A (ConA) lectin is also reported, highlighting the broad scope of these novel chemical probes.

Synthesis and inhibitory activity evaluation of 2,6-disubstituted purine derivatives

A series of novel 2,6-disubstituted purine derivatives were designed and synthesized from 2,6-dichloropurine. The structures of target compounds were determined by 1H-NMR, 13C-NMR, and HRMS. The synthesized compounds were evaluated for their inhibitory activities against lung cancer cell lines of A549 and liver cancer cell lines of Bel-7402. 2-(4-Benzyloxy-phenylamino)-6-(cyclohexylamino)purine(3), 2-(4-chloro-phenylamino)-6-(n-butylamino)purine (5), 2-(4-morpholinoamino)-6-(4-hydroxy-phenylamino)purine (9), and 2-(4-O-galactosyl-phenylamino)-6-(cyclohexylamino)purine (12) exhibited moderate inhibitory activity.

Glycosylated tris-bipyridine ferrous complexes to provide dynamic combinatorial libraries for probing carbohydrate-carbohydrate interactions

2,2-Bipyridines having β-lactoside, β-d-glucoside, β-d-galactoside, and N-acetyl-β-d-glucosaminide were prepared and then, complexed with ferrous ion to afford trivalent glycoclusters having tris-bipyridine ferrous complex cores. Each glycocluster provides a dynamic combinatorial library composed of four diastereomeric stereoisomers (Δmer, Δfac, Λmer, and Λfac) whose ratios depend on their relative stabilities. CD spectral analyses of these glycoclusters showed that various cations (Na+, Mg2+, K+ or Ca2+) enriched Δ-forms of the glycocluster having β-lactosides and N-acetyl-β-d-glucosaminides possibly by cations-induced intramolecular carbohydrate-carbohydrate interactions.

Importance of sialic acid residues illuminated by live animal imaging using phosphorylcholine self-assembled monolayer-coated quantum dots

Glycans are expected to be one of the potential signal molecules for controlling drug targeting/delivery or long-term circulation of biopharmaceuticals. However, the effect of the carbohydrates of artificially glycosylated derivatives on in vivo dynamic d

Syntheses and Transformations of Glycohydrolase Substrates into Protein Conjugates Based on Michael Additions

The glycosyl chloride 1 and bromides 2 and 3 were stereospecifically transformed into p-nitrophenyl glycosides by phase transfer catalysis; these glycohydrolase substrates were reduced and N-acryloylated to afford Michael acceptors which reacted with amine functions of proteins.
