Glycosylated lanthanide cyclen complexes as luminescent probes for monitoring glycosidase enzyme activity
Burke, Helen M.,Gunnlaugsson, Thorfinnur,Scanlan, Eoin M.
, p. 9133 - 9145 (2016/10/07)
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.

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.

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.

A versatile glycosynthase (TnG-E338A) with strikingly broad substrate scope has been developed from Thermus nonproteolyticus β-glycosidase (TnG) by using site-directed mutagenesis. The practical utility of this biocatalyst has been demonstrated by the facile generation of a small library containing various oligosaccharides and a steroidal glycoside (total 25 compounds) in up to 100 % isolated yield. Moreover, an array of eight gluco-oligosaccharides has been readily synthesized by the enzyme in a one-pot, parallel reaction, which highlights its potential in the combinatorial construction of a carbohydrate library that will assist glycomic and glycotherapeutic research. Significantly, the enzyme provides a means by which glycosynthase technology may be extended to combinatorial chemistry.
Solvent-free mechanochemical synthesis of aryl glycosides
Patil, Premanand Ramrao,Ravindranathan Kartha
experimental part, p. 411 - 419 (2009/04/11)
Aryl glycosides have been prepared from a range of readily available glycosyl halides by a solvent-free mechanochemical procedure employing a planetary ball mill in excellent yields. Besides being a solvent-free reaction, the procedure has been successful in eliminating the need for employing any phase-transfer catalyst in the reaction. Copyright Taylor & Francis Group, LLC.

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.
