Directing/protecting groups mediate highly regioselective glycosylation of monoprotected acceptors

A directing/protecting group designed for regioselective functionalization of partially-protected glucopyrannosides has been successfully used to prepare disaccharides in high yields. Most importantly, it has been demonstrated that highly regioselective and stereoselective glycosylation can be achieved when disarmed donors are employed. This study demonstrates the ability of directing/protecting group to induce regioselective glycosylation of carbohydrates and opens the field to the design of other DPGs for other monosaccharides.

3-(Dimethylamino)-1-propylamine: A cheap and versatile reagent for removal of byproducts in carbohydrate chemistry

Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such as benzoyl chloride, tosyl chloride, and 2,2,2-trifluoro-N-phenylacetimidoyl chloride. The deacylation reaction could be conducted in moist THF and did not require chromatographic purification since an acidic wash was sufficient to remove excess reagent and the formed byproduct.

Discovery of GS-9669, a thumb site II non-nucleoside inhibitor of NS5B for the treatment of genotype 1 chronic hepatitis C infection

Investigation of thiophene-2-carboxylic acid HCV NS5B site II inhibitors, guided by measurement of cell culture medium binding, revealed the structure-activity relationships for intrinsic cellular potency. The pharmacokinetic profile was enhanced through incorporation of heterocyclic ethers on the N-alkyl substituent. Hydroxyl groups were incorporated to modulate protein binding. Intrinsic potency was further improved through enantiospecific introduction of an olefin in the N-acyl motif, resulting in the discovery of the phase 2 clinical candidate GS-9669. The unexpected activity of this compound against the clinically relevant NS5B M423T mutant, relative to the wild type, was shown to arise from both the N-alkyl substituent and the N-acyl group.

Discovery of small-molecule interleukin-2 inhibitors from a DNA-encoded chemical library

Libraries of chemical compounds individually coupled to encoding DNA tags (DNA-encoded chemical libraries) hold promise to facilitate exceptionally efficient ligand discovery. We constructed a high-quality DNAencoded chemical library comprising 30 000 drug-like compounds; this was screened in 170 different affinity capture experiments. High-throughput sequencing allowed the evaluation of 120 million DNA codes for a systematic analysis of selection strategies and statistically robust identification of binding molecules. Selections performed against the tumor-associated antigen carbonic anhydrase IX (CA IX) and the pro-inflammatory cytokine interleukin-2 (IL-2) yielded potent inhibitors with exquisite target specificity. The binding mode of the revealed pharmacophore against IL-2 was confirmed by molecular docking. Our findings suggest that DNA-encoded chemical libraries allow the facile identification of drug-like ligands principally to any protein of choice, including molecules capable of disrupting high-affinity protein-protein interactions.

Synthesis of cellobiose-containing oligosaccharides by intermolecular transglucosylation of cyclodextrin glycosyltransferase from Paenibacillus sp. A11

Intermolecular transglucosylation of cyclodextrin glycosyltransferase (CGTase) was investigated for its use in oligosaccharide synthesis. From the kinetic parameters of the CGTase-catalyzed transglucosylation reaction, using beta-cyclodextrin (beta-CD) as the glucosyl donor and various saccharides or derivatives as acceptors, the efficient acceptors of the Paenibacillus sp. A11 enzyme were glucose, sorbose, lactose and cellobiose. Amongst these acceptors, cellobiose showed the highest kcat/Km value. The transglucosylation yields of the reactions for cellobiose, sorbose and glucose acceptors were 78, 57 and 54%, respectively, making cellobiose the most efficient acceptor of the tested saccharides in coupling with beta-CD. The optimal condition for the coupling reaction was determined as: 2% (w/v) beta-CD and 0.5% (w/v) cellobiose, incubated with 64 U/mL of CGTase at 30 C for 2 h. Two main transfer products detected by HPLC, PC1 and PC2, with retention times of 3.81 and 4.42 min, respectively, and a product ratio of 3:1, had a molecular mass of 504 and 666 Da, respectively, as analyzed by mass spectrometry. The structures suggested by NMR were a trisaccharide and a novel tetrasaccharide-containing cellobiose of the structures glc (alpha1 ? 4) glc (beta1 ? 4) glc and glc (alpha1 ? 4) glc (alpha1 ? 4) glc (beta1 ? 4) glc, respectively. The products were found to be resistant to hydrolysis by alpha-amylase.

Discovery of novel 2-aminopyridine-3-carboxamides as c-Met kinase inhibitors

A series of 2-aminopyridine-3-carboxamide derivatives against c-Met were designed and synthesized by employing bioisosteric replacement of heterocyclic moieties with the amide bond. The structure-activity relationship (SAR) at various positions of the scaffold was explored. In this study, a promising compound (S)-24o with a c-Met IC50 of 0.022 muM was identified. The compound exhibited dose-dependent inhibition of the phosphorylation of c-Met as well as downstream signaling in EBC-1 cells. Furthermore, the interactive binding model of (S)-24o with c-Met was elucidated by virtue of a molecular modeling study.
