Simple and large-scale production of N-acetylneuraminic acid from N- acetyl-D-glucosamine and pyruvate using N-acyl-dglucosamine 2-epimerase and n-acetylneuraminate lyase

N-Acetylneuraminate lyase and N-acyl-D-glucosamine 2-epimerase had been cloned and over-expressed in Escherichia coli. Simultaneous use of these two enzymes and feeding of appropriate amounts of pyruvate to the reaction mixture made possible the high conversion of N-acetylneuraminic acid (Neu5Ac) from N-acetyl-D-glucosamine (GlcNAc) with a 77% conversion rate on a molar basis. As a result, 29 kg of Neu5Ac was obtained from 27 kg of GlcNAc. The product was recovered by direct crystallization, and verified as identical to authentic Neu5Ac.

Bromodimethylsulfonium bromide-silver triflate: A new powerful promoter system for the activation of thioglycosides

Bromodimethylsulfonium bromide (BDMS) in combination with silver triflate provides a very efficient thiophilic promoter system, capable of activating both “disarmed” and “armed” thioglycosides for glycosidic bond formation. The usefulness of this new promoter is illustrated by a successful reactivity-based one-pot oligosaccharide assembly.

Discovery of Novel Spiroindoline Derivatives as Selective Tankyrase Inhibitors

The canonical WNT pathway plays an important role in cancer pathogenesis. Inhibition of poly(ADP-ribose) polymerase catalytic activity of the tankyrases (TNKS/TNKS2) has been reported to reduce the Wnt/beta-catenin signal by preventing poly ADP-ribosylation-dependent degradation of AXIN, a negative regulator of Wnt/beta-catenin signaling. With the goal of investigating the effects of tankyrase and Wnt pathway inhibition on tumor growth, we set out to find small-molecule inhibitors of TNKS/TNKS2 with suitable drug-like properties. Starting from 1a, a high-throughput screening hit, the spiroindoline derivative 40c (RK-287107) was discovered as a potent TNKS/TNKS2 inhibitor with >7000-fold selectivity against the PARP1 enzyme, which inhibits WNT-responsive TCF reporter activity and proliferation of human colorectal cancer cell line COLO-320DM. RK-287107 also demonstrated dose-dependent tumor growth inhibition in a mouse xenograft model. These observations suggest that RK-287107 is a promising lead compound for the development of novel tankyrase inhibitors as anticancer agents.

Half-Sandwich Osmium(II) Complexes with Bidentate N,N-Chelating Ligands and Their Use in the Transfer Hydrogenation of Ketones

The reaction of appropriate N,N-bidentate ligands with the [(eta6-p-cymene)Os(mu-Cl)Cl]2dimer (p-cymene = C10H14), followed by metathesis reaction with NH4PF6, gave the new osmium(II) arene complex salts [(eta6-p-cymene)OsCl(C5H4N-2-CH=N?R)]PF6, where [R = tert-butyl (1), isopropyl (2), 2,6-dimethylphenyl (3), or 2,6-diisopropylphenyl (4)]. The dimer was also reacted with the N,N?-bidentate ligands di-(2-pyridyl)amine (5), 4-phenyl-3,6-di(2-pyridyl)pyridazine (6), 4,4?-di-tert-butyl-2, 2?-bipyridine (7), and 5,5?-dimethyl-2,2?-bipyridine (8). In addition, the reaction of the precursor [(eta6-C6H6)Os(mu-Cl)Cl]2with the N,N?-bidentate ligands gave [(eta6-C6H6)OsCl(N,N)]2where N,N = 4,4?-di-tert-butyl-2,2?-bipyridine (9), 5,5?-dimethyl-2,2?-bipyridine (10), 3,6-bis(2-pyridyl)-4-phenyl pyridazine (11), or di-(2-pyridyl)amine (12). The compounds were characterized by using1H and13C NMR, UV/Vis, FTIR spectroscopy and elemental analysis. The single-crystal X-ray structures for compounds 1, 4, 8, 10, 11, and 12 showed that the osmium(II) complexes adopted the classical three-legged piano stool geometry. These osmium(II) compounds were found to be effective catalysts for the transfer hydrogenation of ketones into alcohols with NaOH as base and 2-propanol as the solvent and hydrogen source. A range of cyclic, aromatic, and aliphatic ketones was studied and good turnover numbers achieved.
