Gram scale synthesis of the glucuronide metabolite of ABT-724

A gram scale synthesis of the glucuronide metabolite of ABT-724 is reported. Glycosidic coupling between a trichloroacetimidate glucuronyl donor and a Cbz-protected hydroxypyridylpiperazine glycosyl acceptor is the key step in the synthesis, since attempts to directly glucuronicrossed d signate the aglycon, aglycon derivatives, and other truncated glycosyl acceptors were unsuccessful. The route was used to produce 2.1 g of metabolite in eight steps from 2-chloro-5-hydroxypyridine in 21% overall yield.

Design and synthesis of O-GlcNAcase inhibitors via ‘click chemistry’ and biological evaluations

Protein O-GlcNAcylation has been shown to play an important role in a number of biological processes, including regulation of the cell cycle, DNA transcription and translation, signal transduction, and protein degradation. O-GlcNAcase (OGA) is responsible for the removal of O-linked beta-N-acetylglucosamine (O-GlcNAc) from serine or threonine residues, and thus plays a key role in O-GlcNAc metabolism. Potent OGA inhibitors are useful tools for studying the cellular processes of O-GlcNAc, and may be developed as drugs for the treatment neurodegenerative diseases. In this study, Cu(I)-catalyzed ‘Click’ cycloaddition reactions between glycosyl azides and alkynes were exploited to generate inhibitory candidates of OGA. Enzymatic kinetic screening revealed that compound 7 was a potent competitive inhibitor of human O-GlcNAcase (Ki = 185.6 muM). Molecular docking simulations of compound 7 into CpOGA (Clostridium perfringens OGA) suggested that strong pi-pi stacking interaction between the compound and W490 considerably contributed to improving the inhibitory activity.

On the effect of the aglycon structure of three aryl beta-D-galactosides on the yield and the regioselecttvity of the transglycolytic synthesis of N-acetyllactosamine

We examined the effect as donors of three aryl beta-D-galactosides (i.e. p-nitrophenyl beta-D-galactopyranoside, o-nitrophenyl beta-D-galactopyranoside and phenyl beta-D-galactopyranoside) on the regioselectivity and the yield of the synthesis of N-acetyllactosamine obtained from the transglycosylation reaction catalyzed by a crude preparation of beta-D-galactosidase from Bacillus circulans at 25C, 37C and 55C, respectively. Using p-nitrophenyl beta-D-galactopyranoside the reaction results were fully regiospecific at all the temperatures considered: the maximum molar yield (74%) was obtained at an incubation temperature of 55C Using o-nitrophenyl beta-D-galactopyranoside as the donor the reaction was still highly regioselective and the maximum molar yield (50%) was achieved at an incubation temperature also of 55C. Using phenyl beta-D-galactopyranoside transglycolytic products appear only at an incubation temperature of 55C but at very low molar yield (about 14%) and lower regioselectivity.

A simple and facile synthesis of the fused 6-6-5 ring system, i.e., 1,2,3,3a,4,9b-hexahydrocyclopenta[c][1]benzopyrans, was achieved through the intramolecular [4+2] cycloaddition of o-quinonemethides generated from 2-(1- hydroxy-5-alkenyl)phenol derivatives under acidic conditions. In general, cis-fused tricyclic compounds of 6-6-5 ring system were obtained as the major products.
