Design of glycosyltransferase inhibitors targeting human O-GlcNAc transferase (OGT)

Inhibition of glycosyltransferases requires the design of neutral inhibitors to allow cell permeation in contrast to their natural dianionic substrates. O-GlcNAc transferase (OGT) is a key enzyme involved in dynamic glycosylation of cytosolic and nuclear proteins in competition with phosphorylation. Designing OGT inhibitors is of prime interest for the better understanding of its biological implications. Introduction of a pyridine moiety as a pyrophosphate surrogate was evaluated, which provided moderate in vitro inhibition of OGT. Docking studies highlighted some key features for the binding of the designed inhibitors to the catalytic site of OGT where the carbohydrate moiety did not occupy its natural position but rather turned away and pointed to the solvent outside the catalytic pocket. Further investigation with cellular assays did not provide inhibition of OGT. This lack of OGT inhibition was rationalized with a permeation assay which revealed the sequestration of the inhibitors at the membrane. This journal is the Partner Organisations 2014.

Discovery and SAR study of piperidine-based derivatives as novel influenza virus inhibitors

A series of piperidine-based derivatives were identified as novel and potent inhibitors of the influenza virus through structural modification of a compound that was selected from a high-throughput screen. Various analogues were synthesized and confirmed as inhibitors. The structure-activity relationship (SAR) studies suggested that the ether linkage between the quinoline and piperidine is critical for the inhibitory activity. The optimized compound tert-butyl 4-(quinolin-4-yloxy)piperidine-1-carboxylate 11e had an excellent inhibitory activity against influenza virus infection from a variety of influenza virus strains, with EC50values as low as 0.05 muM. The selectivity index value (SI = MLD50/EC50) of 11e is over 160 000 based on cytotoxicity, measured by MTT assays of three cell lines. We carried out a time-of-addition experiment to delineate the mechanism of inhibition. The result indicates that 11e interferes with the early to middle stage of influenza virus replication.

SiRNA delivery into tumor cells by cationic cholesterol derivative-based nanoparticles and liposomes

Previously, we reported that cationic nanoparticles (NP) composed of diamine-type cholesteryl-3-carboxamide (OH-Chol, N-(2-(2-hydroxyethylamino)ethyl)cholesteryl-3-carboxamide) and Tween 80 could deliver small interfering RNA (siRNA) with high transfection efficiency into tumor cells. In this study, we synthesized new diamine-type cationic cholesteryl carbamate (OH-C-Chol, cholesteryl (2-((2-hydroxyethyl)-amino)ethyl)carbamate) and triamine-type carbamate (OH-NC-Chol, cholesteryl (2-((2-((2-hydroxyethyl)-amino)ethyl)amino)ethyl)carbamate), and prepared cationic nanoparticles composed of OH-C-Chol or OHNC-Chol with Tween 80 (NP-C and NP-NC, respectively), as well as cationic liposomes composed of OH-CChol or OH-NC-Chol with 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) (LP-C and LP-NC, respectively) for evaluation of their possible use as siRNA delivery vectors. LP-C and LP-NC/siRNA complexes (lipoplexes) exhibited larger gene silencing effects than NP-C and NP-NC/siRNA complexes (nanoplexes), respectively, in human breast tumor MCF-7 cells, although the NP-C nanoplex showed high association with the cells. In particular, LP-NC lipoplex could induce strong gene suppression, even at a concentration of 5 nM siRNA. From these results, cationic liposomes composed of OH-NC-Chol and DOPE may have potential as gene vectors for siRNA transfection to tumor cells.

Synthesis, gp120 binding and anti-HIV activity of fatty acid esters of 1,1-linked disaccharides

Inspired by the anti-human immunodeficiency virus (HIV) activity of analogues of beta-galactosylceramide (GalCer), a set of mono- and di-saccharide fatty acid esters were designed as GalCer mimetics and their binding to the V3 loop peptide of HIV-1 and anti-HIV activity evaluated. 1,1-linked Gal-Man and Glu-Man disaccharides with an ester on the Man subunit bound the V3 loop peptide and inhibited HIV infectivity in single round infection assays with the TZM-bl cell line. IC50’s were in the 50 muM range with no toxicity to the cells at concentrations up to 200 muM. These compounds appear to inhibit virus entry at early steps in viral infection since they were inactive if added post viral entry. Although these compounds were found to bind to the V3 loop peptide of gp120, it is not clear that this interaction is responsible for their anti-HIV activity because the relative binding affinity of closely related analogues did not correlate with their antiviral behavior. The low cytotoxicity of these 1,1-linked disaccharide fatty acid esters, combined with the easy accessibility to structurally diverse analogues make these molecules attractive leads for new topical anti-viral agents.
