Homogeneously glycosylated proteins are important targets for fundamental research and for biopharmaceutical development. The use of unnatural protein-glycan linkages bearing structural similarity to their native counterparts can accelerate the synthesis of glycoengineered proteins. Here we report an approach toward generating homogeneously glycosylated proteins that involves chemical attachment of aminooxy glycans to recombinantly produced proteins via oxime linkages. We employed the recently introduced aldehyde tag method to obtain a recombinant protein with the aldehyde-bearing formylglycine residue at a specific site. Complex aminooxy glycans were synthesized using a new route that features N-pentenoyl hydroxamates as key intermediates that can be readily elaborated chemically and enzymatically. We demonstrated the method by constructing site-specifically glycosylated variants of the human growth hormone.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 100361-18-0, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 100361-18-0, Name is 7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, molecular formula is C12H8ClFN2O3

New pyrrolidine derivatives, which bear an alkyloxime substituent in the 4-position and an aminomethyl substituent in the 3-position of the pyrrolidine ring, have been synthesized and coupled with various quinolinecarboxylic acids to produce a series of new fluoroquinolone antibacterials. These fluoroquinolones were found to possess potent antimicrobial activity against both Gram-negative and Gram-positive organisms, including methicillin resistant Staphylococcus aureus (MRSA). Variations at the C-8 position of the quinolone nucleus included fluorine, chlorine, nitrogen, methoxy, and hydrogen atom substitution. The activity imparted to the substituted quinolone nucleus by the C-8 substituent was in the order F (C5-NH2) > F (C5-H) > naphthyridine > Cl = OMe = H against Gram-positive organisms. In the case of Gram-negative strains, activity was in the order F (C5-NH2) > naphthyridine = F (C5-H) > H > Cl > OMe. The advantages provided by the newly introduced oxime group of the quinolones were clearly demonstrated by their comparison to a desoximino compound 30. In addition, the oxime moiety greatly improved the pharmacokinetic parameters of the novel quinolones. Among these compounds, compound 20 (LB20304) showed the best in vive efficacy and pharmacokinetic profile in animals, as well as good physical properties. The MICs (mug/mL) of LB20304, compound 30, and ciprofloxacin against several test organisms are as follows: S. aureus 6538p (0.008, 0.031, and 0.13), methicillin resistant S. aureus 241 (4, 16, and 128), Streptococcus epidermidis 887E (0.008, 0.016, and 0.13), methicillin resistant S. epidermidis 178 (4, 32, and 128), Enterococcus faecalis 29212 (0.063, 0.13, and 1), Pseudomonas aeruginosa 1912E (0.25, 0.5, and 0.13), Escherichia coli 3190Y (0.008, 0.016, and 0.008), Enterobacter cloacae P99 (0.008, 0.031, and 0.008), Actinobacter calcoaceticus 15473 (0.063, 0.13, and 0.25). On the basis of these promising results, LB20304 was selected as a candidate for further evaluation.

The tachykinin NK2 receptor is widel y distributed in the peripheral and central nervou s system. It mediates numerous pharmacologi cal effects of neurokinin A, suggesting that the tachykinin NK2 receptor may be possible target for new therapeutics. Many effor ts to identify and cha racterize selective antagonists of thi s receptor have been undertaken and several antagonists of both peptide and nonpeptide nature have been disclosed. Among th ese compounds, nepadutant, a peptide-based antagonist, and saredutant, a nonpeptide antagoni st, are certainly among the most potent compounds. These two antagonists combine high affinity for the human tachykinin NK2 receptor with strong antagonist activities in a large variety of in vitro and in vivo pharmacological models. Contrary to nepadutant, saredutant has been shown to be orally active. In addition to th eir potent acti vitie s in the airways they show potent inhibitory activities in visceral nociception suggesting that a tach ykinin NK2 receptor antagonist may be useful for the tre atment of functional gastrointestinal disorders such as irritable bowel syndrome. With the use of saredutant, major progress has also been made in the understanding of the role of brain tachykinin NK2 receptors. Contrary to nepadutant, saredutant is centrally active and shows antidepressant/anxiolytic activity.

PEGylated chitosan-based nanoparticles offer attractive platforms for siRNA cocktail delivery into tumors. Still, therapeutic efficacy requires us to select a rational combination of siRNAs and an efficient tumor delivery after systemic administration. Here, we showed that non-covalent PEGylation of chitosan-based nanoparticles loaded with siRNA targeting two key transporters of energy fuels for cancer cells, namely the lactate transporter MCT1 and the glutamine transporter ASCT2, could lead to significant antitumor effects. As a ligand, we tested variations of the prototypical RGD peptidomimetic (RGDp). A higher siRNA delivery was obtained with naphthyridine-containing RGDp randomly conjugated on the PEG chain by clip photochemistry and the use of a lipophilic linker than when using traditional chain-end grafting and RGDp with a hydrophilic linker. The antiproliferative effects resulting from ASCT2 and MCT1 silencing were validated separately in vitro in conditions mimicking specific metabolic profiles of cancer cells and in vivo upon concomitant delivery. The combination of those siRNA and the selected components of targeted RGDp nanoparticles led to a dramatic tumor growth inhibition upon peri-tumoral but also systemic administration in mice. Altogether these data emphasize the convenience of using non-covalent PEGylated chitosan particles to produce sheddable stealth protection compatible with an efficient siRNA delivery in tumors.

A pyrene-based colorimetric and fluorescent pH probe with large Stokes shift (145 nm) was developed. PNY afforded a pKa of 2.98 and responded linearly to minor pH changes within the range of 2.43 and 3.71. In addition, PNY could be used for detecting H+ with high sensitivity and selectivity, showing colorimetric and fluorometric dual-modal responses with short response time. Furthermore, PNY had good photostability, excellent reversibility and cell membrane permeability. Significantly, PNY could image acidic pH in A549 cells and visualized extreme acidity in E. coli cells.
