Terpolymerization kinetics of amino acid N-carboxy anhydrides

Based on their versatility with respect to amino acid type and sequence, polypeptides have become attractive for a number of biological applications such as drug delivery, biomineralization, and drugs. N-carboxy anhydride (NCA) polymerization is a convenient way to rapidly prepare high-molecular weight polypeptides with good control over molecular weight and polydispersity. However, the kinetics of the incorporation of NCA monomers into copolypeptides during random copolymerization are poorly understood. Here, kinetic data is presented that allows insight into the NCA polymerization of a terpolymer composed of three commercially relevant amino acids, namely, glutamic acid, lysine, and tyrosine. Furthermore, kinetic data and copolymerization parameters from the copolymerization of binary mixtures of these three amino acid NCAs is used to make predictions of the terpolymer composition. This study provides access to the information necessary to prepare functional copolypeptides with better-defined sequence architecture that will be essential for the future development of polypeptide-based materials.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1676-86-4, help many people in the next few years.category: oxazolidine

Sulfonamide-directed gold-catalyzed [2+2+2]-cycloadditions of nitriles with two discrete ynamides to construct 2,4-diaminopyridine cores

Gold-catalyzed [2+2+2]-cycloadditions of two discrete ynamides and one nitrile afford 2,4-diaminopyridine derivatives that are not readily prepared from typical low-valent-metal catalysts. Our mechanistic analysis reveals that the reaction chemoselectivity is controlled by the types of sulfonamides of ynamides.

Can We Make Small Molecules Lean? Optimization of a Highly Lipophilic TarO Inhibitor

We describe our optimization efforts to improve the physicochemical properties, solubility, and off-target profile of 1, an inhibitor of TarO, an early stage enzyme in the biosynthetic pathway for wall teichoic acid (WTA) synthesis. Compound 1 displayed a TarO IC50 of 125 nM in an enzyme assay and possessed very high lipophilicity (clogP = 7.1) with no measurable solubility in PBS buffer. Structure-activity relationship (SAR) studies resulted in a series of compounds with improved lipophilic ligand efficiency (LLE) consistent with the reduction of clogP. From these efforts, analog 9 was selected for our initial in vivo study, which in combination with subefficacious dose of imipenem (IPM) robustly lowered the bacterial burden in a neutropenic Staphylococci murine infection model. Concurrent with our in vivo optimization effort using 9, we further improved LLE as exemplified by a much more druglike analog 26.

Synthesis of diaminopimelic acid containing peptidoglycan fragments and tracheal cytotoxin (TCT) and investigation of their biological functions

Bacterial cell wall peptidoglycan (PGN) is a potent immunostimulator and immune adjuvant. The PGN of Gram-negative bacteria and some Gram-positive bacteria contain meso-diaminopimelic acid (meso-DAP), and we have recently shown that the intracellular protein Nodi is a PGN receptor and recognizes DAPcontaining peptides. In this study, we achieved the synthesis of DAP-containing PGN fragments, including the first chemical synthesis of tracheal cytotoxin (TCT), GlcNAc-(beta1-4)-(anhydro) Mur-NAc-L-Ala-gamma-D-Glu-meso- DAP-D-Ala, and a repeating-unit of DAP-type PGN, GlcNAc-(beta1-4)-MurNAc-L- Ala-gamma-D-Glu-meso-DAP-D-Ala. For the synthesis of PGN fragments, we first established a new synthetic method for an orthogonally protected meso-DAP derivative, and then we constructed the glycopeptide structures. The ability of these fragments to stimulate human Nodi, as well as differences in Nodi recognition of the variety of synthesized ligand structures were examined. The results showed that the substitution of the N terminus of iE-DAP is necessary for stronger Nodi recognition, but the structure of the substituent seems not to be strictly recognized. The importance of the carboxyl group at the 2-position of DAP for human Nod1 stimulation was also shown.

Discovery of novel benzoxazinones as potent and orally active long chain fatty acid elongase 6 inhibitors

A series of benzoxazinones was synthesized and evaluated as novel long chain fatty acid elongase 6 (ELOVL6) inhibitors. Exploration of the SAR of the UHTS lead 1a led to the identification of (S)-1y that possesses a unique chiral quarternary center and a pyrazole ring as critical pharmacophore elements. Compound (S)-1y showed potent and selective inhibitory activity toward human ELOVL6 while displaying potent inhibitory activity toward both mouse ELOVL3 and 6 enzymes. Compound (S)-1y showed acceptable pharmacokinetic profiles after oral dosing in mice. Furthermore, (S)-1y significantly suppressed the elongation of target fatty acids in mouse liver at 30 mg/kg oral dosing. 2009 American Chemical Society.
