(Equation Presented) The 1,3-dipolar cycloadditions of C-glycosyl nitrile oxides and acetylenes to an alkyne and an azide, respectively, bearing a masked glycinyl moiety furnished disubstituted isoxazoles and triazoles. Unveiling the glycinyl group in these cycloadducts afforded C-glycosyl alpha-amino acids in which the two bioactive entities were tethered through rigid five-membered heterocycles. Optimized entries to the same compounds involved the use of unmasked but protected alkyne- and azide-containing amino acids as the partners of 1,3-dipolar cycloadditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C12H21NO4, you can also check out more blogs about147959-19-1

The enzymatic resolution of the N-phenylacetyl derivative of racemic homoserine lactone with penicillin G acylase immobilized on Eupergit C gave (R)-(+)-alpha-amino-gamma-butyrolactone and (S)-(-)-alpha-N- phenylacetamido-gamma-butyrolactone in high enantiomeric purity (ee >99%) and 46-47% yields for each enantiomer. The enantiomers were converted into azasugars 1,4-dideoxyallonojirimycin and 1,4-dideoxymannojirimycin using Wittig olefination, catalytic ring-closing metathesis (RCM), and stereoselective dihydroxylation with OsO4 in 29% overall yield over 11 high yielding steps. Enzyme inhibition studies showed that 1,4-dideoxyallonojirimycin is a better beta-glucosidase inhibitor (IC50 32.4 muM toward beta-glucosidase from almonds) and a better beta-galactosidase inhibitor (IC50 5.9 mM for beta-galactosidase from Aspergillus oryzae) than 1,4-dideoxymannojirimycin (IC50 2.86 mM and 12.5 mM for beta-glucosidase and beta-galactosidase, respectively).

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.

Synthesis of 2-aminosuberic acid derivatives as components of some histone deacetylase inhibiting cyclic tetrapeptides

A new synthesis of the important amino acid 2-aminosuberic acid from aspartic acid is reported. The methodology involves the alternate preparation of (S)-2-aminohept-6-enoate ester as a building block and its diversification through a cross-metathesis reaction to prepare the title compounds. The utility of the protocol is demonstrated through the preparation of three suberic acid derivatives of relevance to the design and the synthesis of peptides of biological relevance.

Bifunctional Tripeptide with a Phosphonic Acid as a Br°nsted Acid for Michael Addition: Mechanistic Insights

Enamine catalysis is a widespread activation mode in the field of organocatalysis and is often encountered in bifunctional organocatalysts. We previously described H-Pro-Pro-pAla-OMe as a bifunctional catalyst for Michael addition between aldehydes and aromatic nitroalkenes. Considering that opposite selectivities were observed when compared to H-Pro-Pro-Glu-NH2, an analogue described by Wennemers, the activation mode of H-Pro-Pro-pAla-OMe was investigated through kinetic, linear effect studies, NMR analyses, and structural modifications. It appeared that only one bifunctional catalyst was involved in the catalytic cycle, by activating aldehyde through an (E)-enamine and nitroalkene through an acidic interaction. A restrained tripeptide structure was optimal in terms of distance and rigidity for better selectivities and fast reaction rates. Transition-state modeling unveiled the particular selectivity of this phosphonopeptide.

Meta-substituted benzofused macrocyclic lactams as zinc metalloprotease inhibitors

The design, synthesis, and biochemical profile of meta-substituted benzofused macrocyclic lactams are described. The meta-substituted benzofused macrocyclic lactams were designed to have a degree of flexibility allowing the amide bond to occupy two completely different conformations while maintaining sufficient rigidity to allow for strong interaction between enzyme and inhibitor. Using TFIT, a novel molecular superimposition program, it was shown that the meta analogs could be readily superimposed onto our ACE inhibitor template whereas no low-energy superimpositions of the ortho- substituted macrocycles could be found. The macrocycles were prepared by tethering aldehyde 1 derived from S-glutamic acid or S-aspartic acid to a meta-substituted phosphonium bromide 2. Homologation to a monocarboxylic acid methyl ester malonate followed by deprotection and cyclization gave the macrocyclic frame. Further manipulation gave the desired compounds. Unlike the ortho-substituted benzofused macrocyclic lactams described in the previous paper which are selective NEP inhibitors, the meta-substituted compounds are dual inhibitors of both NEP and ACE. The most potent member of this new series, compound 16a, inhibited both enzymes with an IC50 = 8 nM in NEP and 4 nM in ACE.
