Design, synthesis and in vitro evaluation on glucosamine-6P synthase of aromatic analogs of 2-aminohexitols-6P

The aminosugars are very important structural components of bacterial and fungi cell walls. Glucosamine-6-phosphate synthase (GlmS), which catalyses the first step of the aminosugar biosynthetic pathway i.e. the formation of D-glucosamine-6-phosphate from D-fructose-6- phosphate, is therefore an interesting target in the fight against microorganisms. In this work is described the synthesis of aromatic analogs of 2-amino-2-deoxy-D-glucitol-6- phosphate (ADGP) and its epimer 2-amino-2-deoxy-D-manitol-6-phosphate (ADMP), two important inhibitors of GlmS. The aromatic analogs displayed modest inhibitory activity against GlmS, with IC50 in the mmol L-1 range. 2010 Sociedade Brasileira de Quimica.

Preparation of the beta2-homoselenocysteine derivatives Fmoc-(S)-beta2hSec(PMB)-OH and Boc-(S)-beta2hSec(PMB)- OH for solution and solid-phase peptide synthesis

Fmoc-beta2hSer(tBu)-OH was converted to Fmoc-beta2hSec(PMB)-OH in five steps. To avoid elimination of HSeR, the selenyl group was introduced in the second last step (Fmoc- beta2hSer(Ts)-OAll?Fmoc-beta2hSec(PMB)-OAll). In a similar way, the N-Boc-protected compound was prepared. With the beta2hSe-derivatives, 21 beta2-amino-acid building blocks with proteinogenic side chains are now available for peptide synthesis.

The First Modular Route to Core-Chiral Bispidine Ligands and Their Application in Enantioselective Copper(II)-Catalyzed Henry Reactions

The first modular and flexible synthesis of core-chiral bispidines was achieved by using an “inside-out” strategy. The key intermediate, a NBoc-activated bispidine lactam, was constructed in enantiomerically pure form from a chirally modified beta-amino acid and 2-(acetoxymethyl)acrylonitrile in just five steps and good 48% yield. A simple addition-reduction protocol permitted a highly endo-selective introduction of substituents and, thus, a fast and variable access to 2-endo-substituted and 2-endo,N-fused bi- and tricyclic bispidines. The new diamines were evaluated as the chiral ligands in asymmetric Henry reactions. Excellent enantioselectivities of up to 99% ee and good diastereomeric ratios of up to 86:14 were reached with a copper(II) complex modified by a 2-endo,N-(3,3-dimethylpyrrolidine)-annelated bispidine. Its performance is superior to that of the well-known bispidines (-)-sparteine and the (+)-sparteine surrogate.

Uncatalysed intermolecular aza-Michael reactions

The catalyst-free reactions of activated alkenes with primary and secondary amines were investigated leading to various mono- and di-hydroamination products, the latter being rare and original. These reactions were shown to depend first on the strength of the nucleophile. Temperature and steric hindrance of the reagents were the other key factors controlling the selectivity of these aza-Michael reactions. In spite of their poor nucleophilicities, some N-heterocyclic amines could react with different activated alkenes affording valuable intermediates. Such results tended to demonstrate the hydrogen-bonding interactions between activated alkenes and poly-nitrogen aromatic cycles may control these concerted or fully conjugate aza-Michael additions.

Theranostic Layer-by-Layer Nanoparticles for Simultaneous Tumor Detection and Gene Silencing

Layer-by-layer nanoparticles (NPs) are modular drug delivery vehicles that incorporate multiple functional materials through sequential deposition of polyelectrolytes onto charged nanoparticle cores. Herein, we combined the multicomponent features and tumor targeting capabilities of layer-by-layer assembly with functional biosensing peptides to create a new class of nanotheranostics. These NPs encapsulate a high weight percentage of siRNA while also carrying a synthetic biosensing peptide on the surface that is cleaved into a urinary reporter upon exposure to specific proteases overexpressed in the tumor microenvironment. Importantly, this biosensor reports back on a molecular signature characteristic to metastatic tumors and associated with poor prognosis, MMP9 protease overexpression. This nanotheranostic mediates noninvasive urinary-based diagnostics in mouse models of three different cancers with simultaneous gene silencing in flank and metastatic mouse models of ovarian cancer.

Stereoselective synthesis of unnatural (2S, 3S)-6-hydroxy-4-sphingenine-containing sphingolipids

6-Hydroxy-(4E)-sphingenine-containing sphingolipids are found in mammalian and bacterial membranes and have multiple intra- and intercellular functions. Most sphingolipids contain a (2S,3R)-2-amino-1,3-diol core structure, but only limited examples of unnatural (2S,3S)-2-amino-1,3-diol derivates have so far been reported. Using an underexplored hydrozirconation-transmetalation reaction and an unusual three-step-one-pot deprotection sequence, we were able to synthesize several unnatural (2S,3S)-6-hydroxy-(4E)-sphingenine-containing sphingolipids in only three (protected) or four (deprotected) consecutive steps, respectively, including a fluoresence-labeled derivative suitable for future biological studies.
