Studies toward asymmetric synthesis of leiodelide A

An enantioselective route for oxazoline 4, a key fragment toward the asymmetric synthesis of leiodelide A, is described. We synthesized northern subunit 6 through a Julia-Lythgoe olefination and subsequent Sharpless asymmetric dihydroxylation. Moreover, a highly diastereoselective method using well-established Evans’ asymmetric aldol condensation was developed for preparation of southern fragment 5. The additional feature of this synthetic route is the formation of oxazoline 4 through DAST-promoted cyclization of the amidation product from subunits 5 and 6.

Discovery of cytotoxic and pro-apoptotic compounds against leukemia cells: Tert-butyl-4-[(3-nitrophenoxy) methyl]-2,2-dimethyloxazolidine-3-carboxylate

Aims: We evaluated biological activity in leukemia cells lines of R and S enantiomers of tert-butyl 4-[(3-nitrophenoxy)-methyl]-2,2-dimethyloxazolidine-3- carboxylate (BNDC). Main methods: Cytotoxic activity was assessed by MTT assay. Flow cytometry assays were used to determined DNA fragmentation (Propidium Iodide-PI staining) and phosphatidylserine exposure (Annexin-V and PI staining). DNA condensation was evaluated by fluorescence microscopy using double-staining in leukemia cells (Hoechst and PI). Caspase activities were measured using Z-VAD-FMK, a non-selective caspase inhibitor, by flow cytometry and Z-DEVD-AMC, a selective caspase-3 substrate, by fluorescence spectrometry. Key findings: Both enantiomers displayed cytotoxic activity against leukemia cell lines (HL60, HL60.Bcl-2, HL60.Bcl-XL and Jurkat) with low toxicity against human peripheral blood mononuclear cell – PBMC based on IC50 values. In HL60 cell lines, compounds induce exposure of phosphatidylserine and DNA fragmentation, which could be blocked by pretreatment of cells with Z-VAD-FMK. Confirming this observation, both enantiomers induced caspase-3 activation. Additional analysis revealed an increased percentage of apoptotic cells (defined as those with fragmented nuclei and condensed chromatin) after treatment with compounds. Significance: Taken together, the results indicate that BNDC compounds exhibited cytotoxic and pro-apoptotic activities and have a potential for developing a new class of anticancer drugs.

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.

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.

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.

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.

Asymmetric synthesis of beta-amino acids by addition of chiral enolates to nitrones via N-acyloxyiminium ions

N-Acyloxyiminium ions, generated by the reaction of nitrones with acyl halides, are highly reactive species and undergo facile reaction with a wide range of nucleophiles, such as ketene silyl acetals, titanium(IV) and boron enolates, hydrido- and allyltin(IV) reagents, and alkynyltitanium(IV) reagents, to give alpha-substituted amine derivatives. Optically active beta-amino acids can be prepared by the reaction of N-acyloxyiminium ions with both boron and titanium(IV) enolates bearing chiral auxiliaries. Reversal of diastereoselectivity was observed by the reactions of the boron and titanium(IV) enolates. Using these reactions, all of the four stereoisomers of alpha-methyl-beta-phenylalanines, for example, can be prepared highly diastereoselectively. Cyclic N-acyloxyiminium ions are useful for the asymmetric synthesis of pyrrolidine and piperidine alkaloids; (5R,8R,8aS)-5-cyano-8-methylindolizidine, which is a common key intermediate for synthesis of 5-substituted 8-methylindolizidines, was prepared selectively.

Potential tuberculostatic agent: Micelle-forming pyrazinamide prodrug

Pyrazinamide was condensed with the poly(ethylene glycol)-poly(aspartic acid) copolymer (PEG-PASP), a micelle-forming derivative was obtained that was characterized in terms of its critical micelle concentration (CMC) and micelle diameter. The CMC was found by observing the solubility of Sudan III in Poly(ethylene glycol)-poly(pyrazinamidomethyl aspartate) copolymer (PEG-PASP-PZA) solutions. The mean diameter of PEG-PASP-PZA micelles, obtained by analyzing the dynamic light-scattering data, was 78.2 nm. The PEG-PASP-PZA derivative, when assayed for anti-Mycobacterium activity, exhibited stronger activity than the simple drug.

Electrogenerated N-heterocyclic carbene: N-acylation of chiral oxazolidin-2-ones in ionic liquids

An electrochemical procedure for the N-acylation of chiral oxazolidin-2-ones, in the absence of volatile molecular organic solvents, has been set up via electrolyses of ionic liquid [bmim]BF4 containing oxazolidin-2-ones followed by addition of saturated or unsaturated anhydrides. N-acyloxazolidin-2-ones were isolated in good to elevated yields. The electrochemically induced N-acylation of chiral oxazolidin-2-ones occurs with total retention of the absolute configuration of all the chiral atoms. The electrogenerated carbene (1-butyl-3-methyl-1H-imidazol-2-ylidene) has been indicated as the base involved in the deprotonation of chiral oxazolidin-2-ones.
