Potentiality and Synthesis of O- and N-Heterocycles: Pd-Catalyzed Cyclocarbonylative Sonogashira Coupling as a Valuable Route to Phthalans, Isochromans, and Isoindolines

Oxygen and nitrogen heterocycle systems are found in a vast number of natural substrates and biologically active molecules. In particular, phthalan, isochroman, and isoindoline scaffolds are present in many classes of products such as anti-mycotics, antibiotics, antioxidants, pigments, and fluorophores. Therefore several procedure dedicated to the building of such heterocycles have been developed. In this review a detailed analysis of literature data relating to these scaffolds is described. Particular attention has been devoted to their biological and chemical potentiality, and an in-depth investigation into the most important synthetic methods is reported. Cyclo-carbonylative Sonogashira coupling of suitable alcohols and amides has been carefully considered, because it represents a valuable and atom-economic route for the construction of alkylidenephthalans, -isochromans, and -isoindolines.

Synthesis of Mepivacaine and Its Analogues by a Continuous-Flow Tandem Hydrogenation/Reductive Amination Strategy

Herein we report a convenient, fast, and high-yielding method for the generation of the racemic amide anaesthetics mepivacaine, ropivacaine, and bupivacaine. Coupling of -picolinic acid and 2,6-xylidine under sealed-vessel microwave conditions generates the intermediate amide after a reaction time of only 5 min at 150 degrees C. Subsequent reaction in a continuous-flow high-pressure hydrogenator (H-Cube Pro(TM)) in the presence of the respective aldehyde directly converts the intermediate to the final amide anaesthetics in a continuous, integrated, multi-step ring-hydrogenation/reductive amination protocol. Merits and limitations of the protocol are discussed.

Systemic Immunotherapy with Micellar Resiquimod-Polymer Conjugates Triggers a Robust Antitumor Response in a Breast Cancer Model

Resiquimod is an immunopotent toll-like receptor 7/8 agonist with antitumor activity. Despite being potent against skin cancers, it is poorly tolerated systemically due to toxicity. Integrating resiquimod into nanoparticles presents an avenue to circumvent the toxicity problem. Herein, the preparation of degradable nanoparticles with covalently bound resiquimod and their systemic application in cancer immunotherapy is reported. Dispersion in water of amphiphilic constructs integrating resiquimod covalently bound via degradable amide or ester linkages yields immune-activating nanoparticles. The degradable agonist-nanoparticle bonds allow the release of resiquimod from the carrier nanoparticles. In vitro assays with antigen presenting cells demonstrate that the nanoparticles retain the immunostimulatory activity of resiquimod. Systemic administration of the nanoparticles and checkpoint blockade (aPD-1) to a breast cancer mouse model with multiple established tumors triggers antitumor activity evidenced by suppressed tumor growth and enhanced CD8(+) T-cell infiltration. Nanoparticles with ester links, which hydrolyze more readily, yield a stronger immune response with 75% of tumors eliminated when combined with aPD-1. The reduced tumor growth and the presence of activated CD8(+) T-cells across multiple tumors suggest the potential for treating metastatic cancer.

Clarifying the dehydrogenation pathway of catalysed Li-4(NH2)(3)BH4-LiH composites

The effect of different metal oxides (Co3O4 and NiO) on the dehydrogenation reaction pathways of the Li-4(NH2)(3)BH4-LiH composite was investigated. The additives were reduced to metallic species i.e. Co and Ni which act as catalysts by breaking the B-H bonds in the Li-B-N-H compounds. The onset decomposition temperature was lowered by 32 degrees C for the Ni-catalysed sample, which released 8.8 wt% hydrogen below 275 degrees C. It was demonstrated that the decomposition of the doped composite followed a mechanism via LiNH2 and Li3BN2 formation as the end product with a strong reduction of NH3 emission. The sample could be partially re-hydrogenated (similar to 1.5 wt%) due to lithium imide/amide transformation. To understand the role of LiH, Li-4(NH2)(3)BH4-LiH-NiO and Li-4(NH2)(3)BH4-NiO composites were compared. The absence of LiH as a reactant forced the system to follow another path, which involved the formation of an intermediate phase of composition Li3BN2H2 at the early stages of dehydrogenation and the end products LiNH2 and monoclinic Li3BN2. We provided evidence for the interaction between NiO and LiNH2 during heating and proposed that the presence of Li facilitates a NHx-rich environment and the Ni catalyst mediates the electron transfer to promote NHx coupling.

Synthesis Route to Pyrrolones from -Cyano ,-Unsaturated Ketones and -Isocyano Esters by Oxidative Dearomatization of 2-Aminofuran Intermediates

An efficient method for the catalyst/promoter-free synthesis of tetrasubstituted furan derivatives proceeding through the [4+1] cycloaddition of isocyanoacetates with electron-deficient olefins was developed. The products were obtained in good to excellent yields without any column chromatography. Oxidative dearomatization of these furans was achieved only in the presence of oxygen, which led to pyrrolones in high yields.

Iron oxide nanospheres and nanocubes modified with carboxyphenyl porphyrin and their magnetic, optical properties and photocatalytic activities in room temperature amide synthesis

Superparamagnetic iron oxide nanoparticles of different shapes and sizes combined with 5-(4-carboxyphenyl)-10,15,20-triphenylporphinatozinc(II) (SPION-ZnCTPP) were prepared and investigated as a novel and potent magnetically responsive photocatalyst. Nanospheres and nanocubes of SPIONs in the sizes of 10 and 20 nm were synthesized using thermal decomposition method before coating with ZnCTPP. Morphologies of SPIONs were observed using a transmission electron microscope (TEM). Herein the attachment of ZnCTPP on particles was studied using various techniques including infrared spectroscopy (IR) and UV-visible spectroscopy and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Moreover, the obtained particles showed superparamagnetic character with saturation magnetization in a range of 10 to 76 emu/g, depending on the size and shape of the SPIONs. The SPION-ZnCTPP showed high photocatalytic activity (52% yield) for amide synthesis between potassium ethanethioate and 4-methoxyaniline under irradiation with a 19 W LED lamp, and this heterogeneous catalyst could be well separated from a solution under the induction of an external magnetic field.

Both modular and single-domain Type I polyketide synthases are expressed in the brevetoxin-producing dinoflagellate, Karenia brevis (Dinophyceae)

Dinoflagellates are prolific producers of polyketide compounds, many of which are potent toxins with adverse impacts on human and marine animal health. To identify polyketide synthase (PKS) genes in the brevetoxin-producing dinoflagellate, Karenia brevis, we assembled a transcriptome from 595 million Illumina reads, sampled under different growth conditions. The assembly included 125,687 transcripts greater than 300 nt in length, with over half having >100x coverage. We found 121 transcripts encoding Type I ketosynthase (KS) domains, of which 99 encoded single KS domains, while 22 contained multiple KS domains arranged in 1-3 protein modules. Phylogenetic analysis placed all single domain and a majority of multidomain KSs within a monophyletic clade of protist PKSs. In contrast with the highly amplified single-domain KSs, only eight single-domain ketoreductase transcripts were found in the assembly, suggesting that they are more evolutionarily conserved. The multidomain PKSs were dominated by trans-acyltransferase architectures, which were recently shown to be prevalent in other algal protists. Karenia brevis also expressed several hybrid nonribosomal peptide synthetase (NRPS)/PKS sequences, including a burA-like sequence previously reported in a wide variety of dinoflagellates. This contrasts with a similarly deep transcriptome of Gambierdiscus polynesiensis, which lacked NRPS/PKS other than the burA-like transcript, and may reflect the presence of amide-containing polyketides in K.brevis and their absence from G.polynesiensis. In concert with other recent transcriptome analyses, this study provides evidence for both single domain and multidomain PKSs in the synthesis of polyketide compounds in dinoflagellates.

A new route to alpha,omega-diamines from hydrogenation of dicarboxylic acids and their derivatives in the presence of amines

A new and selective route for the synthesis of polymer precursors, primary diamines or N-substituted diamines, from dicarboxylic acids, diesters, diamides and diols using a Ru/triphos catalyst is reported. Excellent conversions and yields are obtained under optimised reaction conditions. The reactions worked very well using 1,4-dioxane as solvent, but the greener solvent, 2-methyl tetrahydrofuran, also gave very similar results. This method provides a potential route to converting waste biomass to value added materials. The reaction is proposed to go through both amide and aldehyde pathways.

A Heterometallic MOF for Highly Selective Al(3+)Ion Detection and Protective Effect Against Periodontitis by ReducingP. gingivalisCFU and Inflammatory Cytokines Levels

By employment of an amide-functionalized tetracarboxylic ligand 5,5 ‘-(carbonylbis(azanediyl))-diisophthalic acid (H(4)cbab), a new polyhedral metal-organic framework (MOF) with the chemical formula of {[InZn2(cbda)(2)(H2O)(2)](NMF)(3)}(n)(1, NMF = N-methylformamide) has been synthesized under the solvothermal reaction condition. The structural feature was studied via the single crystal X-ray diffraction along with ultimate analysis. This as-prepared MOF shows excellent luminescence performance which can be able to detect Al(3+)ions selectively. In aqueous solutions, the detection limitation for Al(3+)ion is 0.56 mu M, which is significantly below the highest standard of 7.41 mu M for Al(3+)ion in drinking water that is defined by the World Health Organization (WHO). The protective effect of compound against periodontitis was further explored. The viable cell counts (CFU) number was counted to evaluate the inhibitory effect of compound on bacterial growth. The enzyme linked immunosorbent assay (ELISA) was carried on in order to measure accurately the proportion of inflammatory cytokines in gingival fluid around the implant. The potential binding modes of the synthesized compounds as well as the targeted protein was explored by calculating docking with high accuracy as well as pose scoring process.

Amide-functionalized heterometallic helicate cages as highly efficient catalysts for CO2 conversion under mild conditions

Mimicking nature seems to be one of the smartest strategies to design novel catalysts for CO2 conversion under mild conditions. Herein, we report a facile and efficient method to construct two amide-functionalized heterometallic helicate cages as enzyme mimic catalysts for the synthesis of cyclic carbonates. These helicate cages show high thermal stability and exceptionally high catalytic activity and size-dependent selectivity toward small epoxides in catalytic CO2 cycloaddition to obtain cyclic carbonates even under ambient conditions. The construction of this novel functionalized cage provides an efficient approach for realizing CO2 conversion under mild conditions.
