In order to develop a novel herbicide containing the beta-triketone motif, a series of 4-hydroxyl-3-(2-phenoxyacetyl)-pyran-2-one derivatives were designed and synthesized. The bioassay results showed that compound II15 had good pre-emergent herbicidal activity even at a dosage of 187.5 g ha(-1). Moreover, compound II15 showed a broader spectrum of weed control when compared with a commercial herbicide 2,4-dichlorophenoxyacetic acid (2,4-D), and displayed good crop safety to Triticum aestivum L. and Zea mays Linn. when applied at 375 g ha(-1) under pre-emergence conditions, which indicated its great potential as a herbicide. More importantly, studying the molecular mode of action of compound II15 revealed that the novel triketone structure is a proherbicide of its corresponding phenoxyacetic acid auxin herbicide, which has a herbicidal mechanism similar to that of 2,4-D. The present work indicates that the 4-hydroxyl-3-(2-phenoxyacetyl)-pyran-2-one motif may be a potential lead structure for further development of novel auxin-type herbicides.

A new set of compounds which are intra-molecularly hydrogen bonded have been synthesized and analyzed with special reference to Resonance Assisted Hydrogen Bonding (RAHB). The structure and stereochemistry of the synthesized compounds (1-10), were established on the basis of their analytical and spectral data (IR, H-1, C-13 NMR, HOMOCOSY, NOESY, HSQC and HMBC). The structure in the solid state for 5, 9 and 10 is clearly established by single crystal X-ray diffraction analysis. Spectral and single crystal Xray structural study confirms the flattened boat conformation of the heterocyclic ring which is analyzed with the help of dihedral angles and the mean plane deviations. Hirshfeld surface analysis is carried out and the packing interactions are discussed. The prevalent intramolecular hydrogen bonding is well proved by XRD analysis and the type of hydrogen bonding is classified as S(6), and the resonance assistance for the hydrogen bonding is also quantified and discussed explicitly. Antimicrobial studies were performed for the synthesized compounds against some Gram positive and Gram negative bacterial strains and some fungal strains and the results are summarized.

Leishmaniasis is a neglected parasitic disease, and current treatment includes limitations of toxicity, variable efficacy, high costs and inconvenient doses and treatment schedules. Therefore, new leishmanicidal drugs are still an unquestionable medical need. In this paper we described the design conception of a new framework, the carbamoyl-N-aryl-imine-urea, to obtain putative leishmanicidal drug-candidates. Compounds 9a-e and 10a-e were designed and synthesized and their leishmanicidal activity was studied in comparison to pentamidine, miltefosine and meglumine antimoniate. The conformational profile of the new carbamoyl-N-aryl-imine-urea framework was investigated by X-ray diffraction studies, using compound 9a as a model. The plasma stability of this putative peptide mimetic subunit was studied for compound 10e (LASSBio-1736). Among the congeneric series, LASSBio-1736 was identified as a new antileishmanial drug-candidate, displaying plasma stability, cytotoxicity against amastigote forms of L. amazonensis and L. braziliensis, and leishmanicidal activity in a cutaneous leishmaniasis murine model, without preliminary evidence of hepatic or renal toxicity.

One of the fundamental and highly valuable transformations in organic chemistry is the nucleophilic substitution of alcohols. Traditionally, these reactions require strategies that employ stoichiometric hazardous reagents and are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an S(N)2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C bonds. Furthermore, we also demonstrate that this method can be used for the preparation and late-stage functionalization of pharmaceuticals, as highlighted by the syntheses of thiocarlide, butoxycaine, and pramoxine.

A highly enantioselective kinetic resolution of sterically hindered benzylamines has been achieved for the first time through transition-metal-catalyzed oxidative carbonylation, in which the new KR strategy offered a new approach to afford chiral isoindolinones (er up to 97 : 3) and the origin of chemoselectivity and stereoselectivity was confirmed by density functional theory (DFT) calculations.

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatographic fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behaviour of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatographic fingerprints, for diverse experimental conditions in isocratic and gradient elution. Another interesting application is the prediction of molecular properties, such as log P-o/w from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Roses to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of camomile extracts analysed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.

In this approach, low-dimensional silver oxide decorated carbon black nanocomposites (Ag2O/CB NCs) were synthesized by a facile wet-chemical process at low temperature. The prepared composites were characterized by Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV/vis), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and X-ray powder diffraction (XRD). A thin layer of Ag2O/CB NC was deposited on the glassy carbon electrode (GCE) with a conducting binder to produce the working electrode of a chemical sensor. The fabricated chemical sensor was used for the successive in vitro detection of 3-methoxyphenol (3-MP) by an electrochemical method at a lower applied potential. The sensor response towards 3-MP is linear in a logarithmic scale over a large concentration range (0.09 nM to 9.0 mu M). The analytical parameters of the sensor, including good sensitivity (45.7278 mu A mu M-1 cm(-2)), low detection limit (LOD = 9.73 +/- 0.49 pM at a signal to noise ratio of 3), good reliability, good reproducibility, and long-term stability were examined. Therefore, the proposed chemical sensor based on Ag2O/CB NCs/binder/GCE may be a promising sensitive chemical sensor in reliable electrochemical approaches for the broad-scale detection of hazardous and carcinogenic chemicals in the health care and environmental sectors.
