Chinese quince (Chaenomeles sinensis) is used in food and pharmaceutical products, but it is seldom eaten as a raw fruit due to its astringent, woody flesh. The structural characterization of lignin fractions from Chinese quince was very important to investigate the structure-activity relationships of lignin. In this investigation, to characterize the structure of lignin in Chinese quince fruits, the milled wood lignin sample was isolated from the fruits (FMWL) and the chemical structure of FMWL was investigated by sugar analysis, FT-IR, GPC, pyrolysis-GC/MS analysis, UV spectra analysis, thermogravimetric analysis (TGA), and advanced NMR spectroscopic techniques. In addition, the lignin fraction from the stalk of Chinese quince (SMWL) was also prepared for comparison to obtained more information of lignin structure in the fruits. The results showed that the two lignin fractions isolated from fruit and stalk of Chinese quince exhibited different structural features. The two MWL samples were mainly composed of-O-4 ether bonds,-5 and-0 carbon-carbon linkages in the lignin structural units. Compared to the SMWL, the FMWL fraction had the higher S/G ratio and more carbohydrates linkages. The predominant carbohydrates associated with FMWL and SMWL fractions were glucans-type hemicelluloses and xylan-type hemicelluloses, respectively. Understanding the structure of lignin could give insight into the properties of the lignin and enable the food processing industry to separate lignin more efficiently.

The synthesis and spectral properties (IR, MS, NMR) of a substituted 5-(2,3-dihydro-7-benzofuryl)pyrazolo[4,3-d]pyrimidin-7-one (2), an analog of Viagra (1), are described. The generally applicable route involves interaction of 2,3-dihydro-7-benzofuranoyl chloride (3) with 4-amino-1-methyl-3-propyl-5-pyrazolecarboxamide (4), and the resulting bis-amide (5) is cyclized to the corresponding substituted pyrazolo[4,3-d]pyrimidin-7-one (6). Chlorosulfonylation of 6, followed by treatment with 1-methylpiperazine, furnished the title compound 2 (named Biagra). Preliminary experiments “associated with the erectile process” on rats lend evidence of greater potency of Biagra (2) as compared to Viagra (1).

Commercially available FeCl3·6H2O with conformationally rigid diamine ligand is a highly effective catalyst for N-arylation of pyrazoles using aryl and heteroaryl iodides. It is notable to show that this complex is tolerable under aqueous medium and particularly the whole reaction utilizes water as the sole solvent without any additional organic co-solvents and surfactants. Attempted study using other nitrogen nucleophiles is described. This newly developed system provides an alternative protocol to Cu- and Pd-catalyzed N-arylation reactions.

N-Myristoyltransferase (NMT) is an attractive antiprotozoan drug target. A lead-hopping approach was utilized in the design and synthesis of novel benzo[b]thiophene-containing inhibitors of Plasmodium falciparum (Pf) and Plasmodium vivax (Pv) NMT. These inhibitors are selective against Homo sapiens NMT1 (HsNMT), have excellent ligand efficiency (LE), and display antiparasitic activity in vitro. The binding mode of this series was determined by crystallography and shows a novel binding mode for the benzothiophene ring.

We report a new sensor, 1, for sequentially detecting Zn2+ and CN- based on fluorescence. Sensor 1 was prepared through the reaction of 3-aminobenzofuran-2-carboxamide with 4-diethylaminosalicylaldehyde. Sensor 1 showed a selective “off-on” fluorescent response toward Zn2+, distinguishing Zn2+ from Cd2+. The limit of 1 (0.35 muM) for monitoring Zn2+ is lower than the World Health Organization (WHO) guideline (76 muM) for water available for drinking. Importantly, sensor 1 could sense Zn2+ in living cells and aqueous media. In addition, the resulting 1-Zn2+ complex functioned as an efficient “on-off” sensor for CN-. The mechanisms of 1 for detecting Zn2+ and CN- were explained by spectroscopic, spectrometric, and theoretical studies.

Most drugs are developed through iterative rounds of chemical synthesis and biochemical testing to optimize the affinity of a particular compound for a protein target of therapeutic interest. This process is challenging because candidate molecules must be selected from a chemical space of more than 1060 drug-like possibilities 1, and a single reaction used to synthesize each molecule has more than 107 plausible permutations of catalysts, ligands, additives and other parameters 2 . The merger of a method for high-throughput chemical synthesis with a biochemical assay would facilitate the exploration of this enormous search space and streamline the hunt for new drugs and chemical probes. Miniaturized high-throughput chemical synthesis 3-7 has enabled rapid evaluation of reaction space, but so far the merger of such syntheses with bioassays has been achieved with only low-density reaction arrays, which analyse only a handful of analogues prepared under a single reaction condition 8-13 . High-density chemical synthesis approaches that have been coupled to bioassays, including on-bead 14, on-surface 15, on-DNA 16 and mass-encoding technologies 17, greatly reduce material requirements, but they require the covalent linkage of substrates to a potentially reactive support, must be performed under high dilution and must operate in a mixture format. These reaction attributes limit the application of transition-metal catalysts, which are easily poisoned by the many functional groups present in a complex mixture, and of transformations for which the kinetics require a high concentration of reactant. Here we couple high-throughput nanomole-scale synthesis with a label-free affinity-selection mass spectrometry bioassay. Each reaction is performed at a 0.1-molar concentration in a discrete well to enable transition-metal catalysis while consuming less than 0.05 milligrams of substrate per reaction. The affinity-selection mass spectrometry bioassay is then used to rank the affinity of the reaction products to target proteins, removing the need for time-intensive reaction purification. This method enables the primary synthesis and testing steps that are critical to the invention of protein inhibitors to be performed rapidly and with minimal consumption of starting materials.

A liquid crystal (LC) based method is described for the sensitive determination of the activity of urease and of heavy metal ions which acts as inhibitors. Stimulus-responsive surfactant-encapsulated phosphotungstate clusters (SECs) were fabricated and deposited onto octadecyltrichlorosilane-coated glass. A copper TEM grid filled with LCs was placed on the substrate to construct the LC optical cell. Upon addition of water to the LC interface, the optical appearance of LCs on the glass undergoes a bright-to-dark shift due to an orientational transition of the LCs from a planar to a homeotropic state. However, the LCs display a bright appearance if they are pretreated with an aqueous solution containing urea and urease. This is caused by the disassemby of the SECs from the glass surface due to an increase of the pH value that is induced by the enzymatic hydrolysis of urea by urease. The method is highly sensitive and can detect urease activities as low as 0.03 mU/mL. It can also be applied to the determination of heavy metal ions which exert an inhibitory effect on the activity of urease. For example, Cu(II) can be quantified via urease inhibition in 1 nM concentration.
