Protein tyrosine phosphatase 1B (PTP1B) has recently been identified as a potential target of Norathyriol. Unfortunately, Norathyriol is not a potent PTP1B inhibitor, which somewhat hinders its further application. Based on the fact that no study on the relationship of chemical structure and PTP1B inhibitory activity of Norathyriol has been reported so far, we attempted to perform structural optimization so as to improve the potency for PTP1B. Via structure-based drug design (SBDD), a rational strategy based on the binding mode of Norathyriol to PTP1B, we designed 26 derivatives with substitutions at the four phenolic hydroxyl groups of Norathyriol. By chemical synthesis and in vitro bioassay, we identified seven PTP1B inhibitors that were more potent than Norathyriol, of which XWJ24 showed the highest potency (IC50: 0.6 muM). We also found out that XWJ24 was a competitive inhibitor and showed the 4.5-fold selectivity over its close homolog, TC-PTP. Through molecular docking of XWJ24 against PTP1B, we highlighted the essential role of its hydrogen bond with Asp181 for PTP1B inhibition and identified a potential halogen bond with Asp48 that was not observed for Norathyriol. The current data indicate that our SBDD strategy is effective to discover potent PTP1B-targeted Norathyriol derivatives, and XWJ24 is a promising lead compound for further development.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 876-72-2 is helpful to your research. Reference of 876-72-2

Electrospun ultrathin fiber-based sensors are desirable because of their practicality and sensitivity. Ammonia-detection systems are in high demand in different areas, including the industrial and agricultural fields. However, current technologies rely on large and complex instruments that restrict their actual utilization. Herein, we report a flexible naked-eye ammonia sensor, the polylactic acid?cyanine (PLA-Cy) fibrous mat, which was fabricated by blending a carboxyl-functionalized cyanine dye (D1) into electospun PLA porous fibers. The sensing mat was shown to undergo a naked-eye-detectable color change from white to blue upon exposure to ammonia vapor. The mat showed high selectivity to ammonia gas with a detection limit of 3.3 ppm. Aggregated D1 was first encapsulated by PLA and was then ionized by NH3. These mechanisms were examined by photophysical studies and scanning electron microscopy. The aggregation?deaggregation process of D1 in the PLA-Cy fibrous mat led to the color change. This work provides a facile method for the naked-eye detection of ammonia and a novel strategy for the use of organic dyes in ammonia sensing.

G-quadruplex (G4) structures carry vital biological functions, and compounds that selectively target certain G4 structures have both therapeutic potential and value as research tools. Along this line, 2,2?-diindolylmethanes have been designed and synthesized in this work based on the condensation of 3,6- or 3,7-disubstituted indoles with aldehydes. The developed class of compounds efficiently stabilizes G4 structures without inducing conformational changes in such structures. Furthermore, the 2,2?-diindolylmethanes target certain G4 structures more efficiently than others and this G4 selectivity can be altered by chemical modifications of the compounds.

Auxin, indole-3-acetic acid (IAA), plays a crucial role for morphogenesis, development, growth, and tropisms in many plant species. Auxin biosynthesis is accomplished via specific pathways depending on several enzymes starting from amino acid, tryptophan. Auxin biosynthesis in maize is particularly active at the tip of coleoptile expressing abundant YUCC A (YUC) protein, which is essential for auxin biosynthesis. In vitro experiment demonstrated that precursor of auxin molecule; indole-3-acetaldehyde (IAAld) was generated by illumination of the mixture of tryptophan and flavin in nonenzymatic manner. In addition, we have detected immediate production of reactive oxygen species (ROS) in illuminated Arabidopsis root cells. In this perspective, we are proposing the non-enzymatic regulation of redox homeostasis and auxin biosynthesis throughout the plant body under variable environmental light conditions.

Gold-catalyzed oxidative couplings of two indoles and one alpha-cyano gold carbene to form bis(indolyl)methane derivatives are described. Two different indoles are compatible with these reactions to provide reasonable yields. A plausible mechanism is postulated to rationalize the experimental data including product distributions, D2O labeling, and the significant effects of gold catalysts and cyano groups.

The identification of a novel series of 7,8,9,10-tetrahydro-(7,10-ethano)- 1,2,4-triazolo[3,4-a]phthalazines as GABAAalpha5 inverse agonists, which have both binding and functional (efficacy) selectivity for the benzodiazepine binding site of alpha5- over alpha1-, alpha2-, and alpha3-containing GABAA receptor subtypes, is described. Binding selectivity was determined to a large part by the degree of planarity of the fused ring system whereas functional selectivity was dependent on the nature of the heterocycle at the 3-position of the triazolopyridazine ring. 3-Furan and 5-methylisoxazole were shown to be optimal for GABAAalpha5 functional selectvity. 3-(5-Methylisoxazol-3-yl)-6-(2-pyridyl)methyloxy-1,2,4- triazolo[3,4-a]phthalazine (43) was identified as a full inverse agonist at the GABAAalpha5 subtype with functional selectivity over the other GABAA receptor subtypes and good oral bioavailability.

The palladium-catalyzed synthesis of dihydroisobenzofurans has been performed by sequential Sonogashira cross-coupling/cyclization reactions between terminal alkynes and 2-(hydroxymethyl)bromoand chlorobenzenes in methanol as solvent at 130 C under microwave irradiation. A 4,4′-dichlorobenzophenone oxime-derived chloro-bridged palladacycle is an efficient pre-catalyst to perform this tandem process using 2-dicyclohexylphosphanyl-2′,4′,6′-triisopropylbiphenyl (Xphos) as ancillary ligand and potassium hydroxide as base in the absence of a copper cocatalyst. Under these conditions, functionalized 2-bromo- and 2-chlorobenzaldehydes are also suitable partners in the domino process affording phthalans in good yields. All the reactions can be performed under air and employing reagentgrade chemicals under low loading conditions (1 mol% Pd).
