Transporter-related nutrient sensors, called transceptors, mediate nutrient activation of signaling pathways through the plasma membrane. The mechanism of action of transporting and nontransporting transceptors is unknown. We have screened 319 amino acid analogs to identify compounds that act on Gap1, a transporting amino acid transceptor in yeast that triggers activation of the protein kinase A pathway. We identified competitive and noncompetitive inhibitors of transport, either with or without agonist action for signaling, including nontransported agonists. Using substituted cysteine accessibility method (SCAM) analysis, we identified Ser388 and Val389 as being exposed into the amino acid binding site, and we show that agonist action for signaling uses the same binding site as used for transport. Our results provide the first insight, to our knowledge, into the mechanism of action of transceptors. They indicate that signaling requires a ligand-induced specific conformational change that may be part of but does not require the complete transport cycle.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Seven platinum(II) complexes formulated as Pt(bph)L, where bph is the 2,2?-biphenyl dianion and L = 4-methyl-1,10-phenanthroline (4-Mephen), 5-methyl-1,10-phenanthroline (5-Mephen), 5-chloro-1,10-phenanthroline (5-Clphen), 5,6-dimethyl-1,10-phenanthroline (5,6-Me2phen), 4,7-dimethyl-1,10-phenanthroline (4,7-Me2phen), 4,7-diphenyl-1,10- phenanthroline (4,7-Ph2phen) and 3,4,7,8-tetramethyl-1,10- phenanthroline (3,4,7,8-Me4phen) are reported. Protons attached to the phen ligand resonate downfield from those attached to the bph ligand and two proton signals are split by interaction with 195Pt. Pt(bph)(3,4,7,8-Me4phen), Pt(bph)(4,7-Me2phen), Pt(bph)(5,6-Me2phen), Pt(bph)(4,7-Ph2phen) and Pt(bph)(5-Mephen) crystallize in the space groups Pna21, P2 1/n, P21/c, P – 1 and Pca21, respectively. The structures of the complexes deviate from true planarity and divide themselves into two groups where the bph and phen ligands cross in an X configuration or bow out in a butterfly (B) configuration. Circular dichroism revealed two different spectra with respect to the X and B configurations.

Three series of novel indazole-pyrimidine based compounds were designed, synthesized and biologically evaluated as VEGFR-2 kinase inhibitors. The most active compound 6i (IC50 = 24.5 nM) was further evaluated against a HUVEC cell line showing an IC50 of 1.37 muM. Moreover, it showed an indirect anti-angiogenic effect through the suppression of secretion of VEGF and TGF-b1 from prostate cancer cells. Five compounds were selected by the NCI for evaluation of their in vitro anticancer activity against the full NCI panel of cell lines at 10 muM. Compounds 6e and 6f were further selected for 5-dose testing. Compound 6e exerted nanomolar GI50 values against several cell lines: CCRF-CEM (901 nM), MOLT-4 (525 nM) and CAKI-1 (992 nM) and one digit micromolar activity against the rest of the cell lines ranging from 1.05 muM to 2.41 muM. Compound 6f showed one digit micromolar activity against the whole panel of cell lines ranging from 1.55 muM to 7.4 muM. A molecular docking study was employed to investigate the predicted binding mode of the target compounds with VEGFR-2, using Autodock software. Furthermore, MD simulation was implemented for compounds 6i and 10c for further validation and rationalization of their binding mode.

Application of 18531-99-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.18531-99-2, Name is (S)-[1,1′-Binaphthalene]-2,2′-diol, molecular formula is C20H14O2. In a article，once mentioned of 18531-99-2

Five sets of oxido-vanadium(V) complexes, which include both cages and open structures, were prepared and tested in the catalytic oxidation of sulfides. It was found that the hemicryptophane complexes, which are simultaneously comprised of cyclotriveratrylene (CTV), binaphthol and oxido-vanadium(V) moieties, are the most efficient supramolecular catalysts. The specific shape of the confined hydrophobic space above the metal center leads to a strong improvement in the yield, selectivity and rate of the reaction, compared to the other catalysts investigated herein. A remarkable turnover number (TON) of 10 000 was obtained, which can be attributed to both the high reactivity and stability of the catalyst. Similarly to enzymes, the kinetic analysis shows that the mechanism of oxidation with the supramolecular catalysts obeys the Michaelis-Menten model, in which initial rate saturation occurs upon an increase in substrate concentration. This enzyme-like behavior is also supported by the competitive inhibition and substrate size-selectivity observed, which underline the crucial role played by the cavity.

A tetrakis(dialkylamino)phosphonium cation was evaluated as a functional group for alkaline anion exchange membranes (AAEMs). The base stability of [P(N(Me)Cy)4]+ was directly compared to that of [BnNMe3]+ in 1 M NaOD/CD3OD. The high base stability of [P(N(Me)Cy)4]+ relative to [BnNMe 3]+ inspired the preparation of AAEM materials composed of phosphonium units attached to polyethylene. The AAEMs (hydroxide conductivity of 22 ± 1 mS cm-1 at 22 C) were prepared using ring-opening metathesis polymerization, and their stabilities were evaluated in 15 M KOH at 22 C and in 1 M KOH at 80 C.

A series of N-formamides derived from pipecolinic acid have been synthesized and tested as Lewis base catalysts for the enantioselective reduction of N-aryl imines by trichlorosilane. Through the investigation of the structure-efficacy relationship between the side amide group and catalytic performance, several highly effective catalysts were discovered. In particular, arylamido-type catalyst 5i and non-arylamido-type catalyst 6c exhibited high reactivity and enantioselectivity, furnishing the reduction of a wide variety of N-aryl imines with high isolated yields (up to 98%) and ee values (up to 96%) under mild conditions. Moreover, these two catalysts complement each other in terms of their tolerances to nonaromatic ketimines and non-methyl ketimines. The Royal Society of Chemistry 2013.
