New 4-amino-N-alkylphthalimides as fluorescence probes for beta-cyclodextrin inclusion complexes and hydrophobic microdomains of amphiphilic systems

The synthesis and photophysical behaviour of a series of 4-amino-N-alkylphthalimides have been described. The complexation between beta-cyclodextrin and the different phthalimides has been studied by steady-state fluorescence. The association constant K depends strongly on the hydrophobicity of the alkyl substituent, and the K values vary between 115 M-1 and 19,000 M-1. The studied compounds have been used as fluorescent probes to determine the first and second association constants of surfactants with beta-cyclodextrin from competitive binding data. The results are compared with those given by other authors, and limitations of the method are discussed. 4-Amino-N-tert-butylphthalimide is also used as a sensor for following micellar aggregation process of surfactants and autoassociation of hydrophobically modified polymers. Values of critical micellar concentration (cmc) and critical aggregation concentration (cac) are determined, and comparison is made with pyrene.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, HPLC of Formula: C13H30BrN, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 2082-84-0

Enantioselective synthesis and stereoselective ring opening of N-acylaziridines

Kinetic resolution of N-acylaziridines by nucleophilic ring opening was achieved with (R)-BINOL as the chiral modifier under boron-catalyzed conditions (see scheme; Ar=3,5-dinitrophenyl). The consumed enantiomer of aziridine can be further converted to an enantioenriched 1,2-chloroamide with recovery of (R)-BINOL. Copyright

Novel vanadium complexes with rigid carboxylate ligands: Synthesis, structure and catalytic bromine dynamics of phenol red

In this work, by selecting appropriate ligands, novel vanadium complexes [VIVO(2,6-pdc)(Phen)]¡¤3H2O (1) and [(VIVO)(C5H5N2O2)2H2O]¡¤2H2O (2) (2,6-pdc = 2,6-pyridinedicarboxylic acid, Phen = 1,10-Phenanthroline monohydrate) were synthesized by the reaction of V2(SO4)3, 2,6-pdc and Phen (for 1), VO(acac)2 and C5H6N2O2 (for 2) via solution or hydrothermal methods. Two complexes were characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TG), UV-vis spectroscopy and the single crystal X-ray diffraction. Structural analyses reveal that the vanadium atom has distorted octahedral geometry in 1 and 2 with donor sets of N3O3 and N2O4, respectively. The complexes which catalyze the oxidation of the organic substrate phenol red in the presence of H2O2 and bromide exhibited catalytic bromination activity, and the reaction system is considered as an effective model for hydrogen peroxide determination. The reaction rate constant (k) for complexes 1 and 2 can be calculated as 2.13 ¡Á 102 and 2.64 ¡Á 102 (mol/L)?2s?1, respectively.

Ancillary ligand control of the regiochemistry of coupling of 3,3-dimethyl-1-butyne at titanium metal centers

The ambient-temperature sodium amalgam (2 Na per Ti) reduction of hydrocarbon solutions of [Cp(ArO)TiCl2] (ArO = 2,3,5,6-tetraphenylphenoxide) (1) in the presence of 3,3-dimethyl-1-butyne yields the 2,5-di(tert-butyl)titanacyclopentadiene compound [Cp(ArO)Ti(C4H2Bu2t-2,5)] (2). An X-ray diffraction study of 2 confirms the regiochemistry and shows carbon – carbon distances of 1.343(3) and 1.492(3) A for the double and single bonds, respectively. In contrast the analogous reaction of either [Cp2TiCl2] or [(ArO)2TiCl2] in the presence of 3,3-dimethyl-1-butyne yields the corresponding 2,4-di(tert-butyl)titanacyclopentadiene compounds. When 2 is heated at 100 C for a few days in C6D6 solution, isomerization to the more stable 2,4-di(tertbutyl) regioisomer 3 is observed by NMR. An attempt is made to rationalize the regiochemistry of the kinetically formed titanacyclopentadiene in terms of steric factors within the intermediate bis(alkyne) complex.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1271-19-8 is helpful to your research. name: Titanocenedichloride

Amine-boranes: Effective reducing agents for the deracemisation of DL-amino acids using L-amino acid oxidase from Proteus myxofaciens

The deracemisation of DL-alpha-amino acids using L-amino acid oxidase from Proteus myxofaciens and amine-boranes as chemical reducing agents has been investigated. Amine-boranes were found to be of particular interest in terms of reactivity and chemoselectivity compared to sodium borohydride and cyanoborohydride. Starting from the racemate, a range of D-amino acids were obtained in yields of up to 90% and e.e. >99%.

Design, synthesis, and evaluation of novel Akt1 inhibitors based on an indole scaffold

A new series of potential Akt1 inhibitors with indole scaffold were designed and synthesized. The antiproliferative activity against PC-3 cell line and enzyme inhibitory activity against Akt1 were evaluated. Among them, some compounds showed much more potent antiproliferative activity and stronger Akt1 inhibitory activity compared to the positive control of GSK690693. In particular, compound 19b exhibited the most potent inhibitory activity against Akt1 with inhibition rate of 70.3% at a concentration of 10?nm. Furthermore, compound 19b could dose dependently reduce the phosphorylation of the downstream GSK3beta protein in the PC-3 cell line and displayed fivefold higher antiproliferative activity against PC-3 cell line with IC50 value of 3.1?¡À?0.1?mum than positive control (15.5?¡À?0.4?mum). Herein, compound 19b may serve as a promising lead for further optimization and development of novel Akt1 inhibitors based on an indole scaffold.
