Versatile (Pentamethylcyclopentadienyl)rhodium-2,2?-Bipyridine (Cp?Rh-bpy) Catalyst for Transfer Hydrogenation of N-Heterocycles in Water

An investigation employing the catalytic system consisting of (pentamethylcyclopentadienyl)rhodium dichloride dimer [Cp?RhCl2]2 and 2,2?-bipyridine (bpy) for transfer hydrogenation of a variety of quinoxalines, quinoxalinones, quinolines and indoles under aqueous conditions with formate as the hydrogen source is reported. This approach provides various tetrahydroquinoxalines, dihydroquinoxalinones, tetrahydroquinolines and indolines in good to excellent yields. The activity of the catalyst towards quinoxalines and quinoxalinones is excellent, with a substrate to catalyst ratio (S/C) of 10000 being feasible. The choice of ligand is critical to the catalysis, and the aqueous phase reduction is shown to be highly pH-dependent, with acidic pH values needed for optimal reduction. The catalyst is easy to access, and the reaction is operationally simple without requiring an inert atmosphere.

In situ spectroelectrochemical studies of the fluorescence of 5- substituted indole trimer films

A novel in situ spectroelectrochemical cell has been constructed for the simultaneous measurement of fluorescence and current-voltage characteristics during redox cycling. This involves the use of a detachable rotating disc electrode (RDE), which allows the characterisation of luminescent redox active films produced electrochemically under controlled hydrodynamic conditions. Using this cell, the fluorescence of 5-cyanoindole (CI) and indole-5-carboxylic acid (ICA) films has been measured as a function of redox composition during cyclic voltammetry at slow sweep rates. At faster sweep rates hysteresis has been observed in the recorded fluorescence-charge response, indicative of a structural change in the film. The rate of this structural change appears to be decreased by linking the trimer redox centres in the film and by switching from CI to ICA, consistent with the influence of intertrimer hydrogen bonding. Variation in the observed fluorescence emission as a function of wavelength has also been observed, which gives spatial information on the nature of the film redox reaction. This technique shows potential as a method for probing the kinetics and mechanisms of the reaction of electrochemiluminescent films.

Induction of pH sensitivity on the fluorescence lifetime of quantum dots by NIR fluorescent dyes

Modulation of the fluorescence lifetime (FLT) of CdTeSe/ZnS quantum dots (QDs) by near-IR (NIR) organic chromophores represents a new strategy for generating reproducible pH-sensing nanomaterials. The hybrid construct transfers the pH sensitivity of photolabile NIR cyanine dyes to highly emissive and long-lifetime pH-insensitive QDs, thereby inducing a reproducible FLT change from 29 ns at pH >7 to 12 ns at pH <5. This approach provides an unparalleled large dynamic FLT range for pH sensing at NIR wavelengths.

Identification of Phenoxyalkylbenzimidazoles with Antitubercular Activity

We conducted an evaluation of the phenoxyalkylbenzimidazole series based on the exemplar 2-ethyl-1-(3-phenoxypropyl)-1H-benzo[d]imidazole for its antitubercular activity. Four segments of the molecule were examined systematically to define a structure-activity relationship with respect to biological activity. Compounds had submicromolar activity against Mycobacterium tuberculosis; the most potent compound had a minimum inhibitory concentration (MIC) of 52 nM and was not cytotoxic against eukaryotic cells (selectivity index = 523). Compounds were selective for M. tuberculosis over other bacterial species, including the closely related Mycobacterium smegmatis. Compounds had a bacteriostatic effect against aerobically grown, replicating M. tuberculosis, but were bactericidal against nonreplicating bacteria. Representative compounds had moderate to high permeability in MDCK cells, but were rapidly metabolized in rodents and human liver microsomes, suggesting the possibility of rapid in vivo hepatic clearance mediated by oxidative metabolism. These results indicate that the readily synthesized phenoxyalkylbenzimidazoles are a promising class of potent and selective antitubercular agents, if the metabolic liability can be solved.

Indole-Substituted Benzothiazoles and Benzoxazoles as Selective and Reversible MAO-B Inhibitors for Treatment of Parkinson’s Disease

To develop novel, selective, and reversible MAO-B inhibitors for safer treatment of Parkinson’s disease, benzothiazole and benzoxazole derivatives with indole moiety were designed and synthesized. Most of the synthesized compounds showed inhibitory activities against MAO-B and selectivity over MAO-A. The most active compound was compound 5b, 6-fluoro-2-(1-methyl-1H-indol-5-yl)benzo[d]thiazole with an IC50 value of 28 nM with no apparent effect on MAO-A activity at 10 muM. Based on the reversibility assay, compound 5b turned out to be fully reversible with over 95% of recovery of enzyme activity after washout of the compound. Compound 5b showed a reasonable stability in human liver microsomes and did not affect the activities of CYP isozymes, suggesting an absence of high-risk drug-drug interaction. In an in vivo MPTP-induced animal model of Parkinson’s disease, oral administration of compound 5b showed neuroprotection of nigrostriatal dopaminergic neurons as revealed by tyrosine hydroxylase staining and prevention of MPTP-induced parkinsonism as revealed by motor behavioral assay of vertical grid test. In summary, the novel, reversible, and selective MAO-B inhibitor compound 5b was synthesized and characterized. We propose compound 5b as an effective therapeutic compound for relieving parkinsonism.

PdNPs@P2VP-Fe3O4 organic-inorganic hybrid microgels as a nanoreactor for selective aerobic oxidation of alcohols

The preparation of organic-inorganic hybrid microgels with functional Fe3O4 nanoparticles as the crosslinker and 2-vinyl pyridine (2VP) as the pH-sensitive monomer is reported. Magnetic Fe 3O4 nanoparticles were first synthesized via a redox reaction and then modified with 3-(trimethoxysilyl)propylmethacrylate (TMSPMA) via the silanization. The bonding of multiple TMSPMA monomers on the surface of Fe3O4 nanoparticles renders them as crosslinker. Radical polymerization of 2VP was then carried out with the presence of TMSPMA-modified Fe3O4 nanoparticles, leading to the formation of P2VPFe3O4 hybrid microgels crosslinked with Fe 3O4 nanoparticles. The synthesized hybrid microgels are able to trap metal ions such as Pd2? via complex formation of P2VP with metal ions. The reduction of trapped palladium ions by sodium borohydride led to immobilized-palladium nanoparticles. The synthesized PdNPs@P2VP-Fe 3O4 is employed as a new nanocatalyst toward oxidation reaction of alcohols. In addition, the catalytic activity of metal nanocomposite has been found that can be modulated by the volume transition of microgel structures by pH change for the oxidation reaction of benzyl alcohol. Transmission electron microscopy, thermogravimetric analysis, vibrating sample magnetometer, scanning electron microscopy, X-ray powder diffraction, Atomic absorption and Fourier transform Infrared were then used to characterize the resultant catalyst.
