Chemical and biochemical analyses of one of the most basic nonribosomal peptide synthetases (NRPS) from a Pseudomonas fluorescens strain revealed its striking plasticity. Determination of the potential substrate scope enabled us to anticipate novel secondary metabolites that could subsequently be isolated and tested for their bioactivities. Detailed analyses of the monomodular pyreudione synthetase showed that the biosynthesis of the bacterial pyreudione alkaloids does not require additional biosynthetic enzymes. Heterologous expression of a similar and functional, yet cryptic, NRPS of Pseudomonas entomophila was successful and allowed us to perform a phylogenetic analysis of their thioesterase domains. Nonribosomal peptides are a diverse class of ecologically and clinically relevant natural products. Here, Klapper et al. study one of the simplest bacterial nonribosomal peptide synthetases of different Pseudomonas strains. A single gene, encoding the monomodular pyreudione synthetase, leads to the production of a variety of bioactive alkaloids.

Seven acyclic tetradentate compounds of varying lipophilicity incorporating two nitrogen and two alkyl or aryl phosphinate donors have been prepared and their complexation of divalent ions has been studied in aqueous solution by pH-metric, NMR and electrospray mass spectrometric methods of analysis. The hard phosphinate oxygen donor favours binding to the charge-dense Mg2+ ion but binds copper(II) only very weakly in solution. Nickel and zinc ions do form 1:1 complexes involving significant phosphinate ligation and this donor-atom preference leads to an inversion of the Irving-Williams stability sequence.

A ruthenium-catalyzed arylation reaction of oxa- and azabicyclic alkenes with (hetero)arenes by C-H bond activation has been discovered. The reaction does not require additives and utilizes dioxygen in realizing the catalytic cycle leading to monosubstituted 7-oxa and 7-azabenzonorbornane derivatives.

Characterisation of the products of reactions of the Co(III) complex of a quadridentate amine incorporating an azetidine ring by structural crystallography has shown the bound heterocyclic ring to be stable under quite forcing conditions. With bidentate co-ligands, the tetramine appears to prefer one form of “cis-beta” coordination to Co(III). On Cu(II), the tetramine is readily and stereoselectively converted to a macrocycle which may be a useful precursor to pendent-arm derivatives.

Homo- and hetero-dinuclear nickel(II), copper(II), and oxidovanadium(IV) complexes of a Schiff-base-fused phthalocyanine (pc) with bulky substituents, 2,6-dimethylphenoxy and t-butyl groups, were prepared and characterized. The introduced salen-like Schiff-base unit was shown to affect the spectral feature based on the pc unit in the near infrared region, the Q band being widely split over 600-800 nm. A fairly large ferromagnetic interaction (J = 6.0 cm -1) was observed for the CuII(pc)-CuII(salen) homo-dinuclear complex, while an antiferromagnetic interaction (J = -3.2 cm -1) was observed for the CuII(pc)-VIVO(salen) hetero-dinuclear complex.

Synthetic Route of 50446-44-1, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.50446-44-1, Name is 5′-(4-Carboxyphenyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid, molecular formula is C27H18O6.

This article aims to provide an overview of broad range of applications of synchrotron scattering methods in the investigation of nanoscale materials. These scattering techniques allow the elucidation of the structure and dynamics of nanomaterials from sub-nm to micron size scales and down to sub-millisecond time ranges both in bulk and at interfaces. A major advantage of scattering methods is that they provide the ensemble averaged information under in situ and operando conditions. As a result, they are complementary to various imaging techniques which reveal more local information. Scattering methods are particularly suitable for probing buried structures that are difficult to image. Although, many qualitative features can be directly extracted from scattering data, derivation of detailed structural and dynamical information requires quantitative modeling. The fourth-generation synchrotron sources open new possibilities for investigating these complex systems by exploiting the enhanced brightness and coherence properties of X-rays.

We report a rapid, one-pot, operationally simple, and scalable preparation of valuable cationic heteroleptic iridium(III) polypyridyl photosensitizers. This method takes advantage of two consecutive microwave irradiation steps in the same reactor vial, avoiding the need for additional reaction purifications. A number of known heteroleptic iridium(III) complexes are prepared in up to 96% yield. Notably, this method is demonstrated to provide the synthetically versatile photosensitizer [Ir(ppy)2(dtbbpy)]PF6 in >1 g quantities in less than 5 h of bench time. We envision this method will help accelerate future developments in visible-light-dependent chemistry.

Electric Literature of 1941-30-6, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1941-30-6, name is Tetrapropylammonium bromide. In an article，Which mentioned a new discovery about 1941-30-6

Intracrystalline mesoporosity can be conveniently introduced in zeolites using cationic surfactants in a mild basic solution -a process known as surfactant-templating. However, this technique is limited to small-headed and single-chain surfactants because they need to diffuse through the narrow micropores of the zeolite, which limits the potential of this approach. Herein, we show that the mesoporosity generated in zeolites with small-headed and single-chain surfactants, such as CTAB, provides enough accessibility to allow the use of bulky surfactants that otherwise cannot enter the structure of the zeolite. Moreover, in this contribution, a USY zeolite has been successively treated with cationic surfactants of different chain lengths (C12 to C22) proving that the mesopores introduced in the zeolite can be efficiently widened and narrowed by consecutive treatments with surfactants of the suitable size. Finally, the use of consecutive surfactant-templating opens up the possibility of using surfactants of different packing parameters to produce new hierarchical architectures in zeolites.

Background: Now-a-days, discovery of bioactive compounds of plant origin is playing very important role in treatment of various ailments without any side effect world widely. Since, time immemorial, plants have been utilized as a source of Traditional System of Medicine and in India, one of the well known system is Ayurvedic System of Medicine that has been flourishing since thousands years for treatment of allergy, asthma and other inflammatory diseases. Objectives: To inhibit leukotrienes by a purified fraction of Ocimum tenuiflorum in HL- 60 cell lines. To investigate anti-inflammatory activities of a purified Fraction of Ocimum tenuiflorum in an OVA induced asthma model in BALB/c mice. Methods: Plant materials of Ocimum tenuiflorum whole plants were collected after identification and authentication from Vidisha, (M.P.), India and were shade dried, pulverized to powder and extracted after de-fatting in MEOH and DCM and then tested for LTC4, LTA4 and COX-2 inhibitory activities in HL-60 Cell lines. RTPCR was performed to determine the LTC4-synthase mRNA expression. The bio-active purified fraction PM-OT was then tested in vivo in an OVA-induced asthma model in BALB/c mice and inhibition of inflammation was assessed via in vivo imaging tomography. Results: The PM-OT inhibited activities of LTC4 by 52%, LTA4 by 25% and COX-2 by 99% in HL-60 cells and LTC4-synthase mRNA expression in HL-60 Cells. Intra-gastric administration of PM-OT at 100mg/kg body weight along with HPMC led to a reduction in an OVA-induced lung inflammation in asthma model in BALB/c mice. Conclusion: A purified PM-OT fraction showed significant anti-inflammatory activities both in vitro and in vivo, which supported its traditional use in the treatment of inflammatory lung disease and asthma.
