Thermally Induced Spin Transition in a 2D Ferrous Nitroprusside

This study reports the intercalation of pyridine molecules between neighboring layers of two-dimensional (2D) ferrous nitroprusside. In the material under study, the stacking of neighboring layers results in the formation of a long range ordered solid, where the 3D structure is supported by dipole-dipole attractive interactions between neighboring pyridine molecules in the interlayer region. No chemical interactions were observed between layers, which preserve their identity as a 2D material. In this hybrid inorganic-organic solid, a thermal induced spin transitions from high to low spin on cooling and then from low to high spin on heating were observed. Such thermal induced spin crossover transition takes place with a pronounced hysteresis of 18 K, according to the magnetic and DSC measurements. That spin crossover transition is characterized by an extremely small structural change, involved a unit cell volume reduction from the high to low spin states of only 0.7 % and a related Fe-N-Pyridine distance shortening of 0.10 angstrom. The two spin states and the transition between them were additionally characterized from magnetic and DSC data and, Raman and Mossbauer spectra.

Delocalization tunable by ligand substitution in [L2Al](n-) complexes highlights a mechanism for strong electronic coupling

Ligand-based mixed valent (MV) complexes of Al(III) incorporating electron donating (ED) and electron withdrawing (EW) substituents on bis(imino)pyridine ligands (I2P) have been prepared. The MV states containing EW groups are both assigned as Class II/III, and those with ED functional groups are Class III and Class II/III in the (I2P-)(I2P2-)Al and [(I2P2-)(I2P3-)Al](2-) charge states, respectively. No abrupt changes in delocalization are observed with ED and EW groups and from this we infer that ligand and metal valence porbitals are well-matched in energy and the absence of LMCT and MLCT bands supports the delocalized electronic structures. The MV ligand charge states (I2P-)(I2P2-)Al and [(I2P2-)(I2P3-)Al](2-) show intervalence charge transfer (IVCT) transitions in the regions 6850-7740 and 7410-9780 cm(-1), respectively. Alkali metal cations in solution had no effect on the IVCT bands of [(I2P2-)(I2P3-)Al](2-) complexes containing -PhNMe2 or -PhF5 substituents. Minor localization of charge in [(I2P2-)(I2P3-)Al](2-) was observed when -PhOMe substituents are included.

Disclosing proteins in the leaves of cork oak plants associated with the immune response to Phytophthora cinnamomi inoculation in the roots: A long-term proteomics approach

The pathological interaction between oak trees and Phytophthora cinnamomi has implications in the cork oak decline observed over the last decades in the Iberian Peninsula. During host colonization, the phytopathogen secretes effector molecules like elicitins to increase disease effectiveness. The objective of this study was to unravel the proteome changes associated with the cork oak immune response triggered by P. cinnamomi inoculation in a long-term assay, through SWATH-MS quantitative proteomics performed in the oak leaves. Using the Arabidopis proteome database as a reference, 424 proteins were confidently quantified in cork oak leaves, of which 80 proteins showed a p-value below 0.05 or a fold-change greater than 2 or less than 0.5 in their levels between inoculated and control samples being considered as altered. The inoculation of cork oak roots with P. cinnamomi increased the levels of proteins associated with protein-DNA complex assembly, lipid oxidation, response to endoplasmic reticulum stress, and pyridine-containing compound metabolic process in the leaves. In opposition, several proteins associated with cellular metabolic compound salvage and monosaccharide catabolic process had significantly decreased abundances. The most significant abundance variations were observed for the Ribulose 1,5-Bisphosphate Carboxylase small subunit (RBCS1A), Heat Shock protein 90-1 (Hsp90-1), Lipoxygenase 2 (LOX2) and Histone superfamily protein H3.3 (A8MRLO/At4G40030) revealing a pertinent role for these proteins in the host-pathogen interaction mechanism. This work represents the first SWATH-MS analysis performed in cork oak plants inoculated with P. cinnamomi and highlights host proteins that have a relevant action in the homeostatic states that emerge from the interaction between the oomycete and the host in the long term and in a distal organ.

A novel Cd-II-based metal-organic framework as a multi-responsive luminescent sensor for Fe3+ MnO4-, Cr2O72-, salicylaldehyde and ethylenediamine detection with high selectivity and sensitivity

A novel luminescent Cd-I-based metal-organic framework {[Cd(BBIP)(TBIP)]center dot EtOH}(n) (1) derived from the multidentate 5-tert-butylisophthalic acid (H2TBIP) and the semi-rigid N-donor 3,5-bis(benzimidazol-1-yl) pyridine (BBIP) has been solvothermally synthesized and structurally characterized by using infrared spectroscopy, thermal analysis, single-crystal X-ray diffraction and powder X-ray diffraction. The adjacent Cd-II ions are linked by two carboxylate groups of one TBIP2- ligand with chelating mode to form a one-dimensional Cd-II-TBIP2- chain, which is further connected by the BBIP ligand to obtain a two-dimensional network. Interestingly, the fluorescence experiments indicate that 1 could be considered as a good multiresponsive sensing material for detecting Fe3+, MnO4-, Cr2O72-, salicylaldehyde (SA) and ethylenediamine (EDA) via the turn-off effect, with the detection limits of 0.53, 0.98, 3.6, 0.42 and 5.3 ppm, respectively. The luminescence quenching effect induced by Fe3+ could be mainly ascribed to the competitive absorption mechanism. The electron-transfer transition and competitive absorption mechanism could be used to explain the luminescence quenching of MnO4- and Cr2O72-. The turn-off effect of 1 on SA could be ascribed to the photoinduced electron-transfer and competitive absorption mechanisms. Meanwhile, the possible mechanism of fluorescence quenching caused by EDA could be attributed to the structure collapse. More importantly, 1 could be regenerated and reused after five cycles for Fe3+, MnO4-, Cr2O72- and SA detection. In a nutshell, 1 could be employed as a multi-responsive luminescent sensor used for the highly selective and sensitive detection of metal ions, anions and small organic molecules.

An expeditious microwave assisted one-pot sequential route to pyrido fused imidazo[4,5-c] quinolines in green media

An expeditious microwave assisted one-pot sequential route to synthesize pyrido fused imidazo[4,5-c]quinolines via the Pictet-Spengler cyclization strategy has been developed. In this study, substituted 2-amino pyridines are condensed with 2-bromo-2 ‘-nitroacetophenone to generate imidazo[1,2-a]pyridines with nitro group functionality at C-2 position. Reduction of nitro group to its amine congener in green media followed by the Pictet-Spengler cyclization strategy with substituted aldehydes led to the formation of new C-C and C-N bonds in a one-pot sequential manner. The cyclization proceeds through the CO(carbonyl)-C(H) cleavage of the aldehyde group via oxidative cross-coupling, transamination, cyclization and aromatization steps. Low cost reagents and a green solvent were used to facilitate the architecturally beautiful pyrido fused imidazo[4,5-c]quinoline scaffolds in high yields. The key features of this synthetic protocol are the use of microwave-assisted mild reaction conditions, one-pot sequential pathway, broad substrate scope and green media, which make it feasible for the synthesis of fused polyheterocycles. Moreover, the synthetic manipulation proceeded well with heteroaromatic and aliphatic aldehydes also in good yields.

Pyridine-2,6-dicarboxaldehyde-Enabled N-Terminal In Situ Growth of Polymer-Interferon alpha Conjugates with Significantly Improved Pharmacokinetics and In Vivo Bioactivity

Polymer-protein conjugates are a class of biohybrids with unique properties that are highly useful in biomedicine ranging from protein therapeutics to biomedical imaging; however, it remains a considerable challenge to conjugate polymers to proteins in a site-specific, mild, and efficient way to form polymer- protein conjugates with uniform structures and properties and optimal functions. Herein we report pyridine-2,6-dicarboxaldehyde (PDA)-enabled N-terminal modification of proteins with polymerization initiators for in situ growth of poly(oligo(ethylene glycoOmethyl ether methacrylate) (POEGMA) conjugates uniquely at the N-termini of a range of natural and recombinant proteins in a mild and efficient fashion. The formed POEGMA-protein conjugates showed highly retained in vitro bioactivity as compared with free proteins. Notably, the in vitro bioactivity of a POEGMA-interferon alpha (IFN) conjugate synthesized by this new chemistry is 8.1-fold higher than that of PEGASYS that is a commercially available and Food and Drug Administration (FDA) approved PEGylated IFN. The circulation half-life of the conjugate is similar to that of PEGASYS but is 46.2 times longer than that of free IFN. Consequently, the conjugate exhibits considerably improved antiviral bioactivity over free IFN and even PEGASYS in a mouse model. These results indicate that the PDA-enabled N-terminal grafting-from method is applicable to a number of proteins whose active sites are far away from the N-terminus for the synthesis of N-terminal polymer-protein conjugates with high yield, well-retained activity, and considerably improved pharmacology for biomedical applications.

The Groebke-Blackburn-Bienayme Reaction

Imidazo[1,2-a]pyridine is a well-known scaffold in many marketed drugs, such as Zolpidem, Minodronic acid, Miroprofen and DS-1 and it also serves as a broadly applied pharmacophore in drug discovery. The scaffold revoked a wave of interest when Groebke, Blackburn and Bienayme reported independently a new three component reaction resulting in compounds with the imidazo[1,2-a]-heterocycles as a core structure. During the course of two decades the Groebke Blackburn Bienayme (GBB-3CR) reaction has emerged as a very important multicomponent reaction (MCR), resulting in over a hundred patents and a great number of publications in various fields of interest. Now two compounds derived from GBB-3CR chemistry received FDA approval. To celebrate the first 20 years of GBB-chemistry, we present an overview of the chemistry of the GBB-3CR, including an analysis of each of the three starting material classes, solvents and catalysts. Additionally, a list of patents and their applications and a more in-depth summary of the biological targets that were addressed, including structural biology analysis, is given.

Synthesis of New Polyheterocyclic Ring Systems Derived from 3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine

3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine (2) was utilized as a precursor for the construction of new polyheterocyclic ring systems. It reacted with 4-substituted arylidene malononitriles and/or ethyl acetoacetate to furnish the corresponding pyrido[2′,3′:3,4]pyrazolo[1,5-a]pyrimidine derivatives 4a-c and 6, respectively. Diazotization of the precursor 2 followed by coupling with ethyl cyanoacetate was the route for the formation of pyrido[2′,3′:3,4]pyrazolo[5,1-c]triazine derivative 8. The synthesized N-(5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridin-3-yl)-2-cyanoacetamide (10) was utilized for the synthesis of 6-amino-4-aryl-1-(pyrazolo[3,4-b]-pyridin-3-yl)-1,2-dihydropyridines derivatives 12a-c via its treatment with three types of arylidene malononitrile. N-(5-Bromopyrazolo[3,4-b]pyridinyl)-2-(4-oxothiazolidin-2-ylidene)acetamide 13 and N-(5-bromopyrazolo[3,4-b]pyridinyl)-2-cyano-2-(4-oxo-3-phenylthiazolidin-2-ylidene)acetamide 15 were picked up through the reactions of 10 with 2-mercaptoacetic acid and/or Ph-N = C = S with BrCH2COOEt. The tricyclic ring system, 9-bromo-3-cyano-2-oxo-pyrido[2′,3′:3,4]pyrazolo[1,5-a]-pyrimidine derivative 18, was used as building block for the construction of new tetra- and penta-heterocyclic compounds 19, 20, and 21 through its reaction with some bis-nucleophilic reagents; hydrazine hydrate, malononitrile and 4-(4-anisylazo)-1H-pyrazole-3,5-diamine. The newly synthesized pyrazolo[3,4-b]pyridine-based heterocycles were characterized by the IR and H-1 NMR spectral techniques and their in vitro antibacterial properties were evaluated.
