Facile approach to benzo[d]imidazole-pyrrolo[1,2-a]pyrazine hybrid structures through double cyclodehydration and aromatization and their unique optical properties with blue emission

A modular approach to polycyclic N-fused heteroaromatics is described. Acid-catalyzed reactions of various 1-(2-oxo-2-arylethyl)-1H-pyrrole-2-carbaldehydes with several o-phenylenediamines provided facile access to a number of new benzo[d]imidazole-pyrrolo[1,2-a]pyrazine hybrid structures through double cyclodehydration and aromatization. Optical characterization of the synthesized compounds revealed unique emission properties, with deep blue emission in the aggregated and solid states, and a dramatic substituent effect was observed. Fusion of an additional benzene ring into the benzo[4,5]imidazo[1,2-a]pyrrolo[2,1-c]pyrazine scaffold resulted in a remarkable increase in the intensity of blue fluorescence from the solution along with good cell permeability and negligible phototoxicity, indicating the potential for bioimaging applications.

Impact of the alkaloid colletotrichumine A on the pathogenicity of Colletotrichum capsici in Capsicum annum L

Herein we report a study examining the effects of colletotrichumine A, an indole-pyrazine alkaloid isolated from the anthracnose pathogen Colletotrichum capsici, on chilli plants. A colletotrichumine A-pathogen combination was more toxic to the host than individual inoculations of colletotrichumine A or the pathogen. The colletotrichumine A-pathogen combination led to an increased activity of defense related enzymes viz. PPO and SOD, while levels of the lignification enzymes PAL and PO decreased. Higher levels of phenols including catechin and ferulic acid were also observed with the colletotrichumine A-pathogen combination compared to individual treatment. The likely role of colletotrichumine A during chilli anthracnose infection is supported by histochemical analysis of infected plants that showed increased cell death after infection.

Many-photon excitation of organic molecules in a cavity-Superradiance as a measure of coherence

Coherent excitation of a molecular ensemble coupled to a common radiation mode can lead to the collective emission of radiation known as superradiance. This collective emission only occurs if there is an entanglement between the molecules in their ground and excited state and can, therefore, serve as a macroscopic measure of coherence in the ensemble. Reported here are wave packet propagations for various pyrazine models of increasing complexity and molecular ensembles thereof. We show that ensemble coherence upon photoexcitation can prevail up to relatively long time scales although the effect can diminish quickly with increasing ensemble size. Coherence can also build up over time and even reemerge after the molecules have passed through a conical intersection. The effect of the pump pulse characteristics on the collective response of the molecular ensemble is also studied. A broadband pulse imprints a large amount of initial coherence to the system, as compared to a longer pulse with a smaller spread in the frequency domain. However, the differential effects arising from a different pulse duration and coherent bandwidth become less prominent if the emission of light from the ensemble takes place after a non-adiabatic decay process.

Phomopsis tersa as Inhibitor of Quorum Sensing System and Biofilm Forming Ability of Pseudomonas aeruginosa

Endophytic fungi provide rich reservoir for novel antimicrobial compounds. An endophytic fungus, from Carica papaya plant identified as Phomopsis tersa, was investigated for attenuating the quorum sensing mediated pathogenicity of Pseudomonas aeruginosa PAO1. Crude extract of P. tersa was found to reduce the production of redox-active pigments-pyocyanin and pyoverdine in P. aeruginosa PAO1 by 92.46% and 71.55%, respectively at sub-MIC concentration of 900 mu g/mL. In addition, the crude extract was also able to inhibit the expression of virulence factors involved in biofilm formation: exopolysaccharide (72.21%) and alginate (72.50%). Secretion of cell-lytic enzymes was also found to be reduced: chitinase by 79.73% and elastase by 74.30%. 3-Isobutylhexahydropyrrolo[1,2-a]pyrazine-1,4-dione identified from GC-MS analysis, displayed favorable molecular interactions with P. aeruginosa transcriptional regulators, LasR and RhlR with good docking scores of – 6.873 kJ/mol and – 6.257 kJ/mol, respectively. The study thus reveals the potential use of P. tersa for discovering drugs against infectious pathogens.

A Coplanar pi-Extended Quinoxaline Based Hole-Transporting Material Enabling over 21 % Efficiency for Dopant-Free Perovskite Solar Cells

Developing dopant-free hole transporting materials (HTMs) is of vital importance for addressing the notorious stability issue of perovskite solar cells (PSCs). However, efficient dopant-free HTMs are scarce. Herein, we improve the performance of dopant-free HTMs featuring with a quinoxaline core via rational pi-extension. Upon incorporating rotatable or chemically fixed thienyl substitutes on the pyrazine ring, the resulting molecular HTMs TQ3 and TQ4 show completely different molecular arrangement as well as charge transporting capabilities. Comparing with TQ3, the coplanar pi-extended quinoxaline based TQ4 endows enriched intermolecular interactions and stronger pi-pi stacking, thus achieving a higher hole mobility of 2.08×10(-4) cm(2) V-1 s(-1). It also shows matched energy levels and high thermal stability for application in PSCs. Planar n-i-p structured PSCs employing dopant-free TQ4 as HTM exhibits power conversion efficiency (PCE) over 21 % with excellent long-term stability.

Heterocycle-appended lanthanum(III) sandwich-type (porphyrinato) (phthalocyaninates)

An approach to a new type of hetemleptic triple-decker lanthanide (porphyrinato)(phthalocyaninates) bearing functionalized heterocycle-appended low-symmetry porphyrin ligands is developed. The first representatives of such sandwich-type complexes based on porphyrins fused with imidazole or pyrazine cycle are synthesized and precisely characterised. The influence of the nature of the appended 5- or 6-membered heterocyclic fragments onto the electronic properties of complexes is revealed by means of UV-vis spectroscopy. It is found, that the annulation of pyrazine heterocycle results in the expansion of the aromatic system of the ligand, while the annulation of imidazole reveals vanishing influence onto the electronic structure of the molecule. The structural peculiarities originating from the low symmetry of the prepared sandwich-type complexes is investigated in details by NMR.

Bacillus velezensis PEA1 Inhibits Fusarium oxysporum Growth and Induces Systemic Resistance to Cucumber Mosaic Virus

Bacillus velezensismanifests robust biocontrol activity against fungal plant pathogens; however, its antiviral activity has rarely been investigated.Bacillus velezensisstrain PEA1 was isolated, characterized, and evaluated for antifungal and antiviral activities againstFusarium oxysporumMT270445 and cucumber mosaic virus (CMV) MN594112. Our findings proved that strain PEA1 had intense antagonist activity againstF.oxysporum. Under greenhouse conditions, the antiviral activities (protective, curative, and inactivation) of PEA1-culture filtrate (CF) onDatura stramoniumplants were assayed, using a half-leaf method. The inactivation treatment exhibited the highest inhibition rate (97.56%) and the most considerable reduction ofCMV-CPaccumulation levels (2.1-fold) in PEA1-CF-treated plants when compared with untreated plants (26.9-fold). Furthermore, PEA1-CF induced systemic resistance with significantly elevated transcriptional levels ofPAL,CHS,HQT,PR-1, andPODgenes inD.stramoniumleaves after all treatments. Gas chromatography-mass spectrometry analysis showed that pyrrolo[1,2-a]pyrazine-1,4-dione is the main compound in the PEA1-CF ethyl acetate extract, which may act as an elicitor molecule that induces plant systemic resistance and inhibits both fungal growth and viral replication. Consequently,B. velezensiscan be considered as a potential source for the production of bioactive compounds for the management of plant diseases. To our knowledge, this is the first report of the antiviral activity ofB.velezensisagainst plant viral infection.

Construction of a Zn(II)-containing MOF for highly selective detection of picric acid and inhibition of human glioma cell growth

A novel Zinc-based metal-organic framework [Zn-2(OH)(2)(H2TCPP)](DMF)(3) (1) was constructed by using a novel rigid symmetric tetracarboxylic connector, 2,3,5,6-tetrakis (4-carboxyphenyl)pyrazine (H4TCPP). The cross-linkage of Zn(II)-based 1D rod secondary building units (SBUs) with the H2TCPP2- ligands leads to the 3D channel structure of sea-type net with (6,8)-connected topology. Complex 1 not only exhibited the bright blue luminescence induced by H2TCPP2- ligand matrix coordination emission, but also effectively detected picric acid in solution whose quenching constant is 6.95 x 10(4) M-1. Next, the inhibitory effect of complex 1 on various types of cancer cell lines was detected via CCK-8 method. The influence of complex 1 on the U251 human glioma cells invasion, migration and proliferation ability was further explored via transwell method. (C) 2019 Published by Elsevier B.V.

New Donor-Acceptor polymers with a wide absorption range for photovoltaic applications

For conjugated polymers of interest in photovoltaic applications, control of the bandgap as well as the energy levels of the molecules are of great importance to improve the efficiency and performance of the resulting polymer solar cells. A general tactic for adjusting these properties via modification of the conjugated polymer structure is by using different and chosen molecular groups for copolymerization. This communication presents the synthesis of conjugated donor-acceptor type polymers that have the same benzotrithiophene (BTT) donor and different acceptor units, i.e. DPP and fluoro-carbazole substituted thieno[3,4-b] pyrazine (FCTP) denoted as P(BTT-DPP) (P1) and P(BTT-FCTP) (P2), respectively, and their photovoltaic performance using as donor, and non-fullerene acceptor (PDIF) in the bulk heterojunction active layer. The bandgaps as well as the HOMO and LUMO energy levels are effectively tuned. The P(BTT-FCTPZ) structure exhibits a smaller bandgap as compared to P(BTT-DPP) that results from the lower LUMO energy and higher HOMO energy due to the FCTP unit. Having optimized the active layers, the PSCs that were based on P(BTT-DPP) and P(BIT-FCTPZ gave an overall power conversion efficiency of about 9.77% and 10.97%, respectively, using a wide bandgap PDIF non-fullerene acceptor, and 8.38% and 9.05, respectively, using PC71BM as electron acceptor.
