To investigate the role of leading saffron endophyte Burkholderia gladioli strain E39CS3 (BG-E39) in inhibition corm-rot and induced systemic resistance (ISR) host against specific pathogen, Fusarium oxysporum.We studied interaction between BG-E39 pathogen F. oxysporum vitro vivo. strongly inhibited both strains other saffron-specific non-specific pathogens used this study. Confrontation microscopic analyses revealed that possessed fungicidal activity effectively cell death mycelia. The...
Syngas (H2 + CO) is a compatible fuel for internal combustion engines, or it can be transformed to liquid fuels, which help overcome future energy crises sustainably. In this study, we report an inexpensive and highly active photocatalytic system production of syngas from formic acid under ambient conditions. The comprising CdS/CNT hybrids porphyrin-based catalyst showed remarkable H2 CO evolution at Using monochromatic light (420 nm), the highest values apparent quantum yields reached 22.8...
Comprehensive Summary TBAJ‐876, developed by TB Alliance, a novel anti‐tuberculosis‐specific drug, has entered Phase II clinical trials. Herein, the first asymmetric synthesis of TBAJ‐876 been realized using synergistic Li/Li catalysis with excellent yield 95% and 88 : 12 er (99.6 0.4 er, 10 1 dr after simple recrystallization). Furthermore, DFT calculations 7 Li‐NMR analysis illustrated mechanism reaction: chiral Li‐complex activates nucleophile to control stereoselectivity, while other...
Efficient silylation reactions of propargyl epoxides catalyzed by copper catalysts have been developed.
Copper-catalyzed conjugate protosilylation reaction of α,β-unsaturated sulfonyl ketimines has been developed. The corresponding E- and Z-stereoselective functionalized allylsilane products were obtained in good yields respectively via tuning the ligands used reactions. Furthermore, highly enantioselective (E)-β-tosylamine-substituted allylsilanes also achieved presence chiral Pybox ligand. And could be easily transformed into other useful synthons.
Coxiellosis caused by Coxiella burnetii is a cosmopolitan zoonosis, which causes significant losses through abortions and stillbirths in small ruminants. A cross-sectional seroprevalence study was conducted two major sheep goat farming districts of Punjab (Layyah Muzaffargarh), Pakistan. In total, 542 ruminants (271 goats each) both sexes (60 males 482 females) different age groups from 104 flocks (52 either species) were randomly selected for the collection sera related epidemiological...
In Pakistan and all over the world, Peach Fruit Fly (PFF), Bactrocera zonata (Saunders.) Melon (MFF), cucurbitae (Coquillett.) are considered severe polyphagous insect pests for various fruits vegetables. The current study was conducted to check Laboratory preference performance of B. on selected Fruits Citrus (Citrus sinensis), Apple (Malus domestica), Banana (Musa acuminate), vegetable, Sponge gourd (luffa aegyptiaca), Bitter (Momordica charantia) Pumpkin (Cucurbita moschata) under...
A general strategy for the hydroalkylation of vinyl ketones using ethers catalyzed by an iron catalyst is described.
Abstract We examine the relationship between financial inclusion and carbon emissions. For this purpose, we develop a composite indicator of based on broad set attributes through principal component analysis (PCA) for 26 countries in Asia region. Our robust panel regression reveals significant positive long-term impact The pairwise causality test unidirectional running from to study suggests that policy makers may design policies integrate accessible systems into climate change adaptation...
To evaluate the antimicrobial potential of Juglomycins isolated from Streptomyces achromogenes E91CS4, an endophyte Crocus sativus Linn.The extract E91CS4 displayed significant activity against several pathogens. The was identified as S. on by 16S ribosomal gene analysis. Chemical investigation led to isolation two naphthoquinone antibiotics, Juglomycin A and B. inhibited pathogens, with MIC value 13·7µg ml-1 , whereas it most potent Escherichia coli, Bacillus thuringiensis Xanthobacter...
The Pd(II)-catalyzed one-pot tandem cyclization/alkylation reactions of enynoates with allylic alcohols have been demonstrated. In this reaction, an innovative protocol proceeded well through Pd-catalyzed intramolecular selective 6- endo cyclization, insertion into the Pd-C bond vinylpalladium species generated in situ, and β-hydrogen elimination processes. This conversion provides a convenient efficient methodology for synthesis 2-alkanone pyrones moderate to good yields.
A Pd(II)-catalyzed mild and highly regioselective 6-endo cyclization/allylation reaction of enynoates with simple allylic alcohols has been developed. Under conditions, the vinyl palladium species generated in situ after cyclization could insert C–C double bond alcohol through cross-coupling lead to formation allyl pyrone via β-OH elimination. This cascade represents a direct atom economic methodology for construction novel pyrones moderate good yields.
A copper-catalyzed regioselective 1,4- and 1,6-conjugate addition of a silyl reagent to diendioates was established.
In the title moleclue, C(13)H(10)N(4)O(3), methyl-idene-hydrazide [-C(=O)-N-N=C-] fragment is essentially planar, with a maximum deviation of 0.0228 (7) Å. The mean planes benzene and pyridine rings make dihedral angles 25.44 (6) 5.47 (7)°, respectively, plane fragment. crystal structure, inter-molecular N-H⋯N hydrogen bonds link mol-ecules into chains along b axis. Additional stabilization provided by weak C-H⋯O bonds. O atoms nitro group are disordered over two sets sites equal occupancy.
Regioselective [3+3] annulation of alkynyl ketimines with α-cyano ketones for the synthesis polysubstituted 4H-pyran derivatives a quaternary CF3 -containing center has been realized by using Cu(OAc)2 as catalyst.
