文摘The basidiomycetes Stereum hirsutum and Boreostereum vibrans are two fungi of the same genus.In this study,chemical investigation on the co-cultures of the two congeneric fungi led to the isolation of eleven new vibralactone derivatives,hirsutavibrins A-K(1-11).The structures of 1-11 were elucidated by extensive NMR and HRESIMS spectroscopic analysis,and computational methods.Hirsutavibrins A(1)and B(2)showed weak cytotoxicity against the human lung cancer cell line A549.Hirsutavibrin D(4)showed moderate anti-nitric oxide activity in murine monocytic RAW 264.7 macrophages.This work not only expands the members of vibralactone derivatives with variable configurations but also opens a new avenue for fungal co-culturing study between congeneric fungi.

文摘This study investigates the dynamics of pneumococcal pneumonia using a novel fractal-fractional Susceptible-Carrier-Infected-Recovered model formulated with the Atangana-Baleanu in Caputo(ABC)sense.Unlike traditional epidemiological models that rely on classical or Caputo fractional derivatives,the proposed model incorporates nonlocal memory effects,hereditary properties,and complex transmission dynamics through fractalfractional calculus.The Atangana-Baleanu operator,with its non-singular Mittag-Leffler kernel,ensures a more realistic representation of disease progression compared to classical integer-order models and singular kernel-based fractional models.The study establishes the existence and uniqueness of the proposed system and conducts a comprehensive stability analysis,including local and global stability.Furthermore,numerical simulations illustrate the effectiveness of the ABC operator in capturing long-memory effects and nonlocal interactions in disease transmission.The results provide valuable insights into public health interventions,particularly in optimizing vaccination strategies,treatment approaches,and mitigation measures.By extending epidemiological modeling through fractal-fractional derivatives,this study offers an advanced framework for analyzing infectious disease dynamics with enhanced accuracy and predictive capabilities.
文摘5-Hydroxymethylfurfural(HMF)and its oxidation derivatives have emerged as a bridge between biomass resources and the future energy industry.These renewable biomass resources can be transformed into a variety of value-added chemicals,thereby addressing the challenges posed by diminishing fossil fuel reserves and environmental concerns.The immobilization of catalysts represents an innovative method for the sustainable and efficient synthesis of HMF and its oxidation derivatives.This method not only enhances the yield and selectivity of the products but also allows for the optimization of the catalytic performance of immobilized catalysts through the strategic design of their supports.In this review,we provide an overview of the recent advancements in the technology of immobilized catalyst and its application in the synthesis of HMF and its oxidation derivatives,with a particular focus on the preparation and catalytic characteristics of these immobilized catalysts.Furthermore,we discuss potential future directions for the development of immobilized catalysts,including the preparation of high-performance immobilized catalysts,the exploration of their growth and catalytic mechanisms,and the economic implications of raw material utilization.This area of research presents both significant promise and considerable challenges.

文摘High-energy-density(HED)fuel(e.g.widely used JP-10 and RJ-4),featuring compact 3D polycyclic structure with high strain,is of critical importance for volume-limited military aircraft,since their high density and combustion heat can provide more propulsion energy.To reduce the reliance on petroleum source,it is highly desirable to develop renewable alternatives for the production of strained polycyclic HED fuel,but which remains a big challenge because of the inaccessibility caused by the high strain,We herein demonstrate a three-step catalytic route towards highly strained C_(17)and C_(18)spirofuel with biomass feedstocks.The process includes catalytic aldol condensation of renewable cyclohexanone/cyclopentanone with benzaldehyde,catalytic spiro Diels-Alder(D-A)reaction of aldol adduct with isoprene,and catalytic hydrodeoxygenation.The key spiro D-A reaction is enabled by the catalysis of heterogeneous Lewis acidic ionic liquid.The chloroaluminate IL,formed by benign urea and AICl3,exhibits good catalytic performance and reusability for this step.An eventual hydrodeoxygenation(HDO)over Pd/C and H-Y produces strained tricyclic spirofuel with density>0.93 g/mL,combustion heat>41 MJ/L and freezing point<-40℃,which are better than the properties of tactical fuel RJ-4.Therefore,it is anticipated that the as-prepared renewable fuels have the potential to replace traditional petroleum-derived HED fuels.

文摘Derivatives of metal-organic frameworks(MOFs)are a promising bifunctional electrocatalysts in electrochemical advanced oxidation processes(EAOPs).These metal/carbon materials overcome the limitations of individual components by creating synergistic effects.EAOPs is primarily constrained by the generation and activation of H_(2)O_(2).This article examines the regulatory strategies employed in MOFs derivatives to enhance the production of H_(2)O_(2)via 2e^(-)pathways and its activation to·OH,focusing on preparation techniques,structures,and compositions.The design of these derivatives involves methods such as metal dispersion on the surface of nanocarbons,embedding in carbon shells,and atomic dispersion of metals anchored in porous carbon.MOFs derivatives promote·OH production and enhance wastewater purification through mechanisms such as boosting the Fe(Ⅱ)/Fe(Ⅲ)cycle,facilitating direct 3e^(-)reactions of O_(2),and interacting of O_(2)^(·-).Moreover,the performance and durability of MOFs derivatives in wastewater treatment,particularly in influencing·OH generation within EAOPs,were investigated.This review addresses current challenges and future prospects,offering valuable insights for the development of MOFs derivatives as 3e^(-)ORR electrocatalysts and the advancement of sustainable water treatment technologies.

文摘Goji berry is a famous edible and medicinal substance around the world.In this research,15 phenylpropionyl phenylethylamine derivatives(1-15),in cluding one new compound(1),were separated and identified from g oji berry.All isolates were elucidated via ex tensive nuclear magnetic resonance spectral analyses and chemical techniques.Six known isolates were first obtained from Lycium genus.Six isolates were effectively split in to double chromatographic peaks accompanied by the basically identical areas,indicating they belong to racemates.The oxygen radical absorbance capacity(ORAC)experiment indicated that all isolates displayed a capacity of scavenging free radicals,and most of them exhibited higher ORAC than epigallocatechingallate.In ethanol/palmitic acid-established in vitro hepatocyte injury model,four phenylpropionyl phenylethylamine derivatives(1,2,9,and 15)significantly alleviated hepatocyte injury,among which compound 1 exerted the strongest protective activity.Notably,the hepatoprotective effect of compound 1 was further confirmed in ethanol-established liver damage mouse model,reflected by the reduction of lipid accumulation and the attenuation of pathological alteration.Combined with the in vitro results,the in vivo observations suggested that compound 1 suppressed cell apoptosis and the outburst of inflammation.Our findings provided first-hand evidence proving that goji berry-derived phenylpropionyl phenylethylamine derivatives hold a potential in treating alcoholic liver disease.

文摘Saponins associated with Panax notoginseng(P.notoginseng)demonstrate significant therapeutic efficacy across multiple diseases.However,certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy.This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro.The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects.Structure-activity relationships(SARs)analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity.Additionally,several other derivatives exhibit general adipogenesis inhibition.Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1.Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro,accompanied by decreased expression of preadipocytes.Peroxisome proliferator-activated receptorγ(PPARγ),fatty acid synthase(FAS),and fatty acid binding protein 4(FABP4)adipogenesis regulators.These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders.This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.

文摘Natural products are the important sources in cardiovascular drug development.In this study,twenty-nine buthutin derivatives were designed,synthesized,and evaluated for their NHE-1 inhibition and protective effects on cardiomyo-cyte injury.The structure of the newly synthesized compounds had been confirmed by 1H-NMR,13C-NMR,and HR-ESI-MS spectra.Among all target compounds at 1μM,compounds 9d,9f,9k,9m,and 9n,with a protection ratio exceeding 30%,exerted stronger protective effects on H9c2 cardiomyocyte than positive control dexrazoxane and buthutin A.Meanwhile,compounds 9k,9m,and 9o showed the significant NHE-1 inhibitory activities on H9c2 cardiomyocyte,all with a dpHi/min value less than 0.23.What is more,compounds 9k,9m,9o and buthutin A all exhibited the specificity on NHE-1 inhibition.Molecular modelling studies suggested the ability of compounds 9m and 9o to establish interactions with three hydrogen bonds to Asp267 and Glu346 of NHE-1,but also the ability with much lower CDOCKER energies than positive control cariporide and buthutin A.The structure-activity relationship(SAR)studies suggested that the presences of amide group,four-carbon linker,and para hydroxyl benzene ring were advantageous pharmacophores for above two pharmacological actions.This research would open new avenues for developing amide-guanidine-based cardioprotective agents.

文摘Amino acids have emerged as promising green alternatives to replace toxic inhibitors in corrosion protection applications.In this study,we present a one-step synthetic approach to get 4-(tert-butyl)benzoyl)methionine(P-Meth)and 4-(tert-butyl)benzoyl)cysteine(P-Cys)through the acylation reactions between methionine or cysteine and p-tert-butylbenzoic acid,respectively,which exhibit a super protective performance toward metals against corrosion.The corrosion rates of Q235 steel in 1 M HCl were reduced from 4.542 to 0.202and 0.312 mg·h^(-1)·cm^(-2)in the presence of 100 mg·L^(-1)P-Meth and P-Cys,respectively.The surface structures of Q235 steel remained unbroken after 12 h in 1 M HCl medium.The charge transfer resistances of corrosion reactions were enhanced by 12 and 9 times in the presence of P-Meth and P-Cys,respectively.P-Meth and P-Cys were adsorbed onto the Q235 steel via chemical actions,which were accompanied by minimal physical action.Molecular dynamic simulations demonstrate the higher binding energy of P-Meth onto Q235 steel than P-Cys.The study contributes to the corrosion protection of metals with green and environmentally friendly methods.
