Catalytic upgrading of biomass-based aldehydes into chain-extended intermediates for downstream applications in biofuels, fine chemicals, and renewable materials, is reviewed.
Drug resistance is one of the main hurdles for successful treatment breast cancer. The synchronous targeting apoptosis and survival signal transduction pathways may be a promising approach to overcome drug resistance. In this study, we determined that evodiamine (EVO), major constituent Chinese herbal medicine Evodiae Fructus, could induce doxorubicin (DOX)-sensitive MCF-7 DOX-resistant MCF-7/ADR cells in caspase-dependent manner, as confirmed by significant increases cleaved...
Two highly efficient and recyclable heterogeneous azolium catalyst systems, one grafted (g) onto the inorganic oxide (Silica) other organic polymer [Merrifield's peptide or chloromethylated polystyrene (PS) resin], have been developed employed to catalyze quantitative self-coupling (umpolung condensation) reactions of furfural 5-hydroxymethylfurfural (HMF) into C10 C12 furoins, respectively. Supported benzimidazolium ([BI]) salts bearing a long-chain alkyl substituent (i.e., dodecyl) on...
Osteosarcoma is the second highest cause of cancer-related death in children and adolescents. Majority osteosarcoma patients (90%) show metastasis. Previous reports revealed that osthole showed antitumor activities via induction apoptosis inhibition proliferation. However, potential effects detailed molecular mechanisms involved remained unclear.Cell viability was analyzed by MTT assay cell lines MG-63 SAOS-2. Cell cycle detected flow cytometry. The migration invasion were evaluated wound...
The doping of niobium and the synergistic effect Ni acid sites promote HDO guaiacol. 0 –NiNbO x /SiO 2 is a potential catalyst for producing cycloalkanes from lignin-derived phenolic compounds.
Abstract Phenolic resins (PRs) are known for their exceptional performance due to 3D cross‐linked structure formed during curing. However, this crosslinking makes them non‐reprocessable and difficult recycle, leading significant environmental pollution resource waste. In study, the reactivity of phenolic hydroxyl group in thermoplastic PR (abbreviated as NR) is utilized introduce a highly stable nitrogen‐coordinated cyclic boronic ester (NCB) into traditional carbon‐chain polymers with aid...
Abstract Antibiotics in water body pose a threat to the ecosystem and human health, removal of antibiotics is imperative. Ti 3 C 2 T x has high specific surface area structural stability, but suffers from low catalytic activity insufficient utilization active sites. In this paper, /Bi S composites (named PTB STB, respectively) were prepared by situ synthesis physical composite method. The introduction Bi extends light absorption visible region. Meanwhile, electron migration resistance...
A density functional theory study was performed to understand the detailed mechanisms of cross-benzoin reactions catalyzed by N-heterocyclic carbene (NHC) species.
Evodiamine (EVO) is a plant-derived indolequinazoline alkaloid with potential anticancer activity. However, low bioavailability caused by its poor water solubility limits it efficacy in clinic. To enhance the and improve of EVO, delivery system based on poly (lactic-co-glycolic acid) (PLGA) nanoparticles loaded EVO (EVO-PLGA NPs) for treating breast cancer was prepared this study. The physicochemical characterization vitro antitumor evaluation EVO-PLGA NPs were determined. could persistently...

Isocoumarins are an important pharmaceutical compounds.Many synthetic pathways have been developed, mainly focusing on the cyclization of benzoic acid or other with alkynes.Sulfinylidene benzamides were facilely prepared and developed in chelation-assisted arene ortho-C-H functionalization, vinylene carbonate can establish oxidant-free catalytic system, giving carbonic as a sole side product.In presence rhodium catalyst, annulation between sulfinylidene was proceeding directing...
The upgrading of biomass furaldehydes—furfural (FF) and 5-alkyl (R) substituted furfurals (R = Me, MF; CH2OH, HMF; CH2OMe, MMF)—into C10–14 furoins was achieved by the selective umpolung self-coupling reaction catalyzed polystyrene (PS) supported azolium salts paired with an acetate counterion, which allows a thermal equilibrium between dormant ion pair active N-heterocyclic carbene (NHC) states. By regulating heating to generate sufficient amounts form catalyst for catalysis cooling...
Methods developed with N-(benzoyloxy)amines and hydroxamic acids were used in the synthesis of N-(hydroxy)amide-containing pseudopeptides.

Polycyclic xanthones are characterized by highly oxygenated, angular hexacyclic frameworks and exhibit diverse biological activities. Although many of them have been isolated chemically synthesized, the detailed biosynthetic machinery awaits discovery. Recently, xanthone construction in xantholipin (1) pathway was shown to involve cryptic demethoxylation. This suggested a rationale for existence three O-methyltransferase (OMT) genes gene cluster, although there only two O-methyl groups...
