摘要

A robust synthesis of magnetic NiFe2O4 nanoparticles via a hydrothermal technique was investigated. The prepared magnetic NiFe2O4 nanoparticles were characterized using powder X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM, energy-dispersive X-ray spectroscopy, thermogravimetric analysis, infrared spectroscopy and vibrating sample magnetometry. XRD and TEM analyses confirmed the formation of single-phase ultrafine nickel ferrite nanoparticles with highly homogeneous cubic shape and elemental composition. Moreover, the prepared magnetic NiFe2O4 nanoparticles were used as an efficient, cheap and eco-friendly catalyst for the Claisen-Schmidt condensation reaction between acetylferrocene and various aldehydes (aromatic and/or heterocyclic) yielding acetylferrocene chalcones in excellent yields, with easywork-up and reduced reaction time. The productswere purified via crystallization. The structures of the produced compounds were elucidated using various spectroscopic analyses (H-1 NMR, C-13 NMR, GC-MS). The catalyst is readily recovered by simple magnetic decantation and can be recycled several times with no discernible loss of catalytic activity. Furthermore, the prepared chalcone derivatives were evaluated for their anti-tumour activity against three human tumour cell lines, namely HCT116 (colon cancer), MCF7 (breast cancer) and HEPG2 (liver cancer), and showed a good activity against colon cancer.

Summary: A set of 22 analogs of licochalcone A was designed and synthesized to explore their potentials as dipeptidyl peptidase 4 (DPP4) inhibitors with anti-inflammatory effects. The most potent activity was exhibited by the nitro-substituted analogue 27. The structure-activity relationship investigation revealed the importance of 4-hydroxyl and 5-chloro substituents for DPP4 inhibition, while the 3'-nitro substituent improved both DPP4 inhibition and microsomal stability. Furthermore, compound 27 showed good selectivity for DPP4 over other proteases and demonstrated no toxicity to normal cells and weak toxicity to cancer cells.

2D RGO nanosheets supported anti-spinel NiFe2O4 nanocubes for efficient hydroxylation of phenol

Yitao Zhao, Lei Tao, Yan Nie, Zhiyong Qiao, Changming Ding

Summary: A novel nanocomposite of anti-spinel NiFe2O4 nanocrystals and reduced graphene oxide (RGO) was successfully developed for enhancing the hydroxylation of phenol. The optimal NiFe2O4-RGO(20) catalyst exhibited a phenol conversion of 28.2%, a selectivity of 93.3%, and a molar ratio of catechol to hydroquinone of 2.6. The catalyst maintained good activity after 6 reaction cycles, and its superior performance was attributed to the uniform dispersion of NiFe2O4 nanocrystals on the RGO surface, which prevented sheet stacking and increased active site exposure. Additionally, the NiFe2O4-RGO(20) composite accelerated the decomposition of H2O2 into & BULL;OH, thereby improving the reaction efficiency of phenol hydroxylation.
