Synthesis and Catalytic Application of Two Mononuclear Complexes Bearing Diethylenetriamine Derivative Ligand.

Two mononuclear zero-dimensional Ni(II) and Zn(II) complexes bearing diethylenetriamine derivative ligand, namely [NiL(CH3COO)2(H2O)] (1) and [ZnL(CH3COO)2] (2) [L = N, N'-bis(2-hydroxybenzyl)diethylenetriamine], were synthesized under reflux conditions. The molecular composition and structure of the complexes were identified by IR, PXRD, elemental analyses, and single crystal X-ray diffraction. Complex 1 belongs to a monoclinic crystal system with the P21/n space group, and Complex 2 belongs to a monoclinic crystal system with the C2/c space group. The Henry reaction of nitromethane with aromatic aldehydes was explored with Complexes 1 and 2 as the catalyst. Results from the catalytic reaction revealed that the complexes displayed excellent catalytic activities under the optimized conditions and that the substrate scope of aromatic aldehydes could be extended to a certain extent. In addition, the possible catalytic mechanism of the Henry reaction was also deduced.

The miR-875-5p inhibits SATB2 to promote the invasion of lung cancer cells.

The pathogenesis of non-small cell lung cancer (NSCLC) is regulated by various miRNAs. In this study, we identified that miR-875-5pis up-regulated in NSCLC patients, and inhibited SATB Homeobox 2(SATB2) to promote proliferation and invasion of NSCLCcells.CCK-8assay revealed thatmiR-875-5p mimics promoted proliferation of NSCLC cells. Transwell assay showed that miR-875-5pmimicspromoted the invasion and migration of NSCLC cells. Luciferase assays confirmed that miR-875-5pdirectly binds to the 3'untranslated region of SATB2, and western blotting showed that miR-875-5psuppresses the expression of SATB2 at the protein level. Moreover, the inhibitors of miR-875-5pinhibit proliferation and invasion of NSCLC cell lines. The miR-875-5pwouldbe a potential therapeutic target for NSCLC treatment in the future.
