Background: Approximately half of all new cases of gastric cancer (GC) and related deaths occur in China. More than 80% of patients with GC are diagnosed at an advanced stage, which results in poor prognosis. Although -directed therapy and immune checkpoint inhibitors have been somewhat successful, new drugs are still needed for the treatment of GC.
View Article and Find Full Text PDFTwo new mononuclear Fe(II) complexes, [FeL1(NCBH3)2] (1) and [FeL2(CN)2]·3H2O (2) (L1 = N,N'-bis(2-pyridylmethyl)-1,2-ethanediamine, L2 = N-(2-pyridylmethyl)-N'-(2-pyridylmethylene)-1,2-ethanediamine) were synthesized from the same starting solution under different atmospheric conditions. Complex 1 was isolated under an N2 atmosphere with an expected molecular structure, namely a tetradentate L1 ligand and two NCBH3(-) co-ligands wrapping an iron(ii) ion. It exhibits a gradual spin crossover centered around 355 K, as confirmed by X-ray crystallography, magnetic, DSC and Mössbauer studies.
