Dipodal silanes possess two silicon atoms that can covalently bond to a surface. They offer a distinct advantage over conventional silanes commonly used for surface modification in terms of maintaining the integrity of surface coatings, adhesive primers, and composites in aqueous environments. New nonfunctional and functional dipodal silanes with structures containing "pendant" rather than "bri...

A novel polyfunctional dipodal ligand, L = N,N'-bis[2-[(2-hydroxy-1-naphthyl)methyleneamino]ethyl]propanediamide (DOTA2HNAP) was developed and characterized through elemental and spectral analyses. The complexation behavior of the ligand was investigated with Co2+, Cu2+, and Zn2+ metal ions by potentiometric and spectrophotometric methods in H2O-D...

Bu çalışmada çıkış maddesi olarak siyanür klorür kullanıldı. Siyanür klorür, literatürde verilen metotlardan faydalanılarak asetonlu ortamda farklı klor uçlarından 5-hidroksiizoftalik asit kullanılarak 0 oC bir yönlü (monopodal) 2,4-dikloro-6-(3,5-dikarboksifenoksi)-1,3,5-triazin (MNCHIPA) ve oda sıcaklığında iki (dipodal) 2-kloro-4,6-(2,5-dikarboksifenilfenoksi)-1,3,5-triazin (DPCHIPA) bileşik...

The synthesis of a novel dipodal ligand framework, H2[(Me)N(pi(Cy))2], is summarized. Upon metalation with MCl2 salts (M = Fe, Cu), the ligand undergoes a conformational change, resulting in the formation of a trigonal bipyramidal metal center with a pseudoplanar, meridionally-bound ligand framework. This tautomerization positions pendant amines in the metal's secondary coordination sphere. Met...

transfusion in the treatment of thalassemia gives rise to iron deposits in many organs. since there are many obstacles in the use of deferoxamin (dfo) as an iron chelating agent, it is important to find another alternative therapy that can act as iron chelation. the study aims to compare the histopathological pictures of the heart and spleen in iron-induced rats after administration of dfo and ...

transfusion-dependent patients such as those suffering from β-thalassaemia develop a fatal secondary haemosiderosis and consequently a selective iron chelator must be used to relieve such iron overload. 3- hydroxypyridin-4-ones are selective for iron(iii) under most biological conditions, but unlike desferrioxamine, are efficiently absorbed when administered orally. in this study, the synthesis...
