The synthesis of carboxamido-functionalised heterocycles via homogeneous catalytic reactions is planned. Homogeneous thio- and selenocarbonylations will be carried out by using either CS/CSe (together with conventional O- and N-nucleophiles) or CO (together with S- and Se-nucleophiles). As a green approach, the aplication of 3d metals (instead of platinum metals), biomass-based solvents (instead of conventional organic sovents) and CO-surrogates (instead of gaseous C)) is in the forefront of the research activity of the next years.
We plan the synthesis of paramagnetic a-aminophosphonates, P-containing 3,4-disubstituted pyrroline nitroxides. Finding new possibilities of C-C bond forming reactions in the presence of stable nitroxide free radicals, (carbonylation, CH functionalization) is also among our aims. The synthesis and study of new SH-specific spin labels and design of new neuroprotective hybrid molecules and/or theranostic agents are our continuous challenges for a decade.
We also intend to synthesize novel biradical compounds with non-rigid scaffolds and study their spin-spin interactions. We also wish would synthesize paramagnetic pendamethalin derivatives to study the xenobiotic interactions with humic acid/clay models.
The weak interaction between bioactive molecules and their targets is in the focus of of our group. Both the effect of the molecular environment on the interaction between the bioactive molecules and their targets and the interaction of bioactive molecules with the elements of cell membranes are investigated by the highly sensitive photoluminescence studies. The effect of the composition of the solvent mixtures on the stabilities of the cavity-shaped molecules including different cavitand derivatives are planned to study. Molecular vibrations as key molecular motions will be examined in detail to describe its role on the entropy term associated to the molecular interactions.
Either the detection of the enantiomers of methotrexate and other bioactive molecules is planned to be improved due to the analytical purposes.
Further work is planned for studying corrosion properties of 3D printed medical implants made of titanium alloys. Specific interest has been turned up about effects of heat treatment and parameters of printing technology on corrosion resistance and on kinetics of building op passive surface film. Supporting methods as atomic absortion spectroscopy for elementary analysis will be applied as well. (AAS measurements has been carried on in collaboration with geologist and environmental researchers.) In these studies we plan to collaborate with a group of engineering faculty. working together with researchers of the Institute of Biology we are planning to use our recently improved H2S measuring methods in studying whine fermentation processes. A bilateral (Hungary – France) research plan gained support recently. In the framework of it research will be carried on to improve electro-catalytic CO2 method. The new chronopotentiometric antioxidant measuring method recently invented will be further studied studying perspective application fields and finding more stable electro catalyst. The scanning electrochemical microscopy (SECM) method and other applications of chemical an biochemical ultramicro electrodes will go on.
