Synthesis And Coordination Chemistry Of New Oxazoline And Benzoxazole Based Ligands With Lanthanides, Edicome Cornel Shirima
Synthesis And Coordination Chemistry Of New Oxazoline And Benzoxazole Based Ligands With Lanthanides, Edicome Cornel Shirima
Chemistry and Chemical Biology ETDs
In Chapter 1, a brief literature review on the chemistry of lanthanides (Ln) and actinides (An) is described. In addition, the coordination chemistry of lanthanides/actinides with various ligands comprised of organic backbones has also been described. In Chapters 2 and 3 the syntheses of oxazoline and benzoxazole ligands is described. Both ligands contain a hard donor group (P=O) and the nitrogen (N) atom from the heterocycle as a relatively softer donor atom. In Chapter 2 the oxazoline ligand was synthesized in two steps reaction that involves substitution with Ph2P group and oxidation of the phosphine into P=O by air. The …
Isothermal Titration Calorimetry Studies Of Protein-Mediated Interactions And Preliminary Structural Studies Of Tandem Pdz1-2 Domain Of Psd-95 Protein, Ana Jankovic
Wayne State University Dissertations
Protein-mediated interactions that involve multiple ligands in their binding mechanisms are critical for many cellular functions. The primary focus of this dissertation research was to investigate such interactions for two proteins, the PDZ domain and frataxin, involving peptide and metal binding ligands, respectively. The three component projects of this work comprised (1) thermodynamic analysis of PDZ domain binding using calorimetry; (2) X-ray crystallographic structural studies of a PDZ dual domain; and (3) thermodynamic analysis of frataxin binding to iron. The specific goal of the research conducted with the PDZ domains was to understand the mechanism of action of multiple/tandem protein …
