New Excursions Into the Synthesis and Medicinal Chemistry of the Disulfide Bond
摘要:
The presentation discusses two themes of current interest in my research group in conjunction with a garlic mimics program. The first involves a new one-pot methodology for preparing unsymmetrical disulfides in high yield using 1-chlorobenzotriazole (BtCl) as oxidant, which can be applied to a range of functional types. The second part of the lecture will discuss the synthesis of derivatives of the garlic-derived natural product ajoene, in conjunction with an anti-cancer screening program. The synthesis has been used to prepare a fluorescently tagged derivative of the natural product that has been used to investigate localization and mode of action within the cancer cell using confocal laser scanning microscopy.

Fluorine-containing and two-component compositions exhibit improved surface properties for the permanent oil- and water-repellent surface treatment or modification of mineral and non-mineral substrates for various fields of application. At a simultaneously reduced fluorine content, these compositions have considerably improved application properties and, in combination with suitable stabilizing components and hydrophilic silane components, they exhibit excellent hydrophobic, oleophobic and soil-repellent properties, having overall excellent storage stability.

Disclosed is a functionalized polyurethane resin containing a binder component, a hardener component and, optionally, a formulation component. The binder component consists essentially of urethane dispersions with defined structural components which, in turn, consist of special reaction products. Such polyurethane resins are used for the production of fluorine-modified polyurethane coatings and generally in construction or industrial applications for the permanent oil-, water- and dirt-resistant coating of mineral and non-mineral surfaces on the basis of, for example, hydraulically setting components.

Novel fluorine-containing compositions which have improved surface properties for the permanent oil- and water-repellent surface treatment or modification of mineral and nonmineral substrates for various fields of application and are present in single-component form are claimed. These compositions have, at a reduced fluorine content, significantly improved use properties and they can, in combination with suitable stabilizing components and hydrophilic silane components, be additionally optimized in terms of their hydrophobic, oleophobic and dirt-repellent properties, and they have excellent storage stability.
