摘要:

AbstractViewed globally, parasitic diseases such as malaria and Chagas' cardiopathy pose an increasing threat to human health and welfare. Recognition of this problem and the challenge of synthesizing a quinine‐like antimalarial agent sparked off the development of the chemical industry about 100 years ago. Our contribution deals with aspects of drug design, a young branch of pharmaceutical chemistry. As drug targets the flavoenzyme, glutathione reductase, and the recently discovered parasite enzyme, trypanothione reductase, were chosen. Based on the knowledge of the structure of these molecules, the modeling of enzyme inhibitors as potential chemotherapeutic agents against parasites has become possible. In addition, biochemical and clinical observations are considered since chemical principles of biological evolution can serve as guidelines for the pharmaceutical chemists. The picture shows two erythrocytes destroyed by malaria parasites. In the center of the photograph a parasite is just leaving its host cell through the ruptured cell membrane. Its target could be a neighboring healthy erythrocyt

摘要:

AbstractThe design, synthesis, characterization, and understanding of new molecular and macromolecular assemblies with large macroscopic optical nonlinearities represents an active field of research at the interface of modern chemistry, physics, and materials science. Challenges in this area of photonic materials typify an important theme in contemporary chemistry: to create new types of functional materials by the rational construction of supramolecular assemblies exhibiting preordained collective phenomena by virtue of “engineered” molecule–molecule interactions and spatial relationships. This review surveys several approaches to, and the microstructural and optical properties of, second‐order nonlinear optical materials built from noncentrosymmetric assemblies of chromophores having large molecular hyperpolarizabilities. Such types of materials can efficiently double the frequency of incident light, exhibit other second‐order nonlinear optical effects, and contribute to the knowledge base needed for new photonic device technologies. Systems described include chromophore macromolecule guesthost matrices, chromophore‐functionalized glassy macromolecules, thermally crosslinked chromophore‐macromolecule matrices, and intrinsically acentric self‐assembled chromophori
