QSAR studies on Topoisomerase-II inhibitors, Sharma Meenakshi

The objective of drug discovery phase is to synthesize lead compounds, new analogs with improved potency, reduced off target activities, and physiochemical/metabolic properties suggestive of reasonable in vivo pharmacokinetics. This optimization is accomplished through empirical modification of the hit structure and/or by employing structure-based design if structural information about the target is available. The goal of present work is to design drug with minimum side effect and maximum potency. 2D QSAR is planned using Multiple Linear Regression Analysis ... więcej

?-Glucane aus Eumycota, Nitschke Jörg

β-Glucane, hochmolekulare Polysaccharide, aus Basidiomycetes und Ascomycetes sind bekannt für ihre Wirkung als „Biological Response Modifier" und als antikanzerogene Substanzen. Aktuell angewandte Extraktionsmethoden führen zu einer partiellen Degradation der nativen Struktur. Ein alternativer Extraktionsprozess für diese Glucane ist deswegen von besonderem Interesse. Im Rahmen dieser Dissertation wurde eine enzymatische Extraktionsmethode entwickelt. Dabei konnte ein Prozess realisiert werden, der in Kombination von enzymatischen ... więcej
