Catalysts play a crucial role in the path towards the transformation of organic compounds. This book describes the recent development of metal-based catalysis in organic synthesis. Applications of various catalysts to interesting organic transformations are discussed. It covers important organic reactions such as cyclohexane oxidation under different energy stimuli, use of Pd-nanoparticles for carbonylation of aniline, ammoximation of methyl ethyl ketone by Ni-modified TS-1 and carbozincation of substituted 2-alkynylamines. This book will be a useful reference for researchers in the field of catalysis, organic chemistry and materials science. It is also intended to attract the attention of researchers with an industrial interest

Cancer is a great challenge to efficient therapy due to biological diversity. Disturbed oxidative homeostasis in cancer cells certainly contributes to differential therapy response. Further, one of the hallmarks of cancer cells is adaptation which includes fine tuning of the cellular metabolic and signalling pathways as well as transcription profiles. There are several factors which contribute to the tumor diversity and therapy response, and oxidative stress is certainly one of them. Changes in oxygen levels due to hypoxia/reoxygenation during tumor growth modulate antioxidative patterns finally supporting increased cell diversity and adaptation to stressing conditions. Additionally, cancer chemotherapy based on ROS production can also induce also adaptation. To counteract these negative effects natural products are often used for their antioxidant activities as well as photodynamic therapy supported by novel chemosensitizers. Understanding of possible pathways which can trigger antioxidant defence at a certain time during cancer development can also provide possible strategies in fighting cancer.

The amide bond represents a privileged motif in chemistry. The recent years have witnessed an explosion of interest in the development of new chemical transformations of amides. These developments cover an impressive range of catalytic N–C bond activation in electrophilic, Lewis acid, radical, and nucleophilic reaction pathways, among other transformations. Equally relevant are structural and theoretical studies that provide the basis for chemoselective manipulation of amidic resonance. This monograph on amide bonds offers a broad survey of recent advances in activation of amides and addresses various approaches in the field.
