Among many research topics, this book considers phytoestrogens, natural compounds found in plants that possess oestrogen-like activity. Despite the growing evidence of the health benefits of phytoestrogens, further investigation is needed to better understand their mechanism of actions, the biological outcomes and possible adverse effects. This book chapter summarises the most recent developments of lanthanide nanorods in the field of biomedical nanotechnology. The cellular uptake of nanoparticles as a function of several parameters, such as polymeric material and surfactant type are considered. Camptothecins (CPTs) are regarded as one of the most promising anticancer drugs of the twenty-first century. A further chapter describes SAR, QSAR, and the clinical chemistry of CPT derivatives to understand their chemical-biological interactions and side effects. This book addresses the biological and pharmacological significances of identification and analysis of effective components of natural medicines and describes methods and procedures for identification and analysis.
