Natural Products have been important sources of useful drugs from
prehistoric times to the present. This book is reviewing reviews and discusses some important recent contributions to the discovery of new drugs generated by research on natural products. Total synthesis of natural products with interesting
biological activities is paving the way for the preparation of new and improved analogs. The methods of combinatorial chemistry permit the selection of the best drug from a large number of candidates. Beyond synthesis and evaluation of organic molecules a number of new
bioorganic methods are coming to the fore.
