Book Description
Protease inhibitors (PIs) are widely distributed in plants and animals, and have a variety of functions, which include preventing digestion of seeds by insects and modifying blood clotting in animals. After it was noted that synthetic and natural inhibitors suppress two-stage carcinogenesis and breast cancer, extensive work investigating PIs as chemopreventive agents was started. PIs are unique in that they interfere with cancer development in a variety of ways, including suppression of oxygen radicals, oncogenes, and metastases. Epidemiologic evidence supports their prevention of major human cancers in populations that consume foods containing them. Their supervised use in humans is on the threshold of development. The epidemiologic discovery of the importance of lentils and other seeds rich in PIs in preventing many human cancers allowed us to look at the action of PIs as chemopreventive agents, as reviewed in Chapter I (Fontham and Correa). Chapter 2 (Kennedy) discusses the role of natural PIs (e. g. , the Bowman-Birk inhibitor) as anticarcinogens and the possible limitations of their use. In Chapter 3 (Kennedy), the transformation of C3HI lOTlh cells caused by carcinogens and promoters is shown to be suppressed by PIs. Bowman (Chapter 4) relates the discovery of inhibitors in soybeans that are distinct from the Kunitz inhibitor, and the occurrence of a similar inhibitor in peanuts and other legumes. Chapter 5 (Birk) is an overview of PIs of plant origin and their role in human nutrition.

Book Description
The ultimate goal of cancer chemoprevention research and development is the identification of pharmaceutical or dietary constituents that will prevent cancer. Cancer Chemoprevention presents the proceedings of a large workshop on cancer chemoprevention that highlights the latest knowledge in the field, in addition to issues and ideas concerning future directions. Retinoids, sulfur compounds, and a large number of many naturally occurring cancer inhibitors in the diet are discussed, including green tea, garlic constituents, citrus fruit oils, and beans and seeds containing protease inhibitors. Compounds that may prevent the formation of carcinogens in food are covered, and the mechanisms by which chemical or dietary agencts produce cancer inhibitors are discussed.

Book Description
Phytochemicals from medicinal plants are receiving ever greater attention in the scientific literature, in medicine, and in the world economy in general. For example, the global value of plant-derived pharmaceuticals will reach $500 billion in the year 2000 in the OECD countries. In the developing countries, over-the-counter remedies and "ethical phytomedicines," which are standardized toxicologically and clinically defined crude drugs, are seen as a promising low cost alternatives in primary health care. The field also has benefited greatly in recent years from the interaction of the study of traditional ethnobotanical knowledge and the application of modem phytochemical analysis and biological activity studies to medicinal plants. The papers on this topic assembled in the present volume were presented at the annual meeting of the Phytochemical Society of North America, held in Mexico City, August 15-19, 1994. This meeting location was chosen at the time of entry of Mexico into the North American Free Trade Agreement as another way to celebrate the closer ties between Mexico, the United States, and Canada. The meeting site was the historic Calinda Geneve Hotel in Mexico City, a most appropriate site to host a group of phytochemists, since it was the address of Russel Marker. Marker lived at the hotel, and his famous papers on steroidal saponins from Dioscorea composita, which launched the birth control pill, bear the address of the hotel.

Cutting-edge investigators review the current status of the entire field, from the biology of MMPs through the current clinical studies. The authors include many leading scientists from pharmaceutical companies who present all the latest concepts and results on the preferred design strategies for MMP inhibitors, their molecular mechanisms, and their substrates. In addition, they fully describe their personal research on specific MMP inhibitors, detailing vanguard design strategies, their in vitro activity, the outcome of animal model studies and, where available, their toxicology, safety, efficacy in human clinical trials. Comprehensive and state-of-the-art, Matrix Metalloproteinase Inhibitors in Cancer Therapy offers basic and clinical investigators alike a richly informative summary of all the latest research on these powerful new drugs, and their high promise as emerging cancer therapeutics.

Book Description
Toxic Constituents of Plant Foodstuffs focuses on toxic substances in foods of plant origin, including protease inhibitors, hemagglutinins, goitrogens, cyanogens, saponins, gossypol, lathyrogens, and allergens. The book also considers adventitious toxic factors in processed foods and miscellaneous toxic factors such as stimulants and depressants, hypoglycemic agents, toxic amino acids, metal-binding constituents, and hepatotoxins. This volume is organized into 13 chapters and begins with an overview of protease inhibitors, including their distribution in the plant kingdom, physical and chemical properties, and mechanism of interaction with proteases. The next chapters focus on the adventitious introduction of toxic factors into processed plant foods; the inactivation of the trypsin inhibitor and hemagglutinin found in legumes by cooking; and the extraction of a nontoxic, edible starch from cycads. The reader is also introduced to lathyrism, the toxicity of agglutinins, occurrence of goitrogens in thioglucoside-containing plants, and dietary sources of cyanogen. This book will be of interest and value to food scientists who are concerned with the safety of food supply and public health officials tasked with enforcing regulations necessary to ensure the safety of a particular food.
