Razoxane and dexrazoxane are two novel drugs with some uniquely useful features. They block cell division at the G2/M border, but nowhere else, so that they have a low toxicity profile. They suppress tumor metastasis and haemorrhages through normalization of pathological blood vessels. Razoxane potentiates radiotherapy especially in the treatment of soft tissue sarcomas and gastrointestinal neoplasms. They protect normal tissues against toxic chemicals, e.g. the myocardium against anthracyclines or subcutaneous tissue against injuries caused by incidental extravasations of anthracyclines. Dexrazoxane is the only drug approved by the FDA/EMEA for the specific purpose of preventing cardiac damage when giving the widely used and effective antitumor anthracyclines. The reduction of cardiotoxicity is achieved without response reduction or reducing of time to progression of tumors. While the full analysis of their actions at the molecular level is not yet completely understood, it seems most likely that it is via an inhibition on the topoisomerase II a. Moreover, the drugs have the ability to chelate several metals including iron, copper or zinc. The protection of normal tissues is nowhere more important than that of brain, and there are indications that the proteins thought to be responsible for the ravages of Alzheimer ́s disease could be stabilized by one or both these drugs.

Some drugs which are not aimed at treating heart disease have nevertheless been found to have profound effects on heart muscle. Cardiotoxicity is one of the major forms of toxicity seen in drugs and it accounts for most drug recalls and delays experienced in regulatory approvals.In recent years a number of non-cardiac blockbuster drugs such as terfenadine have been withdrawn from major markets because of cardiotoxicity concerns, while other drugs have either been withdrawn prior to marketing or required labelling changes that significantly restricted their use. In Cardiotoxicity of Non-Cardiovascular Drugs international experts describe the molecular mechanisms and clinical read-outs of cardiac events induced by a broad variety of noncardiovascular drugs. Particular emphasis is paid to the preclinical screening of drug cardiotoxicity. Topics include: metabolic targets of cardiotoxicity regulatory aspects translating molecular mechanisms into clinical trials structure-activity relationships in arrhythmias by antihistamines and psychoactive drugs cardiovascular toxicity of antitumor drugs cardiovascular toxicities of non-steroidal anti-inflammatory drugs cardiovascular toxicities of antiretroviral therapies Cardiotoxicity of Non-Cardiovascular Drugs is an essential guide to this important area of drug development. It will find a place on the bookshelves of researchers, regulators and students in medicinal chemistry, drug development, pharmacology, pharmacy and cardiovascular disease.

DNA topoisomerases represent an essential family of DNA processing enzymes and a large number of topoisomerase inhibitors are used clinically for the treatment of various human cancers. Novels drugs are in clinical development both against type I and type II topoisomerases. The book will include basic biochemical and structural reviews for the cancer-relevant topoisomerases. It will describe how topoisomerase dysfunctions can damage the genome and increase the risk of cancers, and the involvement of topoisomerases in programmed cell death. The book will also present the various topoisomerase inhibitors in clinical use and development and their molecular and cellular mechanisms of action.

The first book focusing specifically on frequent and frequently disabling side effects involving the skin, hair and nails in cancer patients According to the World Health Organization, there are approximately thirty million people living with a diagnosis of cancer – the majority of whom will receive surgery, systemic therapy, and/or radiation, and who will suffer from dermatologic adverse events. Dermatologists and oncologists are only beginning to grapple with these events, which pose serious quality-of-life issues with so many patients, and will become more prevalent as survival rates improve, thanks in part to new cancer treatments and drug regimens. Concentrating on a topic that has only been briefly touched upon by other texts, this book offers a focused perspective on the clinical presentation, underlying pathophysiologic mechanisms, and management of skin, hair, and nail conditions for oncologists, dermatologists, and allied practitioners. Dermatologic Principles and Practice in Oncology: Conditions of the Skin, Hair, and Nails in Cancer Patients: • Covers in detail the dermatologic adverse events of oncologic therapies, clinical presentations, and treatment recommendations • Enables dermatologists and other practitioners to significantly improve the care of patients with cancer • Addresses the dermatologic adverse events of cancer therapies used globally, of which a large number are found in developing countries • Emphasizes prophylactic measures – based on treatments used and type of cancer – to prevent the appearance of adverse events • Provides built-in discussions on patient education for practical counseling during therapies • Offers rapid-reference sections on topical dermatology drugs The first book to present dermatologic conditions in cancer patients and survivors in a uniform and in-depth manner, Dermatologic Principles and Practice in Oncology is ideal for oncologists, oncology nurses, and dermatologists who wish to take better care of those with adverse skin, hair, and nail conditions.

The book begins with the basic science behind the medical applications of the knowledge: cardiovascular biology, pathways, and their relationship to cancer treatment and principles of chemotherapy and immunotherapy. The second section consists of an overview and classification of anti-cancer drugs and a look at their cardiotoxicity. The third section looks at cardiac imaging in the cancer patient, including cardiac ultrasound, Doppler imaging, nuclear imaging, magnetic resonance imaging, and computed tomography in the cancer patient. In section four, management of cardiac disease in the cancer patient is discussed, including cardiac rhythm disturbances and heart failure. Cardiac emergencies and interventions are described as is preoperative assessment of the cancer patient for non- cardiovascular surgery. The final section includes a range of topics such as the pericardium, cardiovascular effects of endocrine treatments, primary cardiac tumors and malignancies of the myocardium and pericardium. Cardiac monitoring during clinical trials and pulmonary concerns are also addressed, as are psychosocial, social, economic, and legal issues of the cancer patient with heart disease.

Collectively, neurodegenerative diseases are characterized by chronic and progressive loss of neurons in discrete areas of the brain, producing debilitating symptoms such as dementia, loss of memory, loss of sensory or motor capability, decreased overall quality of life eventually leading to premature death. Two types of cell death are known to occur during neurodegeneration: (a) apoptosis and (b) necrosis. The necrosis is characterized by the passive cell swelling, intense mitochondrial damage with rapid loss of ATP, alterations in neural membrane permeability, high calcium influx, and disruption of ion homeostasis. This type of cell death leads to membrane lysis and release of intracellular components that induce inflammatory reactions. Necrotic cell death normally occurs at the core of injury site. In contrast, apoptosis is an active process in which caspases (a group of endoproteases with specificity for aspartate residues in protein) are stimulated. Apoptotic cell death is accompanied by cell shrinkage, dynamic membrane blebbing, chromatin condensation, DNA laddering, loss of phospholipids asymmetry, low ATP levels, and mild calcium overload. This type of cell death normally occurs in penumbral region at the ischemic injury site and in different regions in various neurodegenerative diseases.

The Fifth International Meeting on Cholinesterases convened in Madras, India, in September of 1994. The long and rich history and culture of India provided an excellent setting for the meeting. More than 120 delegates from Asia, Australia, Europe and North America heard 54 oral presentations and viewed 54 posters on current research on enzymes of the cholinesterase family. The aim of this book is to compile the presentations of the Fifth International Meeting on Cholinesterases into a volume that describes recent investigations on the structure and catalytic function of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and related enzymes, as well as studies on the molecular and cellular biology of these enzymes and the genes which encode them. Cholinesterases enjoy a long and storied history in diverse areas. In basic biochemical research, AChE is one of the best studied, though yet enigmatic, of enzymes. The efficient catalytic function of this enzyme presents the biochemist with a fundamental challenge in understanding the relationship between structure and function. AChE and BuChE belong to a family of proteins, the alB hydrolase fold family, whose constituents evolutionarily diverged from a common ancestor. Proteins in this family have a wide range of physiological functions. In commerce, AChE is a prime target for agricultural insect control, and for the development of therapeutic agents for Alzheimer's disease.
