Macromolecular Anticancer Therapeutics (eBook, PDF)

• Format: PDF

Produktbeschreibung

The field of macromolecular therapeutics for cancer therapy is of considerable importance, as these therapeutic systems are gaining more and more interest to give new directions for the treatment of this dreadful disease. Macromolecular Anticancer Therapeutics, which describes in detail the macromolecular therapeutics for cancer therapy, covers the classification of these anticancer drugs based on therapeutic targets, and elaborates on different classes of anticancer therapeutics which are either in pre-clinic or in clinical phases or are already commercialized. This book also discusses various signal transduction pathways involved in the cancer growth and resistance to therapy, providing a clear insight into the molecular mechanistic aspects of this topic; it also describes the essential targets for efficient cancer therapy. In detail, this volume elaborates the different categories of macromolecular therapeutics of respectively natural and synthetic polymer and lipid origin, their chemistry, design and development, opportunities and challenges, current status, pre-clinic and clinical progresses. In addition, the design, development, and the challenges involved in future directions for cancer therapy using various categories of antibody-based therapeutics are elaborated in areas such as antibody-mediated drug targeting to cancer employing antibody-drug conjugates, radioimmunoconjugates, toxin-antibody conjugates, antibody-mediated enzyme pro-drug therapeutics, and also using antibodies alone to interfere with specific molecular targets responsible for tumor growth and progression. Besides the current status, pre-clinic and clinical progress of a variety of therapeutic anticancer oligonucleotides and siRNA designed and developed for specific inhibition of oncogenes are detailed. Furthermore, in this book, special attention is given to the treatment of breast cancer based on a comprehensive description about molecular mechanisms involved, hormone receptors implicated and molecular therapeutic interventions.

Macromolecular Anticancer Therapeutics details the current macromolecular therapeutic strategies, and should become an important reference for practitioners, oncologists, medical pharmacologists, medicinal chemists, biomedical scientists, experimental pharmacologists and pharmaceutical technologists. It is also a reference concerning macromolecular cancer therapy for graduates, post-graduates and Ph.D. students belonging to these fields.

Autorenporträt

L. Harivardhan Reddy is Head of Nanovectors group at Sanofi-aventis, France. He completed Ph.D. in Pharmaceutics and Drug delivery in 2005 from The M.S. University of Baroda, India. He has worked for 4 years in two popular pharmaceutical companies (Sun Pharmaceutical Industries Ltd., and Aristo Pharmaceuticals Ltd.) in India, on drug delivery applications. He worked for 3 years (2005-2008) with anticancer drug delivery specialist Prof. Patrick Couvreur in CNRS lab at Université Paris-Sud, Chatenay-Malabry, France. He is an inventor of 3 patents belonging to macromolecular therapeutics and drug delivery. He has published, as an author and co-author, more than 60 publications in various reputed journals. He is also a reviewer for more than 15 journals of the fields of biomacromolecules, drug delivery, cancer therapy, and pharmacology. He is a member of The European Association for Cancer Research. His principal research interests are supramolecular lipidic prodrug nanomedicines and nanotherapeutics for cancer.   Patrick Couvreur is a Full Professor of Pharmacy at the University Paris-Sud, France, and holder of the chair of "Innovation Technologique" (2009-2010) at the prestigious 'Collège de France'. He is a member of the Academy of Technologies (France), of the Academy of Pharmacy (France) and corresponding member of the Royal Academy of Medicine (Belgium). Prof. Patrick COUVREUR's contributions in the field of drug delivery and targeting are highly recognized and respected around the world. Patrick COUVREUR performed a pioneer work together with Peter SPEISER, and demonstrated for the first time in 1977 that nanoparticles may be used as intracellular carriers for compounds which don't diffuse spontaneously into cells. Patrick COUVREUR's research is primarily on polymer-based and metallic-based nanomedicines, surface engineered nanosystems, and also focuses on lipid-based nanocarriers. He has publishedas an author and co-author, 341 publications, 109 review articles and book chapters, 6 books as editor, 50 patents, and 193 invited and plenary lectures at national and international congresses. He has received Pharmaceutical Sciences World Congress Award (2004), the "Marie-Maurice Janot Lecture" (2008) and above all the prestigious "Host Madsen Medal" (2007) in honour of his outstanding research achievements. He is a Field Editor of "Pharmaceutical Research", European Editor of the "Journal of Nanoparticles Research", and is a reviewer of more than 15 high reputed journals in the fields of Drug delivery, cancer research, macromolecules, physical chemistry etc. He is acting or acted as Board of Governors of the Controlled Release Society (CRS), Board of APGI, Expert Member of the Board of Pharmaceutical Sciences, International Pharmaceutical Federation (FIP). His exceptional research has led to two start-up companies BIOALLIANCE and MEDSQUAL dealing with novel therapeutics, in France.
