'Light' from low level laser therapy, through a process called
photobiomodulation (PBM), has been in existence in supportive care
in cancer, in particular in the management of oral mucositis (OM)
in patients undergoing chemotherapy, radiation therapy and
haematopoietic stem cell transplantation. In this book the authors
attempt to portray the current status of the supportive care
interventions that are possible with PBM using low level laser
therapy (LLLT) in patients undergoing cancer treatment for solid
tumours, harmatological malignancies, and head and neck cancers.
The discovery of the anti-tumour activity of cisplatin in 1965, and
its subsequent introduction into clinical trials in 1971, was the
catalyst for a major research effort into the potential of metal
compounds in cancer therapy. This book provides a discussion of
metal compounds in cancer therapy. This book should be of interest
to research workers in the pharmaceutical industry, particularly
tumour pharmacologists, tumour biologists, medicinal chemists and
oncologists.
This book will be a guide to understanding resistance against
targeted therapeutic approaches for cancer using immunotoxins. It
contains a detailed review of the history and development of
targeted therapy. As well, it includes an in-depth description of
the molecular and cellular mechanisms involved in cancer resistance
and several novel methods to overcome resistance. Each chapter
discusses different aspects of resistance and covers all the
factors that may contribute to resistance in cancer cells. Finally,
this volume highlights the recent findings and advances associated
with tackling cancer resistance.
One of the most important developments in the field of
cardiovascular medicine over the last two decades has been
recognition of the key role played by arterial thrombosis in the
pathogenesis of acute coronary syndromes, ischemic complications of
percutane- ous coronary revascularization, and coronary and
peripheral atherosclerosis. The phar- macologic armamentarium
directed against vascular thrombosis has thus expanded
substantially during that time, with development of new
fibrinolytic agents, low-molecu- lar-weight heparins, direct
thrombin inhibitors, antagonists to platelet activation, and the
platelet glycoprotein lIb/IlIa inhibitors. Though clinical
investigations of these com- pounds have been marked by failures as
well as successes, there is little doubt that enhanced
antithrombotic therapies have markedly improved the outcome of
patients undergoing coronary revascularization or with acute
coronary syndromes. Glycoprotein IIblIlIa receptor antagonists were
introduced into clinical practice to overcome the limitations of
approaches that inhibit only individual pathways of platelet
activation. Multiple mechanisms of platelet activation in response
to different agonists converge on the platelet membrane
glycoprotein IIblIlIa complex, the "final common pathway" of
platelet aggregation. The clinical hemorrhagic syndrome caused by a
rare inherited defect in this receptor (Glanzmann' s
thrombasthenia), characterized by muco- cutaneous and postsurgical
bleeding, but infrequent spontaneous organ (particularly central
nervous system) bleeding, suggested that therapeutic inhibition of
this receptor might be a potent, yet well-tolerated means of
treating thrombotic disorders.
Antifolates are an important class of anticancer drugs originally
developed as anti leu- kemic agents, but now used, usually in
combination with other drugs, for the treatment of a wide range of
tumors, notably carcinomas of the head and neck, breast, germ cell
tumors, non-Hodgkin's lymphoma, acute lymphoblastic leukemia, and
osteogenic sar- comas. 5-Fluorouracil and its prodrugs also target,
in part, the folate-dependent enzyme, thymidylate synthase.
Furthermore, folate supplementation in the form of leucovorin,
modulates 5-fluororuacil activity. 5-Fluorouracil is widely used in
the treatment of colorectal and gastric cancer and in combination
for other solid tumors such as breast and head and neck cancers.
Ongoing clinical trials with the newer antifolates suggest that the
range of solid tumors where these agents will be of use may broaden
further. Half a century ago, interesting scientific and clinical
discoveries suggested that folie acid was a vitamin involved in
vital cellular metabolic processes. The folate analogs, aminopterin
and methotrexate, were synthesized by the American Cyanamid Company
in an attempt to interfere with these processes and were shown to
have anticancer activity by Farber and his colleagues. Hence, the
principle of antimetabolite therapy for the treatment of cancer was
established. Biomedical research over the following years led to a
deeper understanding of the complex biochemical pharmacology of
folates and antifolates. Selective antimicrobial agents were
discovered, but more tumor-selective anticancer agents did not
immediately emerge.
Antibody-directed enzyme prodrug therapy (ADEPT) directly addresses
the major problem in cancer chemotherapy-its lack of selectivity.
Antibody delivery combined with the amplification provided by the
enzymatic activation of prodrugs enables selection to be made
between tumour and normal tissue. ADEPT offers a novel field of
opportunities in the therapy of systemic cancer and may be a major
advance for the treatment of solid tumours. This book is the first
to describe ADEPT in detail. Each chapter reviews an aspect of the
immunology, enzymology, biochemistry, chemistry, and cancer
chemotherapy which have been integrated into the ADEPT concept. An
additional chapter describes the related approach of gene-directed
enzyme prodrug therapy (GDEPT). This latter approach is still in
its infancy but ADEPT has entered the clinic. The initial clinical
studies with ADEPT are included and discussed in detail.
Biological inorganic chemistry is a field of research at the interface of inorganic and biological chemistry. The rapidly developing insights into the role of metals in biological systems has far-reaching implications not only for biological science but also for related disciplines, ranging from molecular medicine to the environment. In each volume the reader, whether engaged in chemistry, biochemistry, biology or molecular medicine, receives a comprehensive summary and critical overview of a topic of high current interest written by leading international experts.
In 1971, J. Folkman published in the New England Journal of
Medicine a hypothesis that tumor growth is angiogenesis-dependent.
Folkman introduced the concept that tumors probably secrete
diffusible molecules that could stimulate the growth of new blood
vessels toward the tumor and that the resulting tumor
neovascularization could conceivably be prevented or interrupted by
angiogenesis inhibitors. Solid and haematological tumors consist of
an avascular and a subsequent vascular phase. Assuming that this
depends on the release of angiogenic factors, acquisition of
angiogenic capability can be seen as an expression of progression
from neoplastic transformation to tumor growth and metastasis.
Beginning in the 1980 s, the biopharmaceutical industry began
exploiting the field of antiangiogenesis for creating new
therapeutic compounds for modulating new blood vessels in tumor
growth. In 2004, Avastin (Bevacizumab), a humanized anti-VEGF
monoclonal antibody, was the first angiogenesis inhibitor approved
by the Food and Drug Administration for the treatment of colorectal
cancer. At present, it has been estimated that over 20,000 cancer
patients worldwide have received experimental form of
antiangiogenic therapy.
This book offers a historical account of the relevant
literature. It also emphasizes the crucial and paradigmatic role of
angiogenesis as a biological process and the significance of
antiangiogenic approach for the treatment of tumors."
The 7th International Symposium on Platinum and other metal
coordination compounds in Cancer Chemotherapy, ISPCC '95, organized
by the European Cancer Centre, was held in Amsterdam, the
Netherlands, March 1-4, 1995. As with previous ISPCC meetings, the
goal of ISPCC '95 was to bring together c1inicians, clinical
investigators, scientists, and laboratory workers from many
disciplines to promote further collaboration and cooperation in the
development of new platinum and other metal coordination compounds
as weil as in new ways to use 'c1assical' drugs as cisplatin and
carboplatin in the treatment of cancer. Important aspects addressed
by experts in the field inc1uded the synthesis and activity of new
platinum compounds, the biochemistry and molecular pharrnacology as
weil as the c1inical pharrnacology of this c1ass of antineoplastic
agents, an overview of current c1inical studies, one special
minisymposium on the mechanisms of cell kill of platinum, and one
on resistance against platinum compounds. Finally, the current
status of development of nonplatinum metal complexes was discussed.
This volume contains the contributions of the various speakers at
ISPCC '95 and provides an up-to-date and comprehensive overview of
this important c1ass of anticancer agents, ranging from synthesis
and molecular pharrnacology on one hand to c1inical pharrnacology
and cIinical investigations on the other hand. The Organizing
Corrunittee and Editors wish to express their gratitude to the
contributors to this volume, to the various organizations and
pharrnaceutical companies for their generous sponsoring of ISPCC
'95, and to the Plenum Publishing Company for their help in
producing this volume.
The last decade has seen a renaissance of the concept of individualized chemotherapy in oncology, markedly stimulated by the development of new in vitro chemosensitivity assays. The clinical utility of drug response assays has been evaluated in clinical trials and the results suggest that assay-assisted therapy selection may improve survival as well as economic outcomes. This volume comprises the proceedings of the first Symposium of the International Society for Chemosensitivity Testing in Oncology, ISCO-1, held in Homburg/Saar, Germany, in September 2001. The topics include: new in vitro drug-testing methods, tumor chemosensitivity assays, and the clinical relevance of assay-directed therapy.
Antibody-drug conjugates (ADCs) represent a promising therapeutic
approach for cancer patients by combining the antigen-targeting
specificity of monoclonal antibodies (mAbs) with the cytotoxic
potency of chemotherapeutic drugs. In Antibody-Drug Conjugates,
expert researchers provide detailed protocols for many of the key
ADC techniques necessary for working in the field. These chapters
and methodologies are aimed at the key tasks necessary to identify
a suitable target, properly design the mAb, the linker and the
payload, as well as to conjugate them in a reproducible and
scalable fashion. Written in the highly successful Methods in
Molecular Biology (TM) format, these detailed chapters include the
kind of practical implementation advice that guarantees quality
results. Authoritative and timely, Antibody-Drug Conjugates aims to
further drive ADC development and thus help toward improving cancer
treatments of the future.
Philip Rosenthal, MD, and a panel of leading malaria experts drawn
from academia, the military, and international health organizations
survey the latest scientific understanding of antimalarial
chemotherapy, emphasizing the molecular mechanisms of resistance
and the description of important new targets. Their survey covers
the current status of malarial and antimalarial chemotherapy, the
relevant biology and biochemistry of malaria parasites, the
antimalarial drugs currently available, new chemical approaches to
chemotherapy, and possible new targets for chemotherapy.
Comprehensive and cutting-edge, Antimalarial Chemotherapy:
Mechanisms of Action, Resistance, and New Directions in Drug
Discovery clearly delineates all the basic and clinical research
now addressing one of the world's major unresolved disease
problems, work that is now powerfully driving the rapid pace of
antimalarial drug discovery today.
Resistance to chemotherapy, and especially multi-drug resistance,
represents a significant barrier to the successful treatment of
cancer. This multi-author volume brings together a wide range of
up-to-date reviews on different aspects of our knowledge of
drug-resistance mechanisms, written by experts in the different
areas. Particular attention is paid to recently discovered
mechanisms relating to oncogene expression and in particular to
proteins involved in regulation and execution of apoptosis. Other
important topics covered include DNA repair, topoisomerases, cell
cycle control, oxygenation and vascularisation of tumours, LRP,
intermediate filament proteins and low-level resistance. Recent
developments in understanding the role of efflux pumps (P-170, MRP)
in multi-drug resistance are also reviewed. This book will be
useful to clinicians and scientists working in the areas of
chemotherapy, drug resistance, DNA repair and apoptosis research.
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.
This interdisciplinary volume collates research work on kinesins
and cancer. Authors attempt to validate members of the kinesin
superfamily as potential targets for drug development in cancer
chemotherapy. The work begins by highlighting the importance of
kinesins, summarising current knowledge and how they are shown to
be crucial for mitosis. Chapters go on to explore how this family
of proteins are emerging as a novel target for chemotherapeutic
intervention and drug development. Readers will learn how kinesins
travel along microtubules to fulfill their many roles in
intracellular transport or cell division. Several compounds that
inhibit two mitotic kinesins (called Eg5 and CENP-E) have entered
Phase I and II clinical trials and are explored in these chapters.
Additional mitotic kinesins are currently being validated as drug
targets, raising the possibility that the repertoire of
kinesin-based drug targets may expand in the future. The book is
suitable as a reference standard for the field of kinesins and
cancer. It will interest those in academia and pharmaceutical
companies, and anyone with an interest in the medical relevance of
these proteins, which cutting edge methodologies are now enabling
us to understand in astonishing detail.
Great advances were made in the pharmacologic-based treatment of
cancer in prior decades. However, despite a marked increase in our
understanding ofcell and molecular mechanisms underlying the
neoplastic process, therapy for advanced disease remains limited.
While the reasons for this are many, it is generally accepted that
advanced neoplasms contain a relatively large number of genetic and
molecularalterations contributingto the maintenanceofthe neoplastic
process. Such a situation precludes easy pharmacologic
intervention. However, our ability to detect cancer at an earlier
stage, coupled with our increased understandingofcarcinogenesis,
are propellingboth basic and clinical scientiststo pursue early
intervention/chemopreventive approaches. This is based upon the
notion that fewer molecularaberrations are presentearlyon
inthedisease process. It also takes advantage ofthe fact that
advances in both technology, and in the field ofcancer biology,
coupled with a heightened vigilance, have increased our ability to
detect early disease more readily. The chemopreventive approach is
highly attractive for a number ofreasons. First, treatment
ofpre-neoplastic, or early neoplastic, lesions would prevent the
significant mobility and mortality associated with advanced
neoplastic disorders.
The title of this monograph, Brain Tumor Research and Therapy, is
the name of the Conference itself, which had its inaugural meeting
in the United States in 1975 andhas since progressed to the
international scale. In Japan, the first conference ofits kind was
organized by Dr. Takao Hoshino and me and was held at Nikko in
1980, hence its name, the Nikko Conference on Brain Tumor Research
and Therapy. Though it started as a small, closed meeting, the
conference has grown considerably, and in 1992 it was reorganized
as the Japanese Conference on Brain Tumor Research and Therapy and
was opened to all neurosurgeons and neuropathologists interested in
the study of brain tumor problems and who are participating in this
field. The main purpose of the Conference on Brain Tumor Research
and Therapy is the candid and informed discussion of the most
up-to-date developments in basic re search and clinical treatment
of brain tumors. The 3rd Japanese Conference on Brain Tumor
Research and Therapy was held at Nasu (Tochigi Prefecture), Japan,
in No vember 1994. It was a great honor to welcome many
distinguished guests from over seas who kindly attended each
session and made valuable contributions.
This book presents a comprehensive collection of essential and
up-to-date methods for studying both the biology of microtubules
and the mechanisms of action of microtubule-interacting drugs. The
book contains a straightforward presentation of readily
reproducible protocols, tips for troubleshooting, and advice on
avoiding common mistakes. Basic scientists and clinical researchers
will benefit from this collection.
Cancer drug discovery has been and continues to be a process of
ingenuity, serendip ity, and dogged determination. In an effort to
develop and discover better therapies against cancer, investigators
all over the world have increased our knowledge of cell biology,
biochemistry, and molecular biology. The goal has been to define
therapeuti cally exploitable differences between normal and
malignant cells. The result has been an increased understanding of
cellular and whole-organism biology and an increased respect for
the flexibility and resiliency ofbiologically systems. Thus, as
some new therapeutic targets have been defined and new therapeutic
strategies have been attempted, so have some new biological hurdles
resulting from tumor evasion of the intended therapeutic attack
been discovered. Historically, anticancer drugs have originated
from all available chemical sources. Synthetic molecules from the
chemical industry, especially dyestuffs and warfare agents, and
natural products from plants, microbes, and fungi have all been
potential sources of pharmaceuticals, including anticancer agents.
There is no shortage of molecules; the challenge has been and
continues to be methods of identifying molecules that have the
potential to be therapeutically important in human malignant
disease. "Screening" remains the most important and most
controversial method in cancer drug discovery. In vitro screens
have generally focused on cytotoxicity and have identified several
highly cytotoxic molecules. Other endpoints available in vitro are
inhibition of proliferation, 3 inhibition of [ H]thymidine
incorporation into DNA and various viability assays, based most
frequently on dye exclusion or metabolism.
