Book Description
This Research Topic is part of a series with: Multi-targeted Natural Products as Cancer Therapeutics: Challenges and Opportunities, Volume II Cancer remains a leading cause of disease-related deaths worldwide, despite recent advances in our understanding of cancer initiation, progression, and metastasis. Chemotherapy and radiotherapy have been used as standard non-surgical treatments of human cancer for decades, however, the survival rates of patients with cancer, especially those with advanced diseases are still very low due to the high toxicities of these treatments as well as the severe side effects. This fact has motivated researchers to discover new cancer therapeutics with minimum side effects, which intensively promotes the rapid development of single specific molecule-targeted therapies (SSMTT). Many efforts have been made in world-wide cancer drug discovery research and several single molecule-targeted therapies have been successfully developed. Unfortunately, most of the investments failed because cancer is a genetic disease and always harbors multiple alternations of molecules or genes at the genomic, genetic and epigenetic levels. The inhibition of a single molecule or signaling pathway by SSMTT frequently results in a hyperactive compensation of other cancer-related molecules and signaling pathways as well as the subsequent development of drug resistance. Therefore, identifying multi-targeted therapies, i.e. drugs that are able to target multiple cancer-related genes, proteins, or signaling pathways is a more promising way to success in developing new cancer therapeutics. Natural products, especially those from traditional Chinese medicine and folk remedies in other countries are an extraordinarily important source for new drug discovery over the past decades. Of note, many natural products have often been demonstrated to target several crucial genes or proteins in cancer-related signaling networks and exert synergistic effects. For example, Japonicone A, a dimeric sesquiterpenoid from the medicinal plant Inula japonica, has been found to inhibit tumor growth and metastasis by dually targeting the TNF-α/NF-κB and p53/MDM2 signaling pathways. Traditionally, researchers have believed that the multi-targeting mechanisms of natural products have limited their use in cancer treatment due to the low specificity and potential side effects. The growing interest in developing multi-targeted cancer therapies may provide another golden opportunity to develop natural products as new cancer therapeutics. Nevertheless, critical investigations for a comprehensive understanding of the molecular mechanisms of natural products also mean more challenges. Our long-term goals are to fully understand the molecular targets and mechanisms of action of anticancer natural products and develop them as novel cancer preventive and therapeutic agents. The specific goal of this Research Topic is to bring together the recent findings of newly identified anticancer natural products, especially those with multiple molecular targets. Papers (Original Research articles or Reviews) which discuss the in vitro and in vivo efficacy and pharmacological and toxicological properties of natural products are also welcome to be submitted. Guidelines for the conception and review of submissions As many anticancer drugs working as cytotoxic compounds have non-selective effects annihilating their potential therapeutic benefits, manuscripts are advised to provide evidence of a significant selectivity towards cancer cells (vs. healthy cells). Specifically, if the studied anticancer drug or modality does not target an oncogenic pathway, the authors should make every effort possible to prove that the cytotoxic or cytostatic effects they have identified exhibit selectivity for cancer cells (ideally 1 log difference in EC50 or IC50) vs. non-malignant cells (eg, fibroblasts or primary culture of cells). The authors should also demonstrate the applicability of their anticancer modalities on a minimum of two well-authenticated cancer cell lines (ideally originating from distinct organs/tissues). For manuscripts dealing with plant extracts or other natural substances/compounds, the composition and the stability of the study material must be described in sufficient detail. In particular, for extracts, chromatograms with characterization of the dominating compound(s) are requested. The level of purity must be proven and included. Please refer to the Four Pillars of Best Practice in Ethnopharmacology, a subset of which concerning general standards in natural product research are applied to all such studies in all sections of Frontiers in Pharmacology.

Book Description
There have been tremendous advances in our understanding of molecular and tumor biology during the past few years. In the field of cancer therapeutics, it is expected that cytotoxic drug approaches will be gradually replaced with treatments based on biological targeted approaches. Hopefully these new targeted therapies will significantly increase efficacy and lack the devastating and troublesome side effects elicited by cytotoxic chemotherapy. This volume is the first book to cover the general topic of targeted cancer therapy. It presents a range of targets such as tumor angiogenesis, cell cycle control and cell signalling, COX-2, apoptosis/cell survival, invasion and metastasis and approaches like kinase inhibitors, antisense, and antibody-based therapeutics. The emphasis is on preclinical development, including target validation, development of biomarkers, strategies for combination approaches, and development of resistance. The particular challenges involved in translating these data to clinical application are discussed. This volume should be of broad general interest to researchers and clinicians involved in cancer therapy as well as other scientists interested in current strategies for cancer treatment.

Book Description
Extensive research into the molecular mechanisms of cancer disease has heralded a new age of targeted therapy. In malignant cells, key proteins that are crucial to tumor growth and survival are now being targeted directly with rationally designed inhibitors. Apart from monoclonal antibodies, small molecule therapeutics such as oncogenic protein kinase inhibitors are attracting a vast amount of investigational attention. This textbook, written by acknowledged experts, provides a broad overview of the small molecules currently used for the treatment of malignant diseases and discusses interesting novel compounds that are in the process of clinical development to combat cancer.

Book Description
Tumor, also known as neoplasm, is a mass or group of tissues that is formed as a result of abnormal growth. It can appear anywhere on the body. Bone, tissues, skin, glands, and organs, all can be affected by tumors. They may be cancerous (malignant), non-cancerous (benign), or precancerous. Malignant tumors can spread to adjacent tissues, glands, or other body parts. Benign tumors pose a low risk of death. They are isolated and do not spread to other body parts or impact neighboring tissues. Precancerous tumors are non-cancerous tumors which may become cancerous if left untreated. Most common types of cancer treatments include targeted therapy (molecularly targeted therapy), hormonal therapy and cytotoxic therapy. There exist two types of targeted therapies, namely, small molecule medicines and monoclonal antibodies. The small molecule medicines are biopharmaceuticals that are so small that they can enter the cancer cells and destroy them. Targeted therapy makes use of monoclonal antibodies which cannot enter into the cells. However, these monoclonal antibodies attack targets outside of cells. In various cases, monoclonal antibodies are used to launch chemo and radiation straight into tumors. This book aims to provide the readers a comprehensive overview of the applications of targeted therapies for the treatment and management of tumors. For all readers who are interested in understanding this therapeutic procedure, it will serve as an excellent guide.
