Download or read book Chemical Synthesis of Nucleoside Analogues written by Pedro Merino and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compiles current tested and proven approaches to synthesize novel nucleoside analogues Featuring contributions from leading synthetic chemists from around the world, this book brings together and describes tested and proven approaches for the chemical synthesis of common families of nucleoside analogues. Readers will learn to create new nucleoside analogues with desired therapeutic properties by using a variety of methods to chemically modify natural nucleosides, including: Changes to the heterocyclic base Modification of substituents at the sugar ring Replacement of the furanose ring by a different carbo- or heterocyclic ring Introduction of conformational restrictions Synthesis of enantiomers Preparation of hydrolitically stable C-nucleosides Chemical Synthesis of Nucleoside Analogues covers all the major classes of nucleosides, including pronucleotides, C-nucleosides, carbanucleosides, and PNA monomers which have shown great promise as starting points for the synthesis of nucleoside analogues. The book also includes experimental procedures for key reactions related to the synthesis of nucleoside analogues, providing a valuable tool for the preparation of a number of different compounds. Throughout the book, chemical schemes and figures help readers better understand the chemical structures of nucleoside analogues and the methods used to synthesize them. Extensive references serve as a gateway to the growing body of original research studies and reviews in the field. Synthetically modified nucleosides have proven their value as therapeutic drugs, in particular as antiviral and antitumor agents. However, many of these nucleoside analogues have undesirable side effects. With Chemical Synthesis of Nucleoside Analogues as their guide, researchers have a new tool for synthesizing a new generation of nucleoside analogues that can be used as therapeutic drugs with fewer unwanted side effects.

Download or read book DNA Methylation and Cancer Therapy written by Moshe Szyf and published by Springer Science & Business Media. This book was released on 2005-01-20 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: NA methylation has bewildered molecular biologists since Hotchkiss discovered it almost six decades ago (Hotchkiss RDJ. Biol Cem 1948; 175:315-332). The fact that the chemical structure of our D genome consists of two components that are covalently bound, the genetic information that is replicated by the DNA replication machinery ana DNA methylation that is maintainea by independent enzymatic machinery, has redictably stimulated the imagination and curiosity of generations of mo Edular biologists. An obvious question was whether DNA methylation was a bearer of additional information to the genetic information and what was the nature of this information? It was tempting to speculate that DNA me thylation applied some form of control over programming of the genome s expression profile. Once techniques to probe the methylation profile of whole genomes as well as specific genes became available, it became clear that DNA methylation patterns are gene and tissue specific and that patterns of gene expression correlate with patterns of methylation. DNA methylation pat terns emerged as the only component of the chemical structure of DNA that exhibited tissue and cell specificity. This data seemingly provided an attrac tively simple explanation for the longstanding dilemma of how could one identical genome manifest itself in so many different forms in multicellular organisms? The DNA methylation pattern has thus become the only known factor to confer upon DNA a unique cellular identity.

Download or read book New Strategies Targeting Cancer Metabolism written by Galal H. Elgemeie and published by Elsevier. This book was released on 2022-05-17 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Strategies Targeting Cancer Metabolism: Anticancer Drugs, Synthetic Analogues and Antitumor Agents presents up-to-date synthetic strategies for three categories of antimetabolites: antifolates, purines and pyrimidines, the main classes of antimetabolites which are integrated into various pharmaceutical agents. Many of these antimetabolites are considered potent chemotherapeutic agents which have great potential impact on medical research. These main classes of antimetabolites are used in the treatment of critical diseases including cancer, malignancies, autoimmune diseases, and many other non-malignant diseases. Antineoplastic drugs such as alkylating agents which have significant effects are described. Novel synthetic strategies for many anticancer alkylating agents including nitrogen mustards, chlorambucil, melphalan, ifosamide, oxaliplatin and temozolomide are explored. Natural products have offered some of the most significant drugs for treating cancer, as many drugs currently in clinical use are derived from natural products as camptothecins, vinca alkaloids, and derivatives of podophyllotoxin. They provide a contribution that is essential for modern drug discovery and development. In this book, insights into a broad array of novel compounds are reviewed, well-recognized synthetic approaches are emphasized for further anticancer drug development and discovery, and the biological evaluation of novel synthesized compounds are included.

Download or read book Deoxynucleoside Analogs in Cancer Therapy written by Godefridus J Peters and published by Springer Science & Business Media. This book was released on 2007-11-07 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful cancer chemotherapy relies heavily on the application of various deoxynucleoside analogs. Since the very beginning of modern cancer chemotherapy, a number of antimetabolites have been introduced into the clinic and subsequently applied widely for the treatment of many malignancies, both solid tumors and hematological disorders. In the latter diseases, cytarabine has been the mainstay of treatment of acute myeloid leukemia. Although many novel compounds were synthesized in the 1980s and 1990s, no real improvement was made. However, novel technology is now capable of elucidating the molecular basis of several inborn errors as well as some specific malignancies. This has enabled the synthesis of several deoxynucleoside analogs that could be applied for specific malignancies, such as pentostatin and subsequently chlorodeoxyadenosine (cladribine) for the treatment of hairy cell leukemia. Already in the early stage of deoxynucleoside analog development, it was recognized that several of these compounds were very effective in the treatment of various viral infections, such as for the treatment of herpes infections. This formed the basis initially for the design of azidothymidine and subsequently many other analogs, which are currently successfully used for the treatment of HIV infections. As a spin-off of these research lines, some compounds not eligible for development as antiviral agents appeared to be very potent anticancer agents. The classical example is gemcitabine, now one of the most widely applied deoxynucleoside analogs, used for the (combination) treatment of non-small cell lung cancer, pancreatic cancer, bladder cancer, and ovarian cancer.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Now day’s computer-aided drug design considered as a powerful method to design very specific lead compounds that can be developed as drug molecules. Using different in-silico tools, a target is selected and then its structure is defined and determined. After that new chemical/ synthetic compounds can be designed in-silico on the basis of combinatorial chemistry or chosen from an already available chemical library of molecules or library of molecules is generated from a subset of small molecules on the basis of docking and scoring against the particular target. In this study, I attempt to generate 2D QSAR model using small pIC50 values for thirty-eight benzoxazole derivatives binding with C. parvum IMPDH protein resulting correlation coefficient value R2/r2 is 0.7948. Docking results show that out of 38 benzoxazole derivatives, four compounds are most active. The present examination may give the data about potential derivatives of Benzoxazole as chemotherapeutic operators to battle against the expanding weight of Cryptosporidiosis infections.
