study of antimetabolites. by Dilworth Wayne Woolley Download PDF EPUB FB2
Antimetabolite. Antimetabolites are a class of anticancer drugs defined as compounds, structurally similar to natural purine or pyrimidine base, nucleoside or nucleotides, molecules needed to carry out primary metabolic reactions that by virtue of their similarity act as analogues of a normal metabolites, interfere with the normal metabolic processes within cells and, thus, preventing the.
Additional Physical Format: Online version: Woolley, Dilworth Wayne, Study of antimetabolites. New York, Wiley  (OCoLC) Document Type. Antimetabolites are compounds that are structurally similar to required cellular metabolites, but the cells cannot use them in a productive manner.
These antimetabolites are mistaken for the metabolites in cells, and are processed in the cell in a manner analogous to the normal compounds; however, the outcome of this metabolism is nonproductive. Book: A study of antimetabolites. + pp. Abstract: In this book comprising an introduction and 11 chapters the author presents a discussion of the biological functioning of various kinds of essential metabolic substances and their antagonism Cited by: Antimetabolite, a substance that competes with, replaces, or inhibits a specific metabolite of a cell and thereby interferes with the cell’s normal metabolic functioning.
An antimetabolite is similar in structure to a metabolite, or enzymatic substrate, which is normally recognized and acted upon. Antimetabolites are drugs that interfere with one or more enzymes or their reactions that are necessary for DNA synthesis. They affect DNA synthesis by acting as a substitute to the actual metabolites that would be used in the normal metabolism (for example antifolates interfere with the use of folic acid).
A study of antimetabolites. Dilworth Wayne Woolley. Wiley, From inside the book. What people are saying - Write a review. We haven't found any reviews in the usual places. Contents. Introduction Discovery and development of ideas about antimetabo.
An antimetabolite is a chemical that inhibits the use of a metabolite, which is another chemical that is part of normal metabolism. Such substances are often similar in structure to the metabolite that they interfere with, such as the antifolates that interfere with the use of folic acid; thus, competitive inhibition can occur, and the presence of antimetabolites can have toxic effects on.
antimetabolites are a type of chemo drug that interferes with the normal metabolism of cells, which makes them stop growing. doctors often use them to. This book, one of four in a "Cancer Monograph Series" by British authors, summarizes data accumulated about the antimetabolites study of antimetabolites.

Antimetabolites are the most widely used and most efficacious group of anticancer drugs. Antimetabolites are also the oldest rationally designed anticancer drugs, targeted against RNA and DNA, and can, therefore, be considered as the first generation of targeted drugs.
Unfortunately, resistance often develops, leading to the design of new antimetabolites, which either have a novel. Full text Full text is available as a scanned copy of the original print version.

STUDY. PLAY. What are the categories of antimetabolites. MOA. purine analogs, pyrimidine antimetabolites, antifolates; MOA: Unlike alykylators, they are cell cycle specific. Work primarily in the "s" phase of the cell-cycle. Inhibit DNA synthesis by acting as a false pyramidine or purine and incorporating into DNA, or by inhibiting some.
Antimetabolite definition is - a substance that is structurally similar to a metabolite (such as a coenzyme) and that serves to inhibit a particular cellular function (such as DNA synthesis) by interfering with or blocking the metaboliteʼs action.
How to use antimetabolite in a sentence. Examples of antimetabolites include 6-mercaptopurine (6MP), methotrexate, and hydroxyurea. How to pronounce, definition of, audio dictionary, medical dictionary Category.
Purchase Antimetabolites in Biochemistry, Biology and Medicine - 1st Edition. Print Book & E-Book. ISBN Antimetabolites • Antimetabolites are structurally compounds that exist within the cell.
related to normal • Antimetabolites generally interfere with the availability of normal purine or pyrimidine nucleotide precursors, either by inhibiting their synthesis or by competing with them in DNA or RNA synthesis.
• Their maximal cytotoxic. Although it was performed on a poor-prognosis study population, the current trial demonstrates that high doses of antimetabolites are feasible and active in patients with SCNSL, with an ORR of 74% and a 5-year OS rate of 68% for patients who underwent transplantation, which is an evident step forward in the treatment of this disease.
Antimetabolites resemble normal cellular substances and so can subvert normal metabolic pathways in a toxic manner. Three subgroups of antimetabolites.
Antimetabolites as antibiotics that inhibit synthesis of nucleotides needed for nucleic acid synthesis and their mechanisms of action are discussed. Background biochemistry on folic acid metabolism is included. Antibiotics presented are sulfa drugs, p-aminosalicylic acid, dapsone, trimethoprim, and fluorouracil.

These compounds have two distinguishing fea- tures: (i) they resemble in chemical structure some naturally occurring com- pound which is essential in living processes, and (ii) they specifically an- tagonize the biological action of such an essential compound.
