DNA topoisomerase inhibitors Understanding

DNA topoisomerase inhibitors: Overview

Topoisomerases are essential and ubiquitous enzymes that regulate DNA topology by making temporary single- (type I) or double-strand DNA breaks (type II) [1], [2]. The DNA double helix needs to be unwound for processes such as DNA replication or transcription to take place, giving rise to the accumulation of positive supercoils ahead of transcription bubbles and replication forks, and negative supercoils or pre-catenanes behind. Topoisomerases relax supercoiled DNA and decatenate DNA to allow DNA transcription and replication to take place and are essential for genome stability

Function - DNA topoisomerases are enzymes that catalyze the alteration of DNA topology with transiently induced DNA strand breakage, essential for DNA replication. Topoisomerases are validated cancer chemotherapy targets. Anticancer agents targeting Topoisomerase I and II have been in clinical use and proven to be highly effective, though with significant side effects. There are tremendous efforts to develop new generation of topoisomerase inhibitors.

DNA topoisomerase inhibitors - Topoisomerase inhibitors are chemical compounds that block the action of topoisomerases, which are broken into two broad subtypes: type I topoisomerases (TopI) and type II topoisomerases (TopII). Topoisomerase plays important roles in cellular reproduction and DNA organization, as they mediate the cleavage of single and double stranded DNA to relax supercoils, untangle catenanes, and condense chromosomes in eukaryotic cells. Topoisomerase inhibitors influence these essential cellular processes. Some topoisomerase inhibitors prevent topoisomerases from performing DNA strand breaks while others, deemed topoisomerase poisons, associate with topoisomerase-DNA complexes and prevent the re-ligation step of the topoisomerase mechanism. These topoisomerase-DNA-inhibitor complexes are cytotoxic agents, as the un-repaired single and double stranded DNA breaks that they cause can lead to apoptosis and cell death. Because of this ability to induce apoptosis, topoisomerase inhibitors have gained interest as therapeutics against infectious and cancerous cells.

DNA topoisomerase inhibitors Emerging Drugs Chapters

This segment of the DNA topoisomerase inhibitors report encloses its detailed analysis of various drugs in different stages of clinical development, including phase III, II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

DNA topoisomerase inhibitors Emerging Drugs

• DNV3837: Deinove

DNV3837 is a water soluble prodrug that is rapidly dephosphorylated after intravenous administration in humans to produce DNV3681, the active form of the drug. Its structure results from the combination of two active moieties: a fluoroquinolone that inhibits bacterial DNA gyrase to interfere with replication of the bacterial genome and an oxazolidinone that inhibits initiation of bacterial protein synthesis. The drug is in phase II of clinical development for the treatment of Clostridium difficile infections.

• CXD 201: Celleron Therapeutics

CXD 201, a proprietary topoisomerase inhibitor, is being developed by Celleron Therapeutics (spin-off of Oxford University) and Nuance Biotech for the treatment of patients with colorectal cancer.
