DNA

(biochemistry)

DNA

deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses). The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA is self-replicating, plays a central role in protein synthesis, and is responsible for the transmission of hereditary characteristics from parents to offspring

CMX001 is a broad-spectrum antiviral agent with demonstrated activity against multiple double-stranded DNA viruses, initially being developed by Chimerix for the treatment of viral infections in immunocompromised transplant patients.

CMX001 has demonstrated broad-spectrum activity in preclinical tests against double-stranded DNA viruses - including CMV - and has been well-tolerated to date among volunteers and patients.
DNA viruses, including herpesviruses and adenoviruses (AdVs), have also been detected in bats, although with less clear implications regarding the role of bats as sources of infection for other mammals (5-8).
The two lead molecules, IQP-0568 and IQP-0589 have also been shown to be active non-nucleoside inhibitors of HIV replication, but inactive against a panel of other RNA and DNA viruses, suggesting specificity for antiviral activity against viruses that encode a reverse transcriptase.
Hypotheses such as possible arthropod-borne or parasite-associated transmission require careful evaluation, bearing in mind that parvoviruses, in common with other DNA viruses, are highly host species specific, and no other instances of vector-borne transmission in this virus family have been recorded.
Estimated sales of antivirals to combat both DNA viruses, including poxviruses, herpesviruses and adenoviruses, as well as RNA viruses such as rubella virus and orthomyxoviruses, rose by nearly 20% from 2004 to 2006, with report findings showing a continuing growth trend resulting in a more than 9% cumulative annual growth rate from 2004 to 2011.
Polyomaviruses are small nonenveloped DNA viruses, with a double-stranded circular DNA genome of [approximately equal to]5 kb packaged within a capsid 45-50 nm in diameter and composed of 3 proteins: VP1, VP2, and VP3 (3).
Herpes viruses are double-stranded DNA viruses that cause common infections in humans, including herpes, CMV, chickenpox, shingles, mono, measles, and Karposi Sarcoma.
Polyomaviruses (PyVs) are highly prevalent, small DNA viruses, capable of persistence in the host.
One of the causes of oral lesions is a group of DNA viruses, human papilloma viruses, which induce hyperplastic lesions in the oral soft tissue such as papillomas, warts, condylomata and focal epithelial hyperplasia.
Resemblances between these two double-stranded DNA viruses, which infect very different hosts, suggest an evolutionary relationship not previously observed.
