Syntheses and characterizations of the in vivo replicative bypass and mutagenic properties of the minor-groove O2-alkylthymidine lesions. [PDF]

open access: yes, 2014
Endogenous metabolism, environmental exposure, and treatment with some chemotherapeutic agents can all give rise to DNA alkylation, which can occur on the phosphate backbone as well as the ring nitrogen or exocyclic nitrogen and oxygen atoms of ...

Effective DNA Inhibitors of Cathepsin G by In Vitro Selection [PDF]

open access: yes, 2008
Cathepsin G (CatG) is a chymotrypsin-like protease released upon degranulation of neutrophils. In several inflammatory and ischaemic diseases the impaired balance between CatG and its physiological inhibitors leads to tissue destruction and platelet ...

Synthesis of oligodeoxyribonucleotide N3′→P5′ phosphoramidates

open access: yesNucleic Acids Research, 1995
An efficient synthesis of the novel nucleic acid analogs oligodeoxyribonucleotide N3'-->P5' phosphoramidates, where the 3'-oxygen is substituted by a 3'-nitrogen, is described. Synthesis of the title compounds was accomplished by the following synthetic steps. First, 5'-O-DMT base-protected-3'-amino-2',3'-dideoxynucleosides were prepared.

Highly efficient 5\u27 capping of mitochondrial RNA with NAD+ and NADH by yeast and human mitochondrial RNA polymerase [PDF]

open access: yes, 2018
Bacterial and eukaryotic nuclear RNA polymerases (RNAPs) cap RNA with the oxidized and reduced forms of the metabolic effector nicotinamide adenine dinucleotide, NAD+ and NADH, using NAD+ and NADH as non-canonical initiating nucleotides for transcription
