A large number of novel compounds continue to be synthesized and evaluated both by academia and the pharmaceutical industry, which underlines the important interest in this family of drugs. Different ...

The discovery of ArcS, which can utilize a nucleoside as a minimum substrate, provides new insights into the synthesis of precursor molecules for these modified nucleosides. The results of this ...

On Monday, Dr. Michio Hirano, a neurologist at Columbia University, will evaluate 11-month old Charlie Gard, the British boy who is on life support because of a rare, lethal disease called ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

Acute lymphoblastic leukemia is the most common type of childhood leukemia, with about 5,000 children diagnosed in the U.S. each year. Now researchers have synthesized a nonnatural deoxynucleoside ...

Inosine is a nucleoside that occurs naturally in transfer RNAs (tRNAs) and is essential for proper RNA translation. It is commonly found at the wobble position of anticodons, allowing for greater ...

Pathogen recognition is based on the presence of Toll-like receptors (TLRs), which detect pathogen-associated molecular patterns (PAMPs) to coordinate the immune cascade. These receptors are encoded ...

Nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) stop a virus from making copies of itself. They’re used to prevent HIV from replicating. Learn how NRTIs work and what side effects they ...

Nucleoside analogues can induce toxic effects on mitochondria by inhibiting the human DNA polymerase γ. The toxic effects can range from increased serum lactate levels to potentially fatal lactic ...
