Synthesis of Indole Derivatives via Aryl Triazole Ring-Opening and Subsequent Cyclization

Molecules
A metal-free two-step synthetic approach for obtaining indole derivatives from aryl triazole fragment-containing compounds has been developed. In the first step, the Dimroth equilibrium, followed by nitrogen extrusion, Wolff rearrangement, and amine ...

Solvable models of neighbor-dependent nucleotide substitution processes

, 2005
We prove that a wide class of models of Markov neighbor-dependent substitution processes on the integer line is solvable. This class contains some models of nucleotide substitutions recently introduced and studied empirically by molecular biologists.

Mechanisms of base selection by human single-stranded selective monofunctional uracil-DNA glycosylase [PDF]

, 2009
hSMUG1 (human single-stranded selective monofunctional uracil-DNA glyscosylase) is one of three glycosylases encoded within a small region of human chromosome 12. Those three glycosylases, UNG (uracil-DNA glycosylase), TDG (thymine-DNA glyscosylase), and

Biocatalytic Construction of a Chemical Exchange Saturation Transfer Magnetic Resonance Imaging Nucleoside Probe: Synthesis and Evaluation of 5‐Methyl‐5,6‐Dihydrothymidine

Advanced Synthesis &Catalysis, EarlyView.
Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.

Oxidized phospholipids regulate amino acid metabolism through MTHFD2 to facilitate nucleotide release in endothelial cells

Nature Communications, 2018
During atherosclerosis, endothelial cells release purines in response to oxidized phospholipids. Here, Hitzel et al. show that oxidized phospholipids activate an MTHFD2-regulated gene network in endothelial cells which reprograms amino acid metabolism ...

Purine Acquisition and Synthesis by Human Fungal Pathogens

Microorganisms, 2017
While members of the Kingdom Fungi are found across many of the world’s most hostile environments, only a limited number of species can thrive within the human host. The causative agents of the most common invasive fungal infections are Candida albicans,

Role of HIV RNA structure in recombination and speciation: romping in purine A, keeps HTLV away

, 2013
Extreme enrichment of the human immunodeficiency virus (HIV-1) RNA genome for the purine A parallels the mild purine-loading of the RNAs of most organisms.
