A Universal Nucleoside‐to‐Nucleoside‐5′‐Triphosphate Enzyme Cascade Driven by Polyphosphate

Angewandte Chemie International Edition, EarlyView.
Nucleoside‐5′‐triphosphates (NTPs) are essential components for the generation of nucleic acids, yet their chemical synthesis is hindered by the low yield of nucleoside phosphorylation. Here, we present a universal, two‐enzyme nucleoside‐to‐NTP cascade that is driven by polyphosphate.

Synthesis of novel 2-(2-(6-chloro-9H-purin-9-yl)ethoxy)-6-isobutoxy-tetrahydro-2H-pyran-3-ol as a potential antiviral agent

Molbank, 2006
In this paper we propose the synthesis of 2-(2-(6-chloro-9H-purin-9-yl)ethoxy)-6-isobutoxy-tetrahydro-2H-pyran-3-ol as a new potential antiviral agent Its structure has been confirmed by IR, 1H-NMR, 13C-NMR, UV and Mass spectroscopic data.

Failure of dideoxynucleosides to inhibit human immunodeficiency virus replication in cultured human macrophages. [PDF]

, 1987
Primary human monocyte-derived macrophages (MDM) were shown to have diminished deoxynucleoside kinase activities compared to T lymphoblasts, and a reduced ability to phosphorylate dideoxynucleosides with anti-human immunodeficiency virus (HIV) activity ...

Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]

, 2016
The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

Evaluation of HIV-DNA and inflammatory markers in HIV-infected individuals with different viral load patterns [PDF]

, 2017
Background: Persistent residual viremia (RV) and low grade inflammation and immune activation have been associated with non-AIDS defining events. The impact of persistent RV and HIV-DNA load on immune activation/ inflammation remains unclear.

Chemoselective Difluoromethylation of Nucleosides

Organic Letters
A profiling platform to define the chemoselectivity of the carbene-mediated difluoromethylation of nucleosides is described. First, the optimized reaction conditions for the difluoromethylation of silyl-protected nucleosides are established using TMS-CF2Br and KOAc to form the difluoromethyl carbene in situ.

5‐Methylcytosine Analysis of miRNAs in Minimal Change Disease

Biotechnology and Applied Biochemistry, Volume 73, Issue 3, Page 1137-1150, June 2026.
ABSTRACT Minimal change disease (MCD) is a glomerular disorder, which is the most common cause of nephrotic syndrome in children. Additionally, the prevalence of MCD in adults has been increasing in recent years. During protein synthesis, noncoding RNAs can be regulated through a variety of modifications, which helps preserve biological diversity and ...
