Chemically Regulated STING‐Activating Prodrugs of Deoxyribose Cyclic Dinucleotides Elicit Robust Immune Activation and Durable Antitumor Immunity

Angewandte Chemie, EarlyView.
All three diastereoisomers of an esterase‐sensitive phosphotriester dCDN prodrug demonstrate improved activity. The (Rp,Rp) diastereoisomer shows the highest activity with an EC50 of 1.7 nM in STING activation and displays the most pronounced antitumor activity via intravenous administration, significantly suppressing tumor proliferation, extending the

Phosphodiesterases 4B and 4D Differentially Regulate cAMP Signaling in Calcium Handling Microdomains of Mouse Hearts

Cells
The ubiquitous second messenger 3′,5′-cyclic adenosine monophosphate (cAMP) regulates cardiac excitation-contraction coupling (ECC) by signaling in discrete subcellular microdomains.

Saprotrophic and Ectomycorrhizal Fungi Contribute Differentially to Organic P Mobilization in Beech-Dominated Forest Ecosystems

Frontiers in Forests and Global Change, 2020
Phosphorus (P) is an essential nutrient, but European forest ecosystems are experiencing widespread declines in soil P concentrations. To clarify the roles of ectomycorrhizal (EM) and saprotrophic (SAP) fungi in P cycling in forest soils that differ in ...

The Effects of Acute and Chronic Selective Phosphodiesterase 1 Inhibition on Smooth Muscle Cell-Associated Aging Features

Frontiers in Pharmacology, 2022
Age-related cardiovascular diseases (CVDs) remain among the leading global causes of death, and vascular smooth muscle cell (VSMC) remodeling plays an essential role in its pathology.

Phosphodiesterase induction in Dictyostelium discoideum by inhibition of extracellular phosphodiesterase activity [PDF]

Developmental Biology, 1982
Adenosine 3’,5’-monophosphate (cAMP) is a chemoattractant in Dictyostelium discoideum; it also induces phosphodiesterase activity. Recently it was shown that N’-(aminohexyl)adenosine 3’,5’-monophosphate (hexyl-cAMP) effectively induced phosphodiesterase activity, while this compound was chemotactically inactive and did not effectively bind to the cell ...

Progressive Parkinsonism in PPP2R5D‐Related Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT PPP2R5D‐related neurodevelopmental disorder (Houge–Janssens syndrome type 1) is a rare autosomal dominant condition characterized by macrocephaly, intellectual disability, and epilepsy. Progressive parkinsonism is an emerging adult phenotype that neurologists should be aware of since timely genetic diagnosis opens the door to disease‐modifying

Glutathione‐Responsive Acyl‐Modifications for Targeted RNA Decaging and Prolonged Protein Synthesis

Angewandte Chemie, EarlyView.
The self‐immolation of disulfide‐based mRNA modifications in response to endogenous glutathione (GSH) promotes a gradual release of translatable mRNA within the cell, leading to improved nuclease resistance, tunable release properties, and a significant increase (up to 600%) of target protein production over time. This strategy offers an exciting proof

Mycophenolate Mofetil Treatment Reduces the Risk of Treatment Escalation Due to Vascular Complications in Limited Cutaneous Systemic Sclerosis: Emulation of a Target Trial From the Italian Rheumatology Society SPRING Registry

Arthritis Care &Research, EarlyView.
Objective Mycophenolate mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon because of the lower fibrotic burden and the predominance of vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function.

Eukaryotic-type Ser/Thr protein kinase mediated phosphorylation of mycobacterial phosphodiesterase affects its localization to the cell wall

Frontiers in Microbiology, 2016
Phosphodiesterase enzymes, involved in cAMP hydrolysis reaction, are present throughout phylogeny and their phosphorylation mediated regulation remains elusive in prokaryotes.

The Phosphodiesterases in the Rat Pancreas [PDF]

European Journal of Biochemistry, 1970
The purification of two phosphodiesterases found in the rat pancreas is described. The phosphodiesterase I, an enzyme of the snake venom type, has been purified about 500 times, the phosphodiesterase II, an enzyme of the spleen type, about 60 times. The phosphodiesterase I activity, optimal at a pH of about 9.0, is completely dependent on the presence ...
