Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Vitamin E Phosphate Nucleoside Prodrugs: A Platform for Intracellular Delivery of Monophosphorylated Nucleosides

Pharmaceuticals, 2018
Vitamin E phosphate (VEP) nucleoside prodrugs are designed to bypass two mechanisms of tumor resistance to therapeutic nucleosides: nucleoside transport and kinase downregulation.

Synthetic Hydrogels Incorporating Hydrolytic/Nonhydrolytic Macromer Ratios Exhibit Improved Tunability of In Vivo Degradation and Immune Responses

Advanced Healthcare Materials, EarlyView.
A synthetic 4‐arm maleimide‐terminated poly(ethylene glycol) (PEG‐4MAL) hydrogel system that combines hydrolytic ester‐linked macromer (PEG‐4eMAL) with nondegradable amide‐linked macromer (PEG‐4aMAL) in various stoichiometric ratios to tune the degradability rate. The macromers are crosslinked with dithiothreitol via thiol‐maleimide click reaction. The

Purine nucleosides replace cAMP in allosteric regulation of PKA in trypanosomatid pathogens

eLife
Cyclic nucleotide binding domains (CNB) confer allosteric regulation by cAMP or cGMP to many signaling proteins, including PKA and PKG. PKA of phylogenetically distant Trypanosoma is the first exception as it is cyclic nucleotide-independent and ...

Construction of an Isonucleoside on a 2,6-Dioxobicyclo[3.2.0]-heptane Skeleton

Molecules, 2015
We have built a new isonucleoside derivative on a 2,6-dioxobicyclo[3.2.0]heptane skeleton as a potential anti-HIV agent. To synthesize the target compound, an acetal-protected dihydroxyacetone was first converted to a 2,3-epoxy-tetrahydrofuran ...

Characterisation of multiple substrate-specific (d)ITP/(d)XTPase and modelling of deaminated purine nucleotide metabolism [PDF]

, 2011
To be viable, organisms possess a number of (deoxy)nucleotide phosphohydrolases, which hydrolyze these nucleotides removing them from the active NTP and dNTP pools. Deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP,

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

Advanced Healthcare Materials, EarlyView.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

Functional Characterization of the Saccharomyces cerevisiae Equilibrative Nucleoside Transporter 1 (ScENT1)

Molecules, 2018
Equilibrative nucleoside transporters (ENTs) are polytopic membrane transporters responsible for the translocation of nucleosides, nucleobases—to a lesser extent—and nucleoside analog therapeutics across cellular membranes.

Preparation of 4 '-spirocyclobutyl nucleoside analogues as novel and versatile adenosine scaffolds

, 2019
Despite the large variety of modified nucleosides that have been reported, the preparation of constrained 4 '-spirocyclic adenosine analogues has received very little attention.

Nevirapine versus Efavirenz for patients co-infected with HIV and Tuberculosis: A Randomised Non-Inferiority Trial [PDF]

, 2013
BACKGROUND: In countries with a high incidence of HIV and tuberculosis co-infection, nevirapine and efavirenz are widely used as antiretroviral therapy but both interact with antituberculosis drugs. We aimed to compare efficacy and safety of a nevirapine-
