Effect of developmental changes on pharmacokinetics of drugs used in the treatment of infant acute lymphoblastic leukaemia—A comprehensive review

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

Pharmacokinetics of dolutegravir, tenofovir and lamivudine during venous–venous extracorporeal membrane oxygenation (VV‐ECMO): A case report

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
While providing potentially life‐saving cardiorespiratory support for critically ill patients, extracorporeal membrane oxygenation (ECMO) may detrimentally affect pharmacokinetic (PK) performance and concurrent drug efficacy and safety. We describe a patient with Pneumocystis jirovecii pneumonia (PJP) in the context of acquired immunodeficiency ...

Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes

open access: yesChemistryEurope, EarlyView.
Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...

A Michaelis‐Arbuzov‐Type Pathway to a Protected 2ʹ‐Deoxy‐2ʹ‐Selenomethyl‐Adenosine‐3ʹ,5ʹ‐Phosphoroselenolate Guanosine Dinucleotide for Use in Modified m7G Cap Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Here we report a synthesis of the dinucleotide 4 for a projected future total synthesis of the m7G cap 1. Highlights of the route include: 1) a 3ʹ‐H‐phosphonate/5ʹ‐selenocyanate Michaelis‐Arbuzov coupling to forge the 3ʹ,5ʹ‐phosphoroselenolate; 2) an Amosova reductive selenomethylation to install the 2ʹ‐SeMe; 3) a solid CPR II 5ʹ‐O‐phosphitylation; and

One‐Step and Universal Strategy for the Synthesis of Hypermodified Uracil Phosphoramidites acp3U and cmnm5U

open access: yesChemistry – A European Journal, EarlyView.
One‐step, highly efficient, and scalable synthesis of acp3U phosphoramidite is described, as well as a new alternative synthesis of cmnm5U phosphoramidite from a highly versatile intermediate. Latter could be scaled‐up, split, and aliquots turned simultaneously into cmnm5U, nm5U, and mnm5U.

Synthesis and Glycosidase Inhibition Studies of Novel Exoglycals Targeting GH3 Family Enzymes: Insights from Comparative Analysis with Macrolide Antibiotics

open access: yesChemistry – A European Journal, EarlyView.
A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.

Synthesis and Evaluation of the First Generation of Glycosylated Nucleoside Analogues as Potential Inhibitors of the Base J Metabolism in Kinetoplastid Parasites

open access: yesChemistry – A European Journal, EarlyView.
Novel analogues of the kinetoplastid‐specific DNA base J unlock a new way to target parasite epigenetic regulation. Some compounds selectively inhibit Leishmania and Trypanosoma species without harming human cells, revealing a promising route toward innovative antiparasitic therapies.
