The Role of N6‐Methyladenosine Modification in Health and Disease
MedComm, Volume 7, Issue 6, June 2026.N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides
Angewandte Chemie, Volume 138, Issue 22, 25 May 2026.A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Angewandte Chemie, Volume 138, Issue 22, 25 May 2026.We have established a set of design rules which combine Pd(II) metal coordination, complementary geometries, complementary interligand hydrogen bonding and π─π interactions for predictable self‐assembly of Pd(II)‐based species such as metallo‐foldamers, cyclic species a metallo‐interlocked clippane. The species persist in a combinatorial mixture due to

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.ABSTRACT Syntaxin‐binding protein 1 (STXBP1) mutations lead to severe epilepsy, intellectual disability, developmental delay, and movement disorder. Effective treatments for these conditions do not exist. Recent studies in Munc18‐1 (STXBP1) C. elegans models demonstrate that 4‐phenylbutyrate (4‐PBA) or related pharmacological chaperones stabilize ...

Pest Management Science, Volume 82, Issue 6, Page 5662-5671, June 2026.Baseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...

Structural insights into the binding mode of the hypnotic drug vornorexant to orexin receptors
Acta Crystallographica Section F, Volume 82, Issue 6, Page 201-207, June 2026.The crystal structure of the human orexin type 2 receptor–vornorexant complex (3.29 Å resolution) and orexin type 1 receptor docking revealed a conserved U‐shaped binding conformation, explaining the high affinity and balanced dual antagonism of this dual orexin receptor antagonist. The structural data validate the rational design that incorporated a 1,

ChemMedChem, Volume 21, Issue 10, 27 May 2026.A protocol guided by ligand‐based pharmacophore modeling and structure‐based virtual screening enabled the identification of 1H‐pyrazol‐5‐ol derivatives as novel inhibitors of the SARS‐CoV‐2 spike protein. The lead inhibitors, C‐3 and C‐4, could serve as templates for the design of potent antiviral agents targeting viral entry into host cells ...
