O‐Terphenyl‐basierte Familie konjugierter Makrozyklen: Selektive Erkennung von Phenylalanin im Wasser und Interaktion mit Insulin

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Diese Studie beschreibt die Herstellung und Eigenschaften einer neuen Familie von o‐Terphenyl‐basierten Makrozyklen, TP[n] (n = 2‐8). Der Trimer bindet Phenylalanin in Wasser sehr effizient und ist dabei zehnmal selektiver als bei anderen Aminosäuren und aromatischen Neurotransmittern.

Immune–proteo–metabolomic changes link to Aβ and tau pathology in Alzheimer disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Tryptophan metabolism is increasingly implicated in Alzheimer's disease (AD), particularly through aryl hydrocarbon receptor (AhR) ligands that influence neuroinflammation. However, their relationships with core AD pathology—amyloid‐β (A) and tau (T) deposition—and associated immune–proteomic alterations remain unclear. METHODS We

Design, Synthesis, and Biological Evaluation of Pseudo‐Natural Products Inspired by Aryloctahydroindole Alkaloids

ChemMedChem, Volume 21, Issue 3, 12 February 2026.
Mesembrine alkaloid pseudo‐natural products were synthesized employing a microwave‐assisted Diels–Alder reaction as a key step. Morphological profiling by cell painting revealed compound‐topology‐dependent mitochondrial fragmentation or inhibition of respiration.

Genome‐Wide Association Analyses in Family Triads and Dyads Following Assisted Reproductive Technology

Genetic Epidemiology, Volume 49, Issue 5, July 2025.
ABSTRACT Genetic selection occurs at different stages before a successful birth. The genetic makeup of a couple may influence the likelihood of needing assisted reproductive technology (ART) to achieve conception. However, frequent early fetal losses may also be perceived as reduced couple fertility and may thus be a contributing factor to the need for

Neuroactive substances specifically modulate rhythmic body contractions in the nerveless metazoon Tethya wilhelma (Demospongiae, Porifera)

Frontiers in Zoology, 2006
Background Sponges (Porifera) are nerve- and muscleless metazoa, but display coordinated motor reactions. Therefore, they represent a valuable phylum to investigate coordination systems, which evolved in a hypothetical Urmetazoon prior to the central ...
