Über die Rolle von Wasserstoffwanderungen im Taxadiensystem

open access: yesAngewandte Chemie, Volume 137, Issue 13, March 24, 2025.
Es ist bekannt, dass Protonenwanderungen über große Entfernungen eine Rolle bei der Biosynthese von Taxa‐4,11‐dien spielen. Diese Studie zeigt die Beteiligung von Wasserstoffübertragungen über große Entfernungen auch an der massenspektrometrischen Fragmentierung, und kombinierte Ansätze durch ortsspezifische Mutagenese und enzymatische Umwandlung ...

Environmentally Friendly Antifouling Metabolites from Red Sea Organisms

open access: yesJournal of Chemistry, Volume 2019, Issue 1, 2019., 2019
Seventy‐one marine organisms representing different classes of marine fauna and flora were collected from the Red Sea. They include sponges, hydrozoan, soft corals, sea cucumber, ascidian, cyanobacteria, and macroalgae. The methanolic extracts were evaluated for their toxicity and settlement inhibition effects by using cultured Balanus amphitrite ...

Ovatodiolide of Anisomeles indica Exerts the Anticancer Potential on Pancreatic Cancer Cell Lines through STAT3 and NF‐κB Regulation

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2016, Issue 1, 2016., 2016
Pancreatic cancer is the eighth leading cause of cancer death worldwide. Patients with pancreatic cancer are normally diagnosed at an advanced stage and present poor survival rate. Ovatodiolide (OV), a bioactive macrocyclic diterpenoid isolated from Anisomeles indica, showed cytotoxicity effects in pancreatic cancer cells by inhibiting cell ...

Novel phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon Gothan reveals close affinity with extant Podocarpaceae (Coniferales)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 2, Page 469-478, March 2025.
We perform a phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon to understand the systematic relationship with extant conifers. Data come from four nucleotide regions (trnL‐F, trnK‐matK, rbcL, psbA‐trnH), xylological characters, and biomolecular composition of five extant conifer families and extinct Xenoxylon. Using maximum parsimony in
