New Phytologist, Volume 247, Issue 1, Page 233-248, July 2025.Summary Pathogenesis‐related (PR) proteins are diverse stress‐ or pathogen‐induced proteins. Some are associated with specialised metabolism, including proposed functions for anthocyanin biosynthesis. However, data are limited to a few angiosperm species, and the mode(s) of action are uncertain.

Characterization of Opioid Agonist Morphine Derivatives with Emphasis on Medicinal Chemistry
ChemMedChem, Volume 20, Issue 4, February 16, 2025.The aim of synthesizing new opioid compounds is to produce drugs that are more potent, less addictive, and have fewer side effects, such as respiratory depression and constipation. To achieve this, we evaluated the basicity, lipophilicity, and permeability of 30 opioid compounds, including 11 newly synthesized ones, to better understand the ...

The reactions of thebaine with C-nitroso-compounds
, 1972 The reactions of thebaine with nitrosoarenes to form Diels–Alder adducts have been investigated. Reversibility of the addition of a series of parasubstituted nitrosoarenes to thebaine has been qualitatively studied by NMR spectrometry.

FEBS Open Bio, Volume 14, Issue 12, Page 1955-1971, December 2024.We developed the Saccharomyces cerevisiae strains termed Δ10 that exhibit auxotrophic behavior for 10 different nutrients and the plasmids with auxotrophic markers for use in Δ10 strains. Δ10 strains were able to maintain 10 types of plasmids by auxotrophic selection.

The preparation and some reactions of the irontricarbonyl complex of thebaine
, 1969 The methoxycyclohexadiene ring of thebaine readily complexes with Fe(CO)3 to give (I; R = Me). This group alters the reactivity of the thebaine molecule in a number of ways, protecting the diene system and permitting ready fission of the cyclic ether to ...
