Nitrogen-containing heterocycles derived from isoquinoline alkaloids

open access: yes, 2009
Reactions of the isoquinoline alkaloids, aporphine, papaverine, pavine, and berberine have been studied . The main aim of the work was to explore a potential route to the new strained aza(l,9)phenanthrenophane derivatives 23a, 23b, and 24 using the ...

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

open access: yesAngewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Combined Gravimetric, Electrochemical, and Computational Research on Benzothiophene Derivatives as Effective Corrosion Inhibitors for Mild Steel

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Four benzothiophenes, thianaphthene (BT‐1), 3‐bromothianaphthene (BT‐2), benzo[b]thiophene‐2‐carboxaldehyde (BT‐3), and benzo[b]thiophene‐2‐carbonitrile (BT‐4), were tested as mild steel corrosion inhibitors in 1‐M HCl. The compounds have the similar benzothiophene core but differ in the substituents bound to the ring.

Discovery of CRBN‐based molecular glue degraders targeting WIZ transcription factor

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This work reports the discovery of 9l, a novel cereblon‐based molecular glue degrader which targets the WIZ transcription factor. Compound 9l facilitates WIZ‐CRBN ternary complex formation to degrade WIZ, subsequently inducing γ‐globin expression in HUDEP‐2 cells and highlighting its potential as a sickle cell disease therapy.

High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Protein hydrolysates in cell culture: Toward multi‐omics characterization

open access: yesBiotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.
