Stimuli‐Responsive Chemical Systems That Mimic Biological Dynamics

Chemistry – A European Journal, EarlyView.
Chemists are designing synthetic systems that mimic life's dynamic behaviors, such as motion, sensing, adaptation, and compartmentalization, by integrating reaction networks with stimuli like light, pH, and chemical fuels. This mini‐review surveys molecular machines, responsive materials, nucleic acid networks, and artificial cells, highlighting how ...

High‐Affinity Peptide‐Drug Conjugate Ligands for the TRIM24 PHD and Bromodomain

Chemistry – A European Journal, EarlyView.
We report a series of bivalent peptide‐drug conjugate (PDC) ligands for tripartite motif‐containing protein 24 (TRIM24). These ligands simultaneously engage the PHD and BRD of TRIM24 through an intramolecular (in cis) binding mode, resulting in high affinity binding.

Cyclic Tetraindoles With a Cyclooctatetraene Core: Controlling Planarity and Antiaromatic Character via N‐Alkylation

Chemistry – A European Journal, EarlyView.
We report cyclic tetraindole derivatives incorporating a central cyclooctatetraene (COT) ring, where molecular distortion is tuned by N‐alkylation. Increasing planarity through ethylene linkers enhances π‐conjugation and antiaromaticity, accompanied by red‐shifted absorption, lower oxidation potentials, and a reduced HOMO–LUMO gap, providing insights ...

Titanium‐Catalyzed Intermolecular Hydrothiomethylation of Alkenes

Chemistry – A European Journal, EarlyView.
Hermetically sealable, inexpensive 42‐well aluminum reactor blocks are used to explore new reactivities of air‐ and moisture‐sensitive titanium catalysts. As a result, methyl sulfides undergo efficient α‐alkylation with alkenes in the presence of a titanium catalyst precursor, a formamidinato ligand, and a Lewis acid, yielding branched ...

Synthesis, characterization, and performance of x_MoO3/Z‐22 and x_MoO3/MMP catalysts for biodiesel production

The Canadian Journal of Chemical Engineering, EarlyView.
Methyl transesterification of soybean oil using heterogeneous catalysts for biodiesel production. Abstract The growing global demand for renewable fuels has driven the search for efficient catalysts in biodiesel production. This study presents the synthesis and characterization of x_MoO3/Z‐22 and x_MoO3/MMP heterogeneous catalysts, and evaluates the ...
