Enantiomers of oxyphenonium bromide. Analytical and pharmacological aspects.

Pharmaceutisch weekblad. Scientific edition, 1987
This thesis focuses on some analytical and pharmacological aspects of enantiomers. Enantiomers always exist as a pair of non-identical mirror-images that resemble each other as a left and a rigbt hand. The configuration around the central (carbon) atom is opposite.

Phosphorescent Iridium Hydrazinonicotinic Acid (HYNIC) Complexes That Bind to Prostate Specific Membrane Antigen: Potential Photodynamic Therapy of Prostate Cancer

Chemistry – A European Journal, EarlyView.
A phosphorescent iridium(III) complex has been prepared with a 6‐hydrazinonicotinic acid (HYNIC) ligand tethered to a lysine‐ureido‐glutamatic acid pharmacophore, which binds to an enzyme, called prostate‐specific membrane antigen (PSMA), which is overexpressed in prostate cancer.

Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System

Chemistry – A European Journal, EarlyView.
Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.

A Low‐Symmetry FeII Tetrahedron From a Flexible Tritopic Ligand

Chemistry – A European Journal, EarlyView.
A highly symmetric and flexible tris‐bidentate tritopic ligand forms an S4 meso homoleptic face‐capped FeII tetrahedron near‐quantitatively in acetonitrile. The addition of nitromethane solvent causes partial isomerization of this meso cage to the racemic homochiral tetrahedron, with the complexity of the system being moderated through solvophobic ...

Stereoselective Higher‐Order [10+4]‐ and [10+6] Cycloadditions Between Two Highly Unsaturated and Ambiphilic π‐Addends

Chemistry – A European Journal, EarlyView.
Aminocatalytically generated isobenzofulvenes and 3‐oxidopyridinium betaines act as ambiphilic reaction partners in orbital‐symmetry‐allowed [10+4] cycloadditions or formally symmetry‐forbidden concerted thermal [10+6] cycloadditions. The reaction furnishes three cycloadducts: one [10+4] cycloadduct and two regioisomeric [10+6] cycloadducts.
