The neurotoxicity of pyridinium metabolites of haloperidol

open access: yesPostępy Higieny i Medycyny Doświadczalnej, 2015
Haloperydol is a butyrophenone, typical neuroleptic agent characterized as a high antipsychotics effects in the treatment of schizophrenia and in palliative care to alleviation many syndromes, such as naursea, vomiting and delirium. Clinical problems occurs during and after administration of the drug are side effects, particularly extrapyrramidal ...

Photosensitizing Au(I) Catalysis With Coumarins

open access: yesChemistry – A European Journal, EarlyView.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Precision Chemistry for Protein Lysine Modification

open access: yesChemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
