The Interaction of Histamine H₃ and Dopamine D₁ Receptors on Hyperkinetic Alterations in Animal Models of Parkinson’s Disease

Pharmaceuticals
Parkinson’s disease is associated with the loss of more than 40% of dopaminergic neurons in the substantia nigra pars compacta. One of the therapeutic options for restoring striatal dopamine levels is the administration of L-3,4-dihydroxyphenylalanine (L-

A novel approach to tyrosinase-based biosensors: Electrode reactions and biological measurement

Biosensors and Bioelectronics: X
This study introduces a novel tyrosinase-based biosensor designed to simultaneously detect tyrosinase, tyrosine, L-DOPA, and L-DOPA quinone. The biosensor, designated as GCE/GNP/Cys/Chit/Tyrase, was developed by immobilizing tyrosinase on a modified ...

3,4-Dihydroxyphenylalanine Peptides as Nonperturbative Quantum Dot Sensors of Aminopeptidase

, 2016
Fluorescence-based assays for hydrolases that cleave within the substrate (endopeptidases) are common, while developing substrates for proteases that selectively cleave from peptide termini (exopeptidases) is more challenging, since the termini are ...
