Effects of cocaethylene on dopamine and serotonin synthesis in Long–Evans and Sprague–Dawley brains [PDF]

, 1998
We examined the behavioral and neurochemical effects of cocaethylene treatment in Long–Evans ( LE). and Sprague–Dawley (SD) rats. Cocaethylene-induced behaviors were significantly less in LE rats.

Efficient production of salvianic acid A from l-dihydroxyphenylalanine through a tri-enzyme cascade

Bioresources and Bioprocessing, 2023
Salvianic acid A (SAA), used for treating cardiovascular and cerebrovascular diseases, possesses several pharmacological properties. However, the current methods for the enzymatic synthesis of SAA show low efficiency.

Effect of Selective Serotonin Reuptake Inhibitors via 5-HT1A Receptors on L-DOPA-Induced Rotational Behavior in a Hemiparkinsonian Rat Model

Journal of Pharmacological Sciences, 2012
l-Dihydroxyphenylalanine (l-DOPA) is considered the gold standard for the treatment of Parkinson’s disease (PD). However, long-term administration of l-DOPA can induce abnormal side effects.

Synthesis of tripodal catecholates and their immobilization on zinc oxide nanoparticles [PDF]

, 2015
A common approach to generate tailored materials and nanoparticles (NPs) is the formation of molecular monolayers by chemisorption of bifunctional anchor molecules. This approach depends critically on the choice of a suitable anchor group.

The Use of the Calcitonin Minimal Recognition Module for the Design of DOPA-Containing Fibrillar Assemblies

Nanomaterials, 2014
Amyloid deposits are insoluble fibrous protein aggregates, identified in numerous diseases, which self-assemble through molecular recognition. This process is facilitated by short amino acid sequences, identified as minimal modules.

Silk/Natural Rubber (NR) and 3,4-Dihydroxyphenylalanine (DOPA)-Modified Silk/NR Composites: Synthesis, Secondary Structure, and Mechanical Properties

Molecules, 2020
Silk composites with natural rubber (NR) were prepared by mixing degummed silk and NR latex solutions. A significant enhancement of the mechanical properties was confirmed for silk/NR composites compared to a NR-only product, indicating that silk can be ...

PET Studies of Cerebral Levodopa Metabolism: A Review of Clinical Findings and Modeling Approaches [PDF]

, 2009
[18F]Fluoro-3,4-dihydroxyphenyl-l-alanine (FDOPA) was one of the first successful tracers for molecular imaging by positron emission tomography (PET), and has proven immensely valuable for studies of Parkinson’s disease.

l-3,4-Dihydroxyphenylalanine induces ptosis through a GPR143-independent mechanism in mice

Journal of Pharmacological Sciences, 2016
Through its conversion to dopamine by aromatic l-amino acid decarboxylase (AADC), l-3,4-dihydroxyphenylalanine (l-DOPA) replenishes depleted brain dopamine in Parkinson's disease patients. We recently identified GPR143 as a candidate receptor for l-DOPA.

Rheology and Gelation of Hyaluronic Acid/Chitosan Coacervates

Biomolecules, 2022
Hyaluronic acid (HA) and chitosan (CHI) are biopolyelectrolytes which are interesting for both the medical and polymer physics communities due to their biocompatibility and semi-flexibility, respectively.
