Simultaneous liquid-chromatographic determination of 3,4-dihydroxyphenylglycol, catecholamines, and 3,4-dihydroxyphenylalanine in plasma, and their responses to inhibition of monoamine oxidase.

Clinical Chemistry, 1986
This is a reversed-phase liquid-chromatographic method, with electrochemical detection, for simultaneously measuring, in plasma, the concentrations of the catecholamine precursor dihydroxyphenylalanine (DOPA); the endogenous catecholamines norepinephrine,

Non-leaching antimicrobial surfaces through polydopamine bio-inspired coating of quaternary ammonium salts or an ultrashort antimicrobial lipopeptide. [PDF]

, 2012
Bacterial fouling on surfaces significantly increases the resistance of bacteria toward antibiotics, which leads to medical complications and a corresponding financial burden.

In Vivo Biosynthesis and Direct Incorporation of Non‐Canonical Amino Acids into Proteins

ChemBioChem, Accepted Article.
Autonomous cells are engineered biological systems capable of biosynthesising and directly incorporating non‐canonical amino acids (ncAAs) into proteins. These systems have the potential to extend the applicability of the genetic code to enable large‐scale fermentative production of proteins carrying ncAAs.

Maladaptive plasticity in levodopa-induced dyskinesias and tardive dyskinesias: old and new insights on the effects of dopamine receptor pharmacology. [PDF]

, 2014
Maladaptive plasticity can be defined as behavioral loss or even development of disease symptoms resulting from aberrant plasticity changes in the human brain.

Synthesis and Biological Characterization of 4,4‐Difluoro‐3‐(phenoxymethyl)piperidine Scaffold as Dopamine 4 Receptor (D4R) Antagonist in vitro Tool compounds

ChemMedChem, EarlyView.
The work presents details of the efforts to design and characterize novel D4 inhibitors. A new 4,4‐difluoropiperidine ether series that confers improved potency and selectivity for D4 versus the other dopamine receptor subtypes is identified. Extensive structure‐activity relationship around this privileged group identifies the key structural changes to

Radioenzymatic assay of DOPA (3,4-dihydroxyphenylalanine).

Clinical Chemistry, 1978
Abstract We modified the single-isotope radioenzymatic assay for catecholamines [Life Sci. 21, 625 (1977)] to assay 3, 4-dihydroxyphenylalanine (DOPA). DOPA decarboxylase is used to convert DOPA to dopamine, which concurrently is converted to [3H]-3-O-methyldopamine in the presence of catechol-O-methyltransferase and [methyl-3H]-S ...

An actinomycete producing L-3,4-dihydroxyphenylalanine from L-tyrosine [PDF]

, 1979
An actinomycete was isolated during a soil screening programme to obtain L-3,4-dihydroxyphenylalanine producers. A mutant of this organism was isolated by chemical mutagenesis and it accumulated 1 g/litre L-dihydroxyphenylalanine when grown on L-tyrosine.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
