To increase the solubility of L-3,4-dihydroxyphenylalanine (DOPA) and dopamine (DA) incorporated in liposomes, it was suggested to convert them into ammonium and 1-adamantylammonium borate complexes. The structure of these complexes was studied by 11B and 1H NMR, IR, and mass spectrometry and conductometry. The liposomic form of the complexes is characterized by a high active compound/lipid molar ratio (0.5). Catechols in the form of complex salts are retained better within the inner volume of liposomes.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008081	Liposomes	Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

D009682	Magnetic Resonance Spectroscopy	Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

D001881	Borates	Inorganic or organic salts and esters of boric acid.	Borate
D002396	Catechols	A group of 1,2-benzenediols that contain the general formula R-C6H5O2.	Pyrocatechols,o-Dihydroxybenzenes,ortho-Dihydroxybenzenes,o Dihydroxybenzenes,ortho Dihydroxybenzenes
D004295	Dihydroxyphenylalanine	A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.	Dopa,3,4-Dihydroxyphenylalanine,3-Hydroxy-DL-tyrosine,Dihydroxyphenylalanine Hydrochloride, (2:1),beta-Hydroxytyrosine,3 Hydroxy DL tyrosine,3,4 Dihydroxyphenylalanine,beta Hydroxytyrosine
D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D000547	Amantadine	An antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake.	1-Aminoadamantane,Adamantylamine,Adekin,Aman,Amanta,Amanta-HCI-AZU,Amanta-Sulfate-AZU,Amantadin AL,Amantadin AZU,Amantadin Stada,Amantadin-neuraxpharm,Amantadin-ratiopharm,Amantadina Juventus,Amantadina Llorente,Amantadine Hydrochloride,Amantadine Sulfate,Amixx,Cerebramed,Endantadine,Gen-Amantadine,Infecto-Flu,Infex,Mantadix,Midantan,PMS-Amantadine,Symadine,Symmetrel,Viregyt,Wiregyt,tregor,1 Aminoadamantane,AL, Amantadin,AZU, Amantadin,Amanta HCI AZU,Amanta Sulfate AZU,AmantaHCIAZU,AmantaSulfateAZU,Amantadin neuraxpharm,Amantadin ratiopharm,Amantadinneuraxpharm,Amantadinratiopharm,Gen Amantadine,GenAmantadine,Hydrochloride, Amantadine,Infecto Flu,InfectoFlu,Juventus, Amantadina,Llorente, Amantadina,PMS Amantadine,PMSAmantadine,Stada, Amantadin,Sulfate, Amantadine
