Valbenazine is a prodrug which is an ester of [+]-α- dihydrotetrabenazine (DTBZ) with the amino acid L - valine. It is extensively hydrolyzed to the active metabolite DTBZ. Plasma protein binding of valbenazine is over 99%, and that of DTBZ is about 64%. The biological half-life of both valbenazine and DTBZ is 15 to 22 hours.
Valine (symbol Val or V) [4] is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH 3 + form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid.
Cysteine (symbol Cys or C; [5] / ˈsɪstɪiːn /) [6] is a semiessential [7] proteinogenic amino acid with the formula HOOC−CH (−NH2)−CH2−SH. The thiol side chain in cysteine often participates in enzymatic reactions as a nucleophile. Cysteine is chiral, but both D and L -cysteine are found in nature.
Glutamic acid (symbol Glu or E; [4] the anionic form is known as glutamate) is an α- amino acid that is used by almost all living beings in the biosynthesis of proteins. It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use.
Leucine (symbol Leu or L) [3] is an essential amino acid that is used in the biosynthesis of proteins.Leucine is an α-amino acid, meaning it contains an α-amino group (which is in the protonated −NH 3 + form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain isobutyl group, making it a non ...
Theanine. Theanine / ˈθiːəniːn /, commonly known as L-theanine and sometimes L-gamma-glutamylethylamide or N5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L -glutamate and L -glutamine and is found primarily in particular plant and fungal species. [3][4] It was discovered as a constituent of green tea in ...
Isoleucine (symbol Ile or I) [1] is an α-amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a hydrocarbon side chain with a branch (a central carbon atom bound to three other ...
Valinomycin is a naturally occurring dodeca depsipeptide used in the transport of potassium and as an antibiotic. Valinomycin is obtained from the cells of several Streptomyces species, S. fulvissimus being a notable one. It is a member of the group of natural neutral ionophores because it does not have a residual charge.
