Metadoxine is a selective antagonist of the serotonin receptor subtype 5-HT 2B and displays high affinity to the gamma-aminobutyric acid (GABA) transporter. In vitro enzymatic assay revealed that metadoxine reduced the activity of the GABA transaminase enzyme, responsible for the degradation of GABA. Electrophysiological studies also showed ...
ATC code A05 Bile and liver therapy is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Silibinin , also known as silybin (both from Silybum, the generic name of the plant from which it is extracted), is the major active constituent of silymarin, a standardized extract of the milk thistle, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silychristin, silidianin, and others.
Hyoscyamine (also known as daturine or duboisine) is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, the sorcerers' tree, and Atropa belladonna (deadly nightshade).
According to Nichols, the simplest ergoline with definite known psychoactive effects in humans is the lysergamide lysergic acid amide (LSA; ergine). [ 2 ] [ 3 ] Descarboxylysergic acid showed effects in preclinical research suggestive of serotonergic , adrenergic , and dopaminergic activities, for instance prolactin inhibition , oxytocic , and ...
NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
The enzyme takes the end methyl residue from the methionine side chain and adds it to the side chain carboxyl group of L-isoaspartate or D-aspartate to create a methyl ester. Subsequent nonenzymatic reactions result in a rapid transformation to L -succinimide, which is a precursor to aspartate and isoaspartate.
The organic compound citrulline is an α-amino acid. [2] Its name is derived from citrullus, the Latin word for watermelon.Although named and described by gastroenterologists since the late 19th century, it was first isolated from watermelon in 1914 by Japanese researchers Yatarō Koga (古賀彌太郎) and Ryō Ōtake (大嶽了) [3] [4] and further codified by Mitsunori Wada of Tokyo ...
