Pharmacology
MeSH Pharmacological Classification
Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues.
Uses & manufacturing
Applications
DescriptionPhenylalanine is an amino acid, which are the building blocks of proteins in your body. This molecule exists in two forms or arrangements: L-phenylalanine and D-phenylalanine. They’re nearly identical but have a slightly different molecular structure. The L-form is found in foods and used to produce proteins in your body, while the D-form can be synthesized for use in certain medical applications . Your body is unable to produce enough L-phenylalanine on its own, so it’s considered an essential amino acid that must be obtained through your diet. It’s found in a wide variety of foods — both plant and animal sources. In addition to its role in protein production, phenylalanine is used to make other important molecules in your body, several of which send signals between different parts of your body. Phenylalanine has been studied as a treatment for several medical conditions, including skin disorders, depression and pain. However, it can be dangerous for people with the genetic disorder phenylketonuria (PKU).
UsesL-phenylalanine (LPA) serves as a building block for the various proteins that are produced in the body. LPA can be converted to L-tyrosine (another amino acid ) and subsequently to L-dopa, norepinephrine, and epinephrine . LPA can also be converted (through a separate pathway) to phenylethylamine, a substance that occurs naturally in the brain and appears to elevate mood.
UsesTyrosol (Metoprolol EP Impurity G) is a phenolic antioxidant.
UsesPhenolic antioxidant.
General Description2-(4-Hydroxyphenyl)ethanol (4-Hydroxyphenethyl alcohol) is a phenolic alcohol commonly present in olive mill wastewater.
