An enzyme that catalyzes the oxidation of BENZOATE to 4-hydroxybenzoate. It requires IRON and tetrahydropteridine.
Derivatives of BENZOIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the carboxybenzene structure.
A surface anesthetic that acts by preventing transmission of impulses along NERVE FIBERS and at NERVE ENDINGS.
Compounds consisting of the cycloheptene ring with one or two BENZENE rings fused to it.
A group of two-ring heterocyclic compounds consisting of a benzene ring fused to a diazepine ring.
Compounds based on benzene fused to oxole. They can be formed from methylated CATECHOLS such as EUGENOL.
Organic compounds containing a BENZENE ring attached to a flavone group. Some of these are potent arylhydrocarbon hydroxylase inhibitors. They may also inhibit the binding of NUCLEIC ACIDS to BENZOPYRENES and related compounds. The designation includes all isomers; the 7,8-isomer is most frequently encountered.
Compounds that contain a BENZENE ring fused to a furan ring.
A fungistatic compound that is widely used as a food preservative. It is conjugated to GLYCINE in the liver and excreted as hippuric acid.
A white crystalline compound prepared by condensation of benzaldehyde in potassium cyanide and used in organic syntheses. This should not be confused with benzoin gum from STYRAX.
Selective renal carbonic anhydrase inhibitor. It may also be of use in certain cases of respiratory failure.
Morphine derivatives of the methanobenzazocine family that act as potent analgesics.
Compounds of four rings containing a nitrogen. They are biosynthesized from reticuline via rearrangement of scoulerine. They are similar to BENZYLISOQUINOLINES. Members include chelerythrine and sanguinarine.
An aniline dye used as a disinfectant and an antiseptic agent. It is weakly fluorescing and binds specifically to certain proteins.
Derivatives of benzophenone (with the structural formula phenyl-(C=O)-phenyl).
Compounds with a core of fused benzo-pyran rings.
A drug-metabolizing, cytochrome P-448 (P-450) enzyme which catalyzes the hydroxylation of benzopyrene to 3-hydroxybenzopyrene in the presence of reduced flavoprotein and molecular oxygen. Also acts on certain anthracene derivatives. An aspect of EC 1.14.14.1.
A class of chemicals that contain an anthracene ring with a naphthalene ring attached to it.
Benzene rings which contain two ketone moieties in any position. They can be substituted in any position except at the ketone groups.
Heterocyclic compounds of a ring with SULFUR and two NITROGEN atoms fused to a BENZENE ring. Members inhibit SODIUM-POTASSIUM-CHLORIDE SYMPORTERS and are used as DIURETICS.
Compounds with a benzene ring fused to a thiazole ring.
OXAZINES with a fused BENZENE ring.
A peroxide derivative that has been used topically for BURNS and as a dermatologic agent in the treatment of ACNE and POISON IVY DERMATITIS. It is used also as a bleach in the food industry.
A chromogenic substrate that permits direct measurement of peptide hydrolase activity, e.g., papain and trypsin, by colorimetry. The substrate liberates p-nitroaniline as a chromogenic product.
An enzyme substrate which permits the measurement of peptide hydrolase activity, e.g. trypsin and thrombin. The enzymes liberate 2-naphthylamine, which is measured by colorimetric procedures.
The benzoic acid ester of choline.
A sympathomimetic agent with properties similar to DEXTROAMPHETAMINE. It is used in the treatment of obesity. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1222)
A centrally active muscarinic antagonist that has been used in the symptomatic treatment of PARKINSON DISEASE. Benztropine also inhibits the uptake of dopamine.
A benzyl-indazole having analgesic, antipyretic, and anti-inflammatory effects. It is used to reduce post-surgical and post-traumatic pain and edema and to promote healing. It is also used topically in treatment of RHEUMATIC DISEASES and INFLAMMATION of the mouth and throat.
A colorless liquid with a sharp burning taste and slight odor. It is used as a local anesthetic and to reduce pain associated with LIDOCAINE injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutic aid, and in perfumery and flavoring.
Alcohols derived from the aryl radical (C6H5CH2-) and defined by C6H5CHOH. The concept includes derivatives with any substituents on the benzene ring.
Benzene derivatives that contain a benzyl group with the general formula Phenyl-CH2-R.
1,1'-Bis(phenylmethyl)4,4'-bipyridinium dichloride. Oxidation-reduction indicator.
An aspect of monoamine oxidase, EC 1.4.3.4. Catalyzes the oxidation of benzylamine to form benzaldehyde, ammonia and hydrogen peroxide.
Toluenes in which one hydrogen of the methyl group is substituted by an amino group. Permitted are any substituents on the benzene ring or the amino group.
QUATERNARY AMMONIUM COMPOUNDS based on BENZYLAMINES with the general formula phenyl-CN+R3.
Compounds which include a double-bonded carbon atom that is directly attached to a benzene ring. While this category is named after the highly reactive compound benzylidene, the compounds listed under it occur through a variety of synthetic pathways.
ISOQUINOLINES with a benzyl substituent.
Analogs or derivatives of bephenium (N,N-dimethyl-N-(2-phenoxyethyl)benzenemethanaminium).
A long-acting calcium-blocking agent with significant anti-anginal activity. The drug produces significant coronary vasodilation and modest peripheral effects. It has antihypertensive and selective anti-arrhythmia activities and acts as a calmodulin antagonist.
The Barberry plant family of the order Ranunculales, subclass Magnoliidae, class Magnoliopsida. The shrubs have spiny leaves.
An alkaloid from Hydrastis canadensis L., Berberidaceae. It is also found in many other plants. It is relatively toxic parenterally, but has been used orally for various parasitic and fungal infections and as antidiarrheal.
A group of related plant alkaloids that contain the BERBERINE heterocyclic ring structure.
A plant genus in the family BERBERIDACEAE. The common names of Barberry or Oregon Grape are also used for MAHONIA. The similar-named Bayberry is the unrelated MYRICA. Oregon Grape was classified by Pursh as a Berberis but Nuttall claimed it is different enough to call it a new genus, MAHONIA. Botanists insist on this name while horticulturists stay with Mahonia. They are shrubs with yellow wood and usually three-branched spines at the base of leafstalks. Flowers are yellow, six-petaled and fruit is a berry with one to several seeds. Members contain BERBERINE.
Refers to the whole process of grieving and mourning and is associated with a deep sense of loss and sadness.
