pyridoxal (65-22-5, 66-72-8)
Pyridoxal is one form of vitamin B6. Some medically relevant bacteria, such as those in the genera Granulicatella and Abiotrophia, require pyridoxal for growth. This nutritional requirement can lead to the culture phenomenon of satellite growth.
Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint John's wort). Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.
Pyridoxamine is one form of vitamin B6. Chemically it is based on a pyridine ring structure, with hydroxyl, methyl, aminomethyl, and hydroxymethyl substituents. It differs from pyridoxine by the substituent at the 4-position.
Tasosartan is an angiotensin II receptor antagonist. It was withdrawn from FDA review by the manufacturer after phase III clinical trials showed elevated transaminases (a sign of possible liver toxicity) in a significant number of participants given the drug.
Demex · isopropylphenazone · Hewedolor propy
Propyphenazone is a derivative of phenazone with similar analgesic and antipyretic effects.
Tribunil · N-(2-benzothiazolyl)-N,N'-dimethylurea
Phenylindanedione · Dindevan · 2 Phenyl 1,3 indandione
Phenindione is an anticoagulant which functions as a Vitamin K antagonist. Phenindione was introduced in the early 1950s. It acts similar to warfarin, but it has been associated with hypersensitivity reactions, so it is rarely used and warfarin is preferred.
2,4-dimethylphenol titanium (+4) · 2,4-dimethylphenol potassium · 2,4-DMP
p-chlorophenylamine · p-chloroaniline · para-chloroaniline
4-Chloroaniline is an organochlorine compound with the formula ClC6H4NH2. This pale yellow solid is one of the three isomers of chloroaniline.
pyrazon · Pyramin · 1-phenyl-4-amino-5-chloropyridazin-6-one
Hemel · Hexamethylmelamine · Hexalen
Altretamine (trade name Hexalen) is an antineoplastic agent. It was approved by the U.S. FDA in 1990.
1,2,5,6-dibenzanthracene, ion(1+) · 1,2,5,6-dibenzanthracene · dibenz(a,h)anthracene
Dibenz[a,h]anthracene is an organic compound with the chemical formula C22H14. It is a polycyclic aromatic hydrocarbon made of five fused benzene rings. It is a fused five ringed, cyclopenta, PAHs compound which is common as a pollutant of smoke and oils.
N(4)-acetylsulfamethoxazole · N(4)-acetylsulphamethoxazole
Sencor · Lexone · Zenkor
Metribuzin (4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one) is an herbicide used both pre- and post-emergence in crops including soy bean, potatoes, tomatoes and sugar cane. It acts by inhibiting photosynthesis by disrupting photosystem II. It is widely used in agriculture and has been found to contaminate groundwater.
Biphenyl (92-52-4, 68409-73-4)
diphenyl · diphenyl, 14C-labeled
Biphenyl (or diphenyl or phenylbenzene or 1,1′-biphenyl or lemonene) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl. It has a distinctively pleasant smell.
Lamictal · 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine · Labileno
Lamotrigine, sold as the brandname Lamictal among other, is an anticonvulsant medication used to treat epilepsy and bipolar disorder. For epilepsy, this includes focal seizures, tonic-clonic seizures, and seizures in Lennox-Gastaut syndrome. In bipolar, it is used to treat acute episodes of depression, rapid cycling in bipolar type II, and prevent recurrence in bipolar type I.
