chemical compound

TRISPHAT (full name tris(tetrachlorocatecholato)phosphate(1−)) is an inorganic anion with the formula often prepared as the tributylammonium () or tetrabutylammonium ( salt. The anion features phosphorus(V) bonded to three tetrachlorocatecholate () ligands. This anion can be resolved into the axially chiral enantiomers, which are optically stable (the picture shows the Δ enantiomer).

Masoprocol is an antineoplastic drug used to treat skin growths caused by sun exposure. It is the meso form of nordihydroguaiaretic acid that is taken by mouth. The substance is being studied in the treatment of prostate cancer.

Fustin, sometimes called "dihydrofisetin", is a flavanonol, a type of flavonoid. It can be found in young fustic (Cotinus coggygria) and in the lacquer tree (Toxicodendron vernicifluum).

chemical compound

A-86929 is a synthetic compound that acts as a selective dopamine receptor D1 agonist. It was developed as a possible treatment for Parkinson's disease, as well as for other applications such as treatment of cocaine addiction, but while it had reasonable efficacy in humans it also caused dyskinesias and has not been continued. It has mainly been used as its diacetate ester prodrug adrogolide (A-93431; ABT-431; DAS-431), which has better pharmacokinetics.

6-Hydroxycyanidin is an anthocyanidin.

Tretoquinol is a beta-adrenergic agonist.

chemical compound

Melacacidin is a chemical compound related to leucoanthocyanidins. It can be found in Acacia crassicarpa.

chemical compound

Capsazepine is a synthetic antagonist of capsaicin. It is used as a biochemical tool in the study of TRPV ion channels.

Higenamine (norcoclaurine) is a chemical compound found in a variety of plants including Nandina domestica (fruit), Aconitum carmichaelii (root), Asarum heterotropioides, Galium divaricatum (stem and vine), Annona squamosa, and Nelumbo nucifera (lotus seeds).

Europinidin (Eu) is an O-methylated anthocyanidin. It is a water-soluble, bluish red plant dye. It is a rare O-methylated flavonoid, a derivative of delphinidin. It can be found in some species of Plumbago and Ceratostigma.

3,4-Dihydroxyphenylacetaldehyde (DOPAL), also known as dopamine aldehyde, is a metabolite of the monoamine neurotransmitter dopamine formed by monoamine oxidase (MAO).

A-77636 is a synthetic drug which acts as a selective D1 receptor full agonist. It has nootropic, anorectic, rewarding and antiparkinsonian effects in animal studies, but its high potency and long duration of action causes D1 receptor downregulation and tachyphylaxis, and unlike other D1 full agonists such as SKF-82,958, it does not produce place preference in animals. A-77636 partially substituted for cocaine in animal studies, and has been suggested for use as a possible substitute drug in treating addiction, but it is better known for its use in studying the role of D1 receptors in the brai

chemical compound

SKF-77,434 is a drug which acts as a selective dopamine D1 receptor partial agonist, and has stimulant and anorectic effects. Unlike other D1 agonists with higher efficacy such as SKF-81,297 and 6-Br-APB, SKF-77,434 does not maintain self-administration in animal studies, and so has been researched as a potential treatment for cocaine addiction.

chemical compound

Luteoforol is a chemical compound belonging to the flavan-4-ol class of flavonoids.

Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O-glucoside of luteolin.

Nitecapone (INN; OR-462) is a drug which acts as a selective inhibitor of the enzyme catechol O-methyl transferase (COMT). It was patented as an antiparkinson medication but was never marketed.

Quinalizarin or 1,2,5,8-tetrahydroxyanthraquinone is an organic compound with formula . It is one of many tetrahydroxyanthraquinone isomers, formally derived from anthraquinone by replacement of four hydrogen atoms by hydroxyl (OH) groups at the 1, 2, 5, and 8 positions.

Chloroethylnorapomorphine is a chemical once thought to be an irreversible dopamine D2 receptor antagonist; however, it was later proved to be reversible.

3,4-Dihydroxystyrene (DHS) is a centrally-acting inhibitor of the enzyme phenylalanine hydroxylase (PH). It is likely that DHS and other PH inhibitors will never have clinical applications on account of their capacity for inducing hyperphenylalaninemia and phenylketonuria.
