MeSH

isolated from Micromonospora sp. KY7123; structure given in first source

Date introduced: December 11, 1995

Aromatic hydrocarbons that contain extended fused-ring structures.

Year introduced: 2017(1996)

Compounds which contain two or more rings in their structure.

Year introduced: 2005(1974)

A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.

Year introduced: 1998

Naphthalene derivatives carrying one or more hydroxyl (-OH) groups at any ring position. They are often used in dyes and pigments, as antioxidants for rubber, fats, and oils, as insecticides, in pharmaceuticals, and in numerous other applications.

Year introduced: 1973(1972)

Two-ring crystalline hydrocarbons isolated from coal tar. They are used as intermediates in chemical synthesis, as insect repellents, fungicides, lubricants, preservatives, and, formerly, as topical antiseptics.

Organic compounds composed exclusively of carbon and hydrogen forming a closed ring that may be either alicyclic or aromatic.

Year introduced: 1998

Organic compounds containing carbon and hydrogen in the form of an unsaturated, usually hexagonal ring structure. The compounds can be single ring, or double, triple, or multiple fused rings.

Year introduced: 1998

Organic compounds that primarily contain carbon and hydrogen atoms with the carbon atoms forming a linear or circular structure.

Organic compounds that contain a ring structure made up of carbon and one or more additional elements such as nitrogen and oxygen.

Year introduced: 1998

Cyclic compounds that include atoms other than carbon in their ring structure.

Compounds with a 5-membered ring of four carbons and an oxygen. They are aromatic heterocycles. The reduced form is tetrahydrofuran.
