Year introduced: 1976

A family of hexahydropyridines.

Year introduced: AZACYCLONOL was heading 1963-1984

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

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.

Organic compounds containing the carboxy group (-COOH). This group of compounds includes amino acids and fatty acids. Carboxylic acids can be saturated, unsaturated, or aromatic.

Year introduced: 1973(1971)

Derivatives of carbamic acid, H2NC(=O)OH. Included under this heading are N-substituted and O-substituted carbamic acids. In general carbamate esters are referred to as urethanes, and polymers that include repeating units of carbamate are referred to as POLYURETHANES. Note however that polyurethanes are derived from the polymerization of ISOCYANATES and the singular term URETHANE refers to the ethyl ester of carbamic acid.

Year introduced: TYBAMATE was heading 1965-1984 (Prov 1965-1972)

Carboxylic acids that have open-chain molecular structures as opposed to ring-shaped structures.

Year introduced: 1998

Activities which affect organs and systemic functions without regard to a particular disease.

Year introduced: 2004

A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.

Year introduced: 2004(1999)

A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.
