Staurosporine
An indolocarbazole that is a potent PROTEIN KINASE C inhibitor which enhances cAMP-mediated responses in human neuroblastoma cells. (Biochem Biophys Res Commun 1995;214(3):1114-20)
Year introduced: 1997
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.
Year introduced: 1975(1964)
Indolizidines
Saturated indolizines that are fused six and five-membered rings with a nitrogen atom at the ring fusion. They are biosynthesized in PLANTS by cyclization of a LYSINE coupled to ACETYL COENZYME A. Many of them are naturally occurring ALKALOIDS.
Year introduced: 2008
Indole Alkaloids
Group of alkaloids containing a benzylpyrrole group (derived from TRYPTOPHAN).
Year introduced: 2002
Indolizines
Year introduced: 1966
Indoles
Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.
Heterocyclic Compounds, 3-Ring
A class of heterocyclic compounds that include a three-ring fused structure. Both aromatic or non-aromatic ring structures are included in this category.
Year introduced: 1998
Heterocyclic Compounds, 2-Ring
A class of heterocyclic compounds that include a two-ring fused structure. Both aromatic and non-aromatic ring structures are included in this category.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
Carbazoles
Benzo-indoles similar to CARBOLINES which are pyrido-indoles. In plants, carbazoles are derived from indole and form some of the INDOLE ALKALOIDS.
Year introduced: 1969
Alkaloids
Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant and Hackh's Chemical Dictionary, 5th ed)
Heterocyclic Compounds, Fused-Ring
Multiple ring heterocyclic compounds containing two or more rings that share two atoms and one bond in common.
Year introduced: 2017
Molecular Mechanisms of Pharmacological Action
Pharmacological activities at the molecular level of DRUGS and other exogenous compounds that are used to treat DISEASES and affect normal BIOCHEMISTRY.
Year introduced: 2008(2004)
Pharmacologic Actions
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)
Chemical Actions and Uses
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.
Year introduced: 1999
