ozanimod [Supplementary Concept]
a modulator of both S1P1 and S1P5 receptors
Date introduced: May 20, 2016
Sphingosine 1 Phosphate Receptor Modulators
Agents that affect the function of G-protein coupled SPHINGOSINE 1-PHOSPHATE RECEPTORS. Their binding to the receptors blocks lymphocyte migration and are often used as IMMUNOSUPPRESSANTS.
Year introduced: 2020
Indans
Aryl CYCLOPENTANES that are a reduced (protonated) form of INDENES.
Year introduced: 1991(1975)1963-1967
Azoles
Five membered rings containing a NITROGEN atom.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
Heterocyclic Compounds, 1-Ring
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
Hydrocarbons
Organic compounds that primarily contain carbon and hydrogen atoms with the carbon atoms forming a linear or circular structure.
Hydrocarbons, Aromatic
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.
Hydrocarbons, Cyclic
Organic compounds composed exclusively of carbon and hydrogen forming a closed ring that may be either alicyclic or aromatic.
Indenes
A family of fused-ring hydrocarbons isolated from coal tar that act as intermediates in various chemical reactions and are used in the production of coumarone-indene resins.
Year introduced: 1968
Organic Chemicals
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.
Oxadiazoles
Compounds containing five-membered heteroaromatic rings containing two carbons, two nitrogens, and one oxygen atom which exist in various regioisomeric forms.
Oxazoles
Five-membered heterocyclic ring structures containing an oxygen in the 1-position and a nitrogen in the 3-position, in distinction from ISOXAZOLES where they are at the 1,2 positions.
Polycyclic Compounds
Compounds which contain two or more rings in their structure.
Year introduced: 2005(1974)
Polycyclic Aromatic Hydrocarbons
Aromatic hydrocarbons that contain extended fused-ring structures.
Year introduced: 2017(1996)
Physiological Effects of Drugs
Activities which affect organs and systemic functions without regard to a particular disease.
Year introduced: 2004
Immunosuppressive Agents
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
Year introduced: 1966(1964)
Immunologic Factors
Biologically active substances whose activities affect or play a role in the functioning of the immune system.
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
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)
