5'-deoxy-5'-S-isobutylthioadenosine [Supplementary Concept]
considered an analog of S-adenosylhomocysteine; structure
Date introduced: January 1, 1977
Anti-Infective Agents
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection.
Antimalarials
Agents used in the treatment of malaria. They are usually classified on the basis of their action against plasmodia at different stages in their life cycle in the human. (From AMA, Drug Evaluations Annual, 1992, p1585)
Antineoplastic Agents
Substances that inhibit or prevent the proliferation of NEOPLASMS.
Heterocyclic Compounds
Cyclic compounds that include atoms other than carbon in their ring structure.
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
Adenosine
A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.
Year introduced: 1972
Deoxyadenosines
Adenosine molecules which can be substituted in any position, but are lacking one hydroxyl group in the ribose part of the molecule.
Year introduced: 1990
Deoxyribonucleosides
A purine or pyrimidine base bonded to DEOXYRIBOSE.
Year introduced: 1973
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.
Year introduced: 1998
Nucleosides
Purine or pyrimidine bases attached to a ribose or deoxyribose. (From King and Stansfield, A Dictionary of Genetics, 4th ed)
Nucleic Acids, Nucleotides, and Nucleosides
Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges).
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.
Purine Nucleosides
Purines with a RIBOSE attached that can be phosphorylated to PURINE NUCLEOTIDES.
Year introduced: 1974
Purines
A series of heterocyclic compounds that are variously substituted in nature and are known also as purine bases. They include ADENINE and GUANINE, constituents of nucleic acids, as well as many alkaloids such as CAFFEINE and THEOPHYLLINE. Uric acid is the metabolic end product of purine metabolism.
Sulfur Compounds
Inorganic or organic compounds that contain sulfur as an integral part of the molecule.
Thionucleosides
Nucleosides in which the base moiety is substituted with one or more sulfur atoms.
Year introduced: 1977
Therapeutic Uses
Uses of chemicals which affect the course of conditions, diseases, syndromes or pathology to benefit the health of an individual.
Year introduced: 2004
Antiprotozoal Agents
Substances that are destructive to protozoans.
Year introduced: 1967
Antiparasitic Agents
Drugs used to treat or prevent parasitic infections.
Year introduced: 1996
