MeSH

prodrug of vidarabine

Date introduced: August 29, 1980

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.

Purines with a RIBOSE attached that can be phosphorylated to PURINE NUCLEOTIDES.

Year introduced: 1974

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).

Year introduced: 1998

Purine or pyrimidine bases attached to a ribose or deoxyribose. (From King and Stansfield, A Dictionary of Genetics, 4th ed)

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

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

Nucleosides containing arabinose as their sugar moiety.

Year introduced: 1979

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

Multiple ring heterocyclic compounds containing two or more rings that share two atoms and one bond in common.
