The chemical reactions and pathways involving purine nucleobases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.

The chemical reactions and pathways resulting in the formation of AMP, adenosine monophosphate.

The chemical reactions and pathways involving D-ribose (ribo-pentose). As beta-D-ribofuranose, D-ribose forms the glycose group of all ribonucleosides, ribonucleotides and ribonucleic acids, and also of ribose phosphates, various glycosides, some coenzymes and some forms of vitamin B12.

Any process which produces a nucleotide, a compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety, from derivatives of it without de novo synthesis.

The chemical reactions and pathways involving purine nucleobases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.

The chemical reactions and pathways involving purine nucleobases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.

Any process that generates adenosine, adenine riboside, from derivatives of it without de novo synthesis.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

That part of the nuclear content other than the chromosomes or the nucleolus.

That part of the nuclear content other than the chromosomes or the nucleolus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.

An extracellular matrix lying external to fungal cells. The fungal biofilm matrix consists of polysaccharides, proteins, lipids, and nucleic acids. Fungal biofilms mediate adherence to host tissues, and provide protection from host immune defenses.

All of the contents of a cilium, excluding the plasma membrane surrounding the cilium.
