 Context examples: 

It is a type of adenosine deaminase inhibitor.

(Nipent, NCI Dictionary)

Nelarabine is demethoxylated by adenosine deaminase to become biologically active 9-beta-D-arabinosylguanine (ara-G); ara-G incorporates into DNA, thereby inhibiting DNA synthesis and inducing an S phase-dependent apoptosis of tumor cells.

(Nelarabine, NCI Thesaurus)

Metaproterenol sulfate binds beta-2 adrenergic receptors in bronchial smooth muscle and stimulates intracellular adenyl cyclase, thereby increasing the production of cyclic adenosine monophosphate (cAMP).

(Metaproterenol Sulfate, NCI Thesaurus)

Examples of these include cytidine, uridine, adenosine, guanosine, thymidine, inosine and others.

(Nucleoside, NCI Thesaurus)

Adenosine triphosphate is involved in energy production for metabolic processes and RNA synthesis.

(Adenosine triphosphate, NCI Thesaurus)

An electrocardiographic finding of tachycardia that is usually terminated by the administration of adenosine.

(Adenosine-Sensitive Ventricular Tachycardia by ECG Finding, NCI Thesaurus)

An autosomal recessive deficiency of the purine salvage enzyme adenosine deaminase which results in Severe Combined Immunodeficiency Disease (SCID).

(Adenosine Deaminase Deficiency, NCI Thesaurus)

Any substance that inhibits adenosine deaminase, an enzyme involved with the degradation of adenine in purine metabolism and that acts as a positive regulator of T-cell coactivation.

(Adenosine Deaminase Inhibitor, NCI Thesaurus)

The PAC produces the molecule cyclic adenosine monophosphate (cAMP) when exposed to blue light, which in turn cranks up the glucose-stimulated production of insulin in the beta cell.

Since atrial fibrillation can be caused by a chemical called adenosine, it is believed that caffeine plays a role in suppressing these effects.
