Adenosine 3'-phosphate 5'-phosphosulfate lithium, an adenine nucleotide derivative, is a selective P2Y1 antagonist with no effect on P2Y2, P2Y4, or P2Y6 receptors. Adenosine 3'-phosphate 5'-phosphosulfate lithium can competitive inhibit ADP-induced platelet aggregation, as well as the ability of ADP to cause shape change and increases in Ca²⁺ in platelets, but had no effect on the inhibition of stimulated adenylate cyclase by ADP. Adenosine 3'-phosphate 5'-phosphosulfate lithium is a co-substrate used for the sulfonation of glycans. Adenosine 3'-phosphate 5'-phosphosulfate lithium can be used for Golgi-resident PAP-specific 3'-phosphatase-coupled sulfotransferase assays, which as donor substrate to transfer a sulfonate group.

Guanosine 5'-triphosphate-5'-adenosine (GpppA), a 5′ cap analog, can be used for RNA synthesis in vitro. Guanosine 5'-triphosphate-5'-adenosine is a fluorescent substrate analog.

2'-Deoxyadenosine-5'-triphosphate (dATP) is a nucleotide used in cells for DNA synthesis (or replication), as a substrate of DNA polymerase.
