Adenosine-2-carboxamide (ACA) is a potent and selective adenosine A2A receptor ligand with high affinity and selectivity. This drug has been shown to be a competitive antagonist of the adenosine A2A receptor with an IC50 of 0.8 nM and was highly selective for this receptor over the other adenosine receptors. ACA has also been shown to inhibit binding of radioligands to the adenosine A2A receptor in functional assays, as well as improve binding activity in cell-based assays. These results were confirmed by in silico studies that showed ACA to have high binding affinity, low off-target activity, and good pharmacokinetic properties.

Cytidine 5'-monophosphate is a nucleotide that is important in the synthesis of DNA and RNA. It is a precursor to uridine monophosphate (UMP) and uridylic acid (UDP).

Cytidine 5'-monophosphate also has inhibitory properties against energy metabolism and protein oxidation in bowel disease. This nucleotide has been shown to increase the rate constant for polymerase chain reaction (PCR) by up to 10-fold.

N6-Acetyladenosine is a nucleoside that belongs to the group of N-acetylated adenosines. It is found in thermophilic organisms and has been shown to be involved in optimal growth. N6-Acetyladenosine has also been found to be an important part of the coding and population modifications of crenarchaeota, archaeal organisms that are phylogenetically related to methanogens. Unfractionated populations of methanogen contain both N6-acetyladenosine residues and other modified adenosines, with each organism differing in the types of modifications they contain. Transfer of these modified adenosines from one organism to another can lead to changes in their coding and population modifications.
