N6-Methyladenine is a modification of adenine in DNA. It is formed by the methylation of the N6 position of adenine, which is a group P2 purine base. The structural analysis of this compound has been studied using x-ray diffraction data, and it has been found that it may inhibit cancer cells by modifying their DNA. This compound can also be used as an antimicrobial agent to treat infections caused by eukaryotes such as bacteria and fungi. N6-Methyladenine may be useful in transcriptional regulation and cellular transformation.

8-Cyclopentyl-1,3-dimethylxanthine (CPT) is a xanthine derivative that binds to the adenosine receptor and inhibits the phosphodiesterase enzyme. CPT is used in vivo as a model for measuring locomotor activity, dopamine receptors, adenosine receptors, and glutamate receptors. The binding of CPT to these receptors can lead to bronchoconstriction by stimulating the release of vasoactive substances from airway cells and increasing the sensitivity of airway cells to bronchoconstrictor stimuli. This drug also has been shown to inhibit calcium ion influx into cytosol and increase intracellular levels of cAMP.
