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.

Prenyletin methyl ether is a flavonoid compound, which is a naturally occurring polyphenolic molecule sourced primarily from specific plant species. This compound exerts its effects through a variety of biochemical interactions, notably influencing cellular signaling pathways, including antioxidative and anti-inflammatory processes.

Vaginidiol is a coumarin derivative that inhibits the biosynthesis of estrogen, which is essential for normal development of female reproductive tissues. The structure of vaginidiol was elucidated by NMR and mass spectroscopy, and it was found to be a bergapten-coumarin derivative. Vaginidiol has been shown to have an inhibitory effect on the growth of plants. This compound can be synthesized in two steps from etoac extract by an asymmetric synthesis using potassium hydroxide as the catalyst.

4-Aminoquinoline-2-one is a nonsteroidal anti-inflammatory drug that has tuberculostatic activity. It binds to the nitrogen atoms of the enzyme dihydropteroate synthase, which is involved in the synthesis of folic acid and DNA. This leads to an increase in reactive oxygen species and inflammation, which causes disease activity. 4-Aminoquinoline-2-one has been shown to be synergistic with monoclonal antibodies when used as a treatment for inflammatory diseases. In order for 4-aminoquinoline-2-one to be taken up by cells, it must bind to cellular uptake proteins through hydrogen bonds or disulfide bonds.

4-Methylquinoline is a natural compound that is structurally related to coumarin. It serves as an enzyme substrate for various types of enzymes, and has been shown to inhibit the activity of enzymes such as N-acetyltransferase, indoleamine 2,3-dioxygenase, and tryptophan 2,3-dioxygenase. 4-Methylquinoline has also been shown to be effective against infectious diseases such as toxoplasmosis and leishmaniasis. Furthermore, 4-methylquinoline has been shown to have anti-inflammatory properties in autoimmune diseases such as multiple sclerosis. The mechanism of action of 4-methylquinoline is not fully understood but it may interfere with the production of nitric oxide by inhibiting the enzyme nitric oxide synthase.

5-Hydroxyquinolin-2(1H)-one is a chalcone that can be synthesized from 2,5-dihydroxybenzaldehyde and quinoline. It is a bacteriostatic agent that inhibits bacterial growth by binding to the 50S ribosomal subunit, blocking the formation of an antibiotic-substrate complex with the enzyme cell wall synthesis that is required for cell wall biosynthesis, inhibiting protein synthesis and cell division. 5-Hydroxyquinolin-2(1H)-one has shown activity against methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant Enterococcus faecium. 5-Hydroxyquinolin-2(1H)-one also represses the expression of DNA topoisomerase II genes, which may be associated with its inhibitory effects on bacterial growth.
