2-(4-Fluorophenyl)acetamide (FFAA) is a broad-spectrum antiviral drug that has been evaluated against picornavirus, enterovirus, and rhinovirus. FFAA has been shown to be effective in the treatment of acute enterovirus infections in mice. This compound was also found to have a cytopathic effect on cells infected with enteroviruses in culture. It binds to the virus's RNA-dependent RNA polymerase and prevents viral replication. FFAA is not active against influenza A or B viruses, but it is active against influenza C virus. This compound has also been found to have medicinal properties, as it can inhibit the growth of human lung cancer cells in culture and may be useful for treating cancers such as leukemia.

3-Oxa-7-azabicyclo[3.3.1]nonane is a linker that contains a hydroxyl group, heterocycle, intramolecular hydrogen, and fluorine. It has been shown to be an effective inhibitor of the HIV protease enzyme in vitro, although it is not active against other enzymes such as the human serum albumin or cytochrome P450. 3-Oxa-7-azabicyclo[3.3.1]nonane binds to the active site of the HIV protease by forming hydrogen bonds with amino acids near the active site and by stabilizing the conformation of its piperidine ring. This drug also has an axial orientation with respect to its fluoroquinolone plane and benzyl group that makes it stereoisomeric with 2 possible configurations: cis or trans.

Imidazo[4,5-b]pyrazine is a chemical compound that binds to calcium ions and has been used in the treatment of metabolic disorders. The symptoms of imidazopyrazine include fatigue, weight loss, fever, chills, and muscle aches. Imidazopyrazine is also used for the treatment of autoimmune diseases such as rheumatoid arthritis. In vitro assays have shown that it activates macrophages and lymphocytes and may be useful in the treatment of skin lesions caused by an infection. Imidazopyrazine has been found to have pharmacokinetic properties with a half-life of 3 hours when administered orally. This drug has also been shown to have biological activity against rat liver microsomes.

Benzo[d][1,2,3]thiadiazole is a benzothiadiazole with a redox potential of -0.25 V that is stable in the absence of oxygen and light. It can be used to synthesize chemical pesticides by reacting with hydrochloric acid. The reaction mechanism of benzo[d][1,2,3]thiadiazole has been determined using nuclear magnetic resonance spectroscopy and quantum chemical calculations. This compound reacts with hydrogen bond acceptors on the enzyme active site to form covalent bonds. It also interacts with the enzyme's steric environment by forming hydrogen bonds and van der Waals forces. Benzo[d][1,2,3]thiadiazole also emits light when it reacts with nitric oxide in solution.
